1395: "Power Cord"

In this situation, gzip /dev/inside to deflate, then pipe the compressed air to /dev/input to clean your keyboard. Avert your eyes when you do.


Something something bloatware.

anyone else being plagued by 408 errors?

Hm. I've never tried blowing into my laptop's A.C. (Air Conditioner) adapter. I've always kept my machine powered by forcing compressed air through the windmill slots in the corner.

Exhaled (and thus laden with extra carbon dioxide) air is not, of course, actually lighter than air.

Doesn't the fact that it's warmer than ambient air temperature make up for this temporarily? Balloons seem to want to upgo when I blow them up.

I only just noticed that power cord and power chord (a musical chord voiced low, particularly on an electric guitar, and typically omitting the third) are homophones. This is a phenomenon I've noticed before with baseline and bass line, and to some extent pot pourri and popery. I always wondered whether certain phonemes just go well together and are these sequences are independently coined in a kind of convergent linguistic evoloution, or whether the existence of the term in one field influences, consciously or otherwise, the coining in another.

(I realise I could google it, and probably find out as much as I could ever want to know, but that would be to deny myself the potential for social interaction.)

We don't say "power cord" so much in the UK. "Power cable" would be more common.

I giggled, although I think I would have preferred it if the laptop had whooshed off going PBBBBBBBBTTTTTTTTT and deflating.

I suppose with this there is the opportunity to make some sort of 'floating point error' pun. I don't know.
I possibly don't pay enough attention to what's going on.

On a side note: I try to inflate cats by blowing into their tails. No luck so far. However, I'm going to try with my laptop in order to increase my strike rate.

You might get better1 results with bigger cats. Their volume to surface ratio is bigger. Try tigers or lions

Well, if you can make the cooling fan turn, it'll act as a generator, dumping electrical power back into the system. (For extra credit :twisted: calculate the CFM required to meet the wattage required to keep a laptop running)

:D Reminds me of when I first started drinking in pubs: my friend and I realised that a tell-tale way to reveal your lack of experience and hence probable under-ageness might be to ask for "a pint of Bass" and pronounce "Bass" as in "bass guitar". (Interestingly Bass the beer isn't very common here, but appears to be a very successful export, though I'm not convinced it's the same beer at all).

What about this:

How much breath would it take to charge a laptop's battery by blowing into the laptop's vent and making the fan run backwards (if it contains a DC motor it wil generate some electricity)?

If the fan just sat across the power rails you might be able to power the laptop from it. But in practice there's almost certainly a fan controller in the way, so you need to push the current backwards through that, which is less likely to work. As for charging the battery, I understand that charging Li-Ion batteries is non-trivial.

Assuming we can work around that, assume your vital capacity is 4.6l (=0.0046m3) and that you can blow that through the fan in 1s. Assume also that the fan has an area of 4cm2 (=0.0004m2). The air velocity is therefore 0.0046/0.0004=11.5m/s and the theoretical available power is (1/2)x1x11.53x0.0004=304mW. Assuming perfect efficiency and a power consumption around 50W, you'd need to blow for two or three hours for each minute you wanted to use the machine.

This reminds me of the old April 1st email that used to float around the dial-up web: the phone company warned you they were going to be cleaning out their lines with compressed air, so put your external modem or PC into a plastic bag before going to bed. Otherwise, you'd risk waking up to a huge dust cloud in whatever room your computer resided. I think you were supposed to unplug your phones, too, and not plug them back in until they called to say it was OK...

Although I imagine that inflating a charging Li-ion is more of a challenge than a stationary one.

Well, sometimes it is a deliberate pun, e.g. Tyrannasorus rex, which Wikipedia describes as "a fossil beetle species from the Miocene."

Oddly enough, if you attached a laptop to a kite and attached that to the Li-ion, the laptop would only fly if the Li-ion is charging (but you'd better watch out when it starts discharging)

No man, a simple faulty charger can inflate a Li-Ion quite fast. Some would call it an explosion.

But the air is obviously stored in the battery. You're only going to get it to fly off if you short across the terminals.

It is White Beret Guy. He gets his soup out of a power outlet. You could naval gaze all day about the meaning behind anything he does, but in the end it is just silliness.

Although why the cord was disconnected from the wall rather than the back of the laptop (or both) is a bit strange. If you are using a laptop next to an outlet, wouldn't most people just plug it in? At the very least it prevents people from blowing into the other end and ruining your laptop.

That's a soup outlet. It is clearly labeled as such.
Hmm, now I want to label one of the outlets in my kitchen with "soep" (Dutch for soup).
