Jed sez: "The idea: you give $10 to The Time Travel Fund. They put "a percentage" of that money into a trust fund that they're maintaining. (They don't say how big a percentage. I'm guessing about 10%.) Through the miracle of compound interest, that money will turn into billions of dollars in five hundred years. If time travel is ever invented (and legal), the money will be used to pay the people who control the technology to bring the people who contributed to the fund forward in time."
Q: Will they still be using money in the future?
A: We don't know, however, it is logical to assume there will still be some form of currency used, although it will probably be electronic and not physical. We expect the fund to be converted into whatever form of currency is in use, just as all those different European currencies were turned into the Euro.

Q: What if they outlaw time travel?
A: Good question. One provision built into the fund is that it must be not only technically feasible, it must be legal as well. A maintenance fund that part of your membership fee goes to can be used to pay whatever it is that passes as lawyers in the future to try and make it legal. Laws can be changed.
(Thanks, Jed!)
