Ten years to go until electric...

Hi all

To be honest the electric vehicle my cut down pollution locally but as for global warming it will make no impact what so ever

Got a chance to be on the flight deck of a 777 during a business flight to America before 9/11 and they asked what do you think we are doing miles per gallon and the 777 burns thru a ton of fuel ever 10 mins

(For that flight (Gatwick to Dever) total fuel used was about 50 tons)

Just picture that for a moment that’s a ton of fuel  ever ten min for just 1 plane

So if you want to have any impact then  non essential air travel has to go as this form
of transportation is one of the world biggest polluter / generators of CO2 plus China India and the USA with general CO2 output

But I thing the biggest elephant in the room question is uncontrollable population growth

Unfortunately I think it’s all a bit too little / late and the human race is now on borrowed time and Mother Nature at some point will reset the clock

Rant over

Best wishes Al

Surely SumpMagnet, the generation of more (electrical) energy will be totally offset (+ more) by the reduction of fossil fuel requirements for those same cars? A modern ICE car is 20-35% efficient in converting petrol into motive force; whereas an EV is 55-70% converting power station to motive. But if it’s battery is charged / offset by personal solar panels (we mostly have our own roofs) the efficiencies just get better....

As for your thoughts on efficient m/cs being the future; yep it makes sense to this forum. But alas Joe Public by-and-large wants 4 wheeled chariots / protection from the weather & idiot road users ... so I guess that one won’t fly 🙁.

My gut feeling is we’re back in the late 1800s, where horses were the only way, and the new fangled Otto cycle car thingy was completely laughable due its massive ferrous material demands, combustible liquid requirements, and complete lack of infrastructure. We’ve been here before... it’s no different.

Personally, I’m bloody amazed that a backward reciprocating engine & its support systems with hundreds of moving parts had survived into the 21st century... when an EV has abouts 20 moving parts.  What gives eh?

Al... I’m retired now, but flew long haul for a living, B757, B767, B777 & B787.

All very ball park...

The B777 does indeed burn around 6T/hr, but for that you get to transport 300 folk, plus a few tonnes of cargo at 550mph.

Let’s say that’s 150 typical car loads, each car using 40kg of fuel, or 12 (Imp) gallons.
... meaning, that on 12 gallons each car takes you 550miles, achieving 45mpg.

Generally cars have one occupant, few have 4. Aircraft generally fly close to full... and as such, are arguably (person for person) kinder to the atmosphere. Certainly, I don’t believe, they deserve any more stick than the personal ICE automobile.

I do agree however on overpopulation!

But that’s the problem

The electric car is not the fix it’s a total move away from burning fossil fuel for the human race end off

(And not going nuclear either as thats not green or renewable)

As for planes the problem is the CO2 is dumped at high altitude and that is where it stays so maybe not as kind as it looks

It’s interesting that just after 9/11 air travel in the states was halted and due to no flight and therefore on con trails the actual average temp at ground level was measure to increase by at least 1 degree as the con trails reflect the sun heat back out into space so basically I think we are screwed stop flying the CO2 is reduced but the temp increases anyway due to no con trails

What it is doing and will continue to do in this country is to penalize the poorer end of society. Why should those who can afford and want to buy new EVs be sponsored by by the less well off.
