In rural Africa , electricity is voiceless to come by . That ’s why Dr. Cedrick Ngalande has develop theGreen Erg Generator — a dynamo that develop electricity from friction generated with the priming coat while walking .
“ This is basically a dynamo which is being driven as a outcome of clash between the ground and the blocks . The small yellowish block ( these are covered by rubber in the real commercial product ) rotate as you pull it . They are design to rotate even on bumpy turn tail even roads . We have tested it on moist lawns and have worked . It is very smooth so much that you essentially do n’t feel any mental disturbance as you move along .
At normal walk speeds we have gotten more than 2 watts which is more than enough for running cellular phone telephone or radios . I envision that mass will bind this to themselves and walk with it – or even attach it to an ox - handcart , a skating board , bike , etc . ”
It seems nonsensical ( and it certainly look preposterous ) , but rein wasted movement to return electrical energy is an musical theme that has alot of potential drop .
