The climate change consensus extends beyond climate scientists

I too support cellular solar power.
But to go totally off the big grid you need batteries, but the cost of the batteries and their replacement makes it cost prohibitive.

There are a fee ways to position panels.
Fixed panels, passive tracking and live tracking.

Fixed panels, obviously bolt them to something that doesn't ever move.
Passive tracking, seasonal tracking what ever you want to call it usually moves panels on a single axis to take advantage of the higher and lower sun as the seasons change, can be manual, require tools to loosen nuts and bolts to allow for movement or be somewhat automated.
Then live tracking follows the sun on one or more axis throughout the day. Your east west tilt is usually all automated, the north south tilt may be fixed or manually moved, or automated.

Not if John Goodenough battery, solid state, can really work, even than not so fantastic as he said for energy density, since they managed to create a solid state battery using sodium and workable at fine temperatures and lasting dozen times more charge cycles.

I imagine in 20 years a lot of solar cars, using such batteries, and many homes with solar panels, all connected in grid.

Battery don't need to have the same energy densit of gasoline. Anyway the gasoline have 1/3 of the energy reported, since the reported value it's for the bunring it with oxigen, and the gasoline itself only have 1/3 of the energy of this combination of gasoline and oxigen.
Second the electric motor it's much more efficiente (up to 98%) than combustion engine of cars (about 25%).

The city of Domes, in Logan's Run fictional fantasy, had a solution, killing people before they get old. This would avoit about colapse of the system, reduce costs, avoit dirty diapers and need of caretakers.

Also avoid back pain, reduce incidence of cellulits in women, prevents skin premature agging.

We could also reduce the incidence of non-blue eyes and non-blonde hair. Why stop there!

I'm against suicide in principle, but am for the freedom to end your life if you consciously, deliberately, and voluntarily do so.

People have intrinsic value that extend beyond their ability to contribute economically. Better to carefully engineer genes that create the biggest problems for humanity than to eliminate the burdensome people. After all, 100% of us are burdensome at some point.

Regarding population; it isn't clear to me that the planet cannot hold this large population. All measures of well-being have gone up for humanity despite the growing population.

That isn't to say our numbers aren't without problems, or that it's necessarily good, but we're as well off as ever. The population is likely to decrease via less disastrous ways than those that loom ominously in our imagination.

Hey, have you ever heard about comic sarcasm???
You took my sarcastic post literally.

The focus for the last 40 years has been to cram more power into a smaller space and try and do it cheapy.
Electric cars renewed that push and added the need for good performance over a really wide temperature range and to cram even more power into a tighter space and do it it without breaking the bank.
The market for really cheap cost per kwh batteries that last a really long time is only about 10 years old.

Hey, I wanted to return the favor! It's all about reciprocal exchange.

According a battery researcher, they need something like a battery 5 times cheaper and with 5 times the energy capability than lithium cell phone batteries.

They said it somewhere in this documentary :

Colonize the oceans. It's energetically cheaper than going to space. Just getting rid of real estate mortgages will remove friction from the system.

Nope.
At 5x current technology you are effectively burning aluminum in air.
Which is the most energy dense chemical combo that can realistically be accomplished.
The only one that might be more energy dense is oxygen iodine, like for a laser weapons system.

I mentioned the article freebird shared to a friend and he responded "Batteries FTW."

FTW must mean something different than I thought--and so must his PhD.

I was not going to say "This knowledgeable-sounding guy in my forums," so I looked for a source to support Oil Pan:

It can cost $15,000 to install solar panels on a house and enough batteries to run the air conditioner for three hours would cost another $15,000. The RoI on solar is about eight years, the warranty is ten, and a full battery array would not pay for itself until six years after the warranty expires.
