Re: Just slowing down.

Nice to hear from you again RC. I am not convinced though that merely sending these folk a letter will have much impact on their behavior. It depends upon what the letter says! "In the event of future offences you will be taken to the Tower of London and fed to the Royal lions*" would be ...

Re: BA flies carbon-neutral flight

Greenwash. Only limited volumes of waste cooking oil are available, and then only in affluent nations. The supply is likely to reduce and not to increase. I would prefer that such light green fuel be used for essential purposes such as emergency vehicles, life saving flights, and railway freight. Ai...

Re: Co2 crisis and meat supplies

Some animals are placed in an atmosphere of carbon dioxide to render them unconscious before being killed. There are alternatives, as used by small holders, but these these are not applicable to large semi-automatic slaughterhouses. Chickens may be grabbed and either beheaded with a sharp tool, or h...

"No chance the lights will go out this winter" says government spokesman. https://www.bbc.co.uk/news/business-58620167 A sure sign of impending doom :lol: Or to be more accurate, he said "no chance of the lights going out DUE TO HIGH GAS PRICES this winter" My emphasis. In that h...

Agree, the main merit of bitcoin is that governments cant print more of it as they are apt to with paper money.

Re: Just slowing down.

I cant imagine speed reductions on that sort of scale being achievable. I and a few others have previously suggested that the default speed limit on rural roads be reduced from 60 MPH to 30 MPH. That produced howls of outrage. I would support the following speed reductions. From 70 to 60 on motorway...

Re: Multi-breadbasket failure

I suspect that the fertilizer plants will soon reopen. Reports state that the American owners are in/soon will be in talks with our government. I expect that some form of grant, subsidy or other bung will be paid to justify operation that would otherwise be uneconomic. Such payments may be justified...

Re: Gas supply crunch

The gas price/supply issue is now being more widely reported by the MSM. It was the main story on the late evening BBC TV news yesterday evening for example. The consequences for electricity supplies, fertilizer production, and carbon dioxide were also mentioned. A government spokesman assured us th...

Re: World’s first battery-electric freight train unveiled

I very much doubt that we will ever see a nuclear powered train. The smallest* nuclear reactors are those used in submarines, still much too big to fit on a railway, and hugely expensive. All busy railways should be electrified. Battery power is realistic for short lines, branches, sidings, and shor...

A doomerish neighbour has just ordered a second bulk propane tank, and ten loads of logs.

I have ordered extra logs and some more paraffin.

Re: Ongoing food and skills shortages.

The BBC also reports CO2 being used in nuclear power plants, but I have no idea for what Circulating carbon dioxide is used as a heat transfer medium in some types of reactor. It becomes heated in the reactor core and passes through a boiler to raise steam that works a steam turbine. The carbon dio...

HMG "are holding urgent talks" about the gas crisis. They again reassure us that the UK "has very diverse sources of supply" for gas.

Re: Electrolytic production of hydrogen

Certainly impressive. It would make more sense to use the renewably generated electricity for general domestic and industrial purposes, instead of burning fossil fuel to produce that electricity. If however the scale of this proposed plant is so great that existing domestic and industrial electricit...

Re: World’s first battery-electric freight train unveiled

Electrification is best, but in places lacking same, a hybrid battery/diesel locomotive can save significant fuel. 100% battery power is possible if distances and speeds are modest. The USA does have some electric railways, but only a small percentage of long distance routes are electrified. Part of...
