On Friday, the BBC reported on a NASA email exchange with a space station which involved astronauts on the International Space Station using their 3-D printer to make a wrench from instructions sent up in the e-mail. Quite a marker for things to come? An object, after all, was designed on Earth and then transmitted to space for manufacture, indicating such events may have an impact on the economics of supply and demand for space missions. Astronauts would be more self-reliant on future long-duration space missions if on-demand manufacturing were in place, as an alternative to launching the actual items from Earth. NASA in this recent episode was responding to a request by ISS commander Barry Wilmore for a ratcheting socket wrench. Previously, said the BBC, if astronauts requested a specific item they could have waited months for it to be flown up on one of the regular supply flights. The BBC posed the question, "If a 3D printer can churn out something as useful as a tool in space, what else is possible?" The sky is no longer the limit. "Spare parts, components, even equipment, according to the company behind the printer, Made In Space. And that's just the start."
Given that internal combustion (IC) engines used to power automobiles are intended to drive wheels, it might seem obvious that engines which produces rotary rather than reciprocating motion in the first place would be preferable. But the reality is that piston engines have long established an overwhelming predominance in the worldwide automotive industry.
