In an email conversation with Connell, he stated that "a six-vane version with an efficient alternator should produce at least 135 watts of electricity in a 30 km/h wind, and 1.05 kilowatts at 60 km/h
Honestly I wouldn’t expect too much, one may be enough for light-use emergency power. 30 km/h wind is not something you see every day in most places, and 60 km/h sounds like the kind of day I would stay indoors.
If you live in a windy place, you could probably power your house lights with a couple of them, if you use LED lighting, but don’t expect to power an electric oven or heat your house with it unless you have a yard full of them.

Honestly, even lights would be good. I’ve been without power for up to 4 days several times, and lanterns/torches just don’t do enough.
Plus charging phones, keeping router+modem alive, and charging CPAP batteries would all be useful.
