"how to make a dollar mining asteroids."

Could you elaborate? It seems to me that the time and distance of travel to the asteroid belt and back would be huge economic factors. Are there asteroids closer that they have in mind? Are they planning manned or un-manned mining missions? I have trouble seeing how the economics work here without some huge tech leap in propulsion systems.

time and distance of travel to the asteroid belt and back

Time is the controlling variable. However, the time to bring mined materials from the asteroid belt is roughly the same as the time to mine the asteroid. A delay of about 20 years would occur between beginning and first delivery. After that it would be continuous operation.
