Hawaii Seaglider Initiative Launch

newtboy says...

It’s a ground effect hydrofoil sea plane inter island electric ferry concept, so it’s near its limit in the video.
Ground effect refers to a flight characteristic noticed at low altitudes where the air below the wing compresses between the wing and ground, creating enormous lift with smaller wings or winglets. This makes them much more efficient, especially at lower speeds or with heavy loads.
The largest I know of is the Ecronoplan- https://en.wikipedia.org/wiki/Lun-class_ekranoplan)

Here’s a bit more info
https://www.hawaiiseaglider.org/

Many “birds” make use of this flight characteristic to save battery power during long term surveillance flights, especially just offshore.

Pretty cool! Is there a limit to how high it can climb? I like the wings. Kinda reminds me of the unreal "birds".

EMTs charged with murder

newtboy says...

I think it’s not uncalled for to throw in hate crime enhancements and go for the death penalty. Let them prove their murderous callous behavior wasn’t racially driven.

Their training means they absolutely knew what they did would kill someone in his condition. No question. This wasn’t even depraved indifference, it was pure premeditated callous torturous murder. My absolute worst nightmare death.

The only truly just reward is to slowly suffocate them by compression…compassionately offering them a light sedative to speed things up slightly. A lot of tragic things happen in life, and I think they need a little tragedy in theirs.

What they’re going to get won’t come close to justice.

Just disgusting.

D-Cycle Piston by YAN ENGINES

TheFreak says...

I see 3 times as much rotating mass. Plus the exhaust lifter has to be under spring tension and lifting that every compression and exhaust cycle is going to add more losses.

Also..."your exhaust lifter bearings are shot. You're going to need a full bottom end rebuild." :-(

I don't know if you were being a smartass or just didn't know, either way, football means both american football and soccer.

Texans Have The Biggest Haboobs

AeroMechanical says...

The motion where the sand meets the ground doesn't look right. Doesn't seem like the sort of thing someone would intentionally fake, maybe it's just the video compression, but anyways, it doesn't look right.

Why Tesla is building city-sized batteries

newtboy says...

Nice to finally hear pumped hydro mentioned when discussing energy storage.
Sure, it takes space, but it's non toxic, proven, doesn't bleed off like compressed air, and doesn't wear out every 10 years. Chemical batteries should be just for quick load shifts with hydro used for the majority of energy storage, imo.

CeramicSpeed 99% Efficient Drive Shaft // Chain Free Bike

newtboy says...

I thought this lends itself to a spring loaded spiral shaft automatic transmission, where the more torque applied, the more it compresses the spring towards the front crank, lowering the gear you're in. This could be adjustable, allowing a rider to select how hard they want to pedal and automatically adjusting the gears to keep that force stable at any speed.
A second gear in the rear, rotating in the opposite direction and sandwiching the drive gear, would go a long way towards stopping slippage and gear wear. They certainly need to ditch the aluminum gears, though.
Just what sprang to mind when I saw it.

I'm curious to see what mechanism they use to change gears.

Not sure if the dog has enough weight to make good enough compressions. But can't blame him for trying. And then to listen for breathing?

New Rule: Trump Is Above the Law

RFlagg says...

It clearly says "He could appear" as in he hasn't said it, but could say it. It is following his own example of how he said he could shoot somebody. I know reading compression isn't his strong point, hell, we all know he can only read comfortably about a 4th grade level (though I have no doubt he could read at the typical 9th grade level with a bit more effort on his part), but I'd expect more from some others...

Trump won because Christians hate Democrats, despite the fact the Democratic party is closer to Christ's teachings than the Republicans are. Hell, we almost got a child molester as a Senator because the Christians didn't care if he was a child molester being true, they'd vote for him over the Democrat, who is also notably a Christian man... just doesn't act inappropriately around little girls. The only reason Roy More lost in the end, was because he went the extra mile to say America was last great when we had slaves, and we should get rid of all the amendments but the first 10, like the ones that allowed women and blacks to vote. Now they'll soon have the ability to persecute others for sinning differently than they do, which is modern Christian's goals. "How dare that person be gay, my sin is nothing, their sin is gross, and I don't give a fuck what Jesus said about loving one another, or not tossing stones, or treating others the way I'd want to be treated, I'll treat them with bigotry and hatred, but I'll tell them I love them, I just hate everything about them, because I'm Christian after all, love the sinner, hate the sin." Again, not a direct quote, just what one has to be thinking when they say they don't want equal rights under the law for LGBTQIA+ people, and won't bake them a cake for a wedding, because there can be no other thought process to ignore the golden rule and everything else Jesus taught. Recall, I used to be a hardline Fox news, GOP voting fool, but couldn't reconcile the teachings of Jesus with the GOP... and eventually, because only I seemed to have had that revelation, lost faith in the ass, and even if he is real, I'd still rather burn in hell than be around my family and the rest of the far right for all eternity.

It also has to do with a severe lack of education. 40 some percent of American's believe the universe is 6,000-10,000 years old because their Bible says so. A large number doesn't accept the science of climate change... too many idiots believe Fox news is honest and truthful, because they don't care to learn how to properly vet news and information.

Also has to do with greed. Pure unadulterated greed. People caring more for their pocket books, their job situation, than what will do the most good for the most number of people.
