How far travelling a Hybrid with no petrol

ALL of it.

Nope, Hihe temp and pressure and a lean mixtire has nitrogen 'burning' top make Nox.

Yes.

High temps presures and a superfluity of oxygen due to lean burn

Petrol tems to limit air as well as fuel.

Its still bloody stupid and dengerous.

Hydrogen is the smallets atom there is. It LEAKS. #

The fact that it leaks through steel is an indication of the care required in its usage.

The filling pressure seems to be listed as 35 or 70mpa (10,000 psi) (that is dangerous in and of itself, no matter what the content is.)

The filling stations are extremely expensive to set up too.

Where in the Petroleum (Consolidation) Regulations 2014 are any other current regulation is that requirement ?

The original prius had under 5kWh of capacity or something like that.

One of the so called "plug in hybrids" perhaps.

Also there are a class of EVs where the petrol engine is termed a "range extender"

If the can dodge the ban by installing a pack of AAs and calling it a hybrid, then that would be easier ;-)

Hydrogen is indeed one of the worst gases - hence only it and acetylene being in their own group for explosion risk purposes in industrial installations.

Unlike petrol it does have the saving grace of dissipating rapidly upwards and away instead of forming a liquid pool and a persistent surrounding vapour cloud.

All in all, highly explosive, needing little energy to ignite it, but rapidly dissipated after release.

It leaks fairly slowly and dissipates upwards rapidly. Vents on the top of garages will let it go.

It is however very easy to ignite, needing only a very tiny spark.

If released in a crash it would be extremely explosive and esay to ignite, but on the other hand, unlike petrol, it would drift upwards and not maintain an explosive atmosphere for long.

No, te fundamentali issue is they dont work very well in cars.

Bollocks Tim.

Racing drivers ahve burnt to death because methanol burns with no flame.

Its now fairly banned in the UK

Possibly the DSEAR 2002? There are lots of vague mentions of "guidance" from the fire service at the time that self-service pumps became common, rather then regulations.

Not from Historic Racing it isn't.

Nor from speedway / grass track.

Nor from Drag racing. Top Methanol Funny Car, Top Methanol Dragster

I can't think of any racing class for bikes or cars that was using it and has been stopped from using methanol in the last 30 years.

Seems to be easy to obtain in race fuel grade in UK.

The last supplier also lists dilution ratios for use in production of BioDiesel. You could have a 1000L ICB delivered on your doorstep in a few days, enough to make 5000L of BioDiesel.

But none of those re-fuel with quick fillers and a hot (running?) engine. (Only the Yanks?)

Nitromethane used in "top Fuel" drag racing class and model IC engines ("glow plug") burns to produce Nitric Acid. That's a bit toxic, drivers and fire lane crews wear gas masks.

Natural gas in domestic gas boiler will produce Formaldehyde during warm up. The flame is "quenched" on the cold heat exchanger, the reaction stops with highly toxic part products of combustion.

Many years ago my mum complained about a town gas leak venting from a tubular gate post. A bloke from the gas co came and inspected it. He wasn't bothered as it was vented and not collecting in an enclosed space. With the exception of Hydrogen most gas fuels have to be in an enclosed space to reach explosive mixture, otherwise they just dissipate. Heavier fuel gases like propane will flow along the ground and can then concentrate in drains which can then blow up.

I've driven cars since 1970 and until 2005 never had air conditioning. I didn't miss it, except possibly for one summer day in 1994.

However, since owning a car with a/c I do appreciate it, and can afford to buy a car that has it.

My point is that it isn't really necessary in the UK - unlike a heater. Having said that my father (now long gone) drove cars without heaters until about 1960. I think the mini in 1959 was the first entry-level saloon that had a heater as standard.

In your incorrect opinion. Fortunately that counts for nothing.

A/C is nowhere near as necessary as a heater. My first three cars didn't have it. I *think* my 1993 Mark III Golf had A/C. I know my various Peugeots (306 and 308) have had it.

I managed without until then. There were days when I got into an unbearably hot car and had the blower blowing "cold" (ambient air temperature) air onto me to keep me cool. There were a few days when this wasn't sufficient, especially if I was stuck in a traffic jam and had *only* the blower, without the added ram-jet effect of the car travelling along at 60 mph to force air through the dashboard vents.

When I got a car with A/C it made a tremendous difference. Firstly it kept the car to a bearable temperature on the relatively few scorching hot days. Secondly it dried the air which made it demist the inside of the windows a lot more quickly on cold damp mornings. I used to have to wipe the inside of the windscreen and side windows before it was safe to drive, and they quickly misted up again; now I have A/C, I put the heater on hot with A/C to get hot dry air, which demists the windows and keeps them demisted. Warm dry air is better than hot humid air for doing this (the A/C chills as well as dries the air, and the heater has to overcome the chilling).

A/C is very nice to have, but not essential like a heater is. I've never appreciated a heater more than the freezing cold day that the windows of my

(*) Fortunately when I explained what had happened, the security guys at work let me park right next to their office so they could keep an eye on the car, since it was insecure with the windows open (but the doors dead-locked so they couldn't be opened by anyone who put their hand in through the open window).

Most hydrogen is made from natural gas. Hydrogen is pointless. Every means of manufacture is very inefficient. It's dangerous to store and use.

I asked someone who used to design petrol pumps, his reply ...

"it is a legal requirement, as part of the type approval of the pumps for self-service. Ultimately type approval is only central government guidance to local authorities who have the final say through the issuing of petroleum licences. So the legal instrument covering it is the licence."

Did he mention the Measuring Instruments Directive (EC)?

Did he mention licences being replaced by certificates ?

No, but I suppose neither were applicable back in the 80's when he was designing them ...
