Too bad you didn't trust the parts in the middle. That's my experience I am imparting. Take it or leave it at your peril. What I am imparting is also a warning. Example, my brother is as conservative as it gets. He was going to buy a $200k diesel motorhome. Since I explained what was going to happen in the "future", he decided against the huge stranded asset. He even put solar on the roof to run his air conditioning (San Diego Country Estates). He is renting the occasional motorhome and hoping technology from Eindhoven will trickle down to the rest of us. solarteameindhoven.nl These guys and girls, engineering students, made a 5 passenger solar car with a trunk that can go 1,200 miles on a charge over two days of sunlight. They made an RV and now an off-road vehicle. These guys give me hope and are making things more interesting than flashlights. Now that's hard to believe.BTW their car is so efficient it does 45mph in sunlight without the battery, infinitely... that's why you need a battery to buffer/save energy. The sun don't shine at night. That's why you need a mix of renewables.
