1kw per square meter is the theoretical maximum. A car driving down the highway, not accelerating consumes 50kw+, and that goes higher at higher speeds.
The conversation drifted into solar when I don’t believe anyone has proposed a solar electric passenger “jet,” but rather an electric one.
That aside, the fact remains that 42 foot motorhomes exist, wherein all “house” functions including air conditioning, heat, hot water, stove, microwave, refrigerator, multiple large screen LED televisions and computers are powered by solar alone, from panels installed upon the roof of the motorhome.
I’d love to have one, and have been researching it extensively due to having a classic old GMC motorhome basically fall into my lap very cheaply. As budget permits I’ll be switching to Danhard air conditioning, compressor refrigerator, etcetera in order to keep the power draw as low as possible and I’ll be putting about 1600 watts of solar panels on the roof. The GMC is challenging in that regard because of the (in my opinion beautiful) styling of it, more “fuselage” with no flat roof. But, with the Danhard type A/C the roof will be cleared of obstacles. I plan on a styled, enclosed “rack” system that deploys when camping, mimicking the visual mass of the A/C units and storage pod. That’ll keep it from getting ugly up there.
