Free Energy will change the World - Free Energy will stop Climate Change - Free Energy will give us hope
and we will not surrender until free energy will be enabled all over the world, to power planes, cars, ships and trains.
Free energy will help the poor to become independent of needing expensive fuels.
So all in all Free energy will bring far more peace to the world than any other invention has already brought to the world.

That is really amazing!  That new craft should really fly out there.  Very interesting reading.

Well, they rounded some edges, and did good to the sponsors, but they also added roughly 50lb acording to Spork. I am not sure the amount of drag previously generated at ~30mph apparent headwind amounted to all that much, in comparison to the power extracted from the wind with that, what, 12 foot propellor? It may help a couple mph on a good long run. And the weight might aid in being more stable in apparent headwind bursts.

The unpimped cart already performed above anyone's expectations, I suppose, being so basic. One rotor, no aero body work.

Thanks for keeping us posted!
This still "pains the brain" for me!

Seems like other techs could "evolve" from here?

Oh I'm just an intrigued groupie, reading all I sensibly can on the subject. Understanding, I do far from all.
I can totally see alternative prop setups be even more efficient. Boats can use principle too.
But in terms of practicality, it doesn't do much more than offer a (small) auxiliary power source on existing vehicles. You're rolling down a highway, GPS system knows the way. Wind sensors know what's going on. In appropriate moments, the will come from out of it's casing (like a double roof), and via a clutch to the drive shaft, be brought up to desired speed by, effectively, the wheels or engine. It would not do much, but when guided by a smart computer, it could reduce fuel consumption some. And hey, a prop on your car makes all kinds of sense anyway. It only rides 1 hour per day on average, the rest it's standing in the wind.
We need to harness all the free energy we can. If you see a car, or a building without turbine, energy is being wasted right there.
