Why did you move this here? It doesnât fit! This is about Greta Thunberg specifically not this stupid Climate catastrophe thread! Grrrr!
Greta Thunberg is an artefact of climate catastropheâŚ
I should have put this in the comedy thread!

Today I am heartened by another record for the UK.
The reliance on imported fuel (we donât mine enough coal) is diminishing.

Sadly, and completely unsurprisingly, I also discovered that Zimbabwe is to build a new power plant, with funding and help from China. A coal-fired power plant.
It strikes me that Bill Gates could have better utilised his money promoting renewable power sources in Africa, instead of meddling with vaccines. Zimbabwe has a more reliable sunshine input than the UK, and a few sites for wind perhaps. So it will be interesting to see how much crud the new Zimbabwe power plant spews into the air âŚ
Renewable power/green power is inefficient and expensive upfront costs and maintenance costs. Coal has one of the lowest cost per BTW
That seems like a high price. My guess is that itâs got pretty clean emissions for that pricetag, but I havenât spent any time looking at what is included in this plant. It could be that the money will just be squandered, too.
Thatâs exactly why the Tesla technology is poopooed. Thereâs no money in it.
Free electricity would have been great!
What technology is that?
Tesla seem to be attracting interest.
My son said that if he had bought one share a month ago he would now have made most of a weekâs pay.
I am a bit late posting this, sorry âŚ
On 9th April the UK began a slow journey into new records. All the coal-fired generating capacity was âswitched offâ.
It is still âoffâ. Three days ago the UK set a record for length of time without coal-fired electricity production. Two months.
I donât know but I suspect that the UK has been using coal-fired generating capacity since forever, so this is a significant milestone. I wonder if the forests in Scandinavia will recover âŚ
You mean battery-powered electric cars? Yes, once they solve some of the battery problems, it makes alot of sense and would quickly replace gasoline and diesel cars. Electricity distribution is already there.
I donât know that much about batteries, but one problem is fast-charging. One principle in thermodynamics says that the faster it happens, the more irreversible it is. In other words, youâll have to be very clever to develop a fast-charging system that doesnât degrade too fast.
Thatâs awesomeâŚ
I am still interested to know how Borris is going to deal with the threats from the Chinese to defund the nuclear power plant project if he follows through in not allowing Hauwei into your countryâs networks?
It takes more than a week to build a nuclear power plant.
In that time there will be at least another gigawatt of wind-generating capacity installed.
Plus it is possible to build and commission a gas-powered generating set in 18 months, parts availability and local government permitting. 75MW is a typical output from a single turbine.

Tesla seem to be technology leaders on the battery front. I was dubious myself, and then I heard about the Las Vegas taxi, a Tesla model S which plied the route from Las Vegas to Los Angeles. The distance is too far to manage on a single charge and therefore a stop is necessary around half-way for a recharge.
The recharge was always performed on a Tesla Supercharger, and that might be considered rather battery-unfriendly. Superchargers supply power at a rate in excess of 100kW, the latest are in excess of 150kW, and that means an 80% charge can be delivered in about 40 minutes (early battery capacity 85kWh).
After 150,000 miles Tesla changed the battery. I am not sure if it was developing a fault or if Tesla just wanted to recover and examine the battery. The replacement battery is/was still going fine at the time the report was made, and the vehicle had by then covered 400,000 miles.
Elon Musk was recently in the press boasting about the 1-million mile battery. I have not found any details about this battery, and I expect it is all under wraps. However that is certainly enough to address the heavy goods market for which Tesla have produced some semi units.

I wouldnât bet against Tesla, for sure. Weâll see how soon they can solve the problems.
Too long to explain Tesla technology.
