Kilowatt Cards are gift cards that can be redeemed to pay for 10 kilowatt-hours anywhere in the world. Electric utilities don't accept them - we do - at www.kilowattcards.com, and then send payments directly to the utilities at the rate they normally charge residential customers for the same amount of electricity, including taxes and fees.
Since they can be used to pay for anyone's electricity, kW Cards are useful to barter for other things - and as a store of value - worth a fixed amount of energy regardless of electricity prices.
They have fixed value because 10 kWh is a physical constant one can evaluate intuitively: 10 kWh = 10,000 Watt-hours, enough energy to run a 100 Watt light bulb for 100 hours (exactly) and roughly enough to drive a Toyota Prius 25 miles. Gasoline has 36.6 kWh/gal. 10 kWh costs about $1 - $2.
The purpose of kW Cards is to save human labor in a form that cannot be taken away through currency inflation. If electricity-backed notes are redeemable at face value then one cannot loose wealth to inflation (but one can, for example, save a stable asset that is less expensive than land). Such notes represent collective ownership of the underlying assets but in a liquid form.
System value is protected by linking issuance of new kilowatt-hours to the purchase of commodities such as firewood and grain - things that represent real labor and energy. That way something more than fiat money is involved in their creation. We limit the price paid for electricity to a multiple of the world average, weighted by population, so places with high prices but small populations like rural Alaska cannot threaten the system.
Joe Stiglitz has predicted that all national currencies will eventually fail due to inflation, and be replaced by private currencies from competing companies, backed by gold and their reputations. But electricity offers a unique alternative. It is a standard, pure product (120V, 60 Hz; U.S.)
While any power producer could issue its own electricity-backed notes, the chances for a local system failure due to war or to fuel shortages are high. But a delocalized system like Kilowatt Cards transforms these physical risks into a financial question. And since redemption of a delocalized scrip does not depend on any given electric utility, it can function as a stateless medium of exchange.
Commerce in kilowatt-hours provides a way to compare values. A lawyer billing $200 per hour is compensated at 20,000 hours of light per hour (at 10 cents/kWh; 100 Watt bulb). The electricity standard could reestablish a link between wages and the value created by disparate forms of work.
Pyramid schemes promise returns to all investors. kW Cards pay no interest, and promise no return unless redeemed, then pay only for the face amount of electricity, and only to someone else, the power utility.
