Some business run by irish/jew are not open to non irish/jew. But that's considered normal. If WASP are discriminated, it's OK. If a minority is discriminated, it's suddenly not OK. I fucking hate progressist sjw ethics...
My point exactly. If you need between 30W and 35W during a 6 month span, 10 years from now, you just scale the RTG to deliver that output when you'll need it. You can also scale the RTG down a bit, and compensate with batteries. Experiments runs from batteries. When the batteries run low, you stop experiments for a while while the batteries get recharged by the low-power quasi-continuous RTG.
A few more number, the previous was only accounting for the weight of the fuel. Voyager's[0] RTGs were 37.7 kg including about 4.5 kg of Pu-238. It included 3 of those for a combined total output of 470W electrical, at launch. This makes each RTG to produce 156W. Given that Philae would only require 32W, and assuming the weight of the RTG is proportional to the weight of the fuel, it could be made to weight 9.2kg... with 1970's technology.
[0]: Mars Curiosity was also including a RTG, but I can't find any number concerning its weight / output.
Can't you use tax money for better things than playing with remote machine on comets ? I don't know, maybe reducing your debt, or feeding the poorest ?
I'm calling bs on your statement, could your provide a reference ? That would be utterly stupid. The only reason you'd have a single size would be if you were producing millions. Here, we are talking about one unit every few years.
The solar panel were designed to output 32W at 3AU. Assuming the probe can run on that power, that's merely 64g worth of PU-238 (0.5W/g). Though, this is its thermal output. If you consider that Seebeck generators have a 10% efficiency, you could get 32W electrical out of 640g of PU-238. Let's account for the 10 years trip, so let's make it 1kg.
I'm pretty sure the solar panel and batteries are heavier... And the wonderful thing ? You can power the probe continuously !
This is only because of precaution-principle aficionados, gaia loving, "activists" who objected to both the building of new, safer, reactors and reactor design research.
Most women are lazy. They should at all price stop sexy women depiction. These women are sexier than they will ever be [without effort]. By removing this content, they expect their men to get frustrated, and crawl at their feet, and obey their every whim. It's just a power struggle between women.
Of course many women have too much power. The only fact of having a vagina means they can control men who want to have access to that vagina. Most men are submissive by nature, and it is the worst, weak, kind of submission. Women might not be on board of directors, but they can control things backstage.
I have no problem with discrimination. I'm not gonna hire a ugly women for a public relation/customer facing position. Just the same, I don't expect to be hired in a startup where all the frat nerds founders are into binge drinking, or in a startup made out of moms&pops.

I'm living about 9000km from my hometown. Wake up... You ain't happy ? MOVE.
It's the usual evil Caucasian young male argument, mortal enemy of the fascist sjw... nothing new.
At least, 6' of snow don't fall on the city overnight...
I see you are an idiot.
Classical SJW bully tactics. You don't agree with me ? You are either an idiot, or you are suffering from a mental illness. [sic]

When men will let female be taller.
I do... when their plan is to cut my balls.
There is something strange. Voyager's RTG seems to have been more efficient (37.7kg for 150W output) than Curiosity's one.
"Nuke" has a clear meaning. It not only implies nuclear fission/fusion, but nuclear fission/fusion used in a military context. Which is not the case.

Solar, on the other hand, is clean and wonderful...
Yeah, solar lead to a multi-billions program working for what ? 60h ? That's a heck of an hourly fee :-/
Can't you use tax money for better things than playing with remote machine on comets ? I don't know, maybe reducing your debt, or feeding the poorest ?
Then you modulate the amount of Pu-238 with this short lifespan in mind.
Given that Pu-238 is only emitting alpha particle, there isn't much to be worried about, unless you start ingesting it.
I'm calling bs on your statement, could your provide a reference ? That would be utterly stupid. The only reason you'd have a single size would be if you were producing millions. Here, we are talking about one unit every few years.
If the comet hit earth, a few kg of PU-238 will probably be the least of our worries...

We're talking about PU-238, not the abundant U-238... Though, I agree, your point remain.
Your lack of knowledge on PU-238 is disappointing...

I had the mistaken belief that all space probes / landers were nuke-powered.
Plutonium-238 is not weapon grade... So it would never have been "nuke-powered".

And yes, I do believe my word.
