Answer my mind teaser!

I’m not so sure. I thought perhaps that hybrids are plugged in at some point and that the mechanical power can only partially recharge the cells while driving.

That’d be worse, actually. As much energy gets absorbed as it can while the engine is running, and then the car sits there and continues to consume energy while it’s just sitting there in the garage.

It depends on the design of the hybrid power systems. According to howstuffworks, a parallel hybrid car has both power systems independently connected to the transmission. Hence, no charging of the batteries by the gasoline engine. However, a series hybrid has the gas engine running a generator, which then either powers the motor that moves the car, or charges the batteries (saving extra energy for later). A series hybrid would indeed have all of its electrical power produced by the gasoline engine.

But, either way, no extra gasoline is being expended to produce electrical power. The only energy that’s used to recharge the batteries is energy that would otherwise be dissipated as heat. So my initial point is still valid.

So what the hell did I win? I gotta have won something, fer chrissake!

So, um, Rudolph’s nose must be the same temperature as the red-hot iron, right?

And that little red LED on my power supply?

I’m sure a fictitious Christmastime character’s nose could glow at the same temperature as a red-hot iron. And something that glows because its temperature has been raised to a certain threshold cannot honestly be compared to an LED.
But I hope you weren’t serious.

Well, there you are. It’s not a question of faulty logic, but factual ignorance. How many millions of cars have alternators?

Hey, my degree’s in English so I get to misuse the terms a little ;). I’m using temperature to mean the same thing as energy levels. It takes different materials different amounts of energy to get those electrons to jump to a different orbit (same as energy level?) where the lgiht gets emitted, but the jump “red” at the same temperature irrespective of how much energy you had to throw in there. At this point someone needs to put tape over my fingers or say something about specific heat and all that.

Now, about that angels on the head of a pin question…that’d be 8. My post is my cite there. :smiley:

What, they are both hot. You grab one and you say “Hey that’s hot!” You grab the other and you say “Hey that’s hot too!”

The angels? What about the other 6? And should you really be thinking of ANGELS as hot?

You are obviously not a fan of '70’s television!

I was too young to appreciate what the show was REALLY about. Now I’m too old. :frowning:

So, the red hot coals on which one might walk to prove one’s manliness/saintliness are actually the same temperature as red hot lava?

Yup.

'Course Lava has a higher specific heat than burning wood (takes more energy to get it red hot). Which means the lava will be able to deliver more heat energy into the soles of your feet before it cools off enough to be harmless.

…is this a hijack? I’m so sorry I brought this up.

This is a highjack, and now that we are so far into it… I still don’t get how you can say that iron and lead start glowing red at the same temperature. You take a bar of iron and a bar of lead and start heating them, by the time iron is white hot and liquid the lead will only be starting to emit a reddish glow. So how does that end up being the same as them glowing at the same temperature?

I believe he is referring to the amount of heat being radiated rather than the internal temperature. Assuming that light=heat, both are only throwing off a “red” level of light, so they are throwing out the same amount of heat.

I know it’s not the correct answer, but I think he’s got a point there.

BTW, where do you work that shooting at planes is a good theoretical exercise?

Shhhhhh…let’s see if we can get clarification. Someone who’s paid to know this kind of thing is bound to wander along. I’m only 99.99999% certain I’m right, but I could be ignorant. :smiley:

But… But… But it just doesn’t make any damn sense!!! How the hell do two totally different metals… oh never mind. Stupid laws of physics are ruining this universe for me.
