The article states that airflow is an issue, and you definitely need to control it and ensure fresh air is coming in. The heat exchanger, which passes outside and inside air, is one of the more expensive parts, but supposedly it works with 90% efficiency. Not sure how that's measured, but I've seen multiple articles since that first one where people are working on this.
I do think that passive solar, better insulation, some smarter techniques can work, but they need to be tested, deployed, and then regulated. That last part is the only way to reduce global energy. Individuals tend to do what's best for them, not the group.
I hear the complaint about taxes, but part of the tax credit purpose is to spur changes and innovations, not subsidize for everyone forever. This does get abused at times, but government can help move some of these technologies forward with a boost, and then remove the subsidies. That last part can be a problem, look at how many oil and gas still get.
Still I like the idea.
More and more as I research things, I'm not sure homeowner generation makes sense for wind. I'm not sure, but if you are trying to run a normal house, it seems to have a payback that's too high. However neighborhoods, or commercial properties might make more sense.
