People still watch YouTube at 1x speed?


I find it necessary to listen to 33 rpm records at 45 rpm due to my superior mental processing.

That is a reference to this, which I read twenty years ago, but somehow remember better than anything an instructor ever told me.

By the way, Gus from "Psych" was killed in "Holes" Shawn Spencer did not solve that one, it was Shia LeBeowulf.

China domestic oil production peaked this year. Their demand is projected to keep increasing to over 3X domestic supply. To a total of the entire world's available exports.

Depending on whether you're flying east-west,or north-south,there are established flight rules pilots must follow in order to maintain safe separation distances.You fly at odd or even altitudes above ground level.I think 500-feet is the minimum vertical separation.
There are classifications for different flight spaces,like Class-A,Class-B,Military,etc..
The FAA is trying to prevent mid-air collisions,as well as protect planes from wingtip vortices,which can send light aircraft into the ground.

Maybe they're Photoshopped.

All of it? That explains a lot.

BTW, #34 is wrong.

I found the Zenith system (1000x suns in a multi junction cell) it's only 22%. That's why they bankrupted... The cell could be 45% efficient, but it probably don't get so much due the temperature it works, since it need to keep water hot, and so thye cell, reducing cell efficience to electric energy.

I still would like tho see a system of concentrated photovoltaics, that split the ligh spectrum, sending the infrared light to heat water and the other wavelenghts to multi junction cells.

There is a campaign claiming that Arizona is so sunny we should produce more solar power than any other state. I think AZ is ranked third nationwide. I spent hours and hours researching this law they are trying to pass and finally decided to fulfill some of my adult responsibilities, although I probably watched cat videos instead.

Arizona may have more sun than any other state, I tried to find out for sure, but it does not seem that anyone has tried to compare entire states.

In alphabetic order (hopefully):

Please note that the colors used for each state do not correlate with other states. Sunny states and dim states use the same colors, so you need to look closer.



















Arizona ranges from 6.3 – 8.3 kWh/m²/Day and honestly every range seems approximately evenly distributed. Call it 7.3?

California goes from 4 – 8.5 and Imperial Valley is sunnier than anywhere else in the United States. It looks like the vast majority of California ranges from 5.8 – 8.5. Ignore Eureka and say the state averages 7.15? The state is far larger than Arizona with far too many people. I do not see any reason for California to not try to meet their power needs with solar and they have four or five times as many people as Arizona.
I argue that California should produce the most solar energy.
It does.

Florida varies from 4.7 – 6.0, but mostly looks 4.7 – 5.5. 5.1?
Nevada: 5.0 – 8.5. Maybe 6.8?
New England: 3.3 – 4.5. 3.9?
New Jersey: 4.0 – 4.5. 4.3?
North Carolina surprisingly produces more solar energy than Arizona: 4.2 – 4.9. 4.6?
Texas: 4.5 – 8.0: 6.3?
Utah: 3.0 – 7.5: 6.15?

Yes, the Southwest has abundant sunlight, but do you know what else we have in plentiful supply?

Dust and heat.

Neither of those are good for solar power.

“Photovoltaic modules are tested at a temperature of 25 degrees C (STC) – about 77 degrees F., and depending on their installed location, heat can reduce output efficiency by 10-25%.” https://www.civicsolar.com/support/i...l-efficiencies

Mark Rober asked some kids and they installed sprinklers on their solar cells in California, which he put on a timer, and runs once a week: https://www.youtube.com/watch?time_c...&v=a1D-fZP8qJk

Sounds like you need a state where they get tons of sun but not incredible temperatures all the time across the whole state, maybe some where like new Mexico.
