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 buy levitra on the internet 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 environmentally benign substances, batteries usually are not.

By combining the quick-charge and large storage capability of canadian drug viagra soft 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 levitra pharmacy 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 "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 each problem they encounter.  I expect one to be in my ultra-slim phone within the decade.

Capacitors are quite thoroughly capable of discharging as quickly or slowly as you would like. This is for the same reason that light bulbs (And TVs, computers, etc...) don't explode when you turn them on, in spite of the countless gigawatts flowing across the electrical grid.

The part that troubles them is 50mg viagra uk cheap energy density; both in terms of buy cialis online pharmacy energy per mass and energy per volume they come in unfavorably against batteries. Improvements are being made (Look up "ultra capacitors"), but there's still a long way to go.

Completely aside from that, you don't always want something to viagra fedex overnight shipping charge as quickly as possible. If the process of storing energy in a capacitor or battery is, say, 99% efficient and you store 650MJ of energy (Comparable to 20 gallons of gasoline burned in a 25% efficient Otto cycle engine) in it over the course of 5 minutes, then you'll be producing 21,670 watts of heat while recharging. That's quite a lot of heat to get rid of, and that's not even going into the stress on the infrastructure (Both in terms of the charging location and the cheap levitra tablets grid itself) resulting from having a 0.002KW consumer spike to 2.167MW for 5 minutes.
I mean, the only reasonable way to handle that kind of load would be to use ANOTHER storage system designed to charge throughout the day and then release it all at once (Again, with a charging inefficiency), which would require a constant load of no less than 7.523KW for a full charge over the course of 24 hours.
Obviously most people will not run down their cars completely every day, but a well designed system shouldn't choke on periods of high usage.

Mobile devices don't require nearly as much power as a car, but if you've ever heard of an exploding laptop or phone or even felt your phone get hot from use, then you can imagine what kind of problem waste heat can become even for small devices.

I'm trying to make a similar project here. I want to make a solar-powered plastic battery. Do you know any ways to help me achieve this??? thanks a LOT.... please reply smilies/cheesy.gif you would make a junior pass high school
