Laptop Battery Breakthrough Promises Lighter Weight, More Power

mit lightweight laptop batteries Laptop Battery Breakthrough Promises Lighter Weight, More PowerBetter battery life is on the top of most people’s gadget wish lists. Now, a technology breakthrough from MIT offers hope for the mobile masses — but it will have to contend with other experimental approaches in a race to the market that could take years, experts say.

MIT researchers say they have found a way to create batteries that can offer up to three times the energy density of current batteries, while being much lighter. That paves the way for portable devices that could both be lighter and have a much longer battery life than current gadgets.

“You can get laptop battery life in a laptop computer similar that’s three times more than what you have now, even as the battery gets three times lighter, ” Yang Shao-Horn, associate professor of mechanical engineering and materials science at MIT, told

While advances in material sciences and chip design have led to more powerful computers with better displays, battery life has remained a big roadblock. That’s why new battery technologies have become a major area of research. Companies such as GE and IBM are exploring the promise of a new kind of battery called lithium-air. These batteries could replace existing lithium-ion batteries.

Lithium-air batteries have a lithium anode that is electrochemically coupled to atmospheric oxygen through an air cathode. By contrast, current lithium-ion batteries have a carbon anode and a metal oxide-based cathode.

“There’s huge potential for lithium-air batteries,” says Vishal Sapru, industry manager for power and energy system at research firm Frost & Sullivan. “The combination of lithium anode and air cathode not only makes them lighter than lithium-ion but also offers higher energy density.”

Sapru estimates that a typical lithium-air battery can offer an output of 1800 watts per kilogram compared to about 120 to 350 watts per kilogram seen in lithium-ion APPLE A1078 Battery.

But so far, there has been a lack of understanding about the kinds of electrode materials that could promote the electrochemical reactions that take place in lithium-air batteries, which has held back their development, says MIT’s Shao-Horn.

The answer, she says, according to her team, lies in using gold or platinum as a catalyst.

And despite the bling factor, batteries using these precious metals could still be cost competitive, says Shao-Horn. “We need to have only the surfaces covered by these elements,” she says. “We are not using platinum and gold in the bulk of the HP 395794-001 Battery.”

It’s an interesting breakthrough, agrees Sapru, but one that’s by no means guaranteed a commercial future. Other battery researchers are working on other materials, such as aluminum-polymer laminates, for instance. What will eventually reach the hands of consumers remains to be seen, he says.

“Till these technologies reach commercial manufacturing stage we can’t reliably tell how they will do in terms of costs and accessibility,” says Sapru. “While gold and platinum offer some advantages, aluminum-polymer laminates can be more flexible, so we will have to wait and see.”

Shao-Horn says her team’s ideas are still a long way from commercialization. The group is yet to perfect the chemistry of the charging and discharging processes and increase efficiency of the system, she says.

“Ultimately, just like we have different types of lithium-ion batteries today,” says Sapru, “we will have different lithium-air batteries. But all of this is a couple of years away from reaching consumers.”

How to manually upgrade your Android smartphone and tablet

A one-size-fits-all guide to updating your device to a newer software version

We all want the most up-to-date gadgets and therefore the most recent versions of the software that is available for them. Upgrading an Android device might take you to a newer version of the operating system like 4.0 Ice Cream Sandwich or bring new features or enhancements for your Dual sim smartphone or tablet.

Upgrades for Android devices are generally available over-the-air (OTA) which avoid the need for cables and a PC. They also rolled out gradually and will depend on the manufacturer and mobile operator. You may receive a notification about an upgrade but you can also manually check and upgrade your device.

Here’s a one-size-fits-all guide to upgrading an Android smartphone or tablet.

Step One

As a precautionary measure it’s good practice to back up your data such as contacts and photos. The upgrade should not affect your data but there is no guarantee.

Step Two

Navigate to the Setting menu of your device. On any Android device this can be done via the app menu. Typically the Setting app will have a cog or spanner logo.

Top 4 Websites To Find Free iPad Books

As much as some people want to ignore it, it seems that eBooks are here to stay. This does not mean, of course, that paper books are gone for good, and I personally still like them very much, but it’s hard to withstand the availability and speed with which one can get one’s hands on an eBook.

