Progress in batteries are just astonishing. European car manufacturers are still using NMC chemistry because of its high energy density. Chinese manufacturers use high density LFP at less than half the price and charge 5 times faster. Their LFP now reaching the same density as NMC. In 2025...

New batteries charge in 5-10 minutes even now. We are years behind Chinese companies.

So you would replace a 400V battery of a hybrid or electric truck with a gantry plus infrastructure on the streets to power it? Besides all the usual problems with maintenance, lane interdiction to a lot of other vehicles, traffic management if a truck needs to start stop, ugly looks etc what...

How high you want to run your overhead cables? How many lorries are allowed to charge on one set of cables? What is the voltage? What is the procedure if one lorry breaks down? It does not compare well with magnetic loops buried under parking spots.

so the guy increases the radiative surface and claim it saves fuel? I can understand why he claims it heats faster for a short moment but energy efficient? Not. The old pot is perfect for slow roast in the oven.

Merry Christmas everyone!

I think the problem is legacy automakers don't have the money to invest in new plants and shutdown old ones. We in the west (and also in Japan and South Korea) finance our investments with borrowing. We loathe any project that involves government subsidies, causing opposition to projects that...

The top article was dated 15 Nov 2022. At that time, gas was on extreme short supply.

Where did you get that info? Check the wholesale gas price pre Ukraine war.

When it comes to designing a 'cutting eddge' e-bike, why oh why are those people so keen to remove any trace of comfort that a normal e-bike gives?

Too expensive to implement and unreliable, I reckon.

By the time the EPR at hinckley goes into service, the problem with the rods made by framatome would have been sorted.

I watched a yt video about how charging networks charge electric lorries for recharging in Germany. The cost is basic kwh, about 15 cents, plus grid charge which varies with demand and supply. There is a proposal to fit a smart meter in the lorry which will tell the driver when and where to charge.

Hydrogen has transportation and storage losses too. The fair comparison is how many grams of CO2/KWH for hydrogen buses versus battery buses.

The next step is to let AI to clone itself about 10,000 times then let those AIs work out between themselves what science problems they want to solve and how to solve them. Within a few years, AI will transform science. Google AI already work on chip design of AI chips.

In China, and I guess also in some other countries, buses are recharged by induction loops buried under their parking slot at the end of the line. It only takes a few (about 10) minutes. They stop for their drivers to have a rest while being recharged so they don't seem to be interrupted.

How efficient are hydrogen ice?

Hydrogen cars and trucks are just evs with a generator on-board.

OpenAI has just unveiled o3. O3 is AGI.

VW group is firing 35,000+ workers. It's better to act now than closing car plants in the next few years but it may not stop there. With hindsight, they should have moved to EVs with more enthusiasm in the last decade. EVs are fundamentally simpler and cheaper to make.
