</div>I disagree very much. For most people on this list PV is<br>
is a very affordable way to shave off the bulk of your<br>
electricity bill, or to allow you to live off-grid, which<br>
vastly enhances your exit options. Bootstrap is a process<br>
that profits from economies of scale. Why is solar so<br>
expensive in the sunny US versus the low-flux Germany?<br>
Because it takes a decade to build the market.<br>

</div>I would be looking into geopolymers, and in just low-embedded-energy<br>
structures in general. You have to crunch the numbers whether a steel<br>
frame house with glass foam/carbon insulation is going to ROI over a<br>
cob construction, or some advanced low-tech things I've seen on a<br>
certain subreddit.<br></blockquote><div><br></div><div>I think it's a reasonable area of research to figure out how to use atmospheric CO2 to build walls and stuff. I'll leave it at that.</div><div><br></div><div>
