I don't get the attraction after reading this:

Where they're weak, however, is with energy storage. Compared with lithium-ion batteries, high-end ultracapacitors on the market today store 25 times less energy per pound.

This would mean a very heavy pack. I seem to remember hearing something about on TV in an application of a full size electric car. The ultracapacitors were used for burst energy, I think charged up by the vehicles onboard battery.

Where they're weak, however, is with energy storage. Compared with lithium-ion batteries, high-end ultracapacitors on the market today store 25 times less energy per pound.

Doesn't match the statement made above it:

The company boldly claims that its system, a kind of battery-ultracapacitor hybrid based on barium-titanate powders, will dramatically outperform the best lithium-ion batteries on the market in terms of energy density, price, charge time, and safety.

I think the first statement is a general statement made by the author and the second (1st in the article) is a statement from the company.

Edit:

Ah, didn't get to the second page:

For example, the company's system claims a specific energy of about 280 watt hours per kilogram, compared with around 120 watt hours per kilogram for lithium-ion and 32 watt hours per kilogram for lead-acid gel batteries.

Personally, I'll believe it when I see it.

wake me up when I can fly a 50 for 12 minutes consistantly with a battery that is not delicate and costs under $100. We are a LONG way from where I want to be battery wise.
