Funny you should have posted about FCEVs, and at the time you did. I found out about this company just this morning, was fascinated by the technology and their business plan, and was about to post link at 10:30 this morning. However I ran out of time for my chauffeuring duties, so decided to leave it until later.
Riversimple: UK based Hydrogen Fuel Cell Eco Car Company

I have looked at Hydrogen Fuel Cells for vehicles. There is even a Hydrogen Filling Station near by!

I posted a bit on the Electric Aircraft thread, about Loganair planning to to modify an aircraft, powered by electricity, for use in the Orkney islands. I imaging it will be Hydrogen powered, as Orkney has a glut of cheap Hydrogen from the Tidal generation trials. And for an aircraft, HFC makes a lot of sense.

69 pages and no mention of FCEVs (Fuel Cell Electric Vehicles) ?
I think this would solve many of the problems - if we coud figure out how to produce them.  They are refuelled similar to a petrol/diesel, so nice and quick.  The taxman can get in on the act. The H2 can be produced by the filling station as and when the electric grid can supply the load. People without driveway parking or garages ( i.e. most car users) can use the technology.
I don't know how reliable the fuel cells are ? or how long they last - but they must be better than producing all those batteries. I think FCEVs are significantly lighter than BEVs - comparable to current gasoline powered cars.
I know the filling stations can be expensive - but would that still be true if they were as common as petrol/diesel/LPG outlets ?

By the time you have used electricity that could be used to charge a BEV directly to make hydrogen (not very efficient) and then have the efficiency (they are pretty efficient but produce a lot of waste heat and run at very high temp) of the fuel cell you have probably not used energy wisely.  Add to that the problem of storing Hydrogen at high pressure at the filling station and  in a vehicle it becomes a bit of a nonsense.   They are lighter than a BEV though,  but fuel cell vehicles have been around for a long time and never caught on ( maybe caught fire though).   Sales of BEV actually peaked in mid 2017 and have been dropping since,  but so have sales of normal vehicles.

The inability for governments to levy tax on electricity used to charge vehicles will mean that GPS tracking and road pricing is inevitable ( at least UK may have their own GPS system by then and not the EU one - they have kicked out a major contributor and their main contractor,  suddenly UK have become 'the enemy' and are not to be trusted LOL).

In my experience 99% of electrical engineers don't have an oscilloscope in their tool box, but it you have it, why not use it. Scopes have come a long way from what I cut my teeth on.

That looks great. I am not so sure about the interior but it certainly looks "different", and well executed.

Different marque, but what about this? Believe it or not, but my daughter bought this, brand new, from SEAT. Just as you see here.

I don't know why others think the oscilloscope is so difficult - It's not much much bigger than a DVM, and I just clip it onto the battery terminals - it just gives me a display relative to time and lets me measure voltage drops etc, I can use the headlights & HRW to add to the load.  The test didn't show any problem, probably because the engine fires up immediately.
I don't use the interior lights anymore

99% of normal people don't have a oscilloscope in their toolbox - I used to use them for catching transient events and complex waveforms, but for checking car battery voltage drop, nahhhh ! If I had paid for one and was looking to use it, maybe - but IMHO bit of an overkill.

Looking good.
It's nice to see a modded Jazz on the forum--I think this is only third one I can remember seeing .
Well done ! 8)

Hello Jocko.  I agree - a car battery should be able to handle that sort of use without any problems.  Perhaps the Jazz protected the battery from too much current drain, the locks all worked, the dash lights came on, but the mult-information display didn't, and the engine wouldn't turn over.  The battery appears to have recovered without any problems, and the car starts easily after being left for several days.
