Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.
As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades:
How much each change to the atmosphere has warmed the world:
Recommended actions to cut greenhouse gas emissions in the near future:
Anti-science, inactivism, and unsupported conspiracy theories are not ok here.
Didn't expect us to see a fully electric ship any time soon tbh, but we certainly need more hybrid ones to reduce air pollution around ports.
At full power it has about 10 hours of charge based on the numbers they provided. I know ships don't necessarily run at full power all the time, but what kind of power usage is used while cruising? Is this only going to do short trips or does it use like a tenth of that power most of the time.
I work in the industry. as I see it this will be used along the major harbours along Chinese coast. if we see them elsewhere it could be along the east/west coast of the US or Mediterranean in Europe. but it is limited. and not global trade. more like regional distribution. also as a Dane. we have two electrical ferries connecting to other countries. this is super interesting as they are running often small routes and thereby reduces local air pollution a bit similar.
That does make more sense. I know we have a hybrid ferry in Portsmouth but I think it is more designed to reduce emissions right next to the city and then charge up on the main engines while crossing. Not that it ever gets more than a few miles from land but I suppose its slightly better.
well you made the 10 hour claim calculation :) 10 hours ain’t long. it takes about 3 weeks from Asia to Europe shortest route. 24/7. so a 10 hour journey limits that usage ;) I seem to remember from Bremer Hafen to Hamburg it easily can take 6-10 hours. due to waiting and traffic. so it will be short harbor routes for sure ;)
10h is based on the article for the energy stored and the energy used by the motors. But it would be if the motors are running at 100%
I'd love for everyone to go full electric. The US is literally doing the opposite though, so I wouldn't expect to see these in American waters for a long time.
boy I really can't wait for the environmental disaster that it will make when it sinks.
oil spill, battery fire that can't be put out,.... probably rape some fish while it's going down IDK I'm not a shipwreck expert
The battery compartments are built to be removable by the sound of the article, most ships don't sink unexpectedly. I am kinda curious what the environmental impact would be of an electric boat sinking, we sunk a shitload of them intentionally in the past...
Given that the conventional ship it replaces might carry a couple of thousand tons of fuel, that's still a net win.
What chemistry batteries does it use?
