Be Excellent To Each Other

Which one is it? That site's blocked at work.

The spider picture one is still my favourite email exchange ever.

Money
"If I had a million dollars I would buy a house with big robot legs."
After paying $7.50 for a coffee
"We should open up a shop next to that one, buy their coffees and sell them from our shop for a dollar more."
Our four door Mazda sedan
"We should paint flames on the side. Girls like cars with flames on the side. You will never get a girlfriend in a car that looks like this."
DVD rental prices
"It makes no sense, this one is four dollars for a whole week and this one is six dollars for one night. It is backwards. Someone should tell them."
After being offered a yoghurt sample in a supermarket
"She was nice, you should ask her to be your girlfriend before someone else does."
Paying for petrol
"Leaves burn, why can't we just fill our car up with them? They are free."
On being asked by a lady in an elevator what he wants to be when he grows up
"Either a model or a police sniper."
Girls
"You can't trust girls. When I get a girlfriend I am not going to tell her where I live or work."
On being told his minibike had been stolen
"I hope they are riding it and the petrol tank blows up and their legs and arms get blown off and when they are in the hospital they think 'I really wish I hadn't stolen that motorbike'."
The supermarket
"If they made the aisles wider we could drive our car in and grab things through the window and pay on the way out like at McDonalds."
Regarding me being upset over a breakup
"She was ugly and fat anyway, I dont even know how you could kiss her."
Explaining the Playstation game Grand Theft Auto 4 to his grandmother
"I don't shoot everybody, just the drug dealers and hookers."
2001 A Space Odyssey
"This movie is so boring. I would rather be staring at the wall and holding my breath for two hours."
Static electricity
"If I am standing on carpet and I get electrocuted, does everybody in the room die apart from me?"
Being told that the park belongs to everybody
"We should buy a fence and make people pay us two dollars to get in."
Relationships
"I am going to have seven girlfriends when I get older so that I can be with a different one every day and then start again on Mondays."
Swimming
"If you swim in the sea then you should always go swimming with a fat girl because sharks will go for them first."
Shoplifting
"If we went into a shop and I put a stereo on and danced, you could run out with a different stereo while everyone is looking at me."
On cleaning up
"It will just get messy again. I like it like this, it shows we have better things to do than cleaning."
Marriage
"If you get married, do you have to let your wife look at your penis?"
Super Powers
"If I could have only one super power it would be to breathe in space."
On having homosexuality explained
"That's gross. Not the bit about girls kissing girls though, that's pretty good."
School
"I don't understand why I have to go to school at all, the internet knows more than all the teachers there put together."
Religion
"If I was god I would make all the girls in the world wear no clothes."
Hygiene
"You should never wash your hands because then you will have more germs than everything else and other germs will just think "what's the point."

I can't decide whether that's a troubled genius or someone just typing the first things that come into their head.

Why can't electric cars recharge themselves? Surely it could generate more electricity than it uses, because using the electricity has to overcome the friction of the tyres on the road, but hooking up dynamos to the wheels wouldn't (it's just all spnning magnets, isn't it?)?

We should build giant fans to blow air at wind farms, using the power generated by the wind we create!

Oh my.

Look, I know it isn't the case really, but I want to know why.

Craster kept saying the same thing whilst talking about throwing himself on grenades. Doesn't make it less belmworthy.

Ok, utterly, utterly stupid question alert:

I know this isn't the case, but (a) why? and (b) IT SHOULD BE.

Ah, but, Craster was showing both a lack of common sense and a lack of knowledge of elementary physics.

Is £480pa a lot for buildings and contents insurance?

I have no idea how electricity generation works, and what sort of efficiency you get out of generating equipment. Clearly. And common sense doesn't really apply here, as it's not the sort of thing common sense can tell you the right answer to, as this is about MAGIC TECHNOLOGY.

I don't understand how you could have got the idea that dynamos won't introduce any resistance because they're "just spinning magnets". That's mostly where you've gone wrong, though.

Energy in > Energy out

No?

Energy in > Energy out

No?

I was assuming there was no reason that that would be the case. Wrongly, obv.

Some electric cars and trains do use regenerative braking, where that is used to recharge batteries while slowing the car down.

But why don't they use the spinning wheels to generate electricity when in motion?

My problem here is not understanding how dynamos work

Any energy that is used for any other purpose is energy that can't be used for its primary purpose. So if you're taking energy out to charge the battery, that energy is no longer there to be able to drive the wheels.

STOP DESCRIBING PERPETUAL MOTION MACHINES YOU BUFFOON.

Same principal as tyre grip, and why you can't go around a hairpin as quickly as you can go down a straight.

I'm merely pointing out that my problem is not the same as Craster's

It really is. Without knowing anything about dynamos, we can see that in your example, the dynamo is somehow putting out energy it isn't taking from the system. In other words, I put in E amount of energy to turning the shaft, the shaft still turns with E energy and additionally the dynamo puts out D extra energy. Which violates the first law of themodynamics, and is therefore impossible.

If the laws on conservation of energy are so strict, how do nuclear power stations work then, eh? EH?

So to get this clear, you can't have two spinny magnets making electricity?

Oh my. Have you any idea how much energy there is stored in matter, and how efficiently radioactive materials release that energy?
