As there are a few nuclear power plants in Korea, these are partially powered by nuclear power. I would like to see these buses have ZEBRA batteries in them, but one must use the home industries. They should also have had some fuel powered range extender like the capstone turbines mentioned in the next article. ..HG..

An excellent solution that will get to be better very shortly as batteries performance improves.

A hand to Seoul and Hyundai.

A small low cost emergency e-range extender on a $800K e-city bus would not be a luxury nor much of an extra cost. A small 10 Kwh FC or equivalent ICE genset could keep the electric ancillaries working during extended traffic jams and help this e-bus crawl to the next high speed charging station.

It may be an option?

Circulators are a neglected form of transit. Most US transit fleets consist entirely of 40' high capacity buses designed for (crush load) rush hour commuters. Circulators run short routes where demand is consistent throughout the day, but not rush hour level; a situation which requires high frequency. The short route circulator requires the least number of buses/trams to meet the demand for high frequency. They need not be high capacity nor built to reach highway speeds. The shorter, lighter 35' model bus is more navigable in tight urban settings.

This realy requires the ability to gather up huge numbers of people in very dense patterns. Something you realy only see in countries with 1 megacity and a rich country at that.

The us has no megacities.

'This realy requires the ability to gather up huge numbers of people in very dense patterns. Something you realy only see in countries with 1 megacity and a rich country at that.'

I've got no idea where you get that idea from, but it is quite erroneous.
There are umpteen cities in Europe where they will work fine for a start.
I don't think places like Norway or Belgium have any megacities.
I am not so sure about the US.

Davemart a megacity is like tokyo or seoul or mexico city or such.. a single city that alot of that countries efforts goes into. La isnt dense nothing lile a true megacity. Look up pop density of cities around the world.. its just gobsmacking how dense some places realy are compared to what americans think is dense.

If a 2 mile long line can only catch 100 people it wont work.. if it can catch 10000.... 50000.. oh boy.

@wintermane:
I am aware of what a megacity is.
You argue that mass transit does not work except, for some strange reason, in countries which have a megacity.
I can't conceive why you should think that to be the case, as buses etc operate locally, not so much nationally.
In any case it is entirely misconceived, as mass transport operates fine in many countries without a megacity, providing the local population density is high enough.
It is true that they often need subsidy, but that is because private cars are not fully charged for the road space they use.
Most European cities would be permanently gridlocked if everyone used their car instead of a bus or tube.

@mahonj,
Buses run on routes which are highly predictable, and so can be specified accordingly.
As long as it's route is within the capacity of the battery, or in the case of the Proterra have sufficient charging opportunities for their quick charge battery, adding a RE only increases cost, including importantly maintenance due to the additional complexity.
One of the major advantages of pure electric vehicles is their very low maintenance.
There is though a case to be made for the provision of non-electric heating, so that if the bus is stuck in traffic it can still complete it's route.
Unlike putting a RE into the drivetrain the cost is modest and more than paid for by the increased reliability.

I'm not sure why people are so obsessed with range extenders. Obviously this vehicle is designed to work as intended with batteries only. Since it can do that, adding more cost and complexity with an unnecessary range extender makes no sense at all. Makes about as much sense as putting an extra gas tank in your car so you can go 1000 miles on one fill up, it serves no purpose.

Since we have CNG diesel buses now, why not CNG diesel hybrid? I don't know about battery life when you draw huge currents for take off, but super capacitors could help.

I seems like there are a lot of configurations to help that don't cost a lot. The most bang for the buck when transit bus budgets are tight and states are running deficits.

Thats a case where your going from a station to the state capital of course there are alot of people going from there to there. Thats realy no different then a bus going from airport to a nearby train station.. which begs the question why wasnt the staion put in walking diatance of the capital grounds.

"RP3 has probably never seen our snowy days downtown traffic jams when city buses can move less than one mile an hour."

So let's see, our EV bus is sitting around doing nothing for an hour. Let's say it's operating 500W worth of lighting, and 200W of onboard computers and systems. So in that hour it consumes 0.7kWh of energy to run lights and systems. Out of a 102 kWh battery. Unless you're stuck for several days, I really don't see the problem.

Heating, as others have said, should be done with a fuel-fired heater, not with electricity (unless you have a good air-source heat pump).

Wintermane, your "That's a case of going from Union Station to state capital for a lot of people - really no different than from an airport to a train station - which begs the question why wasn't the station put in walking diatance of the capital grounds?" is a simplification that won't stand.

For the first 20 years, the shuttle was a 1/4 mile short of Union Station, and at the other end it's still short of capital buildings by 1/2 mile. 16th Street traverses central downtown Denver, busy enough but not high density. The shuttle serves people all day, not just twice daily train passengers. It keeps peripheral bus lines, their noise and fumes, out of this main downtown district.

Major railroads require separate ROWs. They can't and shouldn't run directly to important destinations like Capital buildings. Connectors/circulators/shuttles serve as transfer systems. Big city transit system design must integrate transfers between bus/bus and rail. Circulators can make the best transfer system because the time waiting for unavoidable transfers is minimal, they require the smallest fleet, and the vehicle can be designed specific to purpose.
