Ever think you've invented something only to be sorely dissapointed?

When i was doing my GCSE electronics projects i had a great idea to make a set of headphones that played an inverse signal to that coming into them, making a form of sound deadening.

The tutor told me such things weren't possible and that i should think about something else. Fast forward 10 years and they're on the news

I've been thinking of an idea on making a laptop that powers it self continously without having to rely on the battery. I was thinking maybe recycling the heat energy produced during operation. I saw an article on some website about some guys in a university in the US who'd invented something that recycles heat to power so this maybe workable.

That's a good one. Haven't they been used by pilots for a long time?

That's pretty harsh.

On the bright side, there's a potential abusive phone call for you to carry out?

They've existed for ages and ages - in fact I wouldn't be surprised if they already existed 10 years ago!

Perpetual Motion

It should be possible to extend the battery life by re-using power, how much I've got no idea.

I invented the wheel

There's a big difference between thinking up a concept and actually inventing something though.

It'd still need a battery, you'd always have some heat loss and it'd never be 100% efficient.

it could be if you could find a way to bypas friction, resistance etc.

Well it wouldn't work indefinitely, otherwise that would be a perpetual motion machine. Another idea would be to generate energy from key presses and mouse clicks (peizo-electric cells under the keys?). It would have to be a crazy low-powered machine, but I'm sure it's possible in theory.

Depends massively on what area you work in. Inventing a device that needs manufacturing is different from inventing an algorithim (I really should be able to spell that).

Well i was doing the gcse course 17 years ago. The headphones started showing up for tube users and air passengers about 10 years after that.

They do a similar thing with power generation through vibration for stuff like remote sensors.

This is like a mother ******** think tank. Watch this space, OcUK is going to invent the next hoff.

Imagine a laptop made using room temperature superconductors that put thermal energy back into the battery and generated power from key presses and clicks, you could use it for days

condensation would be an issue

they existed, but they wern;t really good enough for headphones.
