mythbusters are a bunch of idiots pretending to do science , or worst they are payed by the same guys telling you that free energy doesnt exist while they run on it every day .
it is nothing to do with ion wind and nothing to do with heat or other crap ideas , its a gravity well that opens infront of the positive charge of the device , its very easy to do and as simple as that , you can also read the book of Paul de la violette to get the details witch i am reading now , well after the 1st , cant really read here in Barcelona , to many things to do ^^
go to alienscientist youtube channel and learn about it , and watch all of his videos and favorites , its like reading the encyclopedia that no one has told you about .
