The main hurtle to get over with wireless energy is the extreme loss of energy. Very inefficient to date.

That means you have to beef up the airframe and probable wing area. Now the aircraft is even heavier. Batteries are going to need to get vastly better before it becomes a reality.
Yep.... Two people and baggage = 3100#

I would hope when Van's goes electric, they fly a RV6 solo with FP prop and very low on fuel and make that the mark for the handling characteristics of the RVE17A

I forgot about actually carrying a payload!

Default Electric power

I have a simple question to GDRudolf….no fossil fuel?? Where do you think electricity comes from? Oh yes, either fossil fuels or perhaps nuclear. But there again the conversion from fossil to electricity is very inefficient compared with a good recip

It is too bad that N. Tesla was not allowed to complete his research and the large scale test. That set us back almost 100 years.

It is an interesting story, though. Dig into it and you will likely find that the blossoming big oil companies were terrified at what a successful test would mean...

Default Tesla Electric powered RV

I recently finished reading N. Tesla's autobiography "My Inventions", and his biography by M. Cheney "Tesla Man Out of Time". It seems to me N. Tesla was as much a promotor and sensationalist as he was a technologist. I suspect that the "wireless energy" invention was not efficient enough to be practical and that there were laws of physics that couldn't be broken.