While not being as fun as paper books or as easy on the eyes as other dedicated eReaders, the iPad provides a good way to read thousands of eBooks without buying another specialized device. Below I mention several websites where you can find loads of free iPad ebooks.

Note that most of the free books you can get are those that are now in the public domain, meaning they are mostly by dead authors or have become public domain for other reasons. If you’re looking to get the latest big bestseller, you probably won’t find it for free on these websites to find iPad books.

In order to view these books on your iPad you’ll need an eBook app like iBooks. Simply add the .epub files to your iTunes library and sync them to your iPad. The books will automatically appear in iBooks.

Project Gutenberg

 Top 4 Websites To Find Free iPad Books

Project Gutenberg might not be the best website to look at, but I guess that’s because they’re concentrating on what’s really important, and that’s bringing us  lots of free books! It has pretty good search and browse options, and if you know what you’re looking for, finding it should be a breeze. There’s also a Top 100 list that should help if you don’t really know what you’re looking for.

This site offers eBooks in 7 different formats (including ePub, PDF, Kindle and several others). When I downloaded the ePub version on “Alice in Wonderland”, I got a file named “pg11″, which wasn’t very helpful. The book also didn’t come with a proper cover (or artwork, if you wish), so that was a bit boring, and this was the case for other books I downloaded through this site as well, but the books themselves were all there.

 Top 4 Websites To Find Free iPad Books

Project Gutenberg also offers an offline catalog of their books, so if you want to sit and look through it while you’re not connected to the internet, you can do so easily. You can also find books in many other languages, with 14 languages boasting more than 50 books to download!

 Top 4 Websites To Find Free iPad Books

On first glance, ManyBooks‘ design is better than Project Gutenberg, and definitely more “modern”, but after I tried playing with it a little, I found their interface a bit confusing. ManyBooks offers, well, many free books, and you can get those in numerous formats, some that I’ve never even heard of before.

 Top 4 Websites To Find Free iPad Books

Just browsing through their titles or authors gets a bit confusing, but searching works well. If you need help finding a book, there’s a “recommended” section and a “new titles” section. The “new” titles are, of course, new to the site, but not to the world. I also found a weird mix of English and non-English books in the same place, which didn’t help my confusion at all.

I chose to download “Through the Looking Glass”, which came with the helpful file name of “carrollletext91lglass19epub”, but the book did come with a cover picture, which was nice.


This site is a great improvement when it comes to looks. It’s very nice to look at, all the books have cover pictures and I found myself browsing it for much longer. I guess I’m a sucker for good looks.

ePubBooks offers many free books, but it also points you to places where you can get paid books. There aren’t many formats to download here, as you can guess from the name, but when looking for iPad books, this is not a problem. I chose to download the book “A Christmas Carol”, and the file name included both the name of the book and the author’s name in a way I could actually read it. Big plus! The file (and others I tried) did not, however, contain a cover picture for the book.

 Top 4 Websites To Find Free iPad Books

This site lets you browse and search, like all other sites, but it also lets you browse by genre. This is not new by any means, but what I loved about it is that ePubBooks actually explains what each genre means. Dropping genre names is all nice and dandy, but it’s great to know what they mean by those names.

 Top 4 Websites To Find Free iPad Books


FeedBooks is different from the other websites in that it has its own eBook store, which could be useful to some. This also means that you need to be wary, because many of the suggestions they give on their main page are for paid books. You can choose to look only at free books, and there is also an “Original books” category, which is interesting.

 Top 4 Websites To Find Free iPad Books

The book I chose to download came with a book cover image, and the name of the file was the best of all the sites I tried: “H. G. Wells – The War of the Worlds”. This is what it should look like! This by itself, for me, is a winning feature. As far as I could see, this website offers books in the ePub format only. It’s a very easy site to browse through, and it even has an RSS feed you can subscribe to which will let you know about new releases.

 Top 4 Websites To Find Free iPad Books

If you’re looking for books in other languages, though, this might not be the site for you. While other sites offer books in numerous other languages, FeedBooks offers book in only 4 languages (English, French, German and Spanish). But if you’re looking for books in these languages, you should definitely give this site a spin.


All these websites deliver what I was looking for, which is free iPad books. It’s hard to say which one is the best, as they all have some good features, and, of course, free books! But as all books are the same, I will tend to use the website that offers the best browsing experience, and that was FeedBooks. Having a coherent file name on download didn’t hurt either.

