Why Wind and Solar will never work

Excerpted:

* Solar technologies have improved greatly and will continue to become cheaper and more efficient. But the era of 10-fold gains is over. The physics boundary for silicon photovoltaic (PV) cells, the Shockley-Queisser Limit, is a maximum conversion of 34% of photons into electrons; the best commercial PV technology today exceeds 26%.

* Wind power technology has also improved greatly, but here, too, no 10-fold gains are left. The physics boundary for a wind turbine, the Betz Limit, is a maximum capture of 60% of kinetic energy in moving air; commercial turbines today exceed 40%.

* The annual output of Tesla’s Gigafactory, the world’s largest battery factory, could store three minutes’ worth of annual U.S. electricity demand. It would require 1,000 years of production to make enough batteries for two days’ worth of U.S. electricity demand. Meanwhile, 50–100 pounds of materials are mined, moved, and processed for every pound of battery produced.

2. Hug Hell, I could use a beer

Rode all the way from Massachusetts to Maryland

Dropping my Grandkids off at my Daughters house now

Then home!

8. Coming up your way in the next 2-3 days

I'm buying a vehicle at a dealership in Corry. It's a bilious shade of green, but otherwise fits my requirements.

Oh well, it's an excuse to stop at Sprague Farm Brewing. It's in my opinion one of the beat small breweries in the whole Northeast. I love the grounds. They have acres to roam.

3. We do not have the battery technology to store the excess power we need

every home would need a room where batteries keeping power for a month use would be stored.

Massive footprint required.

5. I was on a Nuke Ship, never felt unsafe

We used to joke about one day opening a scuttle and a 6ft Cockroach comes crawling out!
