I figured that we would start off this topic in particular to address power systems that could be used without fear of dwindling sources. Please post any information relative to renewable energy that could be applied to Europa.

Solar Energy is plausible, but remember - sunlight is less concentrated upon reaching Europa, and we would need vastly greater amounts of panels than on Earth.

Nuclear Energy is another source of power. It is, so far, the most efficient method of energy that we have. These would be built for extreme conditions, such as those present on Europa.

Water Power is plausible, depending on the presence of current below Europa's surface. Perhaps this could be used?

Radiation Conversion is another option, as radiation is of heavy presense in the area. If beta radiation is present enough, the emitted electrons may be able to be converted to energy. Just a thought.

Any other ideas, anyone?

Energy could be generated by tapping into sulfuric acid deposits in the crust?

The new small nuclear reactors could give abundant power and require minimal maintenance/construction on site.

I agree that nuclear reactors are of huge potential for such an undertaking.

Using sulfuric acid deposits would be good, although I question the efficiency and scale of resources available.

I agree. With present technology, I don't see any viable alternative to nuclear power.

A couple of these dropped onto the surface before arrival would be nice.

Getting to Europa nuclear is currently the best option I think, but using radiation as a means of propulsion might be better if possible. Also on the surface you will want a few energy sources for 1: the communications system (either in orbit with or on Europa) 2: any probes that will be used both on and below the surface 3: The base camp and 4: the submersible since these 4 will probably be separated for an extended amount of time. Just some things to think about.

Nuclear reactor recuire fuel. Nuclear fuel. We can't take it from Earth, and, for certain, can't find it on Europa's surface. Most of all processes in Space take energy from thermonuclear synthes, reaction of hydrogen, but for this reaction we recuire plasma. I think problem of plasma less difficult, than mining nuclear fuel, aspecially know that Europa havn't it.

I disagree, Most... We could bring Plutonium-238 nuclear batteries (quite a lot of it) and those would be more than sufficient... the Voyager-1, which left earth almost 30 years ago, is still running on them...

How many of these batteries would we need?
I guess we would need a lot more than Voyager - how much power can they deliver ?

I think the Nuclear Batteries should be a backup plan. It would be better to invent some "real" renewable energy source for the mission.
