Would liked to have witnessed that.
Here you go:

Thanks :-) How did you do it? Forward or reverse?

Just as you see us - but remember we did have 4WD and low ratio. Can't remember if we used them.

LOL. I've found that the fastest way to bump start a vehicle is in reverse. Never needed more than 5 feet to get a truck started.

The best ever was at TP Cambridge. They had a new Class 2 flatbed delivered & on arrival the driver stalled it & couldn't restart it. Being stuck in the middle of the yard, it was causing issues. Had a word with the FLT driver, jumped in & 5 feet later she was up & running.

The queries I got (being a security guard - took a break from driving due to a fatal accident) were sad :-(

+1 Some fad.

Tesla recently said they are committed to building 10,000 electric vehicle charging stations, here in the US, one is being built near Me, and is almost done, when will the place be done?

I've no idea, could be in October, November, or December, maybe.

In contrast you can use jump leads to start a car with a flat battery, you can also bump start them.

If the car has FI it requires fuel pressure, that requires a working fuel pump which needs electricity so the car won't start with a flat battery, period. A low battery, bump start probably, a flat battery not possible w/o fuel pressure and I also ask where do you get spark w/o the battery?

And a bump start last I looked requires a Manual Transmission.

Alternator.
The Honda CB110 (Super Cub) is fuel injected, electric start. But for those times people leave the key in the ignition & don't turn it off discharging the battery, it's got a kick starter.

Just put the hand crank in and give it a go. Spark magneto. Who needs a battery?

A 1978 Suzuki GS550E had a kick starter too, but I only used it once, just to see if it would work, it did, but I wouldn't recommend using it.

The risk from Hydrogen probably isn't nearly as bad as people think it is. And the fact is Petrol is very dangerous under the right conditions, people have just gotten use to having it around & generally don't realise just how dangerous it can be.


The advantage with hydrogen is that it is lighter than air, unlike petrol, lpg and others. any leak is dispersed into the atmosphere very fast.

Note: - I did not mention safety of using hydrogen as a road fuel. this was quite deliberate.
Many of the issues are much the same as working with any compressed gas in that you have to contain it at all times, have simple but secure filling couplings (much better than those used for LPG please), filling stations have to be usable and accessible. Then there is the energy content of the Hydrogen, it is significantly lower per unit mass or volume than hydrocarbon fuels thus for combustion purposes you need more of it for a given power, and that means a large volume very high pressure tank system. The energy recovery using fuel cells is getting better, but they still tend to be a "fragile" technology, so more work is required to make them realistically robust for use in road/rail transport systems.
One thing that the proponents of hydrogen still have to overcome is the high energy cost of refining it from whatever feedstock you choose. although there are rumours (and have been for a good few years) that a bacterial solution is just round the corner - lab scale production has taken place for a number of years but, for whatever reason, the scaling up to industrial quantities just hasn't taken place.


Got a garage a couple of miles down the road from me, it was used for the first London hydrogen busses, it used wind turbines to generate power to produce hydrogen. The technology used for fueling is now outdated and decommissioned. Better refueling rigs are now out there.

Last year on Radio 4 on one of the science programs someone was saying that the laboratory testing for electricity to hydrogen and then hydrogen back to electricity was achieving over 80% and improving.

you can also bump start them. You can't do that with a 12.5 ton London bus!!
Can't answer that one, but with HGV rigids, it's easy & have done so several times, to the amazement of the youngsters :-)


I have also jump started a few heavies from a car, Its just a case of charging one battery and then boosting the other one.

Interesting that we had this mention of Hydrogen vehicles, because the ABC (Australian Broadcasting Corporation) has a story about Hydrogen cars today.
Hydrogen for cars.
For example, the tank of Toyota's Mirai holds 5 kilograms of compressed hydrogen. The car's range has not been tested in Australia but in Europe it takes about three minutes to refuel a tank, which will last about 550 kilometres.

341.75 miles, that's good.

Then you just have to find a place to refuel:)
It will take many years to resolve the distribution and infrastructure problems before we will see hydrogen vehicles.
But the US Army are trying the Chevrolet ZH2.
Apparently more safe to drive in enemy territories and Green as well:)

I'll pass, I'd rather have an electric car, though where I live at now, can't accommodate an electric car, I'd have to move the manufactured home I live in, but I don't know where to get the money from loans would be nice, but are unaffordable to Me, the land would be pretty easy I'd just need a down payment, it's the teardown, moving, and setup. So I'm stuck here.

Within the UK 14 places now and another 4 on the way.

Whats even more interesting

Installing a hydrogen pump used to require a major rebuild of the forecourt. Now it can be made off-site and delivered in a shipping container on the back of a truck as a completely functioning refuelling station. That’s made it simpler and cheaper to make this technology available.
