To all those that say no to consumerist frivolity and yes to beauty, utility, humility, and craftsmanship. We welcome all who see through the lies of the corporate disposable plastic racer agenda and choose to just ride on fine steel velocipedes

Over two years ago, Tesla open-sourced all its patents for electric vehicles – a surprising announcement in our IP-centric business climate. CEO Elon Musk explained the move as being in line with Tesla’s mission to accelerate the advent of sustainable transport:

“If we’re all in a ship together and the ship has some holes in it, and we’re sort of bailing water out of it, and we have a great design for a bucket, then even if we’re bailing out way better than everyone else, we should probably still share the bucket design.”

We might get access to yet another bucket design thanks to Proterra, a leading manufacturer of all-electric buses. The bus maker announced today that it will be opening its proprietary “on-route fast-charging technology” on a royalty-free basis.

I'm not sure how many buildings were knocked down but there are a bunch you can clearly see where they got cut off at the end to make room for the Central Artery.

then slowly sort out the rate of decent as I just want to fly strait and level for a while to pick up speed and gather my surroundings
next check speed and altitude set throttle to high check flap position and nose up the aircraft a little to for a slow climb
try and get on the radio to another aircraft or air traffic control just to find out where tf I am if the nav system is too cryptic

Any believers in Hyperloop here? Didn’t see a thread about it.
Musk is finally putting humans in the testing and doing 100mph tests.

I’d prefer rail over hyperloop in >90% of routes but I think this has potential for the inland West where distances between cities are long.

Btw if you think Hyperloop is completely stupid please elaborate why because I don’t know the technical specifics.

I went schizo on this post a little I’ll admit so what I’ll say is this- all of the standout cities in each state in the US that it would be fun to be able to hop between on trains are still like 6 hours away from each other on a 220 mph train. Just look on that map how far each one of the actually worth visiting cities are, they’re almost evenly spaced.

This guy is getting to the meat and potatoes of what's dumb about hyperloop.

Hype Loop is and always has been a solution in search of a problem. The USA doesn't need vacuum trains--it already has airport infrastructure. Hype Loop, much like most other Musk projects, has always been a scheme to milk subsidies. A way for the rich to get richer. Musk just shit it out as a dumb idea and then realized that Space X and Tesla were already making enough money and then gave up on it--leaving others to work with the scraps left behind.

Right now, Hype Loop is 100% just a ponzi scheme waiting for dumb government money, because that's the only way that this shit will ever make anyone any real amount of money. Hope to God Joe Biden people don't actually do.

As metal heats up, it expands; and likewise when it gets cold, it contracts. The weights you can see in the picture counter-balance this expansion and contraction, to keep the overhead cables in roughly the same place whatever the weather.

Dear /n/,
I bought my first bike after selling my old one five years ago. I don't remember how things were before, but on this bike the chain gets all black with chunks of the jockey wheels in less than 10km.
What does thit mean and how can it be fixed?

>I'm pretty sure the jockey wheels are getting worn.
well, are they?
take the chain off and scrape all the black gunk off the jockey wheels and check for wear. it should be obvious but I mean if your black stuff on your chain was pieces of the pulleys, you would find little plastic bits in the chain. the plastic doesn't liquefy, I promise you.
anyway, it's highly unlikely your pulleys are making whatever gunk is on the chain, but it's super easy to check if you want to be sure.

It's almost certainly just brake dust and air pollutants
but if it's jockey wheels then align your shit

>what's the draught like on these bad boys?
The St. Mary's River necessitates a summer draft of 27' but it varies with the age/design of the boats (and yes, they are technically "ships" but they have always been called "boats").
>do they sail the missippi and st lawrence? or just stay in the lakes
They're too big for the Mississippi, but they can sail the St. Lawrence provided they don't exceed the "Seawaymax" length of 740'. None of the Canadian boats exceed that length, since much of their business is along the Seaway, but the Americans have built some larger boats (the current "Queen of the Lakes" is pic related at 1014') which stay confined to the upper lakes.

For a little over a century, the majority of the lakers were based on the basic design of the SS R.J. Hackett from 1869. The Hackett was essentially a motorized barge, with the wheelhouse built forward for the sake of visibility, while the enginehouse was located at the stern end so as to keep the propeller shaft out of the cargo hold. This design lasted for so long in part because of tradition, and in part because it was popular with the crews themselves. Nevertheless, beginning with new Canadian boats in the early 1960s, a single, combined deckhouse at the stern end became standard as a cost-saving measure, and the final laker designed with the traditional configuration was launched in 1974.

has anybody else gone full /casual/ and loved it? it seems to me a lot of the anger Roadies have towards casual cycling is based on fear that once somebody tried it, they realize it's so much better, and they never want to do the roadie thing again. it's similar to racists fears about interracial dating. they want you to suffer with them rather than improve their cycling culture, so they try to scare you disparage casual riding on any way that they can. but the truth is really that once you go casual, you never go back.
and no, i don't mean unracer. unracer is like racing but for aesthetic points and requires some thinking and tinkering. I'm talking pure casual with poorly maintained bikes, zero thought, 30 tpi at 30 psi riding in a closed loop in a park. true casual
