Say goodbye to your solar panels – 1500 kWh of electricity with the first silent wind turbine for home

1. Suuuuuuure it does – sure it does.

2. No thanks! I rather keep my photovoltaic panels.
   Go and wreck your own roof with that plastic toy.
   Edit: I didn’t wan’t to sound rude, those companies are like snake oil sellers from the wild west. The engines won’t harvest anything,too small, you need height, and you need diameter/wind collecting aperture/area.
   And you certainly don”t want to rock your house to shambles by screwing a wind-driven rotor on top of it (vibration and more).
   And wind speed – who has constant good wind speed?

3. Lol. I would prefer an efficient aerodynamic design

4. Small wind turbines don’t work great.

   Theoretical power after dealing with installation and maintenance and actual performance with real
   Wind, just don’t pencil out most of the time.

   Maybe is a REALLY consistently windy, not too sunny, rural location they can work, but I don’t see this as the masses leaving solar for turbines.

   They just aren’t that good in mini-scale.

5. Just stop these reoccuring fake stories.

   There is not, and never will be an efficient home wind turbine. It’s just physics: turbine power goes with the square of the cross section of wind capture and third power of wind speed. Bit bgger&higher -> 10x the output.

   Therefore, a large shared turbine will always be massively more cost-efficient than anything in your garden.

   Furthermore, big boring turbines are remarkably close to Betz-efficient, so there is *no* innovation that will *ever* reverse the gain from scale “by using this new more efficient quirky design” as these stories always claim.

   That people who say their job is something-something-green power keep sharing these scams and dont get the simple physics behind their field is highly worrying.

6. Bullshit, wind turbines don’t scale down and need high winds for a good capacity factor.
