Batteries or Capacitors? Tesla CEO Speaks Out

clock March 23, 2011 00:48 by author Jeremy

Elon Musk, CEO of Tesla MotorsElon Musk, CEO of famed motor company Tesla, admits he believes that the long term war of energy in vehicles would be won by capacitors, not batteries. An ironic statement, coming from the man whose business currently utilizes numerous lithium-ion batteries for electric vehicles. It's also a statement with a lot of weight behind it, considering the other accomplishments Musk has in his belt (including having a hand in the creation of PayPal).

"If I were to make a prediction, I'd think there's a good chance that it is not batteries. but capacitors," stated Musk recently while at the Cleanteach Forum in San Francisco.

Currently, batteries continue to be a leading resource for energy throughout the world. Musk's statement, however, is backed by the knowledge behind capacitors and ultracapacitors. For example, unlike batteries, they can withstand more charge / discharge cycles.

More research is needed behind capacitors and ultracapacitors, and before that happens, batteries will continue to provide the energy needed for many electronic devices. But perhaps one day, Musk's prediction that capacitors "will supercede" batteries will come true.

HTC Thunderbolt and Kyocera Echo, Released March/April 17

clock March 16, 2011 01:16 by author Jeremy

Two phones that have been teased around the web for a while now are finally getting official release-statements: Verizon's HTC Thunderbolt and Sprint's Kyocera Echo. The former is going to be the first smartphone on Verizon's 4G LTE network, and will be available March 17 (just two more days!). Meanwhile, the latter smartphone will be out on April 17th (just two more days! ...oh, and a month on top of that).

What's so special about these two, you ask?

As mentioned previously, the Thunderbolt is the first 4G smartphone using Verizon's LTE network, which should provide faster download/upload speeds. The Thunderbolt will come with a 4.3" display, an 8-megapixel rear camera with 720p HD recording, a 1.3-megapixel front-facing camera for video chatting, and the latest 1GHz Snapdragon processor.

This, of course, should be a power-hog, so expect to charge your battery quite a bit. The Thunderbolt has already been delayed several times due to poor battery life, relating to issues around signal strength. These issues have been fixed, and there's even news circulating of an extended battery being offered by HTC, which will have roughly 2750mAh (almost double the phone's stock battery of 1400mAh). The phone-stand also comes back, just for your viewing pleasure.

Meanwhile, on Sprint's end, we'll be seeing the Kyocera Echo, a dual-screen smartphone that offers "simul-tasking". Consumers can use the two screens to simultaneously check their email, text message, browse the web, and more. During the Sprint event in February, they showed how the dual-screen phone could be used for gaming: The Sims was demo'ed with the top screen showing the game, and the bottom screen showing the control buttons. Alternatively, you could also converge both screens together (not physically, of course!) to use them as one large viewing apparatus. Nifty, indeed.

The smartphones of today just keep getting smarter, it seems.



Google Sets Up "Person Finder" In Reponse to Japan Earthquake

clock March 11, 2011 18:27 by author Jeremy

This morning, our thoughts and wishes go out to those who have suffered in the wake of the earthquake that hit Japan recently. The quake, reported at a magnitude of 8.9, has even caused tidal warnings for all those in the pacific area.

Google has set up a "Person Finder" site specifically for this natural disaster. This tool works based on user-fed information, letting others know of who you've seen recently. The database is continuing to grow as news of the site spreads.

Hopefully, the Person Finder will help many separated families and loved ones find each other. Every little bit helps.



Aerogel: Frozen Smoke, or Pure Awesome?

clock March 11, 2011 01:25 by author Jeremy

Well, it certainly looks like something the future would hold, doesn't it? Aerogel, also known as "frozen smoke" (can that name get any cooler?) is currently one of the world's lightest solids. It contains MWCNT - multi-walled carbon nanotubes, which are so small that thousands of them can fit on just one strand oh human hair.

Aerogel currently has many potential uses, ranging from detecting toxic substances to improving robotic surgery. One of these possible applications even includes something that could affect our daily lives: batteries.

Thanks to carbon nanotubes and the large surface area that they provide, aerogel is capable of storing vast amounts of energy. If used in conjunction with present-day batteries (whether they be lithium, alkaline, or other types), the aerogel could very likely increase the capacity that a single battery can hold.

"This has many potential applications and could really open up new areas to explore that we haven't even imagined yet," says Associate Professor Lei Zhai, who worked on the engineering team for aerogel. Along with Zhai were postdoctoral associate Jianhua Zou; University of Central Florida professores Saiful Khondaker, Sudipta Seal, and Quanfang Chen.

Video Tutorial: Removing Your Netbook Battery and Finding Model and Part Numbers

clock March 8, 2011 21:16 by author Ty

In this video, customers are provided an example of how to remove a battery from their netbook. We also demonstrate the two ways customers can find model numbers, with which they can use to find their corresponding replacement laptop battery.

Transcription of the netbook battery removal video.

Jeremy: "Hey everyone, this is Jeremy from eBatts.com, and today I'll be showing you how to remove a battery from a netbook.

This is our HP Mini, which we'll be using for an example today. (flip laptop over to expose bottom-side)

You'll notice that for this particular netbook, there are two battery locking clips located on either side of the battery. Once you push those forward, as indicated by the little arrows here, the battery will begin to pop out, and you can then pull it out.

There are two ways to find your replacement laptop battery. One way is to locate the battery model number, which is listed on the battery itself. As you can see from this example, this is an "HSTNN-LB0D".

The other way is to use the laptop model number itself, which is listed, sometimes, on the bottom of the laptop. In this example, the product is the "HP Mini 110". (flip)

A more common place to find your laptop model number is on the front. Here it is located on the bottom-right corner of the laptop screen.

This concludes our video tutorial on how to find the various model numbers associated with your netbook. For more video tutorials, check out our website at www.ebatts.com/blog."
