I’ve been reading about these innovations for 30 years. When does the application arrive that is cost effective without the government subsidy? I’ve two wood stoves in my home plus a small wood/coal version in the basement because they are economical given my circumstances. When do we see this technology make sense economically?
They're already here, depending on the application.
Solar powered calculators have been around for decades. Solar powered emergency phones along the highways have been around for a number of years. Using solar power to charge batteries for evening lights for driveway paths have been around for a few years and they're getting better.
With each new increment in efficiency and decrement in price, solar becomes cost effective in more and more applications. Solar powered homes in the North will be the last.
It is far easier, and quicker, than you can imagine.
The first step is to regulate your use of the wood stoves, essentially making it a crime for you to heat your home with the ordinary. Then, punish coal companies and stop the construction of coal fired power plants.
There, project complete, it now makes sense to use this technology if you want to live in a warm home.
