As for the maths, it boils down to: Ion wind contributed thrust in grams = 0.5*i*d with i in mA and d in mm Is this simple enough for you? > I'm basing the statement on > something I read about a NASA (Nasa Ain't a Space Agency, or Not A Space > Agency) mathematician, I believe it was saying that ion wind was not > sufficient to account for the thrust, and honestly when you look at the > different things that have been done to reduce or apparently rule out ion > wind, well they paint a far more convincing picture, especially since as I > said ion wind doesn't account for other embodiments of Brown's work hardly > at all.

How cute, is this what you tried to fly your lifter with? :) You can get what my friend Xavier (fka Saviour) from Blazelabs described from the 1kW multi-flyback shown on his site (a supply I know quite well :). > Honestly you seem to know very little about electricity in theory or > practice. lol :) Michel
