Could Sugar Replace Lithium Ions?

jolt cola
The meaning of juicing up your iPod may soon become a lot more literal. Researchers at Saint Louis University have developed a fuel cell battery that runs on virtually any sugar source - from soft drinks to tree sap - and has the potential to operate three to cialis professional sale four times longer on a single charge than conventional lithium ion batteries.

The new battery, which is completely biodegradable, could eventually replace lithium ion batteries in many portable electronic applications, including computers. The findings were described today at the 233rd national meeting of cheap tramadol sales 120 tabs the online viagra utah American Chemical Society in Chicago.

This study shows that renewable fuels can be directly employed in batteries at room temperature to lead to more energy-efficient battery technology than metal-based approaches.
It demonstrates that by bridging biology and genuine viagra online chemistry, we can build a better battery that's also cleaner for the environment. Study leader Shelley Minteer, Ph.D.

A few other researchers also have developed fuel cell batteries that run on sugar, but Minteer claims that her version is the longest-lasting and most powerful of its type to date. If the battery continues to show promise during further testing and refinement, it could be ready for commercialization in three to five years, she estimates.

Consumers aren't the only ones who stand to benefit from this new technology. The military is interested in using the sugar battery to charge portable electronic equipment on the battlefield and in emergency situations where access to electricity is limited. These devices include remote sensors for detecting biological and chemical weapons. Devices could be instantly recharged by adding virtually any convenient sugar source, including plant sap, Minteer said.

Like other fuel cells, the sugar battery contains enzymes that convert fuel - in this case, sugar - into electricity, leaving behind water as a main byproduct. But unlike other fuel cells, all of the materials used to very good site levitra in uk build the sugar battery are biodegradable.

So far, Minteer has run the batteries on pill price propecia glucose, flat sodas, sweetened drink mixes and tree sap, with promising results. She also tested carbonated beverages, but carbonation appears to weaken the fuel cell.

Wiicharging the only now sale cialis Wiimote

Being the greenest and whitest next-gen console, the Wii is an obvious choice for the EcoGeek. However, if you have one, you know that finishing the 70-hour Zelda or perfecting your swing in Wii Sports takes a killing in the battery department. With four controllers and addicting gameplay, batteries stack up quickly in price and cialas waste. Unfortunately, the Wii and extra remotes comes with two toxic, disposable alkaline batteries no matter what, but there are some good alternatives around.

Thankfully accessory manufacturers see the problem too and are releasing various rechargeable Wii remote batteries and chargers. The most practical ones are dual remote charging stations like Nyko’s Wii Charge Station and Joytech’s Wii Power Station that let you recharge without taking out the batteries. They come with two batteries that form the bottom half of the controller and the order cheap tramadol no prescription needed battery itself. These replace the original Wii battery cover and fit into the battery slot. Like a wireless phone, the remotes are charged simply by being placed into the charging station. Nyko and Joytech’s stations come with two slots so two remotes can be charged at a time. Also if you prefer the single player experience, Brando is producing a single nunchuck-remote holder and charging station.

If you don’t mind the inconvenience of taking the batteries out to charge, conventional rechargeable batteries work with the Wii also and thankfully there’s new innovations going on there. Sanyo’s eneloop and Rayovac’s Hybridrechargeable batteries have been out for a few months and getting positive reviews. Both use advanced NiMH technology to last longer than regular rechargeables and they work right out of the box. Lastly, the USBCELL USB rechargeable batteries that we’ve heard so much about work great for the Wii since it has a USB port on it. It will only let you charge one at a time though since two won’t fit in the Wii, but it’s still a convenient (and space saving) alternative.

