My latest project. Recently I designed a new generation wind turbine. I am going to miniaturize my design and work it into the front trunk area of a teener. My goal is to drive coast to coast non-stop........ Ambitious? Yes! Doable? Yes! I will accept any help thrown my way! (IMG:style_emoticons/default/drunk.gif) By the way, it is great to be back here, I missed this place! |

Man this brings me back..... When I was young and ambitious and considered myself inventive, I came up with a plan similar to this. A perpetually powered electric car. The problem was the need and ability to reliably generate and store more power than you are consuming. Given the needs for accelleration, grade increases, accessory/load demands, I figured that if you allowed for a 25% overhead (100KW generate, 75W motor) and had enough capacity you would be fine, but the math (according to my electrical engineer uncle).
The plan was to generate power two ways, 1 was regenerative through a wheel driven generator, second was solar power cells. The theory/idea was sound, the math diddnt hold up. Something about entropy, etc and that the ratio of consumption to generation wasnt right. I thought a 2-3 speed transmission to step up the ration on the generator would address this, but there was little available to make that happen. So, I decided to scrap the design and went instead for a system with: solar panels (roof & hood), a wheel generator (front wheels) and a small onboard gasoline powered generator (engine compartment) all 3 would dump power into the batteries, solar when the sun was out and independedent of all movement, the wheel generator when moving, and the gas generator for when demand outpaced the ability to generate or the battery levels dropped below 40%. I still liked the idea of a 2 speed transmission to double the speed of the generator relative to speed, the theory being generating twice the power and outpace consumption. This system worked out great on paper and the math worked too. The only problem was I was 13-14 years old and had no access to do anything other than old lawnmower parts, scavanged junkyard parts, and a 1960 VW beetle shell. But this was the 70's, I was 14 and of little means, so I just sent the idea to the General.... Along with my driverless highway idea. Of course real cars, motorcycles, girls, sports, college, family, Army all got in the way, and I gave up being an inventor, just inovating and improving what I have. I dont have any idea of the other project you did, but I'm intrigued! Will be watching this thread! Steve |
