In the past few years, we have covered plenty of off-grid and emergency power generators here. The Pikasola Wind Turbine Generator Kit is also worth a look. It measures 23.8″ long and has a 3-phase permanent magnet synchronous motor and an aluminum alloy body.
This wind power generator is rated 400W. It can withstand winds up to 40 m/s and works in -40 to 80C temperatures. It comes with automatic wind direction adjustment.
