Consumer solar has been a game changer, so doing the same for wind would be a huge innovation. But the reasons everyone doesn't already have wind generators on their roof is it's a much harder problem to solve. Not least of which is wind speeds are significantly lower closer to the ground. So I expect their 1kw output has a very narrow "optimal conditions" window. This might work if you live in a desert? Though given enough time with climate change...

Yes. The power in wind is proportional to the cube of wind speed - which falls significantly as you get closer to the ground especially in a typical residential setting. Anything below 15m is going to struggle to deliver any kind of useful power.

And wind turbine power scales with the square of the blade length. Which is why turbine blade designs have completely displaced this sort of "wind catching surface" device which scales linearly at best in terms of materials. Solar PV scales linearly which is what makes small and domestic PV practical.

The advances in wind power over the last decade or so have come from engineering bigger and bigger blades.

I don't see domestic wind power ever being practical at all but especially given the competition of solar PV even far from the equator.
