I have a friend who published a similar study with results and methodology a year ago: https://science.sciencemag.org... Still very much.a research technology, but it brings the Star Trek replicator closer to reality!

Sometimes my fingers have to touch things that aren't a keyboard or a mouse

The Chevy Volt alleviates range anxiety by including a traditional gasoline drivetrain on an EV. The new BMW i3 REx alleviates range anxiety by putting a gasoline-powered generator on an EV. What are the pros and cons of these two approaches? Do you see one of these technologies winning out over the other?

Do you feel that EVs at GM have to make design compromises because GM primary builds cars with gasoline/diesel engines? Are there design tradeoffs due to tooling, processes, production flow, etc. that GM is making that it wouldn't have to if it only built EVs?

It is your decision ultimately how you want to leave things with your daughter, but I found this anecdote of a woman who felt emotionally overwhelmed by her dead mother's letters from beyond the grave. Be wary that while your daughter may find comfort and meaning in your video letters, she may just as likely feel grief and stress: http://www.slate.com/articles/...

Both hydrogen and electricity COULD be produced from entirely renewable sources, although in the interim the hydrogen will come from natural gas (steam methane reforming), just like the electricity. The difference is that hydrogen fuel cells scale better to larger vehicles, pickups, heavy duty trucks, etc. A battery electric long haul big rig doesn't make any sense because the batteries just get too heavy.

If you could choose one robotic exploration mission that is not currently in the works, what would it be and why?

As a national leader in robotic exploration of the solar system, what do you think is the role of human spaceflight in the future? Should NASA be developing a human mission to the Moon, Mars, Europa, and beyond? How should the NASA balance the needs of good science and cost/safety issues versus the romance of human exploration?

Perhaps a good question is- will running CFD be a learning experience for your students? Will they just be blinding clicking options without getting much out of it? Perhaps they could interact with a CFD solution that you ran instead. They could still do a comparison to experimental results. I have found that simpler 2-D or other approximate codes offer better learning experiences that full-up CFD because changing options, creating geometry and viewing results is much simpler.
