Yes people on farms need big vehicles. We're not talking about them.

Your attempt at logic is very wrong.

I think there might be multiple groups in play there

Answer: Light slows down when going through water or air or gas. It's only in a vacuum that light travels at 'c' (from Einstein's equation). And it's that speed c that is a limit due to relativity.

But the exciting thing is that when you're not in a vacuum particles can be traveling faster than the local speed of light (maybe 75% c). And that process of a particle zipping along gives off Cherenkov radiation.

I think of it as the light equivalent of a supersonic shockwave and sonic boom. Faster than sound gives noise. Faster than light gives light (or other electro magnetic radiation)

(People with more knowledge might say the sonic boom analogy is very inaccurate but not sure)

My understanding is that there are large savings available theoretically at the grid level but the capital to build it is limited and the grid interconnects to make it work are limited.

So globally there are huge amounts of battery storage being added to the grid but this is bottlenecked by capital and grid connections. Oh and land/planning permissions.

Long story short, house level battery storage may be worth it for some people

This is for the Japanese market so perhaps the cons of the C02 systems are outweighed by the safety aspects.

Interestingly the story of the Thylacines extinction starts a lot earlier than white settlement.

"The fossilised remains of thylacines have been found in Papua New Guinea, throughout the Australian mainland and Tasmania.

Factors including the introduction of the dingo led to the extinction of the thylacine in all areas except Tasmania about 2,000 years ago. The thylacine population in Tasmania at the time of European settlement is estimated at about 5,000."[0]

This quote amazes me. My understanding is that Airbus, Qantas, and probably Rolls Royce were willing to spend this much because it meant that the incident was not a "hull loss" and therefore not as bad a hit to reputation and safety statistics. Does anyone know if that's true?

" Q-Collar is a C-shaped, non-invasive silicone neck band designed to help protect athletes' brains from repetitive sub-concussive impacts. It is worn during high-impact contact sports like American football, soccer, lacrosse, and hockey.

How It Works -

Jugular Compression: The band applies light, safe pressure to the sides of the user's jugular veins.

Increased Blood Volume: This mild pressure slightly slows blood outflow from the head, increasing blood volume in the venous structures surrounding the brain.

Reduced Brain "Slosh": The extra blood acts like an internal cushion or seatbelt, minimizing the movement (sloshing) of the brain inside the skull during an impact. "

They weren't talking about breaking into the Iron Mountain facility