The Volt's Batteries? A123 Systems

Are the batteries for the Volt here already? If GM wants to get new technology into a car within the next five years, the batteries need to be ready today so that they can get into the business of making them cheaper and high-performance in series. 
And if the batteries are here today, it is click here buy discount viagra online likely that the nanoscale electrode A123 li-ion batteries are them. These things have higher power density, lower weight, won't explode in an accident and opperate from -20 to 140 degrees Fahrenheit.  These batteries are already being used in power tools. Interestingly, hobbyists have already started using those power-tool batteries to create their own electric cars.
Signs seem to the best place buy viagra in canada no prescription be pointing to A123's batteries as the source of the power for GM's next generation hybrids and levitra levitra beyond. Not the least of visit our site cialis tablet those signs is the tramadol online overnight announced partnership between A123 and GM. All of this adds up to a pretty positive scenario for the Chevrolet Volt. The only question now is: how long before these things cost less than $10,000 a pack? 

Altair Nanotech. Delivers Batteries to Phoenix Motorcars

altairnanoThe first ten batteries have been delivered to Phoenix Motorcars from Altair Nanotechnologies. These lithium ion packs use a new ceramic nano-material that, while lowering the power density, makes the batteries much safer. Altair says that the batteries can be over-charged with a nail driven through them and they still won't explode.

Adding to our suspicion that the Phoenix Sport Utility Vehicle will be rather expensive, the cost of the tof the first shipment was roughly $750,000. However, most of that so it's hard to imagine that these vehicles will be available for less than the $100,000 Tesla pricetag. But most of that has to getting cialis from canada be engineering fees. The per-battery cost has not yet been released, but is probably between $15,000 and $20,000 a piece. They will have a smaller pricetag and a longer range than any other EV on the road, but they will be more expensive and have a shorter range than any similar gasoline powered car.

Unfortunately, reports that the Phoenix SUT was the perfect electric car are premature. But it is a step in the right direction. The new batteries can also charge extremely rapidly at 400 volt charging stations, but will take several hours to charge at a residential outlet.

The Mystery of Bloom Energy

EDITOR'S NOTE: This article is from 2006. To see our take on Bloom Energy from a 2010 perspective, check out our new article
Bloom Energy: Should you Believe the Hype?
Since hearing that John Doerr and the CEO of Bloom Energy are going to be appearing together on Charlie Rose, I've been putting some pieces together. First, KPCB, Doerr's venture capital firm, has been saying repeatedly, "we've been investing in some very interesting alternative energy opportunities."We know that they've funded Eestor, who makes the long-charge supercapacitors that will be powering the cheap tramadol buy online Zenn city travelers. But we also knew that that couldn't be all their investing in. KPCB is one of these multi-billion dollar venture capital firms, and they've been (very intelligently) focusing on clean technology recently.

After a bit of research, I'd like to offer some speculation about what Bloom Energy will be doing.

We already know about the technology the company is based on. In short, K. R. Sridhar created a kind of very good site cheap levitra online prescription fuel cell that can combine water, oxygen and viagra available in india an energy source, like natural gas or ethanol, to produce power extremely efficiently.

My guess is that that the profitability of these devices lies in distributed power.

I think Bloom Energy is looking to install 100 Kilowatt power units in everyone's houses. These will be flex-fuel, but likely running mostly on natural gas. They will also probably produce heat, and cooling, as well as power, making the devices roughly 85% efficient (thus generating two times less greenhouse gas emissions than a power plant per unit of power used.)

I don't want to say that they will also be used to create hydrogen, but the technology allows for the fuel cell to easily produce hydrogen if 100% of it's power isn't needed. This could then be used to fill up your new Honda FCX. As a last piece of wild speculation, I will ask: If these units have such wonderful energy densities and efficiencies, could we put one in a car?

Bloom Energy's current website says absolutely nothing about anything. But, it does finish up with a pretty picture of the earth and the tagline "Be the Solution," which lends credence to we use it buy cialis online without prescription everyone having their own super-efficient little power plant in their basement.
I can't wait to hear what K.R. Sridhar has to say for himself tonight on buy kamagra Charlie Rose.
