This is genuinely crazy. Not the whole scientific establishment - just those who have joined the cult of warmingism and abandoned actual science. Cheers! Rich

He can't get more energy out of having the bed and himself descend that he put into it by pulling the bed up and the climbing up himself. Say a bed weights 100kg, an he weighs 75kg, and that the bed is raised by 2 metres. Total energy 3430 Joules, or about 1 Watt-hour. Won't get much lighting out of that. In any case, he'd have to eat marginally more food to account for the exercise, and that's a very inefficient way of turning food into electrical energy. Sylvia.

True, it was just having some fun, a kind of creative art. But he can light his house for almost half an hour. BTW: the bed is for 2 persons and there is some mechanism which turns up very fast, but turns down for about 7 hours. Burning a candle give the same amount of light. -- Ik praat liever tegen een domoor, dan tegen dovemansoren.

Never seen the pictures of melting gletgers? Have you seen the pictures of the North pole over the last few decades? Cheers! -- Ik praat liever tegen een domoor, dan tegen dovemansoren.
