"Can we get them up to 1.21 Gigawatts?"
Well - it many ways it is. I just read about a completely different application of this stuff to build what are called “Ultra Capacitors” These are storage devices that can hold huge amounts of electricity - and they have the advantage over batteries of having 1/10-1/100 the recharge time and 300,000-400,000 recharge cycle life times.
The problem is they still only have about 1/10 the capacity of batteries. If they can move into the same arena as Lead-acid - then electric cars become practical.
You can literally think of driving up to a recharge station and take 10 minutes to recharge your car instead of 4-8 hours.

news flash...electric cars are already very practicle thanks to teslamotors.com. They are using lithium ion batteries for a 200-250 mile range and a 4.5 hour recharge. They can recharge in about 10 minutes but there is some infastructure that needs to be built for that. Their first production roadster is not cheap, $100,000 but they intentionaly did that to get more capitol and come out with a lower cost sedan and then with an even lower cost car affordable to most. This is real and finally about to take off. Their roadsters are sold out, I believe for this year and will be on the road shortly.
