Yes, electricity for water pumping is subsidised, and the water itself is not taxed. Imposing even tiny charges on water consumption by farmers would incentivize them to use water more efficiently. India could easily learn water efficient p

The risk analysis for conversion projects comes out with a negative result every time. You spend a lot of money, and the best case is you end up with the same services as before.

"First they ignore you, then they laugh at you, then they fight you, then you win." Sounds like EVs are at the "then they fight you" stage.

This is incorrect. Accelerated weathering of olivine can do the job, even powered by diesel and coal, for about trillion in capital costs and a trillion a year in running costs. That's one percent of world GDP. All the technologies inv

So the book is called Climate Capitalism , but the examples all show how centrally directed big government policy is what actually made the difference. Climate dirigisme would be more accurate.

That's a red flag for the relationship right there. If "not wasting money" is a core value for you, but "status" is more important for your partner, things will go sour sooner or later. Of course it's very diff

China is totalitarian, but it's a stretch to call it communist in any practical sense. China is paying the price of rule by KPI.

The real world has many trillions of parameters. Also, doing stuff in the real world is all about sensors. Progress on integrating millions of sensors into a robot has been slow.

It seems to me that, done right, agrivoltaics could result in a negative land cost for PV, in that the value of increase in crop production (animal or vegetable) could outweigh losses from land taken up by panel supports and associated equi

Cheap, effective, reliable, durable lidar in cars would be a good thing. But for self-stopping, not self-driving.

You just have to look in the bottom drawer of the locked filing cabinet marked "tax returns", in the sub-basement room with a sign on the door saying "beware of the tiger".

A multimeter doesn't put any load on the battery. A (decent) tester will have an appropriate load for the type of battery of about 0.05 to 0.1C, so for a 2200 mAh AA NiMH, about 110 mA to 200 mA. 10 - 12 ohm resistor for 1.2V nominal.

Yeah, see, it wouldn't. Transmission lines are priced per kilometre. Superconducting transmission will almost certainly cost more than vanilla SCAW (steel cored aluminum wire), and you still have to pay for pylons, bridges, and/or

I'm struggling with the claimed consequences. The electricity grid has losses of about 30 percent, so a fully superconducting grid could increase delivered power by about 43 percent, not an order of magnitude more. More compact MRI mac
