Rakarskiy hi!
I have been following David's threads (Turion), about 3 or 4 by now, from very long time. The 'three battery system' and lately i have tried a similar generator like he does, but have not succeeded yet. I saw you sell a book with info for a flywheel with generator. I want to know is this all in russian or do you have an english edition. Actually i am from Greece but i understand english. I think you also have some program that you put parameters. Is that all in russian? Thank you in advance.
