About
This is a machine that transfers heat and water vapor between clean, outdoor air, and polluted, indoor air. It allows us to bring in clean air during very hot or cold weather while keeping heat ingress or escape very low.
Impact
The world needs clean indoor air, lots of it. It affects sleep, cognition, many many diseases, all kinds of stuff. Energy is also a big deal, we want independence and saving energy helps a lot with that.
Progress
I have made many good working prototypes. I have proven that sensible efficiency is very good, and found a way to produce good heat exchangers, coated with silica gel, even. I've proven it's quiet and powerful.
Team
Well, I got this far :). It's pretty close to being done.

The original page also broke each season down by fund drive and showed an Available (unclaimed) balance; that level of detail survives only on the preserved snapshots.
