More Car Charging Juice Needed Humphrey? Yes Minister.

I looked for a short video of the Heads of the Valleys road upgraded. 


Road building in Wales is nothing like in the Midlands or East of England, the height the ground is being raised in places is phenomenal. Here is the official visualisation   this hand held camera video gives a real idea of what is going on.


So at a time where people have been allowed to stand in roads stopping vehicles stopping people and goods from moving around the towns and cities there is actually in reality some huge infrastructure projects improving the road network to move goods and people across the whole of European, but the EV car chargers are away from the road the a supermarket car park.


So will battery technology improve enough for long distance journeys in an EV or will people use an alternative vehicle or other means of transport to the one they use on a daily basis?

"Is hydrogen really difficult to make, store and use?" Anyone got an up to date copy of the BS for the use of electricity in potentially flammable atmospheres?

My recollection was that if hydrogen might be present don't use ectricity was the recommendation in summary.

I just about remember the conversation from town to natural gas we had a gas fire in the dinning room and a bloke from the gas board came and adjusted it and I think to the meter as well but can't swear to that. In an earlier post it was said coal gas had carbon monoxide in it is that right? Is it flammable and how did it get there since I thought it was a result of incorrect burning but the gas is t burnt yet when it's in the pipe  so how did the carbon monoxide get there

Well I guess we will have to scrap all those battery rooms stacked with lead acid batteries for emergency services on ships and in some buildings, etc.  That a shame as we have used them for decades without that many problems.  I suppose I will have to dump the ones on my yacht too.


A spark near a gassing lead acid battery tends to blow the filler caps up in the air with a big bang but not much else,  at least that is what happened when I played the idiot and moved a connection on a gassing battery bank.


However, to balance the negative comments  against a hydrogen solution try these:

Hydrogen may or may not be part of the solution.  However, I fail to see how the current electric cars with all of the the problems of providing suitable infrastructure will be a long term answer.

Hi Kelly


Yes coal gas was a mixture of several gases. The first was from distilled solid coal in externally heated closed retorts, largely hydrocarbons of various types. The leftover coke was then subjected to two processes, one exothermic (giving out heat) which further heated the hot coke by blowing air through it to partially burn it producing carbon monoxide, and then blowing steam through the hot coke, cooling it in the process, making "water gas" which was a mixture of CO2 and hydrogen. The CO2 was removed with lime, leaving a good inflammable mixture although very poisonous. A nasty smell was added to warn you of escapes.  It was distributed at very low pressure, so leakage of the hydrogen was not too serious, but there were sometimes explosions, probably because hydrogen in air ignites very easily from any size of spark or even hot surfaces.

Try here water gas

EU funded roads - whilst I have travelled on some of them, I have never found one in England, not that that matters any more.


Bristol ... last time I went there I had the cunning plan of parking at the Parkway station, but soon found that it is not as conveniently situated as Southampton Parkway. So we paid and parked, went down to the station and found that all trains were cancelled! I once took a wrong turning in Bristol and had to go about a mile and a half before I could turn round. Not at all vehicle friendly and it is difficult to see how an EV would do any better.


Supermarket charging ... average time spent in store = 45 min. So a couple of kWh from a standard charger = 10 miles. It doesn't sound like much, but it may pay for the round trip and will certainly attract customers - rather like cut-price petrol.

It would appear that Andy B has discovered that Greggs, Costa and a min supermarket take precedence on  EV charging.


As for EU money we have been giving the EU shed loads of money a chunk is creamed off and some of it comes back as EU grants but are told how and what we are allowed to spend it on. It's our own money not the EUs but not for much longer we will be part of the EUs Ponzi scheme.

The key difference between the old gas supply with a mix of H2 and CO and now is that there were also trace amounts of various tars which sealed any holed in the pipework.

Now with gas coming to the UK as LPG carried by giant carriers there isn't any tar so small holes don't get sealed.

In an earlier post it was said coal gas had carbon monoxide in it is that right? Is it flammable and how did it get there since I thought it was a result of incorrect burning but the gas is t burnt yet when it's in the pipe  so how did the carbon monoxide get there

As Dave said, town gas is the result of partly burning coal - in the days when the gas works really was a works, not just the site of a big gasometer.
