I visited Louise Bourke in 1980 and bought one of the few autographed and colorized copies of his book. She had arthritis so bad she could hardly walk, but was still quite spry in the mind. Quite a character!

She lent me his original production notes on the engine, which I copied and returned, and showed me photos of him and his engines. She had a lot to say about the "taking" of his engine by his "partners" in the venture. It was quite a story of greed and corruption. This was just before or just after Pearl Harbor, as I recall.

I have contacted various interested individuals over the years who have built one of his engines, and always asked what fuel they were using. Regular mo-gas was always the answer to which I responded with the formula he developed. It's not in his book, so no one had heard of it. No one it seemed could get an engine to run in the hydrogen-oxygen cycle like he did.
