Design

"Under Stratolaunch, Scaled Composites will design an enormous successor to the White Knight and WhiteKnightTwo motherships. "

The much cheaper and quicker solution would be to phone up Antonov, order half a dozen 225's (I'm sure they still have the blueprints), get out the pop riveter and bolt them together pairwise. ElReg SPB, are you listening?

Have the fridge compressor

Life?

Well, according to http://www.theregister.co.uk/2011/05/17/blighty_exoplanet/ the Gliese D environment is not unlike Middlesbrough, and consequently any life that will have evolved there will be too dumb to realise it can't have evolved, and therefore will have.

Whether they'll be dumb enough to realise you can't build an interstellar fleet without some rocket scientists around, we'll find out in a couple of decades.

Scientists probe Earth's core, make mystifying discovery

Stoneshop

Brainpower alone?

Boffin: we think the earth's core is molten iron with something else, because measurements indicate it's lighter than pure molten iron would be. Could this be oxygen?

Lab experiments ensue.

Measurements indicate that oxygen is not the other ingredient.

Boffin: well, what's ligher than iron, and abundant enough that it could account for the weight difference? Hydrogen? Nah. Carbon? Errm. Silicon? Could be, let's test.

More lab experiments ensue.

Measurements indicate that silicon might well be the other ingredient.

So, in what way exactly was this the result of brainpower alone?

With a bit of calculation, this may work

but you have to make sure the volume of the hose (and excluding those 10m that you want your remaining water column to be, ideally) is way larger than the volume of the test vessel.

Getting most of the air out using a fridge pump first, then this trick, would be most the effective way.

Using steam

means the ignition doodad will get a tad moist, then frost over as the rig gets cooled. This looks to me as being not quite conducive to reliable ignition. The rocket fuel itself may not quite like it either, and there's the bit about "cool first, suck later".

After condensing the steam

you're still left with quite a lot of air, which was inbetween the steam before it condensed

Better to let the steam condense in a cylinder with a piston, which pulls on another piston (with a smaller diameter) which pulls air out of the test vessel via a one-way valve. Repeatedly introducing fresh steam into the first cylinder, then condensing it will gradually lower the air pressure in the test vessel, simultaneously enlightening you as to why James Watt is credited as the inventor of the modern (reciprocating) steam engine, instead of Thomas Newcomen.

Fridge compressor?

A bit of searching around the web suggests they're capable of sucking about 25 inches. That's not even in the same ballpark as the air pressure at 80k feet, but I doubt that lack of air pressure would affect the firing; temperature would be the prime concern. And once the motor fires it's a self-sustaining reaction, it doesn't need outside air (that'd be quite a problem with pressures inside the motor casing being a tad unfavorable in letting air _in_). So there's probably no need to create near-absolute vacuum, and a fridge compressor would be good enough.

Have you seen web vendors *anywhere* rely on a single method of payment? Would Dutch vendors be any different? iDeal is usually just one of several methods (CoD, credit card, etc.). Also, the requirement is not that as a web vendor you offer iDeal (though you'd be daft not to), but that iDeal works with all Dutch banks that offer e-banking.

Look at those names: Jacob Haqq-Misra and Ravi Kumar Kopparapu. No-one has a name like that (let them try and get a G+ account, see how far they get), so they must be aliens themselves. Although any alien worth its NaCl-equivalent would probably have chosen a more common, inconspicuous name like Ford Prefect.

'Angry Bird' netflinger projectile brings down drug ultralights

Holmes

If there's a person at the controls

he or she will, as a matter of self-preservation, tend to try to keep control of the aircraft and put it down on the ground in such a way that it can be walked away from. Unmanned drones lack this feature, so simply noting how gently one goes *bonk* when it fails to not hit the ground is of little interest.

Ultralights

tend to be able to glide quite well without additional power. In fact, quite a few of them are some sort of deltawing glider with a small engine attached. Larger aircraft (up to 747's, as demonstrated by BA flight 9) don't quite drop straight down either if their engine(s) cut out, unless it suffers structural damage in the process and/or control is lost because there's no power to the controls.

Tossing a net into the propeller of an ultralight is pretty unlikely to make it crash.

Did *YOU* read the replies?

The big deal with batteries is that they degrade over time, and that they need a charging circuit. Capacitors don't. *THAT* is the advantage.

Nope

Capacitors and batteries are two different things. Yes, they store energy, to be delivered when needed, but they do so by a different method. It's not unlike when you need, say, acetylene: you can store it in a gas bottle (capacitor), or you can generate it when you need it using carbide and water (battery) (and a rechargeable battery is one in which the chemical process can be largely reversed by supplying energy)

Batteries vs. (super)capacitors

Yes, they're different.

Batteries, including rechargeables, and also your car battery, deliver power through a chemical reaction[ with rechargeables, this reaction is more or less reversible. You can build a simple battery by sticking a zinc and a copper nail in a lemon. It will generate power right there (enough to run a digital watch), without the need to charge it first. Problem is, over time the chemicals migrate away from the electrodes (which you need to get those lovely energetic electrons out, and back in the other side), and the battery capacity decreases. And as Murphy dictates, it will be below the required level just the moment you need it.

Capacitors on the other hand are just electron buffers. They're basically two conducting surfaces with an insulator in between. You have to apply a voltage to the electrodes to charge it, otherwise it won't do a thing. But unlike batteries, you can keep a capacitor under power and it won't (noticeably) degrade, so the moment you need the power it has stored it will deliver roughly the amount of energy it's specified for, even if it's ten years old.
