How energy storage can make green energy economical

Its interesting that in Oct the price of electricity in Tx dropped to 0 (for brief time). They were basically giving it away because there isn't a way to store it. http://cleantechnica.com/2011/10/20/wholesale-price-of-elect...
Aquion is definitely an exciting competitor, and we wish them all the best. It is an honor to have such a worthy competitor. I think we'll bring out the best in each other.
They probably can reach the smallest scales better than we can, though I think we're going to give them a run for their money at mid - larger scales. It will be a challenge to come up with a system nearly so low cost and long lasting as one using compressed air. There are also some very interesting things we can do with low-grade heat, but that is another story. :-)
Granted, even a little negative doesn't mean you'll make money by turning on all the lights and cranking the A/C. Distribution charges and etc usually add a few cents per kWh.
Offpeak Energy + Storage < Peakers + Grid Upgrades
Promote the green solution (and save green!) :)
Also, we have a pretty awesome team already, but we're always looking for exceptional people. jobs@lightsailenergy.com :)
We have a breakthrough energy storage technology called Regenerative Air Energy Storage.
The concept is to store energy in compressed air -- a motor/generator first drives a compressor, which stores air in a tank. To deliver stored energy, the air comes out and is expanded, driving the motor/generator as a generator and generating electricity.
Our innovation captures the heat energy of compression (the majority of the energy in compressed air is stored in the form of heat) and allows us to regenerate from it almost all of it in the form of useful energy.
We do this by spraying a fine water mist directly into the compressing and expanding air. The high surface area and heat capacity of water rapidly absorbs the heat of compression, and delivers it during expansion, to be converted back into mechanical energy.
It always made sense in my mind to decrease loss before increasing availability.
Great idea to razor focus by lightsail.
