Yeah So...
I've got the other blog http://ORIFLeftLeg.blogspot.com which is talks about my accident and recovery etc. I've got my flickr (www.flickr.com/photos/squareoftheyear) where I put my photos (e-mail if you want to buy usage rights)AND I've got a YouTube channel SquareoftheyearFM where I sometimes put things but not with any level of regularity.
I shall post here again at some point but I'm not sure what it'll be, when it'll be or whether it'll be worth reading.
Take Care

Energy distribution…
During my various pieces you’ll hear me arguing about the distribution of power to electric vehicles. All of the big players in this industry recognise that oil will not last forever and that we need to find an alternative. Annoyingly it looks like the worlds supply of oil will last until the people that run these companies retire so they have little interest in pursuing alternatives but to play lip-service to it.
There have been several alternatives the most successful of which of late has been LPG (liquid petroleum gas or butane/propane mix to our American friends), this fuel does come from oil but it’s normally wasted so by bottling it up it was seen as a way of prolonging the supply. Its not as efficient as petrol but it’s half the price and a normal petrol engine can normally be made to run on it. People rushed to convert their thirsty cars and Vauxhall even produced new cars with built in LPG tanks to take advantage (Duel-fuel cars benefiting from certain tax cuts here in the
Then diesel vehicles began to take off (yes
So we’re left with ‘alternative propulsion’ fuels which at the minute are; Hydrogen; Compressed air; and Electricity.
Compressed air in my own mind is nothing other than a curiosity. You compress air and store it in a cylinder; to convert it to drive you pass the air through a three stage motor that drives a high-pressure, a medium pressure and then a low pressure piston. The rest of the drivetrain is fairly conventional. Another way of providing the compressed air is to produce steam but then we’re getting into the realms of steam cars again (see below).
Hydrogen is an interesting one. You can extract Hydrogen from gas by steaming it or by electrolysis of water. You can then either use the hydrogen like the compressed gas option or by using a hydrogen fuel cell which re-combines hydrogen with oxygen and gives you electricity and water. This electricity is then used to drive an all electric drivetrain. I’m led to believe that this is a fairly efficient process and it has the benefits of instant fill ups and the only emissions are water. I say efficient, the turning hydrogen to water and getting energy out is efficient. Creating hydrogen isn’t very efficient, its storage isn’t very efficient and its distribution doesn’t exist as yet. Currently the storage on board is a bit of a sore point as the pressures involved restrict the tank size and range.
Advocates of hydrogen claim that the production could become more ecologically sound through the use of nuclear, wind, tidal power stations etc. which is true but the government would have to do something about it and we all know they’re too tied up with expenses and immigration to care about the environment or science. So whilst hydrogen IS an interesting prospect I don’t see it as anything other than an interesting taster of what the future could be.
The final option as far as I see is electric vehicles. I’m going to admit now; I’m very much an advocate of pure electric propulsion but stick with me.
When cars were first making it big there were steam, petrol and electric cars. Steam was smelly and required a lot of work, electric was limited to the battery technology and people didn’t trust driving around in a vehicle full of explosives but somewhere along the way petrol won out. In the
My feeling is that supermarkets, service stations and large employers are the people who could push this. Whilst charging at home on a single phase supply might take eight hours, a three-phase supply could provide 80% charge to most EV’s in as little as half an hour. These places already have three phase supplies and even if they needed to upgrade the incoming supply to take account of the higher peak draw it could be quantified and used to decide on how much to charge per unit of electricity.
Car manufacturers don’t seem interested in making the leap, there’s little incentive for business to make any investment if there aren’t vehicles to use the infrastructure.
So what’s needed? It goes against my very nature but I think business should be encouraged to work towards electric vehicles for everyday use, based on existing vehicles. Toyota did it with the Rav4EV and Ford did it with the Ranger SUV, both were done in the 90’s, almost twenty years later what’s to stop them outfitting some of their cars with lithium-iron-phosphate (as opposed to lithium-ion) batteries and a propulsion system based on one of the hundreds of smaller manufacturers who’ve perfected the technology?
God forbid another NGO come along and tell people what to do, but the big manufacturers had floundered long enough. GM have had the technology to produce effective EV’s for twenty years and all they’ve done is throw it away and start again to make it look like they’re doing something.
Maybe the stepping stone we need are hybrids but I’m sceptical as to whether the car makers are using it as a development of future vehicles or as a way of prolonging the old technologies.
How do we solve a problem like electric cars?

GM decide not to sell Opel/Vauxhall
Okay, so I for one was over the moon when the sale of Opel to Canadian parts manufacturer Magna International Inc. Magna had shown a rare vision in modern automotive companies, it wants to promote electric vehicles (EV’s). Magna International had already developed EV technology and were buying one of
Then comes the news yesterday that GM have made more money than they were expecting, US Taxpayers money, and to celebrate GM decided to pull the sale of Opel/Vauxhall. Ordinarily that would seem like good news but Magna had already been in discussions with the unions, had already worked out a way to make the business work after GM had let things get so bad. Now we’ve got GM playing the jealous older sibling “its mine hands off!” “you’re not having Opel/Vauxhall, I want them”. This leaves the staff unsure again what’s going to happen to their jobs, it means a stagnation of vehicle development and the prospect that we may have a version of the Chevy Volt thrust on us.
Don’t get me wrong the Chevy Volt IS a step in the right direction, it’s a 1.4litre hybrid, not a million miles from the old Toyota Prius, but that’s the point, the OLD prius. The new Prius comes with a bigger more efficient engine, it’ll come with a plug soon so you can plug it in boosting your mpg’s to around 150, still nowhere near the efficiency of a true battery electric vehicle but much better than what GM are promising.
That’s what’s going to happen, the Volt will be released with great fanfare but it’ll be released to a world where cars have already moved on. Toyota are miles ahead promising hybrid versions of all it’s cars, Honda have a couple of great cars, Magna Steyr are already developing their own car, Tesla have grasped the publics attention with their sports cars, Smith Electric have developed an EV version of the Ford Tourneo Connect, Ford may eventually bite the bullet and market a version of the focus with either a Magna or Smith drivetrain and Renault have already made a lot noise about the four new EV models they will be releasing soon.
So what of Opel/Vauxhall, well what we’ve got left is European arm of GM who were almost in a position to come out of the darkness and become world leaders in mass produced electric vehicles gobbled back into the arms of the company that destroyed it’s own EV programme for Hummers about ten years ago. What can we expect as the next move? I’m not sure but I’m guessing GM will find a way of stuffing the Volt project up somehow, Ford will flounder a bit longer and the smaller manufacturers will struggle to get enough interest to make the economies needed to get the price low enough to compete with mass produced oil burning vehicles we’ve become so used to.
