Greetings from the Republic of Danmarc.

We are expanding our Naval capacity, and would like to do so with the purchase of 8 of your heavy destroyers.. Payment will be made upon confirmation of the order. Thank you

Question (i'm new to railgun tech)

What's the range on those railguns, and how many shots can each one of them put out per minute?

Confirmed and let me edit that in as well as some more information.

[OOC: If you're claiming that a hull of this size is made of nanotubes then set a more realistic price like $100bn.]

ooc: Do you think the entire thing is made from nanotubing? I'm only utilizing about 1,000 tons of nanotubing, which at $1 per gram should cost about $1 billion, I'll raise the price to $5 billion to make you happy.

[OOC: Currently nano-tubes cost $500 per gramme. And that's just the structure.]

That was back in 2001.

Single-walled Carbon Nanotubes can also be done for less than $1 a gram with a high pressure carbon monoxide process. And no, they're not $500 a pound, I checked the prices.

Another way for cheap mass production of carbon nanotubing is electrical arc dissolution of carbon in a helium atmosphere, followed by purification in hydrochloric acid, which is a relatively cheap process given the components involved.

[OOC: According to everything I've ever seen and been told, they cost $200 - $500 per gramme unprocessed and of a decent legnth. I've never seen that before, and as it seems to contradict everything else I've seen, I imagine that they either under estimated the price or are producing only small and relatively impure nanotube strands and nothing anywhere near good enough to make into armour.]

ooc: Most of the articles are from around 2001. Current prices for SWNT are definitely lower than what you stated, and a Norwegian company can currently produce several kilograms per day per generator with a rather inefficient liquid process.

I use a more effecient electrical process with a fairly simple refining process using HCl.

All you need to add is carbon and electricity.
