2. Yes, in international shipping, corners will be cut. Oh, and convincing shipping companies to replace their fleets, or have a portion of their fleet in drydock for engine replacement, will not make them happy.
I wouldn't have to do anything of the sort, soaring fossil fuel prices will do that for me.
To that I respond with this. A little supplementary sail that can help move freighters along.
That is disingenuous to the point. For one thing that is supplementary, but to suggest we should take the back to the future approach and go with wind ignores the reasons we stopped using it in the first place for anything other than recreation, namely low energy density and unreliability.
No, not at all. Thanks for misinterpreting my point and ranting about antinuclear conspiracies.
Conspiracies? There was a major anti riot action in your own country
two days ago over this. You call that a conspiracy? In America there are groups like Greenpeace or the Sierra Club that go around the country
scaring people with information that has been debunked over and over. Anti-nuclearism is a very real ideology, yes an ideology, because
it has everything to do with an inability to seriously confront criticism and
nothing to do with science. It's politics, plain and simple. To give some idea as to why exactly the evironmentalist policies are bad, read
this.My point is, why try to make a small nuclear plant and try to power small stuff with it, when you can build big power plants, and use the power generated in them to charge batteries, or run hydrogen extractors for fuel cells? Way I see it, small power plants just aren't as efficient as the big ones, while bringing with them an entire host of engineering problems. Wouldn't it be easier, cheaper, and more efficient to skip all those issues?
No, it would certainly not be cheaper and it would be dramatically less efficient. A vehicle like the one posted requires several megawatts of power, meaning your batteries would be huge. It is reasonable to expect battery energy density to increase ten fold in the coming decade and the slow charging problem will be elminated, there are still some very serious problems with batteries wearing out and needing to be replaced wholesale. To power the space station for the whopping 35 minutes it is in earth's shadow it takes several tons of batteries and all of them need to be replaced every 6 years. It would be significantly less expensive to ship the reactor module back to the factory, exchange its fuel rods, and ship it back to the site than it would be to put in new batteries, by a large margin. Hydrogen has very serious, very fundemental
problems that will not likely be resolved, and even if they were somehow, by that time there would still be a better alternative.
i don't think nuclear power scales as well as you think it does. it's not a question of power output, of course you can always run less. it's a question of physical size. there is a LOT of hardware required to make a nuclear reactor work. you need the vessel, pumps, control elements, turbines, piping, steam generators, shielding... shall i go on?
No need to go on, read about this suitcase sized reactor instead.the tiny little 1MW reactor at NCSU still takes up an entire building.
Apples and oranges. You might as well be comparing a jet engine to your car engine, they have completely different requirements and applications.
nuclear power is cheap because it generates a ****ton of energy 24/7 for a year and a half. scaling that down to a truck throws that out the window. even on ships the advantage dwindles.
Firstly, it would go a lot longer than that between fueling cycles. Navy ships can go a decade or so, and it is not unreasonable to assume a civilian version could do the same. Secondly, in the coming decades fossil fuel prices will skyrocket. The advantage will become even more appearent than it already is.
and there is also the HUGE problem of shielding. probably the biggest problem with nuclear powered vehicles. if you don't want to kill the driver, you need a LOT of it. and it's heavy. trains wouldn't be that much of a problem by having the reactor car shielded and unmanned, but the only other land vehicle you're going to get is a slow-moving, long-range mobile bunker.
That earthmover I linked to earlier is the size of your average suburban house, and the excavators are often as big or bigger, and the quantities of fuel they use is huge (except the Bagger which is electric, but still uses a lot). That's the scale I'm talking about, not a little compact sedan.
i'm with you on this. not an obstacle. i'm all for arming the crews, nuclear boat or not. that and there's really not a lot a pirate could do with it even if they got it. make some idle threats is really all i can think of. besides, i'm pretty sure there already ARE nuclear-powered supertankers. if not now, there at least were before. i've seen a model of one someplace.
There was exactly one freighter that was nuclear powered, but it didnt work out because it was a traditional cargo vessel and back then container vessels were taking over the market. Also oil prices 50 years ago, when it was in service, were far less expensive than today.
