Study finds health risks in switching ships from diesel to ammonia fuel
Study finds health risks in switching ships from diesel to ammonia fuel
Without additional regulation, burning ammonia in ship engines could cause serious impacts on air quality that could result in more than 600,000 additional premature deaths per year, according to new MIT research.
Technically not green, but I thought you guys would be interested
I've been interested in green technology for decades, but it's always important to make sure we're not just replacing one pollutant for another, and that new technologies are actually practical.
If there were really simple solutions, we'd be using them already much in the same way we moved from HCFCs to HFCs for air conditioning and the way we moved from leaded to unleaded gasoline.

Nothing is. An example, the UK cut all its big trees down to build sailing ships back in the 1800s for example and then went overseas to exploit forestry there. A good read on that is The Golden Spruce

Physicist Tom Murphy is doing an excellent 18 part critique on that now, he's up to part 10 which is excellent.
The funny thing about air conditioning fluids, is that we are actually moving from HFC to propane and ammonia, due their green house effect.
Aka the thing that CFC were supposed to replace because they were safer.
It is a circle.
I thought they were talking about electric ocean liners?
Not in this article, in general.
Batteries don't lend themselves to boats unless they have generators.
Maybe hybrid ships recharging their batteries works but I doubt it.
Electric ships have to have generation somewhere. You'd have to do a lot of work to ruggedize solar panels to handle the travails of the sea. Wind power might help some.
Nuclear power works for US aircraft carriers but it's expensive as hell compared to Bunker fuel and a big ole engine
