Reduce heat, increase battery life

Message #1 - Posted 2006/11/21 - zoara

Here's an interesting thing:

In theory, this could pipe off some of that excess CPU heat and turn it into power, thus extending your battery life.

Is it like a turbo charger?

From what I've read on the link I'm not sure how their product differs from the PeltierñSeebeck effect units?

I'd like to think there was a semiconductor that converts heat directly into electrical energy then we can close down all the power stations and reduce the global temperature at the same time! ;-)

All the best ..

So are they going to use the excess heat from the processor to power it to make more heat to get more power making more heat getting... you get the idea

I wonder how long the MacBook and MacBook Pro could run with that installed, my bets on weeks... if not months

Hey, we could give it a snazzy name like 'Perpetual motion' !

Ah, if it was for Macs it would have to be called iMotion or summat? ;-)

The laws of thermodynamics called, and they want their energy back.

Well, okay, I should have guessed that the thread would go this way. :)

In all seriousness though, it does seem interesting; plenty of energy from the battery is being wasted as heat by-product. If you could tap some of that energy and turn it into electricity, then you could power the laptop with less drain on the battery, and so extend battery life.

I doubt it will be very efficient, but it should be more efficient (and comfortable) than the current leg-heater arrangement... It's just a question of whether it's economically viable and worthwhile; if it adds an extra hour to battery life and reduces leg-heating by a third, it would surely be welcome?

It would be more than interesting, but they're not doing their credibility any favours with a website like this:

But for good people to do evil things, that takes religion.

Cod, what a bad pun. BTW what's with the name change, Kyle?

Christ, it looks like a spam site.
