Welcome to /c/tumblr, a place for all your tumblr screenshots and news.

Our Rules:

  1. Keep it civil. We're all people here. Be respectful to one another.

  2. No sexism, racism, homophobia, transphobia or any other flavor of bigotry. I should not need to explain this one.

  3. Must be tumblr related. This one is kind of a given.

  4. Try not to repost anything posted within the past month. Beyond that, go for it. Not everyone is on every site all the time.

  5. No unnecessary negativity. Just because you don't like a thing doesn't mean that you need to spend the entire comment section complaining about said thing. Just downvote and move on.

I know it's just me, but everytime I hear the expression 'What a time to be alive!', I think of the voice of the host of the Two Minute Papers YouTube channel.

Edit: I thought it was just me, but it wasn't just me

A fellow paper enjoyer!

btw cargo ships are already incredibly efficient tho.
even if they produce a ton of co2, when divided by actual amount of goods delivered, they are hundreds of times more efficient than trucks

[–] Stamets@startrek.website 4 points 11 months ago

Oh absolutely. But why not make them even more efficient?

[–] optissima@possumpat.io -1 points 11 months ago (1 children)

Okay but can we compare them with trains first.

[–] WldFyre@lemm.ee 3 points 11 months ago

Sure! What trains deliver goods across oceans? Or between distant continents?

From the Wikipedia article linked below:

A rotor ship is a type of ship designed to use the Magnus effect for propulsion. The ship is propelled, at least in part, by large powered vertical rotors, sometimes known as rotor sails. German engineer Anton Flettner was the first to build a ship that attempted to tap this force for propulsion, and ships using his type of rotor are sometimes known as Flettner ships.

See also the Magnus effect.

I was ready to mock this, but the more I look into it the more sense it makes.

[–] Stamets@startrek.website 3 points 11 months ago

Honestly I had the same thought process

If you want Atlantic trips to take months it sure does make a lot of sense

[–] atocci@kbin.social 7 points 11 months ago (1 children)

From the article:

Estimated average speed of the Oceanbird is 10 knots. A transatlantic crossing with 7,000 cars onboard will take around 12 days (today’s crossings takes about 8 days).

[–] Obi@sopuli.xyz 3 points 11 months ago

Sounds utterly acceptable.

Let's be real, we all love movies with wind powered fantasy-esque ships or conventional public transport. Sailing is just so cool and trains and trolleys are convenient or in my mind even whimsical. Why shouldn't we take modern approaches to sustainable and minimally polluting technologies?

I took a road trip halfway across America and I have to say, having a ticket for a sleeper car would have been cheaper, faster, and convenient. Why can't we have that option?

Isn't it like 20% fuel reduction only? Not insignificant
