Diamond Block?

[HampusA]

Well this whole thing fails because you would have to find a diamond as big as an engine block.

Otherwise you´d have to glue the parts together and well that takes away the goal of the diamond block.

HYPOTHETICALLY, as in if diamonds were cheap and easily machined, wouldn't diamond be good for an engine block? or at least a coating for the cylinders?

We all know it can't actually work we just wondered about the idea. I detect no 'fail' here.

Nonsense, artificial diamonds can me made up to one cubic meter nowadays.

O wow really! I didn't know about that, got any pics?

I mean diamond has a low coefficient of friction and a high thermal conductivity, its also pretty strong. How heavy is diamond anyway? What about alternatives?

Tear my theory apart please, I always think of stuff like this and theres always a hole in it somewhere, I just want to know where so I can casually move on to the next half baked idea.

Diamond's strength can't realisitaclly be used. It's low toughness and cleave planes on it's structural lattice means it's not a good structural material.

You mean it shatters easily i assume? If so, we been there.
