You can imagine it can't you

Imagine Mazdas drawing board of putting it in the car too..

surely they'd only need to look at a production NSU to see how to do it?

Mobile nuclear power station

you can't just leave us with that one picture.

Too right! Come on...More information.

Ok, ok

There is an awful lot on that site that would fit in this thread.

In the Soviet Union problems are studied regarding the use of small-size nuclear power plants for remote regions—regions located far from the power supply systems. Some examples are the areas of the Far North, dense forest corners of Siberia and the Far East. In these places, Diesel-type or thermal power plants are usually erected which are fired by transported liquid or solid fuel.

There are great difficulties connected with delivery of fuel to these regions. Therefore, for these regions small nuclear power plants could be expedient even today.

In the years 1961 through 1963 two small-size nuclear power plants were constructed: the TEhS-3, with a water-cooled and water-moderated reactor, and the ARBUS nuclear power unit, with an organic-cooled and organic-moderated reactor.

TEhS-3 transportable nuclear power plant

The TEhS-3 nuclear power plant, assembled with a large unit and with a water-cooled and water-moderated reactor of 1,500-kw capacity, was put into operation in 1961 in Obninsk.

It is very important that the construction and mounting operations for the nuclear power plants intended for use in remote areas be minimum at the place of operation. In this respect the TEhS-3 plant serves as an example: it was supplied from the manufacturing plant in a state ready for operation.

Practically all the equipment of the TEhS-3 plant is completed in four large units and positioned on four self-driven caterpillar platforms with heated car-type bodies. This makes it possible to operate the TEhS-3 plant without constructing special buildings, and preparation of the construction site is reduced mainly to the arrangement of the biological shielding. The total weight of the TEhS-3 plant equipment is 210 t (Table 5-1).

The weight and dimensions of the self-driven power units faciliates transportation by rail. The operation of the TEhS-3 plant since 1961 has confirmed its reliability, good controlability and easy servicing.

At present the transportable nuclear power plant is used as a research base for creating plants of a similar type.

What do you want to know? A normal Diff, or the various kinds of limited slip diffs.

does a ltd slip diff make both driving wheels spin at the same time or is that just a normal diff?????

[Muze ST]

I knows its not aginast the thread titles buts this is a great idea and works great just its always has a problem every day.

[Invisible man]

paint tin filling station?

[Muze ST]

no the verison i work will fill 1L 5L 10L bottles with a farming chemical.

When did we decide that all the cylinders had to be encased in one big lump of metal? Early car engines had separate cylinders like the photo.

And starting with single castings for the block and heads.

[Yoshiwaan]

What would that engine go into? As in what particular ship(s)?

Mr wankel - internal combustion engines...
Mate in pub - yeah
Mr wankel - not that great are they?
Mate in Pub - what do you mean? They are the best thing since sliced bread!!
Mr wankel - (sips pint) reckon I could do better...

Glad he's not my mate. Boring fker.

Unfortunately I am that man. Except without being a genius.

A "normal" (open) differential will send the power to whatever wheel demands it. More goes to the wheel with the least resistance. This is fine in 99% of normal driving conditions.
In some conditions, either in snowy/icy conditions or when you're racing and one wheel has almost completely broken traction, it's not what you want. Do a "limited slip" differential will only send a certain percentage of the torque to any one wheel.

The best way to imagine it is you're parked on a muddy verge. One wheel is on the tarmac.
With an open differential, it's possible to send ALL the torque to one wheel, leaving you sat stationary with one wheel spinning happily away in the mud.
With an LSD, that one wheel can only recieve *plucks number out of air* 70% of the available torque, leaving 30% to the wheel on the tarmac to pull you along.

I saw a documentary on Discovery recently ('Mighty Ships' I think) and the 14 cylinder version was developed to go into the "Emma Mærsk" which is the largest ship ever built that is currently in use. She can carry something like 15,000 containers!

Apologies that this a link and not a picture, but it really is (imo) worth watching... i was blown away by this piece of engineering... especially the bit on ice... scary!!!

OMG that actually made me feel quite scared, surely that cant be for real?

Me too. Imagine that wandering up to you on the battlefield.
