How can we generate artificial sunlight on moon ?

Question

if we need to cultivate a crop then we need proper sunlight. in this context , how can we generate artificial sunlight.

what is the principle of hydrogen cells? can anyone explain in detail?

Answer 1

You can use light bulbs, as on Earth.

During the day, you can use sunlight.

Fuel cells use a catalyst to extract electricity from hydrogen and oxygen.  On Earth, you can use air for oxygen, just as you do with gas burning engines, so you only need hydrogen.  But in space, you need to carry both.  The result is water, which you can drink.

Answer 2

You only need artificial light during the two-week long lunar night. You'd probably just charge batteries with photovoltaic chargers (solar power) during the day, and then discharge the batteries to make light at night.

There's oxygen on the moon, but it's part of the lunar rock (Al2O3, FeO). I suppose you might be able to extract the oxygen chemically with solar energy (or nuclear energy), or with plant photosynthesis. The major problem to lunar gardening is the shortage of water and nitrogen.

There's supposed to be water in some of the polar craters, but it's sort of dispersed in the moon's soil, like permafrost. To get the water out, you'd have to cook the permafrost, and you could use solar power for that. But that still leaves the nitrogen problem. The moon doesn't have much of that.

Answer 3

Why would we want to.

There is no atmosphere to grow anything in!

In any case, plenty of research labs use sodium lamps indoor to grow plants - so I don;t think we do need "real" sunlight. Photons are photons - so why do they have to be solar in origin?
