Re: Samsung Heavy partners with the Korea Atomic Energy Research Institute to develop nuclear-powered ships

It looks like Russia/USSR have had more nuclear accidents than the rest of the world put together and they are building even more vessels to have accidents with. If they were a car driver going for an insurance renewal no insurance company would touch them.

Re: Extinction Rebellion, ongoing disscussion.

The turbine is definitely 12V as I had to chose when ordering it and they rewired it from 24V. With a 24V battery system set up as two 12V banks connected in series can you take a connection from the 0v, the negative, and from the 12V + to an inverter and then take a connection from the 12V - to the...

Re: Generator fault.

................BTW, I recal a demonstration years ago. A large diesel engine was running on load at a constant speed and generating electricity. A SMALL percentage of natural gas was introduced into the combustion air and the engined continued to run as normal, but the engine governor was observed...

Re: Generator fault.

We recently got the genny back at a cost of just under £900 after it had a complete rebuild: new bores, pistons, rings etc. We are now having problems with it rattling itself to pieces. Various bits of peripheral brackets have failed, some twice even after we have bolted the machine down using new b...

Re: Extinction Rebellion, ongoing disscussion.

I have had a 300W 12V wind turbine sitting in the cellar for years because I can't work out how to get the power from the turbine to the battery store, a distance of about 30m including down the pole, affordably. The only way that I thought it could go is suspended along poles in the air but that ca...

Re: Swiss voters reject key climate change measures

................. I suspect that in years to come, that total global fossil fuel extraction and use will remain at levels broadly similar to todays, but that most nations will announce that they have reduced THEIR emissions by various forms of trading and offsetting. And the temperature will contin...

Re: Solar power from Australia to Singapore.

The article that I saw, https://ideas.ted.com/solar-farm-sahara-desert-climate-impact-effects/, on changing the climate related to the Sahara and was based on the fact that the solar panels are much darker than sand or rock and vast areas of darker material would produce much more heat and would be ...

Re: Swiss voters reject key climate change measures

If the government started giving away goodies, such as "no cost" insulation of houses, they could get a lot more people onside. When people see Housing Association houses being improved and the comfort levels improving vastly at no extra cost, although some of the savings could be taken ba...

Re: Solar power from Australia to Singapore.

I saw an article, in the Guardian i think, about how large scale solar farms in desert areas could change climate over large areas due to the difference in temperatures and humidity caused by the difference in absorption and radiation between solar panels and desert sand. It's all a matter of degree...

Samsung Heavy partners with the Korea Atomic Energy Research Institute to develop nuclear-powered ships

The fact that Samsung Heavy and the Korea Atomic Energy Research Institute are developing nuclear-powered ships has me very worried indeed especially as, on average, one large ship a year just disappears and another one hundred are lost or founder (sink to you and I). Unless there are very stringent...

Re: New coronavirus in/from China

My first reaction to that is aren't those people stupid. In reality many of that sort of people are not at all stupid. They are however very selfish and o...

Re: Preparing for extreme heatwaves.

Many people in the UK cannot see the logic of keeping the windows closed and shaded on a hot day and opening them at night, unfortunately. I have seen many a person sitting in a fan oven breeze by an open window insisting that they "like a bit of fresh air on a hot day!" And they look at y...

Still only about half the all time high of about $140 reached some years ago.
How about the price allowing for inflation. I bet that it's not far off the $140 on that basis.