So where do you get your free books? Is there a really good website we missed? Let us know in the comments!

iPhone 5′s Battery, Back Camera and Audio Flex Cable

Apple’s iPhone 5 is knocking at the doors, its design has been finalized, its production has made its pace, and the flood of leaked parts has also set its way to tech blogs. It is much expected that the iPhone 5 supply chains would reveal more and more leaked parts and information before the iPhone 5 sees the day light in September/October. Recently, an iPhone parts supplier TVC Mall has posted a few new purported iPhone 5 parts including the Battery, Back Camera Lens, and Headphone/Earphone Audio Jack Flex Cable.

These new leaked parts are quite different from the parts currently used in iPhone 4. Here is a side-by-side comparison of these parts with images of iPhone 4 parts, courtesy of aussiebattery.

iPhone 5 iPhone 4 Battery iPhone 5s Battery, Back Camera and Audio Flex Cable

No significant change seems there in iPhone 5 battery as it is almost same in size and shape to the cell phone battery that we have in existing iPhone 4 device. Both iPhone 5 and iPhone 4 batteries also have the same power specs as iPhone 5 battery is labeled as 3.7V and 5.3Whr while the iPhone 4 battery shows 3.7V and 5.25Whr.

The new part also grabs a reasonable part number of 616-0580 as compared to the iPhone 4′s 616-0513 and 616-0521 part numbers while the connector on the iPhone 5 battery is rotated contrary to the iPhone 4 part.

Toshiba satellite a100 battery – Brand New 4400mAh Only AU $61.68

Now come to iPhone 5 back camera module that exhibits a closely embedded camera flash similar to the iPhone 4′s design. It negates all the previous rumors that describe; iPhone 5′s camera may be separated from the camera module, or suggest dual LED flash for iPhone 5. It is expected that The iPhone 5′s would be equipped with an 8 mega pixel camera, upgraded from the 5 mega pixel camera incorporated in the existing iPhone 4.

iPhone 5 iPhone 4 Camera iPhone 5s Battery, Back Camera and Audio Flex Cable

As with all these early iPhone 5 parts, the supplier website has scant details on the specifications. In fact, we doubt that they even know the specifications at this stage. Some dimensions do seem to be given for the parts, but when compared the dimensions for known parts (such as the iPhone 4 battery) on the same site, there seemed to be a wide discrepancy against other published specs we’d found on the internet. So, we can’t put much faith in the listed dimensions.

Finally, comes the new leaked part of iPhone 5- An Audio Jack Flex cable. At present, we are not in position to say much about it, though it looks very different from the cable we have been using in current GSM and CDMA parts.

Top 5 ways to squeeze more battery out of your laptop

We’ve all been there: you’re in the middle of something on your laptop and you get the warning to back up your information because it’s about to run out of juice. To reduce the odds of that happening, take heed to these simple tips.


HP laptop battery Top 5 ways to squeeze more battery out of your laptop
It has happened to many a traveler: you’re onboard a flight from, say, Vancouver to Montreal, with plans to finish the stack of work tucked into your laptop case.

After all, an airplane is often a great place to be productive, thanks to the absence of nagging colleagues, email and ringing phones — providing, of course, the battery technology you need is in working order at 30,000 feet.

Sometimes, you barely make it over Edmonton before your computer warns you it’s about to “hibernate” as you’re battery power is at just five percent. Now how exactly do you plan to finish that sales report before you land?

Unless the airline you fly has AC power in the seat, you’re S.O.L.

Energy management has been a problem since the earliest days of mobile computing. Thanks to more powerful batteries and processors with better energy management, it’s getting better all the time, though there’s still no magic-bullet solution.

But there are some things you can do aside from lugging a spare laptop battery. The following are a few tips for squeezing more juice out of your laptop:

1. Turn down the brightness of your monitor a great deal as it will help preserve battery life. This can usually be found on your laptop’s secondary keyboard commands (such as blue icons that look like little suns) and then manually reducing the brightness. When you’re near an electrical outlet again — at home, the office or in a hotel – then crank the brightness back up, if you like. If you’re shopping for a new laptop, keep in mind the bigger the laptop screen the faster the battery drain, in most cases.

