Read on - what they were really afraid of was the dirty/smelly poors coming onto their precious island. You see the same BS with bike paths through residential neighborhoods. Despite studies showing that bike paths increase property values, residents bitch and moan about safety/crime. They basically figure that poor/non-white people will bike into their neighborhood and rape/pillage/burn everything. So you get a bunc…

Heh, I was just trying to picture Some Puerto Rican Guy on a bike, cycling into rich white neighbourhoods.

The only criminals on a bike that I'm aware of are bicycle thieves.

I'm not saying _anything_ about crime. I'm disputing the assertion that bike lanes inevitably increase property value.

One case where they don't would be commercial roads with small shops that rely on street parking. But the comment you're responding to was talking about residential, and I haven't seen enough dispositive data on that one way or another. Like anything, it's probably a mixed bag.

Nope. There too. It turns out that foot traffic and bike traffic do a lot more for small shops than cars do (because drivers go fast enough that they don't pay attention to 90% of the small shops).

Nobody wants to talk about the real solutions that are boring apparently

Is it a real solution when for some strange reason it's impossible to build them? Also I love trains. I moved back to Miami and there is a train called Brightline that goes from Miami to Orlando. It's extremely nice and my preferred mode of travel. Imagine if we had a bullet train that just spanned the entire east coast...

It took 22 years and almost $7B to build 22 miles of MRT (not high-speed rail) just outside of the DC beltway, and much of the route had an existing right-of-way. It's a populous area, but the DC to Boston route is quite heavily developed.

Acela tried... $150B pricetag :( https://www.railway-technology.com/features/featuregrand-pla...

That $150B estimate seems wildly optimistic to me as well.

We've sold over 467 seagliders with a $7.9B order backlog spanning global aviation and ferry customers. I would think this is pre-launch sales. It's probably hedged with "subject to certification" risk, but it's still pretty solid, and if it came with sufficient deposit fundings to bootstrap the assembly line, all to the good. But, my understanding is that both boats and aircraft (and this is a join over the two) inc…

Seaglider entry to service is slated for mid-decade so you're spot on, all these are pre-launch sales. We're one of the few companies in the space with firm, nonrefundable deposits and contractually obligated pre-delivery payments (that scale with milestones as you mentioned) on the full first year of these orders. We take off at the periphery of harbors and fly over the open water in-between. Seagliders have 5ft wav…

It seems intuitively like there would be potential for inland use along navigable waterways as well as coastal use-

I'm reminded of the Boeing 314 "Clipper" flying boat, https://en.wikipedia.org/wiki/Boeing_314_Clipper Apparently it did have range enough for, say, between LA and SF, non-stop.

One famous specimen flew SF to NY, but the long-way around[1] (and obviously not non-stop)

There are rules of the road for seafaring which apply even to these types of craft. A sailboat usually wins over a powered craft.

so if a sailboat suddenly veers into the path of this thing, what is it going to do? Collide or ditch "GEVs may be unable to climb over or turn sharply enough to avoid collisions, while drastic, low-level maneuvers risk contact with solid or water hazards beneath. Aircraft can climb over most obstacles, but GEVs are more limited. "

It's nearly impossible to create a ground effect vehicle that can't fly out of ground effect for a limited time.

They need a significant amount of extra power to get out of the water in the first place, so there will always be more power available to climb out of ground effect.

The maximum altitude would be limited, you wouldn't be able to climb over a mountain, or over clouds. Depends on the exact specs, but should be more than enough to clear large ships, or at least get the altitude to make it safe to do a steep turn.

What's the legal authority permitting "seagliders" to carry passengers but escape aviation regulations? Or to use navigable waterways at high speed when other maritime users are severely restricted in speed? I doubt any historical exceptions would stand up to significant use. What's the real benefit? Actual ground effect is strong but very, very limited - to about the width of the wing. The (wallowing) demo flight is…

No loophole nor exceptions - we're following guidance from the International Maritime Organization on the maritime regulation of Type A WIGs ( https://wwwcdn.imo.org/localresources/en/OurWork/Safety/Docu... ), which have been upheld by flag states all around the world. The benefit of ground effects are: - 10-20% range extension (agreed, between 50% and 100% wingspan, which is where seagliders fly, the aerodynamic ben…

Doesn't the landing make a huge impact/force on the foils? I would think that they are designed to make the craft go up, thus more susceptible to it going down at higher speed?

> Seagliders have 5ft wave tolerance on takeoff and landing But do sea glider passengers have a 5ft wave tolerance? That sounds like a wild ride. But this is exciting... as someone who remembers taking the Hoverspeed SR.N4 from Dover to Calais, I know fast coastal transport innovation can be a game changer.

If you look at the distance between the hydrofoil and the hull midsection, it looks to be about 5ft or so. I would suspect that up to 5ft of wave has very little affect on the ride smoothness.
