A quantum leap in electrical energy storage
A company called EEStor have filed a patent for a "super capacitor". 31 Farad capacity which can run at 3,500 volts.

In small scale, it should be possible to charge a laptop or mobile phone on a domestic supply in 5 seconds and have two to three times as much energy stored, all in the same size as our current Li Ion batteries. Then since it's a capacitor instead of an electrochemical cell, there's no degradation between charge/discharge cycles.

Solar cells, wind turbines and electric cars could also really benefit from this.

I've written more at my blog

Haha, probably.

It'd be ironic though, because they're best placed to set up high voltage charging stations for all our future electric cars. That is, as long as you can find a safe way of having high voltage supplies and petrol tanks in the same fuelling station!

Yep. Someone had something to say about my "trickle charge over night, then zap your car in the morning" point. If you go back to the comments, it's the last one. I haven't had time to inspect his algebra yet.

It's the "charge your phone in 5 seconds" bit that is getting me rather excited.