2. The Asus A32-F3 Laptop Battery will drain faster if there’s a spinning disc in your optical drive such as a game, music CD or DVD movie. Some games offer you the choice to install it all to the hard drive so choose this option as you’ll get more life out of your laptop. Same with music and movies – copy your favourite tunes to the hard drive instead of spinning the CD or use the “Digital Copy” option on the last Blu-ray or DVD flick you purchased. Needless-to-say, your laptop computer battery will last much longer in programs with little drain on system resources, such as a word processor.

3. Make sure you have no devices plugged into the laptop that can be draining its power, such as a webcam, USB thumbstick or headphones. Connected peripherals can be a factor in eating away at its battery life, so get used to the touchpad instead of using an external mouse when you’re away from an electrical outlet. Ditto for enabling wireless connectivity, such as Bluetooth and Wi-Fi, so be sure these radios are turned off when you don’t need them (they should be turned off in an airplane, anyway!).

4. Windows users can also click on Power Options in the Control Panel to manually reduce the power consumption of your laptop. Some may turn off your monitor when not in use for, say, 3 minutes, but will turn on instantly again when a key is touched. Also, you can also set alarms when the battery is about to die (say, at 5 percent) so you can safely save your information before powering down. Also, per above, if you’re in the market for a new laptop, be sure to choose a processor that does well on energy management (do your research) like the Intel Core family.

5. While not cheap, you might want to consider a better (or second) battery than the one that shipped with your PC. For example, HP laptops typically ship with a regular 6-cell laptop battery that can deliver up to four or so hours of battery life, depending on the application. But you can choose to buy an 9-cell battery that can last up to 10 hours on a single charge or a 12-cell Smart Lithium-Ion Ultra-Capacity battery – for just under 16 hours of battery life.

Top 5 Essential OS X Mountain Lion Tips

Perhaps you’ve upgraded your Mac to Mountain Lion, but have you turned on all the best features? Make sure you’re not missing out on all the ways OS X 10.8 can interact with iOS devices, from iPads to the new iPhone 5.

 Top 5 Essential OS X Mountain Lion Tips Apple users, who may be thinking this week about getting ready for a new iPhone and mobile operating system, will do well to make sure their Macs are up to date. Assuming you’ve already installed Apple OS X 10.8 Mountain Lion ($19.99, 4.5 stars), there are a few features and options you’ll want to make sure you’ve enabled to fully take advantage of the operating system. You’ll get more out of your Mac when it’s set up to interact with your iPhone, iPad, and other Apple devices.

 Top 5 Essential OS X Mountain Lion Tips

Turn On iCloud

To take advantage of how Mountain Lion syncs and interacts with your iPhone, iPad, or other Apple devices, you have to turn on iCloud.

iCloud has many uses, including backup, but for the purpose of this article, let’s look at using it for syncing. Part of what makes OS X 10.8 Mountain Lion special is that you can start something on your mobile device and finish it on your Mac, practically seamlessly. Previous versions of OS X do support iCloud, too, but with Mountain Lion, you’ll see even more features that leverage iCloud in some neat ways.

You’ll find iCloud on your Mac in Settings, the same place you can find it on your iPhone and iPad. The first step is to simply log in with your Apple ID. Make sure you turn on iCloud on all the devices where you want to use it.

 Top 5 Essential OS X Mountain Lion Tips

Turn on the various apps that you want to sync. If you use the Contacts apps on your iPhone or iPad, I definitely recommend turning it on in Mountain Lion, as some of the other apps and services will leverage your Contacts list. I also recommend most users sync Safari bookmarks, Calendar, Reminders, and Notes, too. Plenty more apps and services sync, of course, so turn on the ones you prefer. And with iOS 6 (coming later in September), photos can be shared with your contacts automatically, if you’ve set up iCloud’s Photo Stream.

(Note: If you have Apple mobile devices but use a Windows computer, you can still use a lot of iCloud’s services and features, but not all of them. For some features, Apple gives you a Windows alternative; for example, you can sync bookmarks between Internet Explorer and iOS devices.)

Set Up iMessage

iMessage is by far one of my favorite features in Mountain Lion, and it replaces the old iChat. iMessage is Apple’s messaging service that optimizes texting by bypassing SMS when it can. On an iPhone or an iPad, it’s part of the Messages app. What iMessage does is improve messaging between Apple devices. When you send messages between iPhones, iPod touches, and iPads running iOS 5 or later, iMessage prioritizes sending and receiving the messages via Wi-Fi when it’s available and through 3G when it’s not.

