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.

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?

That doesn't look practical at all. The point of cargo ships is to move containers, so they put them out in the open for rapid loading and unloading... Plus this "aerodynamic" design makes no sense. Most of the drag comes from what's under the water at low speeds and if it's a sailboat the wind will be behind them. At the scale of cargo ships some are 400m long, meaning these sails could be 200 m or more high... the small flexible blades on a wind turbine are 80 m at most.
