Rooftop wind energy innovation claims 50% more energy than solar at same cost
> Aeromine said unlike conventional wind turbines that are noisy, visually intrusive, and dangerous to migratory birds, the patented system is motionless and virtually silent.I've been a supporter of wind energy for 30 years and it's my favorite generation source. I want to believe the claims of this company, but the above quote is activating my spidey senses. Conventional wind turbines are not a serious threat to birds. According to Homebrew Wind Power by Dan Bartmann and Dan Fink, here are the causes of bird fatalities per 10000 fatalities (page 28):  5500 Buildings / Windows
  1000 Cats
  1000 Other
  800 Power Lines
  700 Vehicles
  700 Pesticides
  250 Communication Towers
  <1 Wind Turbines

Many other sources agree.Any wind turbine company will know this. For one to spread this lie makes me doubt their other claims. I hope they're right about price per watt but I have serious doubts.That said, I would LOVE to have affordable grid-tied residential wind to complement my rooftop solar. It's not an easy problem to solve.
