Green makes me see red.
Made in China…..according to their site.
The other consideration, in the solar-wind-battery scenario with “overbuilt” solar/wind, is to exploit excess peak capacity with easily interruptible loads. There’s a move afoot to develop aluminum smelting in such a way as to be able to turn the electricity it uses off and on. That would certainly seem attractive. In arid regions you certainly might want to use the “excess” power for desalinization. Surely that would be easy to start and stop . . .
I was just taking with a retired chemistry professor about this. She was stunned the industry wants sodium batteries.
as I noted initially. But with the raw materials plentiful in the US, and under the “Inflation Reduction” Act, Chinese companies site facilities in America for lithium and, presumably will for sodium, ion batteries. Brian Wang said on youTube that it would be no trick at all for Tesla to make sodium batteries on equipment it already has, slightly modified.
Now the Chinese are going to put all those poor African children out of work
Understanding that I am a fan of customer-owned and operated solar power (co-generation essentially) and NOT utility-owned large-scale solar, I am wondering when the legit climate folks will look into the impact of large solar panel fields on what’s called planetary albedo, although localized. Just like concrete and steel cities act as heat sinks, large solar panel fields, designed to be as perpendicular as possible to the incident angle of sunshine, are likely to reflect LARGE amounts of ‘heat’ into the atmosphere.
... has the advantages of high-energy density, fast-charging capability, excellent thermal stability, great low-temperature performance and high-integration efficiency, among others.As others note here, funny how he doesn't brag about its cost.
I’m not aware of any advantage Li has over Na other than its (very important for transportation) energy per Kg of mass. Na seems preferable for stationary applications, pretty much on all counts that are publicly mentioned.
I’ve seen discussions of ways to maximize radiation to outer space in places other than deserts (which get cold at night due to that effect). Such technology obviously having application as an aid to air conditioning . . .
btw, here for a 2022 study from Cornell on the limitations of Sodium-ion batteries:
https://news.cornell.edu/stories/2022/02/engineers-reveal-cause-key-sodium-ion-battery-flaw
“Huang said the new characterization technique can be used to reveal complex phase behaviors in other nanoparticle systems, but its best application may remain in next-generation energy storage technologies.”
Just add water.
A Tesla Model 3 sedan now costs less than the median new car sold in America - and it actually isn’t all that heavy. Performance is worthy of the name. Versions with real zip are available (but do cost more).And you are almost forced to purchase a new car because after 8-10 years you will have to replace the battery pack at a cost that is more than the value of the car. So your 8-10 year old car is basically worthless.
The experience of Hertz is that Teslas are good rental cars - not too expensive, and require less maintenance (and electricity costs less than gasoline per mile). It turns out that modern batteries don’t degrade nearly as fast as I feared (and you still think). Batteries seem to hold up better than gasoline engines. And if the kw/pound of your battery degrades to the point where you need a new one (after, say 250,000 miles), the old battery is still useful for stationary storage.I won’t trouble to debate every point, tho I could - but let me just end with the fact that the best way to charge is overnight in your garage using 220 volts - which you probably don’t have in your garage already, so that’s a cost. The adapter to your car doesn’t cost “thousands.” And the juice is less expensive than gasoline, per mile.
The only way solar or wind with batteries works efficiently is if you do it yourself (or have a professional do it for you). That's why my home solar has provided 81% of all the power we needed in the past 12 months, including charging the EV. I have a vested interested in making sure MY system works for ME. Bureaucrats don't have that motivation because it's not THEIR system working for THEIR benefit.
This is the “we need to destroy Earth in order to save it!”
I just hate ugly solar cells and windmills. Now add to it massive batteries! What a waste of resources!
The main problem - solar density is not that great, wind is not that big, to satisfy our energy needs. Massive buildup in solar and wind will use both fields and nature reserves, kill wildlife. Make massive mines. Just the opposite to green!
As long as we have enough fossil fuels we are OK. Nuclear power can last us millennia!
And sometimes in the future, we will solve the nuclear fusion problem and get almost unlimited power sources from them. After that some other energy sources will be developed!
People will look with horrors on the way greens destroyed the planet in early 21st century!
Steam has powered America for a long time and works quite well. (nuclear, coal, nat gas.. all produce heat to make steam)
Solar is getting cheaper, my latest panels are very nice 100watt panels and were 58.99/each with free ship at Amazon.
I have a lot of 100Ah LiFePO4 batteries.. in fact I have overbuilt. I am building my own charge regulators so I will
know how to repair them if the need arises... and I have plenty of replacement mosfets for them.
I will get an EV when the batteries don’t burst into flames. IMO only a hybrid makes any sense as I wouldn’t want to be stuck out with no way to charge the batteries or get stuck in a snow bank with no heat...
Small, cheap, SAFE EVs make sense in a dense urban environment but would be a bit problematic in rural areas.
“CATL’s battery capacity is expected to reach more than 670 GWh by 2025”
wow! that should be enough gigawatts to get back to the future!
An essential thing is the charge/discharge graph. Just by looking at it, you can tell what the best application for the battery will be.
The communist chinese make 97% of the solar cells.
Using slave labor is as cheap as the cells will get.
