There’s a scientific project called “AirHES”. Briefly speaking, it could (theoretically) allow individuals (pretty much everyone) to run their own little electric stations to obtain cheap and green electricity (such power plants are claimed to be very effective, affordable and eco-friendly — i.e. no CO
2 emissions, etc). Besides electrical power, such plant would also provide clean drinking water, so it can be extremely desirable to have it in places where fresh water is a problem (according to Wikipedia, 780 million people in developing countries lack access to clean water). Such stations may be even built to be used as a mobile power (and water) source, which is a great opportunity for boats.
The invention is described in detail on it’s web site:
airhes.com.
In practice, the inventor still hasn’t raised any money to run all the necessary experiments to prove that everything works well (having the rest of the work done & building a test device would cost about 100k dollars). He’s in search of an investor, but so far he hasnt’t made a deal with anybody (seems like no one is willing to take the risk of possible failure, even though the gainings in case of success are extremely big).
