Many ideas are out there in use but not recognised. We like complications or money and power gets in the way... There is a story of the car working on water and the inventor dying mysteriously... petroleum has too many things wrapped up in it and such. We need to look at the whole picture to include solutions for pollution and harmful effects so we can enjoy progress sensibly and maintain simple, existing systems that are fine as they are. I trust God, only He is good and He takes care of me.
