#Steam generation has ... issues.

You keep it in a pressurized container it has a lot of potential energy.

If that vessel lets go, it makes a mighty big explosion.

It also has the fun of doing a phase change. Gas to Liquid. Much more #energy is release than just compressed air in the same volume at the same pressure.

This is why I would prefer to tinker with #solar #electric and #wind.

A #VAWT is probably safer all round; https://en.wikipedia.org/wiki/Vertical-axis_wind_turbine

Reportage SWR 2013 von Ingolf Baur: Vom Militär bezahlt, forscht die Uni Caltech in Pasadena/Kalifornien — bekannt aus der TV-Serie 'Big Bang Theory', an #Windkraft

Vertikale #Windturbinen #VAWT profitieren davon, wenn sie in Fischschwarm-Formation betrieben werden ➡️ sehr enge Aufstellung mgl — sich ablösende Wirbel verpuffen nicht, sondern werden von Nachbarturbinen aufgenommen.

I made a whole post on tumblr about the #VAWT #windpower #energyindependence idea I mused about on here a while back. Reblogs and boosts would be very appreciated, I really hope this can become a real thing!

We are planning to make (and replicate) standard installation, including one full-size #VAWT, #generator with battery, controller with extra load (water heater) and monitoring unit (arduino based, connected online to a public website, providing #wind speed, #turbine rpm/vibrations and V/A values from the generator circuit).

Now, the turbine part and monitoring part we have covered. The generation unit leaves some questions and I need your wisdom to answer them:

We are going to build several copies of this installation across Europe (see https://cnicoop.wordpress.com/2018/03/18/wind-power-to-the-people/ for details) and use it as a reference generator for other types of VAWT as well. So what we need is something long-term available, preferably in Europe, not too expensive (up to 50-75 Euro, perhaps) and standardized enough. Ideally low-rpm, so we can use low-ratio transmission. Up to 1000W AC or DC.
