Re: [a-w-h] Space heating with savonius windmill?
- Hi JD,
I'm just up the road from you in the San Juan Islands, and have been
using wind energy for almost 20 years.
Get a copy of Paul Gipe's _Wind Power for Home and Business_. It's a
comprehensive treatment of the subject. Hugh Piggott's _Windpower
Workshop_ is an excellent treatment of homebuilt machines. Both are
available at http://www.picoturbine.com
Savonius rotors are not the best design for generating electricity.
No vertical axis design has ever been commercially successful.
Wind power for heating is certainly possible, but you'll need a large
machine, since heating is a large load.
Check out http://www.solarenergy.org for information on the renewable
energy workshops that I coordinate up here in October. I'm bringing
Hugh Piggott over from Scotland to teach a Build Your Own Wind
Next time you're driving north through Deception Pass, pause at one
of the gravel pull-outs east of Pass Lake on Highway 20. Look up on
the hill to the north of the lake and you'll see a wind turbine. It's
a direct drive Jacobs machine, and I was involved in the installation.
Wind power is great, but go in with your eyes open. Most homebuilt
machines fail or disappoint, and commercial machines take serious
attention and maintenance. Wind generators require tall towers--30
feet taller than anything within 500 feet is the rule of thumb.

do. This would require a very large structure. Check my home page
for a table showing the size of machine you need to produce a certain
number of kWh units of electricity. Heaters use a lot of kWh. Most
people with windpower systems only use heaters as 'dump loads for
surplus power after the battery is fully charged.

battery. Store the heat in a concrete floor, or a pile of bricks.