 Top 5 Essential OS X Mountain Lion Tips

When you’re on your laptop or Mac computer running Mountain Lion, you can pick up your text conversations right where you left them—except for messages from non-Apple users that came in as SMS texts on your phone, unfortunately. You can also see new messages come in on your computer, which is better for productivity than moving away from the keyboard and screen to view incoming messages on a phone or tablet. Another reason I love iMessage is it supports AIM, Yahoo!, Google Talk, and Jabber, letting you merge Messages with systems you’re already using. Also would be nice if it tied in with FaceTime, since the old iChat did video.]

To set up iMessage, go to the app and log in with your Apple ID.

To get the most out of iMessage, you’ll want to use Contacts (Apple’s address book) to store phone numbers, handles, and email addresses of the people with whom you will likely swap messages, iMessage integrates cleanly with that data. Type a few letters of a person’s name, and within a few clicks, you can be text-chatting. However, you don’t have to use your Contacts list. You can also type a phone number of an iPhone into the “to” field and start a message. That’s something you couldn’t do with iChat, and it’s central to the whole concept of renaming the app Messages.

Turn On FaceTime

FaceTime is Apple’s video chat app. Once you have iCloud handling all your contacts, FaceTime becomes much more usable, so be sure to turn on iCloud and sync your contacts first to be sure you have everyone’s email addresses on hand.

Setting up FaceTime is a snap. When you launch the app, it will prompt you to log in with your Apple ID (or another email address if you prefer). From there, it’s just a matter of figuring out who else among your friends, family, and business associates uses the program. You can choose their names from the contact list that shows up in the app. It doesn’t matter if your friends are using FaceTime to make or receive video calls from their Macs, iPads, iPhones, or iPod touches, and when iOS 6 rolls out (September 19), mobile users will be able to access FaceTime over their cellular networks as well—not just over Wi-Fi as was previously the case.

Enable Twitter

Across Apple products, we’ve seen Twitter become more tightly integrated with the operating system itself rather than just apps. Mountain Lion is no exception. The idea is that you should be able to share various goodies, such as URLs and photos, to Twitter in just a click or two.

 Top 5 Essential OS X Mountain Lion Tips

To set up Twitter, you can either turn it on in the Settings, or just log into Twitter from your machine, and Mountain Lion will suggest enabling it automatically.

Coming soon, according to Apple, we’ll see the same kind of integration with Facebook. Apple’s iPhoto software already integrates pretty neatly with Facebook, letting you not only share photos to the social networking in a snap, while also letting you keep an eye on the activity that happens around those images after you share them. iOS 6 will also tie Facebook into its basic sharing services, so do expect to see more information about this feature in the near future.

Customize Alerts

Once you have iMessage turned on, you’ll want to make sure the app notifies you of incoming messages in the manner you want. To customize alerts from iMessage, as well as from other apps, you’ll need to hit up the Notifications section of the Settings.

 Top 5 Essential OS X Mountain Lion Tips

You can turn on or off alerts for a number of different apps and services, as well as change where they appear on the screen and what (if any) sound they include. The “alerts” option (shown in the image above) will put you notifications in a collapsible right pane on the screen.

 Top 5 Essential OS X Mountain Lion Tips

In my testing, I’ve found that the most useful alerts come from iMessage and Calendar, but you can also turn them on for incoming Mail, Twitter activity, Reminders app reminders, Game Center activity, Facetime calls, and more.

Get Ready for iOS 6

The single biggest change from OS X 10.7 Lion to OS X 10.8 Mountain Lion was just how much tighter the desktop operating system became with the mobile operating system. And with iOS 6, Apple users will see a few more improvements in terms of how their mobile devices work in collaboration with OS X—just one more reason to make sure you customize Mountain Lion to take advantage of all that the system offers.

While putting the final touches on the HTC One X software, HTC’s developers managed to place an application in the wrong directory, causing some issues for the Tegra 3 power battery management software on the HTC Style Phone. The misplaced NvCPLSvc.apk file was discovered in the /system/bin folder by mike1986 while developing a custom ROM for the HTC One X. To correct HTC’s mistake, users can push the file to /system/app via ADB. Those who have already tried this fix are reporting a 10-20 percent improvement in battery performance on the HTC One X.

