If this rocket motor is successful, how about mounting a VASIMR rocket motor in orbit onto a Inflatable space module built by Bigelow and a add a bunch of solar cells and create a space-tug that would move back and forth between the earth and moon?
Even if it would take a week or two to reach the moon if it can do several trips on one tank of gas it would be worth it, plus as I hear you can harvest the Hydrogen from the waste water and use it as propellant so it really could be powered by piss and vinegar. I wonder how many solar cells you would need to power it?
