Hornet wind turbine next door

After the storm destroyed the Ampair 100 that was on this mast, a neighbour bought a Hornet from http://windgenerator.org.uk/  This is the 8-blade 1250 watt version.  Apparently it has been seen producing 1251 watts into a 24 volt battery “in the bottom of a valley”.  Which I assume would be about 40 amps and 30 volts.  However this is one on Scoraig is connected to a 12-volt system.

The Hornets are made by Hydrogenappliances in the USA and are a bit similar to the products of Missouri Wind and Solar (see below).  Converted car alternators and tiny composite blades.  The 28″ long blades look like copies of the AIR machine’s high speed blades but on the Hornet the alternator is stiff to turn so they use them in large numbers to get enough torque to spin in low winds, and this somewhat defeats the low solidity.  Furthermore they recommend cutting this tips off to get more power (?)

Having said all of that it’s an affordable little unit and when I went to look at it in a good stiff breeze it was purring along producing a respectable 50-100 watt output.  Let’s see how long it lasts.

I live off-grid in NW Scotland and have spent my life playing with wind turbines. I also love small hydros. Hands on renewable energy is my thing and I like to learn and to share my experiences.
