ok so when submitting my water pump instructable i saw the competion for paper coffee cups, this gave me some ideas but the closing date is the 9th, today is the 9th (at 2.26am) so i dont have time to get hold of a bunch of paper coffee cups and i dont think it would be in the spirt of the thing just to get a load and waste them. so i have done some diagrams to demostrate my idea.
when i was in school back when i was 16 years old i was asked to design a wind mill for charging batterys, it was a spectacular failure, since then i have thought how it could be done much better. this challenge has bought me back to that idea.
