Check out what Google is backing - Enhanced Geothermal Systems

 

EGS: What is an Enhanced Geothermal System?

Geothermal PlantAn Enhanced Geothermal System (EGS) is an engineered subsurface heat exchanger designed to either extract geothermal energy under circumstances in which conventional geothermal production is uneconomic, or to improve and potentially expand the production operations so that they become more economic. Most commonly, EGS is needed in cases where the reservoir is hot but permeability is low. In such systems, permeability may be enhanced by inducing slippage along preexisting fractures (often called hydroshearing) or by hydraulic fracturing, using high-rate water injections, and/or chemical stimulation, or a combination of both. In some cases very little pressure is needed to cause a permeability increase, in others high pressure may be needed. It depends on the in-situ fracture patterns, stress magnitudes/orientations and rock strength. Once the permeability has been increased, production can be sustained by injecting water (supplemented as necessary from external sources) into injection wells and circulating water through the newly created permeability, where it is heated as it travels to the production wells. As the circulating water cools, the engineered fractures, induced seismicity, and chemical dissolution of minerals may also create new permeability, continually expanding the reservoir and exposing more heat to be mined.

Hi Mary:  For solar cooking - I bought a  'kids cocoon' chair  from Ikea once (it's round and parabolic shaped) for $4...  glued a $1 car sun shade reflector inside it and put a black 1 qt pan in the bottom... it boils water in about 20 minutes - in the summer time.  Solar cooking is a real niche area....  making your own as the books Samantha references and various internet links - like you tube and http://www.cookwiththesun.com/solar.htm  are plentiful.  Above all - have FUN!

This is wonderful information to have, particularly interested in that posted by Samantha as i am try to get info like this into our Community Center here for distribution to our small community of about 750 people.  Thanks everyone.

Lo-Cost DIY solar

I've discovered it costs 70%+  less $ to put in your own simple solar  HW or PV system without following the bureaucratic and corporate utility-driven CSI (California Solar initiative) rules.  The only catch is you need to provide your own labor or find somebody else to install it properly. 

 

Here's a couple examples from my presentations on lo-cost energy:

 

Lo-Cost DIY Solar Hot Water Drainback System

  • 2 Absorber Plates (wholesale- El Cajon) $530.//DC Variable pump (Hartnell)$180.// Reservoir tank$  50.//Copper Piping + Fittings $100.//∆T controller + Wiring.$140.//Misc (Framing, used Patio Door Glass $200.                                     
  •  ~TOTAL $1,200.// minus 30% Fed Tax Credit on equipment  $360.// 
  • ~ net total cost $840.

 Lo-Cost DIY  Solar PV Stand-alone System

  • 2 Collectors (270Watt) $750.//Controller $  56.// Inverter $860.//Battery (2) (optional) $290.//Monitor (optional).$140.//Wiring, shunt, Misc $200.
  • ~TOTAL$2,296.// minus 30% Fed Tax Credit on equipment $ 688.80.
  • ~ net total cost  $1,607.

Reduction of energy use is a closely related option, which, of course, may also be imposed (on more and more entities).  Here's information about an opportunity, called the Thousand Home Challenge, to contribute your perspectives on the process and its outcomes.

Thanks for the link - we are going to try to post it on the main page so that folks can easily find it. It falls under the 'primary resource' list for sure :-) Hmmm...maybe we will create a page on the main bar with that title....

Cheers!

While I was searching, lo and behold, I found a compendium of solar cooker plans here:

something for everyone here...great resource!
Comment by Samantha on October 7, 2010 at 1:38pm
I just realized some stuff is on another computer, so I'll have to crank it up and search. Meanwhile, I did find this in the list of recommended books from SEI. Prices may have changed, because it's a few years old, but then, check Amazon...

Hi everyone,

I'll dig up my directions and post. Thanks for responding.

Light and Peace,

S.

I'd love the info, too. I have a Sun Oven (made black beans in mine yesterday) and I use my car for a solar dryer... it works great in our dry, warm summers! A solar sauna sounds wonderful, too.
