Announced back in October, the Swift Rooftop Energy System is another turbine which claims to be dead quiet (though I’m not sure less than 35 decibels is really ‘dead quiet’). Made in Michigan by Cascade Engineering, the Swift is rated at 1.5 kW and has a blade diameter of 7 feet. Like many of these, it’s pretty slick looking too.

That’s all good news; the less good news is that the estimate cost to install one of these is in the $10,000-12,000 range—which means that given current energy prices Swift’s maker’s prediction that you can pay this off in three years is, well, optimistic.
