The European personal wind mill with compact blades like a push lawn mower is called the "Turby". Price ~$12,000 plus batteries.
It could pay for itself inside of 3 years but it would take 3 of them to make a large home entirely self sufficient.

It will not enter the US market for at least 3 years.

No moans about it - its a good idea and so small that I forsee an age similar to the time when TV antennas bristled from every roof top.
