[Announce] Build a window box solar heater October 13th

[Robert Waldrop]

 Every year in the middle of winter I get worried 
about how low income people will pay their heating 
bills, and I always think about building window 
box solar heaters.  But this is typically too late 
in the winter to do anything about building them 
for that winter.  So I decided to get ahead of 
myself a bit.

On October 13th, I am getting together with Bruce 
Johnson of the Homestead School and we are going 
to build a thermosiphon window box solar heater, 
similar to the one described at this url 
http://www.jrwhipple.com/sr/solheater.html .

 Our purposes are to learn how to build one of 
these heaters and then see if it works well enough 
to make a difference in heating a home. By 
building one, we will also get some ideas about 
how to scale up production to make several.   If 
it turns out these little units produce enough 
heat to be useful in the winter, in November you 
will probably hear about a work day or two to 
build a bunch of these for low income people.  (I 
will also be doing fundraising to get money to buy 
the materials.)

 If you would like to join us, meet us at 9 AM on 
October 13th, at the Dorothy Day Center, 4909 N 
State Street in Oklahoma City.

 Note that this is not a workshop where we will 
describe to you something we have already done, 
but rather an opportunity for us to learn together 
how to do this kind of project.  If you need more 
information, email me at bwaldrop at cox.net .  I'd 
also like RSVP's if possible so I know how much 
food to bring.  (Yes, a secondary benefit of 
attending the workshop is some of my home 
cookin'.)
