Imagine developing a machine that is so simple in nature, yet so revolutionary to the modern world that it has the potential to increase the enjoyment of life and separate you from energy corporations with cash orientated agendas.
Cooking your own food and powering your own house from a stand alone system inside your garage, that requires little maintenance and has the potential to run for thousands of years! The potential benefit of having a closed loop, self-sustainable, economic and environmentally friendly free energy generator in your own house would be astronomical. Plus with the potential for this machine to run for thousands of years untouched, is the best physical legacy you could leave for future family members.
Now you are thinking that it is all too good to be true and that what you remember from high school physics is telling you that perpetual motion is impossible. These contraptions, however, work by having strong magnets that constantly repel the rotating ones, so a force is always being exerted, but it is limited only by the lifespan of a permanent magnet.
There are various, payed plans for such a contraption scattered all over the internet, such as the ones sold by Hojo Motor. However, the fact that these people are selling plans on how to build it yourself, and not building it themselves has very easy potential to raise eyebrows. It still is a potentially low risk investment, due to the money back guarantee they offer in the case that the plans cannot do as advertised.
