Wouldn't any heat energy gains be negated by the energy needed to ship the heavy iron from the Sahara to the Netherlands?

- fpoling 6y agoThe energy cost of sea transport is like 50 less per distance traveled than on land and it has being like that for the last 3000 years. So the cost of shipment to Netherlands is just a cost of transporting to the nearest sea port from Sahara.
- ohyes 6y agoyou need to run your ship on iron fuel as well. I guess that is the test though, can it ship itself?
- Ichthypresbyter 6y agoI think an iron-powered ship would have to be a steamship. There are still a small number of steam-turbine-powered merchant ships being built- specifically LNG carriers, where gas that boils off from the cargo can be used as fuel.
- benibela 6y agoIn Lensmen, they build iron-powered spaceships They are far more powerful than other kinds of spaceships

- joe_the_user 6y agoIron is heavy, dense as a material, but the cost-efficient of moving it around as an energy store depends on it's energy density (and it's initial cost), not it's basic density as a material.
