"it begins to cool down" I sense an unintended new source of air conditioning and refrigeration. Overall the idea of going beyond unity sounds pretty awesome. |

Speaking of MIT did you hear where some one on a motorcycle slapped a sticky bomb on the side of a physicist's car. |

| mr_bunny You all sicken me. This is just another socialist plot to force good, honest, God fearing, physics law abiding people to give up Edison's greatest invention. |

Majick Thise: SO our LED TV's will now need heaters to keep them warm because we left all the damn lights on again and the house got all cold. If we mix these with the hot style LEDs we can convert the waste heat of the old LEDs to light and create a set that maintains an even temp. |

I was led to believe this wasn't possible. |

Sounds like a good way to reverse global warming. |
||
| Wellon Dowd If we surround one of these with solar panels do we get unlimited power? |
||
| Honest Bender Sounds like a pretty good way to recycle heat waste. Maybe that's why anything technological always glows in sci-fi. |

Joseph Swan's, actually, but that's a rant for another day. Back to the main topic: 69 pW is a nice start but I'd rather have a multi-MW X-ray version. |

Peltier effect anyone ? A led is basicly a P-N junction... |

If we mix these with the hot style LEDs we can convert the waste heat of the old LEDs to light and create a set that maintains an even temp. Sure... but why just use them as heat sinks? Use a large batch of them to cool a device to the point where superconductivity can occur. If this leads to a fusion engine with highly efficient heatsinks, that means... BATTLEMECHS! |

At 69 picowatts, I'll only need a trillion of them to light my bathroom! |

[i.imgur.com image 640x480] Amusingly, BattleTech has had laser-based heat sinks for years... They didn't become commonplace because you light up like a beacon at night, and that tends to draw fire. |

Combine it with a solar cell, and you get infinite energy. |

| DON.MAC You know all those annoying flashing LEDs on bikes and displays and stuff. The circuit to do that was invented by Bob Widlar. There are lots of stories about Bob and so far I've never heard one where I wouldn't want to have a drink with the guy. One story is he was about to be kicked out of grad school for "insane ideas about transistors" yet he built the worlds first silicon op amp based on his idea of what is right. He seemed to disagree how LEDs work as well. LEDs hit a maximum power of maybe .5 mw until he started talking about how they really work and now they do watts not half of a thousandth. In Fark's mind, the best story is he retired and bought a decades worth of booze yet 5 years later he went back to ask for his job back. /My amp is designed by the man. It can run 150 W per channel forever. The 32 kw spikes are not problem either except to the speakers. It's the boundary cases that can vaporise wire that are a concern. |

I saw something in an Audi car brochure that suggested that the light from its headlights gets to the objects it illuminates faster than lights on other cars. |

Yeah, but by the end of the second series the story got so ridiculously intergalactic in scale that it would be tough to bring it back down to a reasonable scope. If nothing else, Brin loves to put "holy shiat, did that just happen?" moments in his books, and just to have to try to immediately top them. |

You forgot to invert the phase variance on the Hisenberg generator to compensate for the capacitance overflow from the Odeon Conduits. |

If these do work as intended, does that open the possibility for them to be used in conjunction with a high effeciency photovoltaic cell to create a machine that generates electricity directly from heat? Or am I about to be arrested by the physics police? |

picowatts? What is that in imperial? Come to think of it, is there a retarded cousin to watt? Something like pound-inch of energy? |

ZER0T0THEC0RE: If these do work as intended, does that open the possibility for them to be used in conjunction with a high effeciency photovoltaic cell to create a machine that generates electricity directly from heat? Or am I about to be arrested by the physics police? Nope, you are 100% on target. With a sufficiently efficient solar cell, and a refined system that works at lower temperatures than the current ones do you could convert heat into light into electricity, with enough electricity not only to power the initial light, but enough left over for practical use. It could be an unlimited power supply for medical implants that runs off of your own excess body heat. It could power personal electronics like watches that are always in contact with your body (and hence your body heat) anyway. They could be combined with current solar panel technology so that not only does the light the cell absorbs gets converted into energy, the heat from being out in the direct sun also becomes useable energy. The ability to convert heat into electricity without the need for things like steam turbines would be *HUGE*. |

lucksi: picowatts? What is that in imperial? Come to think of it, is there a retarded cousin to watt? Something like pound-inch of energy? 30 picowatts is approximately 40 femtohorsepower. Google suggests that I may have just made up the word femtohorsepower. /femtohorsepower |

MayoSlather: I was led to believe this wasn't possible. It's not over 100% efficient if you also count the heat energy it is consuming. However, since ambient heat is free, it's as good as 230% efficient. |
