Loved this doc. Loved sharing it with my engineer/artist/military pilot brother.

1. Never trust anyone who says "basically" too much about things that aren't basic at all.

2. I don't see Taco Bells, Walmarts, and other terrible elements of suburban life. I don't know how that'll float (ho ho!) in South Korea, but it'd never hold water (ho ho!) in the US.

3. I agree with newtboy. I'd like to know what sort of people are on their payroll or board of directors. Do they have all the sorts of scientists ad engineers you'd want for a project like this or just a handful of pie-in-the-sky Silicon Valley-ish types?

What I wonder though is how much medical equipment can be carried and if someone is in dire need of medical attention at a hospital, won't they still have to wait for the helicopter anyhow? I guess if the medic can get there quickly to stabilize the person...

Anyhow, not saying this doesn't have valid use cases but I see this having more military or industrial/engineering applications.

Effective January 1, 1996, leaded gasoline was banned by the Clean Air Act for use in new vehicles other than aircraft, racing cars, farm equipment, and marine engines.

Why not altogether? Who fuckin knows- prolly lead brained idiots think it's better for their farm equipment. They spew exhaust into the chief export of Indiana: Corn. You know, the syrup they put into basically every food you eat.


Fun Fact: "Lead does not biodegrade, or disappear over time, but remains in soils for thousands of years."

But hey, you can save a few pennies if you poison the entire planet for the next few thousand years now... so... VOTE REPUBLICAN

If the viper had a mid-engine and traction control it wouldn't have been close, but that thing is legendary for being very challenging to drive well. Very stupid to try that with a viper on public roads without knowing what it will do!

Mr engineer, when there are two parties, sentence structure demands you use plurals….both sides have THEIR share of undesirables. An engineer should see grammar as a clearly defined structure that follows simple rules and just get it. Spelling is different, but grammar should be a no brainer….why is it so hard for you? Have you never seen it that way, or was engineering incredibly difficult for you too?

The difference being one side is all undesirables, and the level of undesirability. One side openly calls for an end to American democracy, death for their political rivals, death for anyone who disagrees with today’s talking point. One side has no party platform, no stated goals, and exists solely to stop any legislation the other side puts forth, even when it was something they want or that would benefit them. They are the same side.

We found another point of agreement.

Term limits are a must, and will never happen because our system does put the regulatory onus on those who need regulating….absolute insanity. It also lets them set their own salaries, ethics, and benefits.

Divestment is another must. Perhaps a bigger must. Total divestment across the board. Not just blind trusts that aren’t really blind, and absolutely not what we have now…the “honor” system run by the honorless. Allowing legislatures to write horrific laws because they can personally financially benefit is a recipe for disaster. That should (but never will) change.

Campaign finance is a third must. Corporations should have the same donation limits individuals have, which should be more like $100 each so every person can afford to have a voice, and we should return to an equal time on broadcast tv for free situation and deny the media as a political platform to give candidates a boost….no more Fox News interviews indistinguishable from campaign commercials, no more media smear campaigns, with severe penalties for violations, like $10 mil the first time, $25 mil the second, loss of fcc license the third. Another non starter….but needed badly.

PACs should be outlawed, or regulated into obscurity.

Some reasons often brought up in opposition to term limits can be traced back to Maddison who wrote "[A] few of the members of Congress will possess superior talents; will by frequent re-elections, become members of long standing; will be thoroughly masters of the public business, and perhaps not unwilling to avail themselves of those advantages. The greater the proportion of new members of Congress, and the less the information of the bulk of the members, the more apt they be to fall into the snares that may be laid before them,"

I think we have proven at this point the cons of self serving representatives legislating for personal gains outweigh the benefits of professional legislators, especially seeing as we have the internet and huge staffs to ostensibly level the playing field of knowledge.

One fix would be the creation of an ethics branch, completely non partisan, not self regulatory, with rules against former candidates (winners and losers) and lobbyists too from serving and strict rules about how they operate, and bans from running for office or being a lobbyist afterwards so it doesn’t become a campaign platform or tool for industry. Maybe even ban close family members from the same. Won’t happen, only the best people intentionally limit their powers, and they are few and far between in Congress….all but absent on your side.

SpaceX launched its Falcon 9 with 48 Starlink satellites aboard to low Earth orbit Wednesday. During the countdown, a SpaceX controller during a satellite launch said "Time to let the American broomstick fly and hear the sound of freedom," in a jab at Russia.

The comment was in reference to a recent statement by the head of Roscosmos, Dmitry Rogozin, who claimed that a ban on Russian exports of rocket engines would force the U.S. to rely on "brooms" to get to space.

Starlink is a space-based system that SpaceX has been building for years to bring internet access to underserved areas of the world.

I thought by comparing itself to existing technologies, it was being up front that it’s just moving from purely theoretical to prototype. Maybe that’s not as clear to others?

I’m fairly certain every single point there was made about the Wankel when it was prototyped…look at it now! Edit: in fact, wankel side seals are the likely solution…it has the same rotary “side bleed” issue and they do ok.
Same for reciprocating piston engines and more.

Sure, it’s not ready for prime time, and no, it is no where near it’s theoretical potentials. What engine has been at this point? They got it to run, I’m pretty impressed with that as it’s much farther than most theoretical motor designs ever get.

No.

What kind of tolerances do you need to seal the chambers created by those rotors and then what happens to those tolerances from thermal expansion when the engine heats up?

Now ask yourself how you lubricate all of that and then notice the oil literally pouring out of the front seals of that engine.

All of those numbers are made up. Maybe someone did some creative theoretical napkin calculations but those numbers aren't based on anything that engine is doing.
