I would also investigate Radiant Barrier by Innovative Insulation in Texas,  
and Geobond in Kansas City.

  I had the same vision, and looked into alternative building materials--Rastra 
block (cement that is poured into foam molds, with rebar inside--great to cut 
heating and cooling costs), hay bale house (cheap, with the feel of adobe, but 
beware of rats and mold if not done right), underground house (do this right or 
you'll have problems similar to those in a basement).

  I ended up doing standard but beefed up construction--4 X 6 wood, with 
plywood covering inside and out, roof tiles nailed down, roof bolted to walls, 
walls bolted to foundation--the same requirements as for hospitals and schools. 
 We have our own well, our own solar power (partial only, as it is still 
expensive, even with a government-supported rebate).  

  The hay bale idea sounded great, but I live in earthquake country.  Rastra 
was too expensive, and too difficult to make changes in electrical wiring once 
it is up.  With R-19 insulation in the 4 X 6 walls, though, we rarely use air 
conditioning or heating (except for wood burning and pellet stoves).  Also, 
dual pane window glass, with gas inside, cuts down on heating and air 
conditioning costs, as do appropriate window coverings.

  Don't underestimate the difficulty of getting anything unusual OK'd by the 
planning department, unless you are planning to build without a permit. Also, 
if you do anything out of the ordinary, you may have to do it yourself, as it 
is hard to find someone to do anything but the usual standard stuff.

  P.S.  It turned out WONDERFULLY, but what an undertaking!  I would only have 
energy for this sort of effort once in a lifetime, though.
