Why not an RC Zeppelin with nuclear RTG powered fans, that also uses excess power to generate replacement hydrogen from ambient moisture.
Now THAT sucker would be up there forever. I'd live in one if I could.
The website you get following the "hydrocopter" link in the article states pretty clearly:
HYCOPTER is being readied for a record flight endurance of 4 hours, or 8 to 10 times the average flight duration of equivalent systems today.
Which is about right based on even high-end drones consumers use today.
The article has a picture of the CURRENTLY WORKING drone. It doesn't have large tanks of anything, it has two small tubes of hydrogen.
I think you have greatly miscalculated the pressures needed by this system. It's not storing pounds of the stuff, just 4oz or so across two fairly large tubes...
anywhere north of the south pole such that, after walking south one mile, the "circumference" of that latitude is one mile, or some integer fraction (e.g., 1 mile west results in 4 "laps"), then one mile "north" will return to same starting point.
I did - the facts are that the Clinton foundation claims to be a charity, but uses almost none of the money collected for charity. The facts are that the foundation gained a huge boost in donations from people while Clinton was in the state department, from people/governments who had matters being decided by the state department...
If you want to ignore the facts, fine. Just don't claim to be for them at the same time.
Sure, if by "never contacted" you mean "given lots of money, along with other people on the panel, to vote a specific way".
Are you really so naive? You don't even have to dislike the clintons to understand the fundamental flow of money involved here and just how easy it is for that to have an effect on the results.
It's also stupid on the face of things to claim Clinton had no influence when donations to her charity fell drastically after she left the state dept... You don't need a tinfoil hat to pick up the subtle single there.
Rich people are richer because they, overwhelmingly, inherited capital from their parents.
It was tried for a while, the 0 dollar wage. It was called slavery, and it DID work. The plantation owners were the wealthiest humans to ever walk the planet. Still might have been, adjusted for inflation. A great success. Those owners would have bought the world up with their wealth, bit by bit, had slavery not been sort-of stopped. Of course, normal non-slave humans were competing against free labor, and so barely got by, with lousy schools and dirt roads and abysmal ignorance that lasts to this day. We paid a lot for that free labor, didn't we? A truly "free" market - once side got their goods for free.
And that is only if they weren't forced to take it out of the their net profits, instead of the customers' pockets. They've made a KILLING in profits.
People were paid 18/hour in 1966 to work like a dog at McDonald's (you've never worked a restaurant chain job, I see). And the corporation grew into fantastically profitable giant. Seemed to work.
And people who get paid minimum wage don't get forty hour work weeks. They usually are capped at 18-29 hours, to avoid full-time employee status. And the work hours are jangled weekly so they can't get second jobs. Fun!
You're not everyone. And you've no imagination when it comes to life's little snafus. I take it life has treated you well. You've never really been too ill, or blacklisted, or locked into a bad situation because of family issues, or been unable to find employment because of past accusations or convictions, or had a nervous breakdown, or been hit by a car and been unable to function, or been employed in an industry that was gutted for profits.
And no, you've not seen the minimum wage jacked over the years. It was down to 40% of its original value even after all the "jacks", until finally someone performed arithmetic and found it started life at $18 an hour.
Worth, to whom? People who work 7 buck an hour burn a hell more calories than you do, probably. Your version of their worth has a lot with your perception of yourself. Who gets what is a rigged game.
