The end game is to be carbon neural ( CO2 from panel manufacturing +concrete+construction – generated power CO2 offset ). Solar panels are very costly in terms of CO2 to manufacture, they are marginally carbon neutral. Concrete generates vast amounts of CO2 ! If used in a residential setup via a grid tie inverter they can be favorable, however if batteries are incorporated it is a financial and environmental disaster. Environmentalists need to get their heads out of their asses and smell the roses . The rest of the people just need the rarest of assets…. common sense.

Solar oceans are the way to go, do the math!

So the road would payback itself in 30 yearsinstead of 15. I wonder what 30 years of wear loojs like lmao

Great approach. IMHO you are going a bit wrong from about 11.00 min: it has to be 26400Wh/day, resulting in 70m2 (you mention that), and the practically used surface is 70-1,75=131m2, roughly double the amount needed for powering 3 houses. So the payback time (joke, of course) should be calculated using this figure instead of the 70m2 you are using, resulting in a mere 775 years.

You did not account for losses due to traffic and/or idiots blocking the sun.

There are plenty of rooftops that are unused that would probably equate to as much (or More surface area) than using roadways.

Thanks for the pay back calculations and mentioning that it would take 1500 years to pay back – and pointing out that it was a R&D effort. Lets assume that it is order of magnitude for a take up. the it would have to last 150y. In my experience 15-25 y is respected return and that is 2 orders of magnitude. You also neglected a return on alternative investment for the same amount of R&D Cash a problem I experienced in CSIRO. It looks something like this: "If you invested the same amount in cash market you would get a better return on your investment"what BS. If most of us practical R&D people got up in morning and thought like that we would never get up to do R&D.

Good work !!! I been telling people for years. But your Blog does it well
PS I like your HP41CVX, had one after HP19c I sold it to buy HP75c. but then settled on HP11C still have it.
Keep up the good work I like your calling BS its done with a style.

I don't know why'd even want it to work. You'd still be increasing the risk and consequences of accidents.

100% renewable energy is 100% bullshit. Why don't we stop throwing money at these things and invest it something that works the same or better than fossil fuels? Here's a fact that you won't see on the news, manufacturing wind turbines releases more carbon in the atmosphere than they actually save during the entire life cycle of the fucking wing turbine! These pipe dreams cannot change the laws of physics.
