Cars burn fuel. 40% of power gets to back wheels

power stations burn fuel. maybe 55% efficient. lose power from generator to electricicty, stepping power up and down throught the burbs and power line losses. Lose another 20% of input power converting AC to DC for battery.

only saving grace is if car brakes regenerate energy to regain some power spent.

until power is generated by renewable energy, this is Troll environmentalism more than biodiesel.

You're forgetting the type of fuel used though. Cars burn gasoline which has to be refined from oil and is running out in the next couple hundred years. Power stations run on one of three things in most cases. Rivers, coal, and radioactive material. All three of these fuels are more abundant and easier to obtain than oil/gasoline.

There's currently no electric car that can get me from here to my Mom's house without having to charge or change out the battery. I can get there and back on a tank of gas (it'd be cutting it close, but I'd make it).

Even a coal burning power plant produces less emissions for the amount of usable energy than a gasoline-burning car.

Gasoline is a slightly cleaner fuel, but you can't carry sophisticated flue-gas scrubbing equipment in a car, because it's too heavy and expensive. Gasoline, being a mere fraction of oil, is also substantially less abundant.

So, help me out. We're going to use electric cars (which are functionally running on coal in about 90% of America, now) in town, and spend hundreds of thousands of dollars, probably millions, building up a modern train system for our trains (which I believe all run on gasoline) for use out of town?

Meanwhile, we'll be letting the existing infrastructure for highways and gas stations phase out? I guess?

And will a round-trip train ticket ever actually be cheaper than a tank of gas?

It just seems like a whole lot of work that's not saving anybody any money (rather, it will cost an asston for everybody), and (as OP was obviously going for) causes more pollution than it prevents.

And it's more complicated, as I will need two vehicles in order to reach places that I can currently reach with one.

Sort of. A modernized mass transit system would also run off pure electricity though. Granted implementing this on a national scale is a big deal for a nation of this size, but in the end the investment would pay off. Also keep in mind that in our economic system the influx of capital into the electricity market would increase demand for greater efficiency and less pollution as a natural consequence.

The trains run on diesel, actually.

And the plan is to connect all major cities by rail. The design currently being considered for the nationwide build-up project is called the "Anesco." It's a triplewide, meaning three times as wide as your average passenger train. It incorporates various passive and active balance systems as standard, and is quite squat, which makes it very stable, despite the fact that it runs on regulation rails. There are a bunch of models for train cars already worked out. A few vehicle transport cars are planned, which could make it possible for you to take your car with you. The proposed power source is an ultra-compact nuclear reactor, like the ones you can get for individual towns for about 25 million. Obviously, this is going to be extraordinarily expensive and time-consuming, but the deficit's 14 trillion already, so yeah.

You're...kidding, right?

I can't imagine the kind of infrastructure we would need in order to create regularly-spaced power stations for our new train system...and the drain on energy resources would be unfathomable.

At present, we have 200,000 miles of passenger track. Assuming that the trains are twice as efficient as the cars, that's, what, 500 miles per charge? Assuming all our track is in a straight line (lolwut) and that we don't need anymore (LOLWUT), that's 400 power stations that are large enough to accommodate the significant rail traffic you're planning on us having (all of them, since every train running every route will have to stop at every station on its path, for however long it takes to charge a goddamn train)...

Christ, man. The costs associated with this project are going to be ri-fucking-diculous.

I don't think there's going to be a conceivable way that renewable energy sources will be able to handle this power load.

I am going to say this only ONCE this thread so everyone listen the fuck up.

Hybrids, plugins, biodiesel, its all troll bullshit right now. Fuck train network, fuck a a - well, fuck ANYTHING that uses main network electricity or gas.

The only thing that will help the emissions issue, THE ONLY THING, is for all the "greening" money, recources, manpower, and though power to go into doing the folowing two things:

>1. INCREASE THE EFFICIENCY OF ELECTRICAL POWER STORAGE (I.E. BATTERIES) AND POWER GENERATORS (INCLUDING SOALR PANELS)
Both of these advances have been make and are continuing at an off the charts rate in the laboratory due to the use of nano-materials and meta-materials. Mainstream, store-bought (and industrial) solar panels and electrical batteries will be astronomically more efficient within our lifetime.

>2. REPLACE THE WORLD'S ENTIRE POWER GRID WITH SOLAR, WIND, AND NUCLEAR. NO FOSSIL FUELS, NO EXCEPTIONS.
Improve the wires and repeaters while you're at it.

This can be done. For Americans, It could be the great Apollo Project or Hoover Dam of our time - upgrading and greening ("upgreening") the entire power grid, no gimmiks, no troll. Just science.

All this bitchen about batteries leads me to wonder why we don't make inductant roads or conductive tires. You can add additives to tires and make them conductive with out loosing hardly anything strength wise. Or you could use linear motors embedded in the roads because that's probably a little more efficient than induction.

If all the major corredores where powered a 40 mile battery for the side roads should keep almost everyone happy. Direct usage tax would more than pay for the transition, the end result would be cheaper than using gas.

That was just an example. Those 25mil reactors are designed to stay buried in the ground for about a decade, then refueled, then put back. Can you even imagine the safety regulations that come with putting a fucking nuclear engine on a train? If those were still only 25 million I would make sure I stayed about 50 miles from one of these things at all times.

Anyway, you're looking at about 150 per unit, minimum. On the plus side, that will give you a solid 14 years of continuous operation without refueling. Oh, and economic feasibility doesn't matter very much to the government. Take a look at the military budget, Medicare, or even NASA if you want to know what the real priorities are.

geothermal is fucking awesome but badly restricted to only certain areas.

damming is basically like an environmental holocaust wherever it's implemented.

nuclear is definitely the best option. currently rad material storage is taken even more seriously than terrorism, which i'm very happy about. however with large scale use come more slip ups and accidents, and even a small rad leak can be disastrous.

The first sentence is enough to identify OP as an anti-environmentalist troll. Any thermal-cycle engine made from steel has an absolute maximum efficiency of 37% due to the Carnot limit and the melting point of steel. In practice, in internal combustion engine is lucky to get 20%.

> power stations burn fuel. maybe 55% efficient.

It's typically 35-40% for coal, maybe 45% for dual-stage gas. That doesn't include any waste heat utilisation. OTOH, wind, hydro, etc don't consume fuel, so it's hard to ascribe a meaningful efficiency figure (e.g. if a solar plant only converts a small fraction of the solar energy to electricity, it's not like it's wasting valuable sunlight).
