"Tom, "My issue is that American Architecture is dumbed down to think you can be net-zero and not collect thermal energy, that's storing heat in winter, cold in summer at the right time of day or night." Perhaps you need to visit the…"

"According to the article the code standards did work but only enough to cover growth, not a net reduction. My issue is that American Architecture is dumbed down to think you can be net-zero and not collect thermal energy, that's storing heat in…"

"The energy that you can get from a wind turbine is proportional to the swept area.  If you can get ten times more energy from a small wind turbine by changes to the generator - then you could get ten times more energy from those massive wind…"

"Tom,  there is a significant efficiency loss when you look at the energy used with batteries on site by each windmill.  I'd fallen into that trap before and it just doesn't pan out.   In most cases you would be taking the AC…"

"Efficiency is notching up incrementally now and it's expense, yet, until buildings collect & store thermal energy it's not logical to think that usage won't go up on a grid with more people. If that power is distributed to at…"
