Ultra-capacitors are also called Super-Capacitors – they are the new emerging energy storage technology. Currently they are being used for applications such as DC motor drives, UPS systems, and electric vehicles.

Alternative EngineeringLet’s go back to 1993 when United States President Bill Clinton challenged US automakers to “Think Different”:  President Clinton was surrounded by the CEO’s of General Motors, Chrysler, and Ford and he said that the US Government was going to help build cars with better fuel efficiency.  He said that their research would lead to production of prototypes vehicles capable of up to three times greater fuel efficiency, for example, “radical new concepts such as fuel cells and advanced energy storage systems such as ultracapacitors, to produce more fuel-efficient cars that are affordable, meet or exceed current safety standards and retain the performance and comfort available today.”

TODAY.. Fifiteen years after President Clinton’s announcement,  ultracapacitors are becoming more mainstream as engineers are now taking a second look at alternative energy engineering. Ultracapacitors outperform batteries in several key parameters such as power density, cycle life and temperature sensitivity.

Many Utltracapacitor designs are also more efficient and can be manufactured more environmentally safe relative to the metals in lead-acid or nickel-cadmium batteries.  

So… If you are an engineer and would like some assistance integrating an ultracapacitor, please drop me an email.  I will find you the expert in this industry to assist. 

Let’s think different!

Please explain the current limit of any combination ultra/mega/uber cap array. Is there a limit? What about cap/battery combinations for high density storage?

Please shoot me an email. I am an engineering student interested in using ultracapacitors for a specific project. I would like some more information. Thanks.

I made a "modular battery" by encasing 10 paired 220F x 2.3v (=4.6v x 550F) with a switch and 2 power jacks. How is it modular? I can daisy chain all modules together for more amp hours (or add together for move voltage) and run 2 devices (any 2 or 3 battery 3-4.5v eater) or 1 device and a charger (solar or 4.5v -12v adapter). So I won't need regular batteries anymore. I got a bunch of ni-cd's and ni-mh to get rid of.

Seems like such an exciting technology and so needed at this time. Just wondered where an engineer wanting to use his God given gift would go assist in getting our country off its' oil dependence.

is it possible to create a "ultra"
for cars or trucks

I wonder if this (ultra capacitors) would fall in line with Senator McCains' 300 million dollar prize for inventing a "next generation" battery?

Please tell me what will "specialized applications " of ultracapacitor consist of ..apart from electric vehicles, mobile devices , UPS and military.??

Currently there are a lot of different applications that are using ultracapacitors. We are working with train using the regen braking. Several solar energy storage and use situations as well as using on wind mills to move the blades to get optimal performance.

Many places where small batteries gave pluses are perfect for ultracaps. Do you have a specific product or application you want looked at?
