Re: New coronavirus in/from China

UK infection numbers have resumed an upward path, but well short of the 10 day doubling rate seen earlier. A new sub-variant dubbed Delta-plus which includes a key mutation in the spike protein also found in the Beta variant has now reached 44 identified cases in the UK. India has declared it a vari...

Re: Current Oil Price

Brent breaks $75. This is the highest for 3 years. Pound is relatively strong over the dollar, so the local price is not so high at the pumps yet.

Re: Are we on the brink of an electric car revolution?

Some of the cheaper models have a lot less electronics, I think the base model Corsa e and the Chinese MGs. Maybe the fiat 500e. However, cars in general are better described as computers on wheels these days. They all have the high tech sensors and computer controlled drive trains and built in emer...

Re: Economy and recovery

I'm not sure that the EROEI requirement of 5 quite applies in the case of tar sands. As far as I remember, for each 3 tonnes of tar extracted, one is immediately burned as a heat source to help melt the tar in situ so that the next 3 tonnes can be extracted. (this is a simplification I a sure). So t...

Re: New coronavirus in/from China

Infection numbers in the UK have fallen for 3 days now, admittedly over a weekend so could be a weekly artifact. Numbers are levelling off in the hotspots, although stll rising rapidly in more rural areas. We could be seeing the low vaccine areas approaching herd immunity at least at the current lev...

Re: Labour Party Watch

I hadn't even realised there was a by-election, there was so little media coverage. But how is a swing away from the Tories of 24,000 votes reported here as a defeat for Labour? I was wondering what the local reasons were that the Tories did so badly, and I found 1 HS2 goes through the constituency ...

Reports of incident at Chinese reactor

https://www.bbc.co.uk/news/world-asia-china-57496831 Partial meltdown of fuel rods leading to gas escape and presumably some radiation release, although the Chinese deny this. The plant is joint run with a French company. Not sure of the reactor design or age, I assume it is water cooled. (PWR?) I'm...

Re: Are we on the brink of an electric car revolution?

Currently the clear trend is bigger, heavier, far more powerful than necessary. They are still selling at the premium end of the market, which is in direct competition with the ever growing SUV arms race. Self driving is currently a pipedream in UK's messy, untidy and busy streets. Range is still a ...

Re: New coronavirus in/from China

China has fallen off the radar of covid infections, but they are now struggling to keep the delta variant out in port cities, and local lockdowns are impacting on international trade again. Chinese vaccination rates are low. Most of their vaccines have been exported. Rates are also rising again in B...

Re: Are we on the brink of an electric car revolution?

Twp more trips to the garage, one to fit the replacement hardware, and a second to install all the software updates, and the car is back to working. At least they gave the car a free charge to cover my travel costs. As a note, the government taxes electricity at recharging stations at 20% Vat, not t...

Re: New coronavirus in/from China

The BBC is reporting that the Delta variant is 60% more infectious than Alpha, and hospitalisation rate 2.2 times higher in the unvaccinated. Interestingly, of the 42 people to die of Delta variant, 12 have been fully vaccinated. I think this shows that if you are very frail or generate a weak immun...

Re: New coronavirus in/from China

https://www.youtube.com/watch?v=OHBua3aXQ7c The delta variant is progressing very much as expected. its 'natural' R0 value is about 6, which equates to 1.3 in the UK as a whole today and 1.8 in London with its low vaccination rates. Estimated 10,000 symptomatic cases per day, doubling every week. Th...
