Portable Power Generator Circuit – The N-Machine
When this free energy generator called the N-Machine was developed by the famous physicist Bruce DePalma he could implement a 100 kilowatt generator right in his garage with ordinary tools. His machine could power his entire house electrical completely free of cost, forever. But sadly he could never use it since making such device or […]
Making a Time Machine – Concept Explored
Wondering how to travel in time? Learn it with great Sir Stephen Hawking, according to whom time warp may be an option but seems pretty impractical, the reason being the feed back loop which will just oppose the feasibility of making a time machine and the concept using this theory. Are you intrigued by the […]
