NYTimes: Nuclear Is Back on the Table for a Green Future

“Last year, global electricity demand was up by more than 6% — the largest increase since 2010 … Although available renewable energy sources like wind and solar have been increasing, their contribution is still lower than the increase in global demand.” https://t.co/qN0xrLLKPS

Battery weight is coming down

Battery weight is coming down

Lithium-sulphur batteries, which are lighter and cheaper than today’s models, may be the next generation of power cells that we use in electric cars or mobile phones – if scientists can get them to last for longer.

The main attraction is that they can store much more energy than a similar battery using current lithium-ion (Li-ion) technology. That means they can last substantially longer on a single charge.

They can also be manufactured in plants where Li-ion batteries are made – so it should be relatively straightforward to put them into production.

Rather than using costly cobalt, which is vulnerable to fragile global supply chains, they use sulphur, which is a cheap raw material available as a by-product of the oil industry. And their costs per unit of power can offer substantial savings.

So what is the hold-up?

The main problem is that current lithium-sulphur (Li-S) batteries cannot be recharged enough times before they fail to make them commercially viable.

Driving distances for EVs are still on the low side, max 400 miles (with marketing exaggeration) in *nice* weather (freezing temps will kill that performance), so maybe a solid 600 miles in winter weather is when they'll have made it and can start slimming down (taking weight off the tires) - another 4-6 years? (time to recharge is also a huge factor - 10 mins to get another 100 miles is likely no big deal - 30 mins is a prob - but we'll be likely hitting the former within 2 years?)

So this worry about tire particles will largely be solved by year 2030 (as will more of that exhaust prob).

"People have become appreciably fatter since reducing animal protein and fat intake, which has been largely replaced by copious, cheap, processed, albeit vegan, sugar. And figuring a food’s carbon footprint is more complex than quantifying cow farts."https://t.co/ho8qOd1aQy

Drought-stricken US warned of looming 'dead pool'

By Regan Morris and Sophie Long @ BBC News, Los Angeles, 11 hours ago

A once-in-a-lifetime drought in the western part of the US is turning up dead bodies - but that's the least of people's worries.

Sitting on the Arizona-Nevada border near Las Vegas, Lake Mead - formed by the creation of the Hoover Dam on the Colorado River - is the largest reservoir in the United States and provides water to 25 million people across three states and Mexico. Here, the stunning scale of a drought in the American west has been laid plain for all to see.

The water level is now so low that bodies of murder victims from decades back, once hidden by its depths, have surfaced.

One was stuffed in a barrel with a gun shot wound - presumably because someone thought it would stay unnoticed at the bottom of the vast reservoir forever.

While the dead bodies are fuelling talk about Las Vegas' mob past, water experts warn of even more worrisome consequences. If the lake keeps receding, it would reach what's known as "dead pool" - a level so low the Hoover Dam would no longer be able to produce hydropower or deliver water downstream. [....]
