Main Question or Discussion Point
I'd trying to design a vertical lift engine to lift about 30 pounds in the air about one foot off the ground with minimum power. The device has to hover. The engine should itself weight 5 pounds or less and have a footprint no larger than one square foot. By minimum power, I mean something like 1-3 KW. I'm not asking for specific ideas (I've got about a dozen) but just if folks think it's going to be possible or not and why. Thanks.
