5KW seem's too good to be true, UK has an average windspeed of somewhere in the region of 3.5 m/s and the amount of kinetic energy in the volume of air it interacts with seems way less than what is promised, especially if Betz Law comes into play. For example, I've been tinkering with the idea of a low friction induction method and it can only generate about 4 volts at 0.2 amps and its about the size of a lamp shade, very efficient system but just not alot of energy that can be generated due to the low wind speeds of the UK. I expect this'll be in the region of 500watts at average UK windspeeds, which isn't nothing, but it isn't 5KW. 5KW is enough to power any house, even one thats using a hot tub, which takes approx 3KW, just not a reasonable expectation from something that size.

There have been several attempts in creating neat "home" wind systems that do not involve huge windturbine wheels, none have succeeded as yet, we'll just have to wait and see. in any case for me this would be a supplement to my solar panels. it will all come down to size and cost per kWp in the end.

You should check out Darwin wind turbines, they are omnidirectional and take advantage of increase the pressure to increase speed.

Almost as good as solar roadways.
