Electric buses.

https://www.bloomberg.com/news/artic...e-oil-industry

About 279,000 barrels a day of fuel won’t be needed this year

The numbers are staggering. China had about 99 percent of the 385,000 electric buses on the roads worldwide in 2017, accounting for 17 percent of the country’s entire fleet. Every five weeks, Chinese cities add 9,500 of the zero-emissions transporters—the equivalent of London’s entire working fleet, according Bloomberg New Energy Finance.

Anything that doesn't sound like it has a Gardner under the cowl is a shoebox on wheels.

note the handy banners letting the citizens know what season it is.

A good idea those seasonal banners. Sometimes impossible to tell which season it is
here without.

Dawn is breaking here as I type and the racket from the birdie chorus is wonderful.
Looks like we are in for a least a pleasant morning as well.

Having an angiogram done this afternoon. Another excuse to punch a hole in my body.

Good luck with that. Had mine 15 years ago and it saved my life.

I mostly agree with your sentiment, but this bus has an AEC motor. I think the only deckers we had with Gardners were a small batch of prewar Albions. Here's our AEC on its first night out after restoration:

Either they have tinkered with the colours on this site or I am going blind. Anyway, is that right, 9500 new electric busses in China every 5 weeks with 385000 busses? I need to adjust my sense of scale.

I don't own this space under my name. I should have leased it while I still could

So why did we do away with teams and trolley buses in the 50s.(1937 in Birkenhead).

Just a thought, I wonder if it was part of Cold War Civil Defence policy as trolley buses would be wholly dependent on fixed infrastructure whereas diesel buses would be potentially more flexible.

I used to fly over the BYD factory in Shenzhen when they first started about twenty years ago. They started with petrol engine vehicles for short time and then went electric. Not only are all the buses in Shenzhen electric but most of their taxis are too. This has all been enabled by the nuclear power station built near Shenzhen which supplies Shenzhen, half of Guangzhou and Hong Kong.

For many years Chinese buses carried a huge billowing gas balloon on the roof.

I can remember those at Luzhao in the 90s. Then they changed to LPG.

The same during WWII in Manchester

Why hasn't GB caught onto changing our diesel buses for electric. There must be a technical or operational reason, surely?

Zero emissions? I wonder where they get the electricity from?

Just a pity about the hundreds of power stations they're building every year to power them.......

From Wiki.

As of March 2018, the People's Republic of China has 38 nuclear reactors operating with a capacity of 34.5 GW and 18 under construction with a capacity of 21 GW

It matters not how large the carbon foot print is to produce the materials to make the electric cars/busses/bikes, wind farms or solar panels, or to transport them to the assembly plants/locations, neither does the source of electricity to power electric vehicles, or for that matter servicing them and finally disposing of said items once past their sell by date, it only matters that the greens see they are achieving an end state of zero emission vehicles, it makes them feel all good, regardless of the final cost financially as they are rather expensive currently.

I think we still had trolley buses into the 1950's and 60's, as I have distant memories of seeing them in High Wycombe, when staying with my grandmother as a small boy. I have a feeling that they were phased out because of the limitations of all the overhead cables they required. As a small boy I remember seeing a trolley bus stuck in the middle of the road because the power collecting rods had become detached from the cable, and the driver was using a long pole to try and hook the things back on to the overhead cables. Not sure if this was a one-off, or a regular problem with them. Maintaining all those overhead cables must have cost a fair bit too, as well as impose a lot of restrictions on the other services that wanted to sling cables along and across roads.

The odd thing seems to be that we phased out electric trams and trolley buses around the same time as we were being promised free electricity in the future, thanks to nuclear power.

Well, gotta cut down that smog somehow. Electric buses replace all those spewing ground level exhaust pipes with very tall coal power station exhaust chimneys. This relocates the pollution from your ankles to somewhere up high where the winds will carry it far enough to be someone else's problem - maybe.
Most of our urban buses have always been electric trolleys with diesels running the suburban routes. There are some plans for a trial of pure electrics (Chinese buses as it happens)(not like we've not trialed electrics before, and hydrogen.) Problems have been our hills, their ranges, ranges under heavy loads, dependability and re-charging. New one's are supposed to re-charge wirelessly from some under-pavement system. We'll see.

(China is the largest producer and consumer of coal in the world, and is the largest user of coal-derived electricity, generating 3959 trillion watt-hours per year, or 74% of its electricity from coal as of 2014.)
But, it is trending down slowly.

Newcastle trolleybuses were withdrawn October 1966.
Replacing the overhead arms onto the wires was a standard occurrence - the long pole was stored under the bus.

Yes - what happened to free electricity?

Power collection poles are now attached by rope from the head end to two tensioned, ratcheted reels on the back of the bus. The reels pull the poles down about halfway from the wires if there is a disconnect. The operator then can re-attach the poles by manipulating the ropes. No extra pole required.

Free electricity is right there - beside the free lunch.
