Your Challenge:
Create a perpetual machine people can buy with less than $400 that produce free electricity that can power the entire home 24 hours a day, 7 days a week. Of course, the machine would have to have an output to plug into the home's grid box. Or, an output to plug in surge protectors.
So, basically we are supposed to create a cheap machine that creates infinite amounts of energy? This would destroy the whole energy market worldwide. It would be a good thing, of course, but I guess many people would first go and sell as much energy as they can. Maybe companies would start installing those machines in power plants and have giant profits!!!
