USB Chargeable Batteries

 usb battery
Until that micro gas-turbine power supply is available, here's a standard size AA battery that can be recharged using its built-in USB port on a computer or other powered USB port. They are rated at 1300mAH. While there may be others with more capacity, it's hard to beat the convenience of buy prescription levitrabuy levitra in the uk the included USB connector.

Moixa Design, the makers of the battery, also have plans for future versions including AAA and C/D size, 9 volt, and cellphone and cialis generic canada handheld device sized batteries. For now, these are only available in the UK, but expect them to spread quickly and be available in your particular part of the globe before long.

If doing away with the charger isn't green enough for you, the manufacturer sweetens the i recommend beta blockers and viagra deal even more with a free recycling program for their batteries.

Fuel Cell to Power Portables

  Mobion Portable Fuel Cell

It doesn’t look like we’ll be getting rid of our wireless devices anytime soon. In fact, the number of portable electronic devices we use is on the rise. In response to this trend, MTI Micro has created Mobion power packs. Based on direct methanol fuel cell (DMFC) technology, the Mobion technology is a truly wireless solution, potentially liberating us from slavishly plugging in our chargers to power outlets. Instead, refill the fuel cell with neat (100%) methanol to recharge the battery. By removing the need for water to be externally pumped from the cathode to the anode side for the viagra alternatives chemical reaction to occur and energy to be produced, their technology improves on the traditional approach to micro fuel cell design. The result is a lighter weight, compact and efficient fuel cell that hooks directly onto the device.

As is often the case with new technologies, the first planned applications for the technology are in the military, government and industrial portable electronics markets. But with a partner list that includes Samsung Electronics, Gillette/Duracell, DuPont and Flextronics consumer applications can’t be far behind.

Switching from Batteries to Portable Power Generation


Our needs for portable power keep growing. Electrical and electronic devices are great, and the features and functionality they provide continues to expand. But none of these devices are worth anything without the power to make them work.

In addition to some of the other new battery technologies we've recently featured, there are some portable power generation methods. First, nano-engines could generate electricity efficiently from small amounts of viagra online canada no prescription fuel.  And second, small fuel cells can producing power from hydrogen gas. Both of these use some kind of fuel (hydrogen, alcohol, or hydrocarbon in liquid or gas form) to run the system and generate electric power.

The miniature engine is the project of a group of researchers at MIT. They recently announced that they have fabricated all the components necessary to produce micro scale gas-turbine engine that could provide 10 times longer life than a comparable weight of batteries (storage per kilogram.)

Creating these micro-turbines uses the buy levitra where same etching technology used to legal online cialis create computer chips. While the individual components have been developed, the next step is to get all of the components working together to demonstrate the abilities and effectiveness of the device.

Simultaneously, development is continuing on canada viagra prescription micro fuel cells as another promising avenue of canadian levitra scam development. Like larger scale fuel cells being developed for automotive use, these systems produce electricity directly when fuel is cheapest viagra uk supplied to a catalyst. There are already some fuel-cell projects in the works, including cell phone chargers, and portable lights. 

The move from power storage to power generation could be a powerful shift for portable electronics as well as for the automotive industry.  Creating fuel-powered electric cars might seem like a step backward, but not when the fuel is hydrogen, and the power per kilogram is so very high.

300 Watt-Hours per Kilogram!

thinfilmbatteryLithium ion batteries are great.  They've taken us miles beyond traditional non-rechargeable batteries. But, and you might have heard about this, they sometimes explode.  They're also reaching the limit of their capacity per kilogram.  One hundred fifty watt-hours per kilogram is a great number for a Li-Ion battery, but in the tech world, everything needs to double every few years, and if we're not going to do it with Li-ion batteries, we need to find something new.

And thin film batteries are certainly something new.  The batteries are actually composed of flat layers of pure lithium electrodes and an electrolyte bonded to a glassy surface.  The batteries never lose charge, can withstand extremes of heat and cold, can charge quickly and discharge slowly or quickly an infinite number of times, can pack a ton of power into a small space, and will not explode in your lap if you dent them.

Increasing the power to kilogram ratio is extremely important, not just in mobile computing, but also for electric driving, where the weight of batteries is a huge problem.  Lighter electric batteries means less electricity is needed to cialis professional 100 mg power the car, and so the car can go further, faster, and weigh less. 

Thin film batteries are, of course, currently far to expensive for retail.  But if Silicon Valley has taught us anything, it's that a technology in demand never stays expensive for too long.

Plastic Battery: Instant Recharge


Bateries are electrochemical cells that have an ion gradient between two chemical compounds.  Capacitors are two pieces of metal placed very close to one another so that a charge can store up between them.  Capacitors charge and discharge extremely quickly.  Batteries are slow to re-charge, if they re-charge at all, but can discharge slowly and under control.  Capacitors can hold a large amount of power per square inch, batteries cannot.  Capacitors are usually made of purchase viagra in budapest environmentally benign substances, batteries usually are not.

By combining the quick-charge and large storage capability of a capacitor, with the slow controlled discharge of a battery, we could have an entirely new class of battery that is much more environmentally sound.  That's what researchers at Brown University say they've done. 

It's no simple matter, I won't try to explain it (head to physorg, or for more info,) but  I can explain the effect it would have on consumer electronics.  Smaller batteries, extremely rapid charge time, and, get this, it's flexible and about the thickness of an overhead transparency.  No more poisonous power packs that occasionally explode.  No more overnight charging and viagra no perscription uk "CRAP I forgot to charge my cell phone!" moments. 

There are some obstacles still to overcome, the capatery holds less and less charge each time it is re-charged.  But it's a new technology, and there will be hundreds of solutions to viagra australia each problem they encounter.  I expect one to be in my ultra-slim phone within the decade.
