Where does the ocean's salinity come from?
An average male Blue Whale releases around 16 litres of semen in each ejaculation. There are a lot of Blue Whales in the ocean. You figure it out.
It's do do with the dissolved minerals that run-off from land and from the seabed. And it's not just salt - I keep a large marine system and there's untold number of trace elements that go into that.

And fish excrement. A LOT of fish excrement. I only have 30 fish, most are under an inch or so but a couple are about the size of my hand, and I'm taking out about a litre of fish-st every two days from the protein skimmer. It's a vile mix of digested seaweed, krill, and brine shrimp. It's great fertiliser though. But it stinks. Really stinks.

I don't know if tastes salty though.

I wish I hadn't read that.
Year/day error and 58m is <100m but otherwise good.
However you need to know the length of time it hangs around because you arbitrarily chose a day (well... a year) and compared to the volume of ocean water.
If 10k whales are wet dreaming daily since the Jurassic period and it's some magical everlasting jizz then that might be enough, no?

paperbag Ta for the error checking.

It'd all be getting eaten by zooplankton anyway.

Why on google maps when you try drop the yellow guy for street view does he just fly back to where you dragged him from?and then repeat this for ages until he either just gives up or eventually does enter street view?
You can only drop him on the roads that turn blue when you click on him.
They don't have images for the other roads so he just flies off.
Even on the blue highlighted roads he flies off probably 90% of the time!
When you click and drag the little fellow a circle appears below him, this is what you need to position over the road you want to see, not the little chap himself.

Is there a simple to use online International route finder? Like the AA routefinder, but Global.
Say I won a bit of money and I wanted to go buy a new Porsche and drive to (say) Malaysia (stopping off a few times on the way wink) could I plan my route online by typing start point: <Somewhere> in the UK, End point: <Somewhere> in Malaysia?

Which doesn't work.
Google Maps will do it for you. Not Malaysia for some reason, but works for lots of places. Reckons it will take 5 d 20 hrs for me to drive from my house to Vladivostok for example (seems optimistic). Or 95 days to walk...

If one wanted to simulate the feeling of taking off from a runway in an large aeroplane in a family saloon, what sort of bhp/ton and lbft/ton would be required?

That's the price of truth...! (I don't think he's dead, yet) But his life was over immediately.

I've never thought setting off in a jumbo felt overly special or quick.
I've a mate with an RS6, the 4.2 V8 TT so a few years old, and that delivers what you're looking for, i think!

Perhaps with the addition of a scaffold plank strapped to the roof you may get a little bit of lift as well.

I could imagine a Tesla P100D with Ludicrous mode would manage it well too.

Bing Maps is slightly better, but it only works if you break it up into separate 'legs'.

That and a bit more, it has the same acceleration as Rita Queen of Speed (linear motor launch coaster) smile

I know a few people have reported vision problems during Ludicrous Mode acceleration!

Googling seems to give a massive range for acceleration of a jet.
The feeling that is completely different is that the acceleration INCREASES over time in a plane but peaks far earlier in a car.
Regular top of the range saloon cars can easily beat most airliners 0-60 and 0-100 but beyond that get spanked - very generally.

A quick hunt gives 0-60 for a Jumbo as about 15 seconds, which even my ponderous old Passat could manage, and another 30 seconds to get up to take-off speed of ~180mph, which the Passat definitely wouldn't manage. But you'd need to build a ramp for the full 'whoops, where did my stomach go' experience.

When you think about it, the airlines probably don't want massive G-forces sending all loose objects flying to the back of the cabin.

That and the fact that you have to accelerate (in some cases) several hundred tonnes of aircraft to take off speed, the engines would have to be enormous to provide a proper kick in the back level of acceleration, they would then be very aerodynamically efficient in cruise. I suppose you could use jettisonable RATO pods...

I believe they also calculate the amount of power (%age) needed to take off on a given runway to help minimise engine wear thus maintenance and cost (fuel burn also a factor).

Or you could install a high-speed conveyor belt on the runway.

Nope, I had a tuned RS6 and even with 550 bhp it didn't match the continued thrust of a big jet.
