Capacitors can be made with high ratings already, but what's important is the cost of making them, they have to be cheap to be a contender unless it's for NASA maybe.

If you are going by claims, this is unimpressive. EEstor, another Texas company, claims to have ultracapacitor material more than an order of magnitude better at absorbing electricity than "current commercial ultracapacitors."

The real trick is to get it to market.
