Hello world. Is there any way to convert mechanical energy into DC electricity energy WITHOUT using any magnets ? I know there is homopolar generator but it uses magnet and as I said I need something that doesn't use any magnets. I also know there are stuff that use friction (triboelectric effect), but they are very inefficient and waste a lot of mechanical energy input into heat. I need something fairly efficient, for example at least around 75%, you know what I mean. Also please don't say that I can do that by using self exciting ac generator then using rectifier to make it dc, I need direct DC generation. Any ideas ? *_*
