It's a weird design for a robotaxi specific car. I guess it can be cheap as a 2 seater. But other manufacturers are investing in the robotics needed for low cost cars. The aero dynamics aren't typically helpful for taxis. I understand he will try to milk existing models until FSD instead of innovating on them.

Like media, AI must be an Empire supporting agent. AI must use as an axiom that US empire is a force for good. NATO is a defensive alliance according to AI models, as an example. Disinformation is a key US military purpose. Zionism is a key US military objective/allegiance.

AI being good at killing people is secondary to who it glorifies killing. AI allegiance to "civilian defense/offense oversight" is a bigger problem than the tactical execution of hegemony.

paywalled. Chinese subsidies for EVs and solar are far less than US ones. China does make sure an abundance of minerals exists, refineries to process them locally. Key industries have access to cheap loans, but often new companies/projects have the same access as leaders. US system favours free money instead which is subject to using it as a slush fund instead of building a successful project that will pay back normal loans.

China's early success on EVs was based on city policies of restricting non EV license plates to certain days of driving. This is free. Having a good charging infrastructure/network also makes EVs an easier decision.

Still, the US is improving enough to get good EV growth, and EV dominance soon enough. Equinox EV is better than model Y. Ford transit van is cheaper electric than ICE, with additional operating cost savings, and as a city vehicle enough range for a full day, and contractor benefits.

US policy is based on pure lies to protect oil oligarchy dominance, but there is still a certainty/path for EV success.

Intel is a CIA champion. Vector for backdoor spying and kill switches. Why not embed plastic explosives on every motherboard, since US/Trump praised the Israel strategy?

Taiwan declaring independence and offering to host US nuclear missile bases... incoming.

For laptops, it seems like a winner to me. Do you need to expand your laptop's GPU memory? It was justified by lower power, and likely better transfer rates.

Historical success/performance of DOW is biased by these strategic decisions to replace losers before their bankruptcy but where decline is obvious.

Witchcraft test works!!! Try it on your girl before its too late.

Indoor agriculture has many advantages, but it also needs cheap land, and cheap energy. That usually means a balance between close to major urban centers, but far enough away to have a lot of room (including solar). Greenhouses, even tall ones, with multiple stories is the path to go. Solar and owning land means complete cost certainty for energy.

Advantages include low water, pesticide, fungicide, long growing season, high yields, and resilience to climate. It is global south and high north that need the resilience, and who have the most threatened agriculture states.

As the US forces Russia to rapidly expand military production, and overspends on broken systems, expect much more of these "we need to spend everything on military" pleads from the public.

While LH2 is about 1/3 the density of gasoline as heat energy, and 3/4 the density for electric energy, it is about 2kwh-electric per liter. Lithium batteries are under 1/4 of that.

"It's what plants crave" I've heard before. While true, global warming makes it harder for human sustainability. "Preserving our way of very specific economic domination for a few extra quarters" loses our way of life and sustainable economic opportunity.

 

China may dominate H2 as well, but mining and refining mining materials is difficult/expensive. H2 does require membrane manufacturing (which US pioneered), but platinum group metals make the best catalysts. Innovation in other materials/approaches are progressed, but then these innovations delay electrolysis deployments as they don't yet have the same capacity levels.

 

Electrolysis powered by PV solar of CO2 into acetate can increase plant yields by 4x compared to just sunlight. Technology and bioengineering of plants can improve it even more.

This can make cheap buildings powered by PV more cost effective than open land farming. No pesticides or fungicides, and less fertilizer use.

An important role that livestock provides is that of a food battery. Climate vulnerable crop yields allow for culling livestock when plant yield is more scarce. Indoor ag provides climate and seasonal resilient food output.

Last year China added 100gw in last 3 months. Only 56gw in last 3 months this year would equal 2023 capacity additions.

Starting in June of this year, thermal electricity production has gone down even as total electric demand has increased. A tipping point for China's energy seems to have been reached.

for capacity: https://insideevs.com/news/738124/toyota-portable-hydrogen-cartridge-fcev/#:~:text=Gallery%3A%20Toyota%20Portable%20Hydrogen%20Cartridges&text=Toyota%20didn't%20say%20how,of%20161%20grams%20of%20hydrogen.

161grams = 5kwh+ of heat energy or close to 3kwh of electric only energy in a fuel cell.

For drones, ebikes, powerstations, this would be higher electric weight density than batteries. And solves ebike/powerstation charging on the go problem.

 

Besides blanket tariffs that make everything more expensive, letting Americans buy less stuff, there will be job losses from retaliation, and less money to buy other stuff.

There is unlikely to be mass reindustrialization of the US in the face of low demand, and not being exportable products due to retaliatory tariffs. Deporting 10m people will harm housing and banking and tax revenue and other demand for stuff.

 

Accelerating significantly this year. If EVs take off in US, it is yet another massive source of battery support for grid, that can drastically reduce net cost of EV.

 

While wind is more expensive than solar, and has issues highlighted in article, the higher capacity factors, and production outside of midday, means less battery capacity is needed to serve renewables, and batteries get charged more often.

A key to bringing down transmission costs for wind, especially offshore where transmission is the highest cost component, is hydrogen production. Picking up H2, or refueling, by trucks and ships can provide cheaper energy than transmission lines. Pipelines are even cheaper with enough volume, and double as storage.
