How to get a cheap home battery in 2030
Buy a $5K cheap Chinese EV with say a 50kWh battery pack. Write the car off in such a way that it is not your fault, and most insurance companies will allow you to buy back the car for cheap if they write it off and pay you out, even if it can't be repaired and put back on the road. Buy the written off EV remove the battery and using a kit (available online by then) turn it into a very big home battery that will mean you pay nothing for power with a PV system without met metering. You can even top up your new replacement $5K EV using it overnight without paying the utility a dime for power.

No. You can buy unsafe crap in Oklahoma that won’t be registrable in California.

I'm sure they will be up to California standards and those of all 50 states, made in Mexico under free trade, perhaps sold under GM or Ford's name in some cases.

If by 2030 the Chinese can sell an EV for $5K with a 50kWh battery, they can sell a home battery with electronics for even cheaper!

Not for anything like $5k.

Wait... Nissan LEAF Battery Replacement Just Went OPEN SOURCE!?
The Nissan LEAF has been produced and sold in significant number for nearly fourteen years - and while the majority of those cars are some still happily rolling on their original, healthy battery packs many years later, others are in need of replacement packs.
To date, that process has either involved paying a Nissan Dealer a small fortune to have the battery pack replaced with an identical-spec one to that fitted in the car when new; or paying a specialist to replace the battery pack with a newer one from a salvage LEAF.
That latter process has relied on reverse-engineering of the Nissan LEAF's CAN bus and developing a hardware and software solution that allows older LEAFs to happily work with more modern LEAF packs. And that reverse-engineering is reflected In the costs associated with asking a specialist to replace the battery pack.
But now Daniel (Dala) of Dala's EV Repair in Finland has announced that he's open-sourcing the technique he's used to successfully upgrade customer's LEAFs to larger, newer packs.
Here's why that's a MASSIVE deal, and could dramatically lower the cost of LEAF battery replacements.

It's not that I'm skeptical about this transportation as a service idea and I'm sure many will use it, bars and restaurants that serve alcohol might like the idea too and it could lead to a revival for them. However, a car is a personal thing with many people and if they can own a future EV one on a whim for $5K many will, beats the bus and that might be the idea here, but buses move people more efficiently than EVs, can be electric, and parking is an issue for many. A transportation as a service thing could pick you up and drop you off at work, same in the evening, if traffic and demand wasn't an issue with everybody doing the same thing at the same time during rush hours.
The idea of the oil companies being out of business by 2030 seems a bit absurd, but they could be feeling the heat by then. The idea of a $5,000 EV in 2030 sounds absurd too, but they sell small ones cheaper than that in China today and batteries are getting better and cheaper while more robots are involved in production, and everything can be powered by renewables. China could get in through Mexico and free trade with assembly and battery factories there, labor is cheap too. A few years ago, the idea of solar being the cheapest form of power generation was absurd too. I try to keep an open mind.
Yep, call up an EV only to find some asshole shit on the seat or barfed all over the place while get driven home loaded drunk, there will be issues!
The remark about high-cost crude oil hits at the heart of the Alberta oil sands, whose output is forecast to rise by at 1 million b/d by 2025 and 1.5 million b/d by 2030.
If Seba is correct, the Alberta economy just suffered a mortal blow. Northern Alberta facilities and infrastructure worth hundreds of billions could be stranded. Calgary and Edmonton will be ghost towns.

However if transportation as a service is cheaper, I’m in.
The wrinkle is, my car is fully amortized. Operating costs are correspondingly lower. That’s the target they need to hit.

In 2030 if you own your own cheap EV and have solar at home, then your transportation is free, except for maintenance on the EV and when they get that fucking cheap, ($5K) they will be nearly disposable! What happens if you need to get to work and someone barfed in the car you called the night before while loaded drunk! There will be issues, large numbers of assholes roam wild...

If there is no cheap California-registrable ev in 6 years
what fabulous prizes will you provide?
Also, a disposable battery-anything is very ungreen. Imo the height of this folly was circa 1975 when Polaroid Land sold 10-frame photo packs for their flagship folding camera, each containing an overspecd battery in a pouch to operate the camera. I used more than one leftover battery pouch for other nefarious schemes (often rockets) requiring electric ignition.
Car-barfers will not escape unidentified. Chances are to use an on-demand autonomous ev service, you’ve signed a contract. Barf in a botmobile … get a surprise in your next card bill!

25% of our greenhouse gas emissions are from agriculture and most of that is from animal livestock agriculture that biotech might largely replace in a decade or so. She is as optimistic as me about the economics of the green energy transition and moves are already being made by industries. The data is trending the right way, and the curves should take a dive over the next decade, especially if biotechnology impacts our food system and livestock agriculture.

