Estimated Costs
Sky Windpower estimates that its technology will be capable of producing electricity for $0.02 per KWh, while a system of raising a kite to a high altitude while turning a generator on the ground, and then changing its shape so that it can be drawn back down with less energy than it produced on the way up, has been estimated to be capable of producing electricity for $0.01 per KWh - both numbers being significantly lower than the current price of non-subsidized electricity.

Famous quotes containing the words estimated and/or costs:
“The glory of a great man ought always to be estimated by the means used to acquire it.”
—François, Duc De La Rochefoucauld (1613–1680)
“Pride can go without domestics, without fine clothes, can live in a house with two rooms, can eat potato, purslain, beans, lyed corn, can work on the soil, can travel afoot, can talk with poor men, or sit silent well contented with fine saloons. But vanity costs money, labor, horses, men, women, health and peace, and is still nothing at last; a long way leading nowhere.—Only one drawback; proud people are intolerably selfish, and the vain are gentle and giving.”
—Ralph Waldo Emerson (1803–1882)
