I saw a farmer in his late 70's interviewed on the news in the late 80's, he has his house on solar power, he had batteries in a section of his barn for storing power for when there isn't sufficient sun to produce it. He had tanks for storing the hydrogen given off from the charging batteries, he conberted his 82 F-150 to run off of it, looked like a LPG kit. When you think about all the gas hikes we've been plauged with over the years, this guy sure had the right idea, wish I had known him, sure could have learned a lot.
