Keyhole Surgery For Gas Mains
I like this story from the Standard, as it shows how good design and clever technology can make the solving of everyday problems, quicker and easier. Here’s the first paragraph.
A £1m robot will today complete work repairing gas mains in London without having to dig a single hole in the street in a UK first that it is claimed will save thousands of hours of disruption to motorists.
It may have cost a lot, but how much did it save?
Should We Embrace Fracking?
As an engineer, I have come to some conclusions about fracking.
There is certainly a lot of gas and possibly oil, buried in the ground, that can be accessed using advanced techniques like fracking in the UK.
Countries like the United States have certainly benefited from fracking with low gas prices and increased manufacturing activity.
There have been problems, as there were in Blackpool in the UK with fracking.
But are we throwing the resources of our great engineering universities, like Newcastle, Surrey, Southampton, Aberdeen, Manchester and Liverpool at the problem? I’ve left out universities that aren’t close to oil and gas reserves.
I doubt it!
Knowing engineering and engineers as I do, I suspect they could come up with better methods, that would benefit the UK and perhaps other countries, who have large difficult gas reserves and are nervous of using fracking and other methods.
So should the major oil and gas companies, be spending a few hundred millions investing in the future?
The Other Upside To Fracking
If you believe that we can successfully solve the problems of extracting gas from the ground using fracking, it should give us enough gas for our needs for many years to come according to reports like this one.
In all of the discussions about fracking, no-one seems to mention how you transform this gas into useful electricity. You put it through an enormous gas turbine engine and this powers some form of electricity generator. Normally these days they work on a principle called combined cycle and you see the term CCGT (combined cycle gas turbine) used. But which British company is involved in this technology? Rolls-Royce is the answer. Unfortunately, their turbines don’t seem to be used in our numerous gas-fired power stations. But I know they could be.
I’ve found this link to a company, I’d never heard of before called Centrax, who integrate Rolls Royce Trent 60 WLE engines into power generation sets. Their web page is here. And this is their page on using the Trent 60 WLE .
So if we have all this gas, will it lead to extra jobs in the manufacturing sector?
It could do if we get it right!
Should We Have Unit Pricing For Energy?
Go back thirty years or more and you paid for what you used with energy. I’m not sure if you paid a standing charge, akin to a telephone line rental, but you knew exactly where you stood. If you used more electricity you paid more money.
Now it is not as simple and to be cynical, I think the energy companies like it that way, as customers find it hard to compare prices.
So when EDF suggests going back to simple pricing, as is stated in this report, do I think it is a good thing?
Of course I do!
But there is something we need even more urgently and that is a smart meter, so we can see how much electricity and gas we are using.
I haven’t seen any reports yet, but a smart meter connected to a smart phone and then linked back to smart heating controls, must save a lot of money. Just think of this simple case. Do you switch your central heating on and off, at the most optimum times. Without information you’re just fishing in the dark.
But I doubt I’ll ever see unit pricing and smart metering, as the energy companies will do all they can to delay its implementation.
A Message For nPower Customers
After my article on nPower’s cheaper tariff, that they hadn’t told me about, I’ve just had a phone call from a friend, who saw it and like me he saved a few hundred pounds by not switching suppliers, but by switching tariffs.
So if like my friend and myself, you get your energy from nPower, it might be worth checking with one of the comparison sites to see if you are getting the best deal. You may find a painless call to the company, will save you money, without changing energy suppliers and hopefully little hassle.
Sorting Out My Energy
Every so often, I check up to see if I’ve got the best energy deal. As some companies are now offering smart meters, I wondered if I could get one of these thrown in.
So I checked one of the comparison sites and found, that I could save four hundred or so a year, by swapping to nPower.
As my current supplier is nPower, I found that strange, as I thought, I was supposed to be on the lowest tariff, according to new government legislation.
So I phoned them up and got changed onto the new tariff. The only downside is that there is now a £60 cancellation fee!
I can’t help thinking, that all of this has a touch of professional theft about it.
I think the moral of this story, is that you should check your energy bills against the rest of the industry probably twice a year.
You might be surprised, as I was, that one short phone call, saves you a few hundred pounds.
I still haven’t got my smart meter though! But then the big companies are reluctant to bring those in, as it will both cost them money for the meter and because savvy customers will cut their energy use.
My Dual Fuel Bill
I seem to pay £154 a month for this.
I wouldn’t know if that is high or low, except that it’s certainly a lot less than I used to pay in the two previous houses.
Smoking Bans Lead To Fall In Asthma
This report on the BBC, says there is a link between the smoking ban and a drop in the number of children admitted to hospital with asthma. Here’s a relevant paragraph.
We increasingly think it’s because people are adopting smoke-free homes when these smoke-free laws are introduced and this is because they see the benefits of smoke-free laws in public places such as restaurants and they increasingly want to adopt them in their home.
I also think, that children are also badgering their parents not to smoke.
When we were developing the metered dose inhaler for drugs, like those for asthma, I came across some research that showed any naked flame in the house increased the oxides of nitrogen in the air, that might be causing asthma. This page from the US EPA outlines the problem and gives advice.
So I would never have a gas cooker or fire in my house. There was one when I bought this house, but I sold it.
Fracking In The Times
The Times yesterday also had an article in favour of fracking from Alice Thomson.
As an engineer and a scientist, I tend to dismiss emotional arguments about anything, when the science and technology says otherwise. In this article, I outlined a few thoughts on the subject. I stated this in the article.
The technologies employed are still very much under development and have been used mainly in the very underpopulated parts of the United States and Canada. The extraction is now moving towards more populous states, like Pennsylvania, and only when it is totally accepted by the inhabitants there, will it be time to use it in Europe.
My views haven’t changed and as I said we should keep a watching brief.
We should also do more research, as I said here.
One point that we forget about onshore energy extraction, is that in Wytch Farm, we have one of the largest onshore oil fields in Europe. It’s also slap bang in beautiful countryside. Do we here a massive movement to close it? To me, it proves that in the UK, the oil and gas industry can be good neighbours.
If we can use fracking safely, I believe that the economics say that our energy bills will drop.
Another Clue In The Mystery Of The Rogue Central Heating
Yesterday, I had a guy from G4S call looking for a Mr. Smith, who supposedly lived in the flat above my house. It was about non-payment of an energy bill to British Gas.
Now, there is no flat above my house, I’ve never dealt with British Gas and the guy said he was looking for a prepayment meter, which doesn’t exist.
So after an amicable discussion, he made a few notes and left.
The whole episode got me thinking. When I moved into this house, some of the wiring was unusual to say the least. So did someone crudely split the house into two separate flats to maximise his income.
This would certainly explain the very dodgy and crude wiring in the heating manifold.
So perhaps, I’m wrong to blame Jerry in this instance, when it appears it was some amateur, who had a possible grudge against me.
