As much as we prefer a good old-fashioned bird-killin' three blade wind turbine
, apparently they cause a bit too much vibration and disturbance for regular home use. That's where the Energy Ball comes in, with its spherical shape that captures wind less obtrusively and yet more efficiently. At least that's what we're told, we're a bit short on details. We do know that it's in the prototype stages and was designed by Swedish company Home Energy, who claims their smallest Energy Ball can provide about 15% of the necessary energy to power the average Swedish home.
