Ion Drives...
There was a show on discovery a couple of weeks ago regarding alternative methods to run engines and new science. There was a NASA scientist who argued that the ion drives used in space should work inside the atmosphere as well but that was about the only thing they said about it.
Does anyone know anything more about this?
There was also some type of shield of ionized air or something similar (dont remember to well the details). This shield would decreased drag by a huge factor and in that way decrease fuel consumption by a very huge factor. This had in fact already been tested at a NASA JPL lab...
