If we have this kind of battery, Laptops will eat through that charge in 8 hours. I wondere how hot these babies get, though, and how much shielding they need.

IF you read the article, you would have known it does not emit heat :)

My first real C# project | Linkify!|FoldWithUs! | sighistThe reaction involved is not exothermic and therefore, those batteries aren't going to get hot. There is no radioactive emission and so that won't require much of shielding. But the question is, how far from now can we see such batteries commercially available. :sigh:

I'm pretty sure beta radiation is still radioactive emission (it emits an electron).

I must have said there is no harmful radiation.

nor does it absorb heat because it doesn't exist

"The reaction is non thermal" describes how a betavoltaic cell works: instead of using a temperature difference (like the earliest attempts at radiation powered cells did, and which seem to drive the "rat things" in Snow Crash), but like a photo cell. This doesn't mean they don't get hot. The article says Tritium is generated in the process, but from what I found, it rather makes a viable source of radiation - low energy electrons that can be absorbed easily, an antineutrino noone cares about and a half life of 12 years. The decay result is stable He-3. So yeah, there's a difference between reading and believing ;) I'm still not sure about the efficiency of the conversion, about 273rds are carried away with the neutrino, but the efficiency of betavoltaic cells I found is 6% at most. So the rest either damages or heats. I don't know if these things get hot, but I expect heat to be at least a consideration. It's quite possible, though, that it's way below the heat produced by laptops anyway. Some shielding - would still be required at least security reasons. Drop the laptop, gasp and inhale slo-mo putinium? Not good.

unless you inhale ;) and "antineutrino" sounds scary enough to get the luddite brigade up and running (I know it isn't)

All power is converted into heat when used. A radioactive power source can't be turned off. That means that if it's designed for a laptop that has a 40W maximum power need, before factoring efficiency in conversion, or the extra capacity needed initially to keep it >40W as the tritium supply is reduced it's going to be putting out 40W continuously. Your laptop will always be as hot as it is after spending an hour doing video editing even when turned off. Once hte other factors are considered it'll be even hotter than that.

If the battery is working off decay, which is happening anyway, there is no point in turning off. I think the new devices would just stay on all the time, giving instant access. However, companies aren't likely to sell many batteries, as they'd have to charge so much for them. Only going to sell 1 every 30 years or so, per device. Great for NASA or armies. Same reason we don't see cars, roads, or clothing that can last forever. Economy would fall.
