Matthew L. Wald at The EcoModernist:
A container ship looks like a perfect place for a nuclear reactor, from a technology standpoint. But a lawyer might call it the worst. It’s a good example of the divergence between what the world needs, and what the world can get.
Here’s the engineer’s view:
A container ship has a steady energy demand of tens of megawatts, and consumes a lot of oil to cross the oceans. Many ships are “slow steaming,” cutting speed to reduce fuel burn, and a 10 percent reduction in speed cuts fuel consumption by 30 percent.
If the energy were cheap, ships could be designed to travel at 35 knots instead of the 16 to 25 knots that is now standard. That could make one cargo ship do the work that now requires two. In addition, each ship would have more space for cargo. Container ships today have big tanks for millions of gallons of fuel oil, and the engines can be more than 40 feet high and nearly 90 feet long.
And technological progress makes the idea of powering ships with nuclear energy even more attractive.