This is a very neat and important idea and seems to produce a lot of fresh water cheaply with solar energy. It looks like it can be engineered better and scaled to significant size near the seashore. After a couple of iterations to improve production and engineering to scale it to utility size, they might be onto something and could sell lots of them to the Saudis and other such places with a lot of cash. Using no energy to efficiently desalinate large amounts of water economically can make a big difference for people and the environment. It might enable limited agriculture in some dry places with efficient irrigation and hydroponics systems.
California here I come! Since it works in the day, solar PV can pump salt water to it miles inland to a cheap site and it drains back. Likewise solar PV can pump freshwater hundreds of miles inland with a pipeline or canal covered in solar panels. It also doesn't produce polluting brine, a good selling feature. Think hundreds or thousands of square meters of these panels in a more advanced design, perhaps using solar PV to enhance production further.
"The heart of the team’s new design is a single stage that resembles a thin box, topped with a dark material that efficiently absorbs the heat of the sun". That might be a solar PV panel of some sort... If it cools the solar panel as the top layer too, it's a marriage made for the desert coasts, power and water from the same facility. What would be the effect of concentrating solar on it with mirrors, say an extra square meter or two of extra sunlight per cell?
From these tests, the researchers calculated that if each stage were scaled up to a square meter, it would produce up to 5 liters of drinking water per hour, and that the system could desalinate water without accumulating salt for several years. Given this extended lifetime, and the fact that the system is entirely passive, requiring no electricity to run, the team estimates that the overall cost of running the system would be cheaper than what it costs to produce tap water in the United States.

Unlimited Fresh Water: Can MIT's Breakthrough Save Us?
This video is an exploration into a resent rabbit hole I went down. I read about MIT's new desalination breakthrough on Reddit, and needed to learn more! The topic of desalination is an important one that is only becoming more critical and could be a lifeline for huge area of the world. As well as looking at the breakthrough, this video also touches on classical methods (multi-stage distillation and reverse osmosis) and a case study of where this could be used, Kiribati.

Desalination system could produce freshwater that is cheaper than tap water
A new solar desalination system takes in saltwater and heats it with natural sunlight. The system flushes out accumulated salt, so replacement parts aren’t needed often, meaning the system could potentially produce drinking water that is cheaper than tap water.

This solar distillation apparatus mentioned above might produce 10 liters of fresh water per square meter if engineered and iteratively improved using some PV power or mirrors to drive the process for more production. A 1-meter square solar panel produces about .2 kWh of electricity and this thing might be able to produce both electricity and 10 liters of water per hour from the same system.
A typical 2-megawatt solar power system has about 10,000 square meters of panel surface area for instance and could produce up to 100,000 liters of water an hour, while the sun shines with this system, in addition to the electricity. Unlike electricity, water is easy to store and accumulate into large volumes eventually.
How about if the only utility scale solar the California SoCal utility was allowed to build was one of these dual power, fresh water generating solar stations? Leave most of the regular solar power generation to prosumers and be forced into this or wind power which compliments solar.
Imagine how much fresh water could be produced per day from gigawatt levels of panels that also produced solar while cooling the PV panels and absorbing the heat energy normally lost or that degrades the panel performance and using that heat energy to produce fresh water. How high would the total efficiency be, you would go from 20% usable total energy to something much higher.

These are the kinds of ideas that I love hearing about; they don't require an obscene level of investment to get started and can be very beneficial even if done on a very small scale. This doesn't involve getting an entire new industry established and should face substantially less resistance from existing water purification corporations as it isn't destroying an existing market, yet.This is a very neat and important idea and seems to produce a lot of fresh water cheaply with solar energy.

The thing about the present that is unlike the past, is things are often a global effort involving an awful lot of people, not a relatively few as in the past and everybody is linked together by the internet so news travels fast.
Imagine how much interest this solar powered distillation thing has in the engineering community globally, and there are thousands focused on this specific issue just in arid countries or regions. They look at this solar freshwater apparatus and can immediately see that the top absorbing layer can also be a solar PV and it can solve a problem with solar PV too, heat. A bit of thinking and math will come up with the theoretical limits and it might be less solar PV more water or the other way around, the classic compromises. There might be ways of driving additional freshwater production by pre heating the seawater before it goes into the cells. Designing the cells so they are not too much thicker than a solar panel and can be deployed like them, except on an angle. There are many possible improvements, and thousands of people are looking at this, making CAD designs and sharing ideas on discord servers globally in multiple languages. Progress can be fast and there seem to be no bottle necks in getting this from the lab to the fab quickly. It could make a financial killing in some places, so expect those engineers to get the capital.
