GM’s decision this week to phase out gasoline vehicles is the latest in a major shift that will mean drastic new demands on electric utilities. Here are four things that will need to happen.
1) batteries are tuff to improve (we'll see with solid state, and it may be improving charge times is easier than capacity/charge density
2) as Gates notes, this is still the easy side of things - lowering the carbon footprint of cement/concrete and airplane fuel is a much huger deal than even autos. Though I don't know how fast these are growing, and what electrifying autos does to *balance* emissions, vs grossly decreasing. I.e. despite absolutism, there is something to be gained in greatly improving the situation without the much harder task if making all fossil fuel use go away.
Also, the electric car conversion, esp Tesla, has gotten caught up in the Full Self-Driving craze, with claims and promises of Self-Driving fleets, etc. This of course is at least a decade away to do safely - improved hardware (more powerful GPU chips, better cameras & LiDAR sensors, much better AI/learning, 6G for massive data sets and terrain maps to train on...)
For the last six weeks, a nondescript building on Studebaker Road
has quietly been sucking up electricity, then doling it back out when
needed. Wednesday, AES Alamitos will celebrate the successful
completion of its Battery Energy Storage Project, or BESS, with a
virtual ceremony. It marks the end of the construction phase of a
$1.3 billion rebuild of the AES Alamitos Energy Center.
Tesla Powerpacks used to form the world's largest lithium-ion battery at the Hornsdale wind farm, near Jamestown, South Australia.Two years after Tesla Inc. installed it, the world’s biggest lithium-ion battery is helping to avert blackouts and lower costs as Australian grids struggle to handle surging renewable power generation.
The Neoen SA-owned Hornsdale Power Reserve has responded to three major system outages, helping to restore stability to the network and lower the costs of running the grid, engineering consultant Aurecon Group said Friday. The battery started in 2017 after Elon Musk famously won a bet that he could get a 100-megawatt system up and running in 100 days to help solve a power crisis in South Australia.
new, clean mass transit is one thing; old mass transit quite another, maybe obsolete!
A new study has found troublingly high levels of the very fine particulate pollution PM2.5 — named for the size of its particles, which penetrate deep into the lungs — inside dozens of subway stations throughout the Northeast, @awalkerinLA writes https://t.co/oCqyAFjmU7
Honestly this is astonishing and moving. All this science, engineering, and discovery (with knock-on benefits and soft power pride, for this is America at its best) for just $2.7B. https://t.co/ebT2mTOucV
And all those who worked in it who came from overseas, and who contribute from other countries. It is America at its best, an inclusive USA giving opportunities to talent from wherever. Let’s see the country as a whole do this in all areas.
the Mars Rover has its own Twitter account apart from NASA general (note included in the description is a list of its hobbies) it is tweeting this evening:
Did people really think that if the Russians got to the Moon first we’d all have to do Communism or was that just an excuse made up by people who thought it would be cool to go to the Moon?
”When nations build nuclear plants, carbon emissions reliably fall and when they shut them down, as we’ve witnessed over the last decade in Japan and California, they reliably rise.” https://t.co/Jbrg3cHeHm
Another decent essay - boring strategic persuasive grunt work goes better than activism and agitprop? Who knew? Actually i did from back when Bono started getting invited (inviting himself) to boardrooms rather than leading street protests.
The HIV is not one type of virus but a group of rapidly evolving strains that are difficult to rein in.
Scientists constantly scan blood samples across the world to detect new strains. And a remarkable development in the Congo could have worldwide implications.
A high number of individuals in the Democratic Republic of Congo (DRC) have been found to have HIV antibodies—that developed as an immune response to the virus... but have no viral infection.
It is rare to find someone with antibodies, without the virus, say healthcare experts.
Global surveillance of 46 countries over 25+ years has not shown up results that DRC has revealed.
“This is the part of the world where HIV has its origin, and it is truly remarkable to think that the cure could also be unlocked here,” said US-based Mary Rodgers to The Ken.
Back to that debate about the woman who had a particular medical physiology to mine and use for others, and "should her family be compensated". Who will sell first?
Of 10K+ participants screened, 4.3% were categorised as ‘elite controllers’ of HIV. They naturally suppress the virus, without medication.
India—home to 2.1mn HIV-infected people—could benefit from the clues these 'controllers' throw up. Read more:https://t.co/xJmOGL8mgY
Deepfake technology first emerged in 2017. It is able to place politicians, celebrities or just any normal person into a video they never participated in, making them say or do things that never happened
Nature asked six scientists from South America, Africa, the US and Europe what they miss most about pre-pandemic science and what they’re most looking forward to when — and if — the scientific enterprise finally and fully restarts. https://t.co/klYJVwrTi6
He may have slowed down in difficult areas and software evened it out for the final recording. The whole original recording might have been done much slower and during the final editing process he picked a speed that felt right to him.
$4K is A LOT for a bike if you think of it as a bike. But if it replaces a second car, it’s the much more economical choice.
I haul two kids all around town and pay nothing — zero, zip, zilch, nada — on insurance/parking for an ebike that, unlike our car, is already paid off. https://t.co/X0lMorzjUX
The thing about ebikes is that it’s not like you’re making some high-minded sacrifice purely for the good of the planet, you’re just choosing the fastest, cheapest, most enjoyable way to get around the city. Feeling smug about the environmental benefits is just an added bonus!
Cock ≠ sperm, i think you know. The good news is we can use the lower birthrate for a while (esp if included SubSaharan Africa). But eventually the cockroaches will win. Or we invent a non-plasticky plastic if it ain't too late.
Very interesting about the strong difference in genetics with dogs! Have never seen that explained before, but have certainly heard people incorrectly talk as the same could be done with humans.
