Yep. I spent my own $40k (it is huge sum for Ukraine) trying to implement #1 and #2 with some success, but found that nobody really interested in saving of our planet, even when it cheaper and provides better comfort. Western engineers have some interest for my solutions, but nobody else (which is expected, because I'm the engineer too). For example, climate battery is a very simple thing. In our climate, temperature of earth at depth of 2m is 7°C all year round for $0. By additional insulation and insolation, this temperature can be raised to 20-20°C, to have comfortable temperature in a house all year round for $0. Nobody interested in that, because nobody will buy a house without a powerful heating system. #3 and #4 are easy to implement too, but my English is too weak to explain it properly. #3 is like e-bike on zip line (google "bike zip"), but with 4 lines for additional safety and comfort. #4 is like a giant sink with generator installed at top of a drain.