Over the past few days, we’ve heard rumors that HTC has been prepping an update for the HTC One X to enhance its Acer aspire 4720 battery performance. There’s no guarantee that HTC’s fix will address this specific issue, but we’d definitely understand if you don’t want to take fate into your own hands when an official fix may only be days away.

Testing Lithium Titanate Batteries –

Lithium Titanate Batteries Face Testing

A Portland-based battery developer is rolling out a new battery technology and letting power customers kick the tires. EnerSol Energy Systems Solutions’ push to find early adapters to put lithium titanate batteries to the test is part of an increased focus on grid storage and electric vehicles.

The three-man company focuses on consulting and product development in batteries and energy systems for electric vehicles, grid storage, and portable devices. It posts annual revenues of less than $500,000 and has partnerships among battery suppliers and manufacturers worldwide.

Now reaching out to energy companies, utilities, hospitals, cellular phone companies, IT server rooms and fire stations, EnerSol is looking for partners interested in developing and testing lithium titanate batteries as a back-up power supply for use in large scale energy storage applications or for use in semi trucks and other larger, commercial scale vehicles that can accommodate its size.

The company has a particular interest in testing the technology as a backup to renewable energy generators like wind and solar farms. Batteries can store excess power while generation is high and demand low. They can also help mitigate the stress of mass consumer power use during peak hours and give operators greater flexibility in power sales.

EnerSol’s product comes forward as observers predict the market for grid storage is poised to balloon. The market was pegged at $5.6 billion in 2010 in a report from GTM Research, and the company speculated the market would grow to $9.6 billion by 2015.

Positioning for market-share in grid storage is a key objective for EnerSol and other battery makers.

Batteries are just one of the technologies being eyed for large-scale grid storage, along with fly wheels, compressed air, hydrogen, pumped water, thermal and superconducting magnetic energy systems.

In a game where costs and lifespan limit solutions, the objective is on to find affordable technologies that will last. Among battery makers, there is stiff competition to prove out the best technology.

EnerSol president Doug Morris said the company’s recent demonstration project is designed to show customers what lithium titanate can do.

A modified lithium-ion laptop battery — lithium ion batteries are used in cell phones, laptops and most consumer and portable electronic products — the battery uses an electrochemical version of lithium ion, lithium titanate, instead of carbon, making for fast recharging and high currents.

The battery itself is supplied by suppliers Toshiba and PHET and developed for grid and vehicle uses by EnerSol.

Morris said the result is a battery that charges 5 to 10 times faster than lithium-ion batteries and lasts beyond 25,000 charging cycles, or about 10 to 20 times longer than lithium iron phosphate batteries (used in power tools and cars).

Though lithium ion batteries are cheapest to build, at 60 cents or less per watt-hour, their short life cycle means they would need constant replacement if assembled for grid storage. That makes lithium titanate competitive at $1.15 per watt-hour, Morris said, given its long life span.

Spying opportunity, EnerSol has developed three table-top, 20 amp-hour, 12 volt demonstration batteries valued at $30,000 to lure beta trials.

“What we’re really hoping for is to get enough interest in the demo so that people can test the technology,” said Morris. “It’s great to tell people about a new technology, but when you can actually give them one to test and try they say, ‘Oh, I get it,’ and can talk about what they want to do with it.”

The demo is a piece of where the EnerSol vision could lead. The batteries can be built small, like the tabletop unit, or assembled in packs that fill multiple trailers, storing multiple kilowatts per trailer. They are controlled by a simple, menu-driven software and control module developed by Denmark-based vehicle-battery developer Lithium Balance, for which Morris is involved in developing a U.S.-based headquarters. The package is a slimmed-down version of Lithium Balance’s robust system that’s used in its electric vehicle batteries to balance the charge and temperatures across cells in a battery pack through a system that interfaces with a PC computer.

Morris, whose career stretches 30 years in the battery world, much of it developing technology for Motorola, said battery development was previously focused elsewhere, fine-tuning different chemistries for particular functions. Lithium ion batteries, for example, were established as a best fit for portable devices like cell phones and computers for their long-lasting charge, he said. And lithium phosphate batteries were deemed most suitable for electric vehicles for their safety performance.

“Now, with storage… people are trying to figure out what the best chemistry is,” Morris said.
