    ... with many of us not realizing the importance of water, I think we have moon to look upon for our future water needs. Ah! does it mean we mean earthlings can waste water( No thats not the intent of this post).
    Read here.. water has been discovered in significant amounts on moon!
    wow!!

    It's official: There's water ice on the moon, and lots of it. When melted, the water could potentially be used to drink or to extract hydrogen for rocket fuel.....

    I suspect that, for human habitation, it's probably much cheaper to get most of the drinking water from urine and sweat. Some makeup would be needed.

    It's true we could use photovoltaics for water electrolysis and get hydrogen and oxygen for fuel. Do you have a sense of how that stacks up against battery storage in terms of weight and cost?
    Are you sure? This action cannot be undone.

    I had heard that news as well. Too bad they did not discover wine on the moon instead as it goes better with cheese (which we all know the moon is made of)... =)

    You're right, recycling human waste (including exhaled air) would be more sustainable.

    Photovoltaic is pretty attainable, though to have the required power for electrolysis would amount to very high costs. Of course, I don't think settling on the moon for the first time was meant to be an economic objective.

    I think once Helium-3 mining operations become viable, we'll see concentrated efforts from both government and private entities in solving these issues.
