This work has proven that it is in fact possible to go downwind, with the wind behind you, faster than the wind could push you alone. I personally can't quite understand how this is possible
It seems to be like you have this big propeller which is pushing the air backwards at 10 m/s. The wind pushes your vehicle forwards at 5 m/s but it also pushes the air from the propeller forwards at 5 m/s. Because this air is already being pushed back at 10 m/s the wind pushes it forwards at 15 m/s. In doing so it pushes the propeller and the car forwards at 15 m/s.
As other people have noted, this is a complete non-issue, sailors already do it, and there's no reason cars can't too.
"Land Yachts" are actually faster and more deadly than the version which travels on water because wheels have less rolling resistance (than moving through water) and they move across the wind with greater efficiency.
Same way an aircraft can move forward faster than it is descending while gliding. But I don't see how a sail boat can move faster than the wind when moving with the wind, unless you invoke storage.
There was this story about two birds which hung around an electricity substation. The male bird settled on one bus bar and the female on the opposite polarity bus bar. The male reached across to give the female bird a peck and....
The standard deviation in ability and price varies from place to place, in line with the amount and strength of regulation. There are very good private hospitals in Malaysia and they charge a lot of money, but less than you would pay elsewhere. There are also very cheap places which cut corners. They exist because they are not subject to the level of regulation you would see in some other countries.
I don't doubt your point about dentists in Egypt and I am not trying to rubbish medical care in the third world generally. My point is that some people will argue the prices down on things to a ridiculous degree and when that happens the supplier will be there to fill the market.
Ah well I am an Australian and my wife is Malaysian. Most of her customers are asian and believe in always getting the Best Deal (tm). My mother in law needed a tooth removed and would have paid 500 AUD for the job so she flew to Malaysia (which she was going to do anyway) and got it done for ten bucks (our money). She doesn't need all that modern sterilisation and anaesthetics. Those things were obviously invented to trick smart people like her out of their savings.
In Malaysia once I saw this nice watch in a street market. We drove the price down from 50RM to 10RM. Then the vendor took the case apart to install a battery. I realised later that he just put the 10RM movement in. We weren't really bargaining, just choosing.
I am sure the warning was in Engrish. The shipment should have been flagged in customs, but its not hard to get lucky there, especially if the paperwork from china looks okay.
"It happens every year around this season, they lose all balance and we find them fallen out of trees and the sky," she says. "Unless someone intervenes, they can't fly and will get picked up by predators."
Okay I get it. The problem is that people have been intervening so birds which should get killed by predators don't and the trait is passed on. Maybe we are breeding new species of animals which try to look cute so they will be picked up by animal hospitals and enrolled in breeding programs.
My wife works as an architect on small retail projects. One client of hers made a trip to China and bought a container load of material to fit out their project. So an electrician drills into a partition, hits asbestos and shuts the site down.
They lost a lot of money trying to save money on partitions. The funny thing is that the partition in question had stickers on it saying absolutely no asbestos. I guess there had to be a reason for that.
Yes in fact I can think of one individual I work with who buys his own work laptop so he can have the biggest one in the meeting room. I am sure there will be a small market for this device.
Slashdot Mirror
But directory will be exactly the same, just not in paper form.
But also some bombers don't know they are carrying a weapon. They may genuinely believe they are innocent.
I think your IP should be banned.
So....slashdot should have a police button?

The flight was only a little over 9min30sec
The flight went into orbit. Maybe the video went that long.
Its been slashdotted.
and nobody outside Australia knows about it, and we all think it is just some UFO flyover when they launch a rocket in to space.
Come on. Nobody here can keep a secret. Have you met an Australian outside AU who knows how to shut up?
Oz has every right to be worried when pieces of spacecraft come flying over them.
Eventually we will put all the pieces together and have our own space program.

The east coast of AU is at GMT+10 right now.
Did he forget that we're on DST right now? He should have looked up the EDT time, not EST.
We're not on Daylight Savings Time now.
They've been Loricuted.

Things should be blackened oot, eh?
Yes, just set the foreground and background to the same colour. These guys are amateurs.

Is McDonalds going to hire a hit man?
No, but the tipster wants to say employed. They no doubt have a family to feed.

The birds have caught Darwinism.

My guess is that the glasses and the tip come from the same source. Best for all of us if that person remains anonymous.
The glasses were made in China.

I don't see any Pierson's Puppeteers around. I think we should get out of here.
Don't worry, there's a Puppeteer right here beside me.
Though on the other hand, he readily admits that he is insane.
Happy 200th birthday.
