Toyota mirai hydrogen fuel cell car is it the future?

Nitrogen is a gas. It doesn't react with anything in this instance, just gets released back into the atmosphere. It's not a pollutant either as air contains 78% nitrogen already. Hydrogen is what produces water.

 

That's what my wife tells me when she's losing ground

 

Doesn’t liquid nitrogen turn into nitrogen gas that also reduce oxygen levels.

 

I thought it was more like 'can we find anything at all to justify investing a shed load of money to provide a load of nearly useless 100 metre range base stations'.

I would rather use some radars and a direct vehicle to vehicle link rather than hoping that the vehicles at the front of the train are still even in range of a 5G base station, as those at the back pass it. I expect 5G bandwidth will get mostly used up handling hand over from cell to cell every couple of seconds for millions of vehicles..

We were looking at using 2G back in the 1980's in the EU DRIVE program . Nobody ever did it, and that has a range of 35km on a good day.,

Our most creative thing was putting an antenna on a lamp post with a RF network analyser connected, then tying 100 metres of aerial cable from the analyser to the lamp post and the other end to a Ford Granada with a cellular phone antenna on the roof, as it was in those days, then driving from about 100 metres away from the lamp post to 100 metres the other way as somebody shouted "STOP" before the cable snapped. We then got a direct measurement of the signal loss between a pico cell base station and a moving vehicle.

 

I’m just gonna keep driving my gas-guzzling inefficient old petrol internal combustion engined bangers until I’m not allowed to anymore or they’re taxed out of existence.
By which time I’m sure the economic drivers of the car industry (‘scuse the pun) will have decided what propulsion system is best for them and complies with whatever the reigning government at the time decrees.
Seeing as they all told us that diesel was clean and incentivized the market to buy into that blatantly obvious myth I’m not confident that it will necessarily be the right choice.

We’ll see. If I live that long.

In the mean time I’ve seen studies suggesting that a new car takes between 3 and 9 years worth of average fuel consumption energy equivalent to manufacture depending on the energy source used to generate electricity, so that offsets my energy footprint by not changing my car every 5 years. I reckon...

Pollution might be a different matter though, but seeing as I’m polluting the countryside not the city they don’t care so much about that.

Ps. I expect that super-capacitors will play an increasing role in electric vehicles as the technology develops and since the motor industry seems committed to going the electric route.
They’re safer than batteries, charge a heck of a lot faster and are less resource intensive, but they’re better at short term power delivery at present.

PPS I’m no expert so that’s probably all wrong. Every bit of it.

Dunno about wifi drafting of big vehicles, and an air gap, as the wifi might stop, so...splatttt! How about a physical chain and hook link? Get enough and you have a road train.

even better how about just driving onto a train with your car, efficient as hell..then drive off at the end so you can break down in Cornwall, or even better...in France all on your own without the long drive down...why didn’t anybody ever think of that?

 

i think they do have road trains in some place - Aus maybe? works fine if every unit is going to the same place.. but you lose the efficiency if you have to stop everytime someone wants to leave the train?

They used to have exactly this in France a few years back but i think it's stopped now - drive your car on to a train in calais, sleep in a sleeping compartment as the train travels overnight to the south of france, wake up for croissants on the coast d'azure

 

And all the loose bits removed as your car is dragged backwards at 100mph through the air on a flat truck..

 

We had a fun ride in the camper on an open train through the mountains in Switzerland. Not very far but it saved a long drive over the top.

 

This is the one that ends up at Thunersee and Interlaken if you're going north. We did this about 5 years ago. Not my video BTW, I just stole it off YouTube.
