One of Nikola Tesla’s most advanced technologies was his free energy electro-magnetic generator. He built a prototype in Colorado Springs and demonstrated it to JP Morgan, who promptly stole his idea and claimed credit for it. The prototype was destroyed by an earthquake, so nobody knows how well it actually worked. However, some experts claim that Tesla’s ether technology is more efficient than modern generators; they also say that modern energy companies do not want you to know about it because they would lose money if people started using free energy magnetic generators at home instead of buying electricity from power companies. Whatever happened to Tesla’s generator is irrelevant, however: according to some experts, these devices are still being developed today and may soon hit mass markets.
