A lot of the green energy ideas around today are based on simple ideas and ways of using stuff we already have because lets face it the global world powers will not easily just give up their huge profit by dumping oil and replacing it with something else.
Here the villagers of India take something simple and use it to their advantage. There are so many of these ideas coming out in the world at the moment, but they are not seen in the news or media because it does not involve some blood or politics. People need help and if their are not going to get it the Lord will provide wisdom for them to find the help they need.
