I found something
very interesting on page 34 of the latest Popular Science magazine : Clarian Technologies
Clarian Technologies: Jellyfish Wind Appliance
is going to offer for sale ' next year ' a 3' vertical windmill that will power up 40 kWh of electricity a month, and just need to be plugged into an outlet to power the house.
Here's hoping that it is not vaporware.
Wow. Sounds too good to be true !
