One of Tesla's inventions that has gone relatively unnoticed is the ionocraft. This was one of Tesla's dreams: to create flight without the use of jets or moving parts. The ionocraft, hence the name, ionizes the air to create propulsion. This simple craft to the right can hover a few inches above the ground with an external power source. If the technology is perfected, which can easily be done, we could very well reinvent air transportation.
