Somebody know de price of this device? Thanks! I have one of this and is working, i’m from argentina. Somebody know de price of this device?

Devices based on these are still powering the Voyager Spacecraft 30 years after launch. It is expected that both spacecraft will continue to have sufficient electrical power to perform experiments until 2020 though each has had some instruments shut down due to lack of available power.

Though I do wonder if such a device was ever considered as an alternative or supplement to the alternator in a car. I suppose it wouldn't work well until the car was warmed up and you would still need the alternator until then to avoid having to run on the battery. But I would think that once the car was warm you could use it to provide power which would decrease the load on the alternator and thus the engine. Then again, the alternator is such a minor load it probably wouldn't be worth it anyways. A 200 HP engine is roughly, I believe, 160 KW. At maximum most alternators can't produce more than about 1500 watts (130 amp is about the biggest you will normally see and many are significantly less than that) and that's not even 1% of the engine's output. Even at lower throttle levels it still shouldn't be significant. I believe it is actually pretty inefficient.

I wonder if this was ever used with solar ? Modern photocells would be more efficient. (I HOPE!) But.... cost per watt advantage?
