Re: New coronavirus in/from China

An article on CNN last night saying Delhi area is running out of oxygen, people making appeals on Facebook. People trying to point the finger at major gatherings such Kumb Mehla (probably misspelt). Right decision taken a bit late. Could be descriptive of the whole Covid saga. Since the above was p...

Re: Grid gravity storage

I suspect that the costs and complications might rule this out. A 120 ton weight in a deep mineshaft would store about 480 KWh A similar weight in a more typical depth mine shaft would store perhaps one quarter of that or about 120 KWh. I am not convinced that the cost of the installation would be l...

Re: "78% cut in UK carbon emissions by 2035"

I strongly suspect that most politicians and most voters don't know the difference between "energy" and "electricity" They look at the progress made in renewable electricity generation, and ignore the FF used for transport and domestic heating. I also suspect that most of the &qu...

"78% cut in UK carbon emissions by 2035"

Our government have announced plans to reduce UK carbon emissions by 78% by 2035, considerably quicker than the originally proposed date of 2050. I suspect that most of the population are completely unaware of the scale of changes needed to achieve this. I cynically suspect that the target will be m...

"instant" hedge

Report from a neighbour, relying on my imperfect memory. They have built nearly 100 meters of almost instant hedge. As follows. 1) With an excavating machine, dig a trench about half a meter deep and half a meter wide. 2) Drive wooden fence posts into the bottom of this trench. 3) Plant suitable bus...

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

If lithium batteries are grossly abused, as in a major impact, they can catch fire.
As can tanks of petrol.

This accident would seem to result from regarding the "driver assist" feature as being "fully automatic" and not be directly related to the power source.

Re: Looks like a potentially severe drought coming

I seem to recall a politician objecting to the water "wasted" by either the CAT funicular or by the Lynton one, he suggested that this "waste" could be reduced by requiring that each passenger going up be required to carry a bucket of water up, this to be tipped into the upper re...

Re: Looks like a potentially severe drought coming

A farming neighbour of mine purchased extra land a few years ago, for grazing beef cattle. The new land is low lying and vulnerable to flooding, hence the low price paid. It makes excellent grazing in the summer or in prolonged dry weather, and has proved a wise purchase. Other friends in North Wale...

Re: New coronavirus in/from China

I expect SOME relaxing of international travel restrictions, followed by an increase in imported infections and the re-imposing of restrictions. And then after everyone has forgotten about the PRESENT pandemic, there will be a new one. The TPTB tend like regulations and restrictions for there own sa...

Re: New coronavirus in/from China

I would say that international travel is now a thing of the past, perhaps I should say international travel made on a whim. Countries (like Brazil) and maybe even whole continents (like Africa or the Indian subcontinent) will now be simply cut off from access to the UK except via quarantine, not in...

Re: Cruachan Hydroelectric Power Station removes F-gas

The black start capability of this power station is indeed most important. AFAIK it has never been called upon in anger, but most important for this facility to be available. Hydroelectric plant is often prefered for black start as very little power is required. Controls, instruments, emergency ligh...
