Another problem with LPG is the metering of the fuel, if it’s right it great, but it can be hard to set up and because it is a conversion it is not necessary tuned to that specific engine.

So true - would you trust this government????

They are already saying "the environmental advantages of LPG are now much smaller due to the advances in modern engines" - in other words they do not consider them to be cleaner anymore - yes of course so they must be taxed like petrol - the fact so many people are now using them has NOTHING to do with it of course!

Still they des[erately need the tax to fund wars in Iraq to make us safer and to put speed humps and camera everywhere to again make us safer - I am so happy to be looked after like this.

It is great also to be stopped from kite surfing - caving - mountain climbing and doing any other stupid activity where I may hurt myself!

What is it with this country - all they want to do is BAN things - like flares when some idiot killed somebody with one - the flare used was a parachute rocket - they banned small hand held multishot units..........


Sorry rant over!

When I said oil will NEVER run out I stick by that - if you doubters had read exactly what I said then they would see that it would get to the stage where it is uneconomical to obtain.

Think of gold - obviously there is a finite supply in theory but in practice we will NEVER find it all - it will just go up in price as it starts to get rarer.

It is a bit like needles off a Christmas tree - no matter how many you remove more always turn up!

As to getting hold of petrol at 14p a litre - easy - all we have to do is get a flotilla of ribs - go to Rotterdam and buy off the spot market - fill the tanks and even the tubes and tow all the boats home.............

Which flares have been banned? As far as I know miniflare packs are still available.

John the ban he is refering to is not the mini flares with a stick as the trigger but a hand held widget working like a revolver with about 6 shots. They could be aimed and fired horrizontally. Water proof (ish) they were popular with divers a few years ago until removed from the market because they were an effective firearm.

Being a Ribnet Rebel of course I still have one ready for the next paint ball experience.

Ah, I know the ones you mean. I have seen them on the continent but I hadn't realised that they were ever available in the UK. Live and learn!

Yes they were popular with winsurfers and climbers as well. Although they were multishot they were nowhere near as powerful as a proper parachute rocket.

The bloke who was killed would still be here today if one of these had been fired at him instead but of course they had to BAN something..........

I used biodiesel made from soy oil for the circumnavigation I did in a RIB a few years ago. I used 100% for nearly all the 35k miles, mixing with conventional diesel rarely (when someone "misplaced" the fuel). It doesn't smoke, doesn't stink, is good for your hands, ensures a clean and odor free bilge, and the exhaust smells like cooking oil - because it is. The cetane rating and lubricity are both higher than petroleum diesel, particulate emissions are reduced by 30% or more, its biodegradable, renewable, and is really a pleasant change from working with diesel fumes over the transom. It can be used in any diesel engine without modification and can be splashed blended with whatever is in your tank, in any proportion. That's not true, of course, of raw vegetable oil - the fats will eventually cause problems if not treated in some way.

In the US its manufactured from both raw seed and from used oil. I'm in Hawaii at the moment and there is a company here which collects the used oil, processes it, and sells it as fuel (Pacific Biodiesel). Anyone wanting further info can find it all at www.biodiesel.org.

wish it was less expensive!

It is technically possible to run a diesel engine on LPG, there are several large commercial vessels running using this system. They use a modified injector, which has a ring of ports around the diesel injector. Once the engine is running the diesel fuel is isolated at the pump and an electronic management system injects liquid LPG at high pressure through electronic injectors. Speaking to Wartsila engineers who seem to have the system running quite well it seems to be quite good.
I don't know if this will ever be relevant for automotive sized engines, as the cost of having 2 injection systems will be prohibitive when gas at low pressure can readily be burnt in a petrol engine.
What about fuel cells for boats!
