I came across this today.
Kilowatt Cards: a store-of-value and a medium-of-exchange
Kilowatt Cards are gift cards that pay for 10 kilowatt-hours of electricity (including taxes and fees) to benefit any consumer electricity account when redeemed though this web site. The electric utility does not accept Kilowatt Cards - we do - and then send cash payment to the company at the rate it normally charges retail customers for electricity.
Because these gift cards may be redeemed by anyone to pay for electricity, they can also be used to barter for other things, anything, worldwide. Kilowatt Cards are issued by a non-profit corporation founded to demonstrate the idea that financial liabilites denoted in kilowatt-hours constitue a new asset class having stable value, and to provide fixed-value paper to those who want it.

Make any sense??
