What kind of energy yielding projects can be achieved in space?

fusion (H3 on the moon), solar panels

A interesting project would be to store energy using a solar panel to catch the energies of the solar wind incoming particles. I think a lot of this has already being done in Energy conversion projects.However it still need improvements.

One of the keys to the survival of humans as a species is harnessing the energy from our star. One of the things that I think is feasible is building huge solar energy converters in space so that they are in a solar orbit. These generators can transmit the generated energy by electromagnetic waves to receptors located on Earth, maybe through relays in geostationary orbits. This was the dream of Nikola Tesla. Clean energy for all.

Solar panels of course but apart frm that research is going on harnessing the energy from the cosmic particles coming from the sun as moon has no atmosphere so cosmic particles will be readily available there ... i think they will be a good source

Solar energy can be used because of the proximity to many light sources. In fact, many of the satellites that are already in orbit utilize solar power from the sun. Also, we experience "galactic noise" here on earth from the activity in space, to harness the electromagnetic portion of this noise and re-direct it could benefit us in a military environment.

Hope that's close to what you were looking for.

the one I like is fielding a huge solar pinwheel, taking advantage of the free vacuum to permit the panels to be monstrously large. Two, counter-rotating units drive a dynamo, which expresses electricity.

solar power- wind, heat and energy.
