Of course one could use a planet to gravitationally return the crew to earth, though sustaining 20-30 g's for 20 minutes is a tad rough on the body. So we have to aero-brake as part of the turnaround (per 2010). Of course, we lose momentum. So we generate and store frictional energy in our heat shield during braking, radiating it for reacceleration after our turnaround. Only bummer is that our visit is still less than 4 hours. So we get a power rewinder for our camera! Problem solved.
It seems to me that many people are missing the point. It is useful to make things smaller, even beyond practicality, so as to explore the possibilities. Sure, this TCP/IP isn't practical. It may, however, lead to the development of minimalist stacks. Then those of us who need to connect to the net for $5 can get there. Anyone know of such a user group?
