#203I love innovation and stuff. Radical ideas. But the aviation market is one of the most heavily regulated - bureaucracy beyond comprehension. Did you ever wonder why Piper or Cessna airplanes look EXACTLY what they did 50 years ago? And why the engines used in these planes (e.g., Lycoming) are referred to as “Lycosaurus”!? If you go for a sightseeing flight with a local aeroclub - you will find the pilot spending 30mi…
Aviation regulations are written in blood. They are the only reason you can step into an aircraft with a reasonable expectation of making it safely to your destination. Disasters are generally not caused by obvious large issues, but a multitude of smaller compounding, seemingly benign causes that could otherwise be easily dismissed. The massive body of regulation around aviation is a direct result of this. Each one i…
That regulations are motivated by avoiding deaths does not mean that they are effective at that, or even if they are effective that they are worth the costs. Regulations that specify specific safety equipment, rather than specifying target error rates or bonds/liability, are the worst because they get enacted and then stay on the books for decades unchanged.

This is just basic marketing. You sell to the guy who can buy. The Tesla company was started in 2003 to productionize the AC tzero. In 2005, the Roadster was conceived as the product it became and Tesla and Lotus tied up. The Secret Master Plan arrived in 2006. So yeah, that's just how it goes. Because there is an army of people who lament things targeted at rich people, but that army does not participate in progress…
That makes the current state of our humanity kind of sad, doesn’t it. It is also not true. There are numerous innovations targeted for the betterment of us all. The three-point seat-belt is a quick one that comes to mind. The field of medicine has tax funded research innovating at a remarkable frequency, where the target beneficiaries is all humans who need it. Expensive infrastructures like roads, train networks, el…
It's always been the case. We linked the world via trade in search of making a rich man's food taste better. I don't think it's sad. I think it's wonderful. The rich 'subsidize' progress for everyone.
All of the things you mention (except the 3-point seatbelt, perhaps) have a story just like this one with some guy saying things just like this guy and a veritable shower of lament with no effort behind it.

Private pilot here. Yes, aviation innovates slowly, but it's not nearly as bad as you make it sound. Cirrus aircraft have been a game changer, as has the Garmin G1000 avionics. I can fly just about any instrument approach entirely on autopilot. The only thing I have to touch is the throttle and the flaps. I get real-time traffic information via ADS-B, real-time weather via Nexrad. I do my flight planning in five minu…
Lots of innovation has happened in aircraft electronics. The powerplant? Not so much. Most light aircraft engine designs are four or more decades old, and the only ones cheap enough for a moderately-priced aircraft have carburetors. I don't think you can even buy a car these days with a carburetor, but with airplanes they're still standard, even though fuel injection makes a lot more sense in an airplane than in a car. You can get airplanes with fuel-injected engines, but a fuel-injected Lycoming IO-390 engine (like you'd find in a Cirrus) will cost about $27,000. Used. Just for the engine. You can get a decent car for $27,000, and it will absolutely have a fuel-injected engine. Likely a turbocharger as well. And the car's engine will produce a lot more horsepower.
Oh and you'll have to fuel the airplane with avgas which costs $5/gallon and contains lead, and you have to wonder WTF??
There's no technical reason aircraft engines cannot be turbocharged, fuel-injected, fueled with regular unleaded gas, and cheap. Aircraft engines should have followed the innovation advancements that have happened in car engines, but they haven't. This is probably because of regulation, monopoly power, liability, and a host of other reasons, but as an engineer I find the situation ridiculous.

I absolutely guarantee this will be anything but less expensive. You can get an R44 with better range and payload for a couple hundred thousand. This will be an electronic nightmare requiring extensive certification and maintenance efforts. Cessna can't even sell ridiculously old designs for reasonable prices due to certification overhead.
It might be less expensive due to the electrical powerplant. It will take a while before there is enough of a track record to know for sure. But, for example, electric cars are much lower maintenance than gas cars, as Tesloop as shown. https://cleantechnica.com/2017/09/05/10492-tesla-model-s-mai... https://www.tesloop.com/blog/2018/7/16/tesloops-tesla-model-...
Disregarding that they have a lot of free "Goodwill" replacements - their post-warranty maintenance costs are about $0.17/km - my ICE Ford is at $0.09/km over the past seven years post-warranty. (And I think I've included more items in my spreadsheet, since I've got the cost of things like windshield wipers and fob batteries, which they omit.)
edit: I thought looking at entire lifespan of the Tesla might be unfair since that includes a much longer period when it's significantly higher mileage than my car, but taking only an equivalent post-warranty period is even worse, it's about $0.24/km in maintenance over that time frame.

>let us not compare a 50k used Cessna to a 500k Cirrus? why not? the original post was that innovation can't happen in aviation because of regulation. if we're shifting the argument to innovation doesn't happen because it's expensive, that's a much more solveable problem.
Let me rephrase: The innovation you describe (which is cool and needs certification) bumped the price for a new airplane from about 50k in the 70s (I guess we may be talking 200k in today’s money) to close to 1MM USD. And that innovation is “just” glass cockpit, and some more advanced avionics. Not changing the principles - you fly a bit faster, a bit safer but still need a license and do all the preparation and chec…
There's a lot of innovation now happening in the experimental/amateur-built category. Super-capable avionics, GPS everywhere, electronic ignitions and advanced engine intelligence/management. And for reasonable cost (relative to a new Cirrus and even a new Cessna). If you're willing to do the building yourself or trust another builder, you can get a very capable, modern airplane for under $100K that puts the certificated 1970s Cessna to shame in every measurable dimension.

#208This to me is a true moonshot and venture-worthy idea. Some of these concepts may be technically or economically infeasible—it's a major risk—but the pay-off for human wellbeing is phenomenal. I wish we celebrated more companies like these, but it seems like most of them are met with (well-earned) skepticism rather than genuine curiosity. The world of atoms is harder than software, but it's awaiting disruptions like…
I dunno man, im getting kind of jaded as I get older. "True moonshot" to me seems more like cheap clean water for everyone, or a real way to sequester carbon, not a way for rich folks to get to their country cottages faster.
I feel like I’ve heard so many ‘cheap clean water’ ideas over time that I’m sure it already exists.
The problem is probably nobody wants to pay for that.

Not saying that all aviation regulations are bad, but the fact that carburetors are still used in general aviation is pretty damning.

That's the autotrain. Carries passengers AND the car. T https://en.wikipedia.org/wiki/Auto_Train
Is it on a ferry or is the map just not accurate there? I don't see it on the list. https://en.wikipedia.org/wiki/Train_ferry
No, it travels on the main East Coast line that runs from Miami up to DC. What it doesn't do is STOP at any of the intermediate stations. It leaves the DC suburbs in late afternoon, and drops off just outside Orlando, Florida in the early morning of the next day.
