Take Mike Oehler’s ideas and mix in a lot less processed material along with a lot of additional thermal mass and ya got this. Take a look, tis certainly worth the time. Gonna have to rethink a LOT of the stuff I have been planning. Didn’t get the Oehler video’s links from here but they are by Paul Wheaton who’s site the above link takes you to and are also on the page it takes you to. Some of this may take a bit to digest but I’ve had a bunch of stuff fall into place just reading this through one time. GOOD STUFF!
