The Chinese space program has made public its intention to harvest our moon's supply of helium-3 to meet China's energy needs. Other superpowers are likely to follow. While helium-3 is a great source of energy, it is not renewable. Once we use it up, it will be gone forever. We as a global civilization would be better off if we receive our electricity from natural instances of motion: solar, wind, water, and geothermal sources: basically anything that already moves and will always move on this planet for free. I would like the POW to forward this mindset to our planet's national governments. The best use of lunar helium-3 is the same as for all other non-renewable nuclear fuel sources: creating the initial spark necessary to start the magnetic sails on future spaceships. Once the magsails are activated, they will be able to remain charged and propel themselves by absorbing and redirecting cosmic and solar radiation. To those who find space exploration pointless, remember that our planet's magnetic field already has a hole and will one day, like Mars' field, deteriorate entirely, and that we owe our descendants the chance to survive the death of our planet's ecosystem.
