What powered the Rover 50 years ago?

Was itt batteries? Was it all electric? Just curious. Were the space suits climate controlled. Being the surface temp is about 250 degree fahrenheit. How did the wires and tires not burn?

Google is your friend.

They consisted of a spun aluminum hub and a 32-inch-diameter (81 cm), 9-inch-wide (23 cm) tire made of zinc-coated woven 0.033-inch-diameter (0.84 mm) steel strands attached to the rim. Titanium chevrons covered 50% of the contact area to provide traction. Inside the tire was a 25.5-inch-diameter (65 cm) titanium bump stop frame to protect the hub.

How did i not know this? I would have guessed it is generally colder than earth

Long before NASA existed, astronomers were measuring "obscure rays" (infrared radiation) from the Moon.
1846: Italian physicist Macedonio Melloni used a rock-salt lens and a thermopile to detect the Moon's heat.
Before Melloni, people thought the Moon was "cold" because they could feel it didn't warm their skin at night. Melloni proved that our senses were the bottleneck, not the reality

The space suits are actually multiple suits. There is an inner liquid cooling garment. A ventilation, oxygenation, dehumidification system. Then outer layers of extreme insulation made of multi-layered mylar-like material.
The rover was extremely complex. That's why the first missions did not have one. 1st, regarding the tires, there was no rubber anywhere on the rover, not just because of the heat, but the -250°F cold would leave rubber unsurvivably brittle. The tires were made of a wire mesh.
Batteries were a major challenge. They were not rechargeable. There were two, so one could turn off if it began to overheat. The astronauts had to keep the rover parked in the shade to prevent overheating. Operations were daytime (~2wks on the moon), so persistent cold was a non issue.

Lunar nighttime lasts about 2wks w/ temps -250°F!!!

They went in the transition zone.

First, this is not Political.
Second,
You think we had a carbed inline 6 powering it?

The tires were basically all metal, like wire rope baskets.

But it's a dry heat, as there's no atmosphere.
Yes, the suits were climate controlled.

You know you can research all of this stuff for yourself, right? It's not top secret.

The moon surface power was provided by a thermo-electric generator.
The company that built it is based in Calgary Canada. They were bought by and then spun out of Gentherm a few years ago.
I was the banker on the sale for the spin off. The tech is extremely cool and the unit is still active to this day. When we were doing site visits for the buyers and the question of durability and longevity came up we would ping the unit on the moon and would respond. One of the coolest things I’ve done.

Since we went to the moon 6 times ~50 years ago, why did we need to do a practice run?? I haven't been to the creek I played in as a kid in 50+ years, but wouldn't need a practice run to find it today.

It will soon be illegal to ask these questions, as it is illegal to ask question about the 6,000,000 figure.

CR2025 is what's in my Tru-Glo red dot on my turkey gun. Seems like everything else uses a 2032 or something like that.

Then there is the high, deadly levels of radiation to consider... but... sssshhhhhh. Just go with the narrative. It's easier that way.
