I've not seen anyone address the issue of cooling. If you run a turbine, you need water and you need to cool the steam that flows thru the turbine, which means lots more water. That means scaled up versions of these plants need to be near lots of water.
Math and science come together in many ways in engineering. The history of engineering has many examples that relate to the life of every kid. I've read several fascinating books on this and would recommend one with many short explanations about key people in this process, but can only recall it was written by the dean of a major engineering school. Browsing through engineering books in an engineering school library would be helpful. A great many are listed by alibris.com and other book search engines, but I'd want to see what's inside before buying. Wikipedia might help with references, too.
The writing part might be integrated in several ways:
--Kids write letters to engineers and engineering organizations requesting information
--Have kids write about projects they find using the internet and searching for 'engineering for kids'
--Have kids write reports about how things like baseball bats, wheelbarrows, escalators, pyrex, chain saws, car jacks, storm forecasting, bicycles, etc were developed
--Several books on engineering math for kids are listed by amazon.com. Books reports on such books by students would combine what you seek.
Brigham Young University has pursued the idea idea of speed learning with software that
allows speed viewing of digital video tapes of lectures, as well as
speed listening at
http://www.enounce.com/docs/BYUPaper020319.pdf
The work is dated and I've seen nothing else since, but the idea of providing presentations
as videos or audio recordings for review by students who can select, speed up, and extract what they need
should have merit.
Here's a quote I picked up a few years back's:
"Apparently, American Psychological Association research has shown
that while listening to a speaker, people do the following things:
*18% are really listening to the speaker
*25% are having erotic thoughts
*57% are thinking about something else
(Note: I say "apparently" because I read this in a handout I got at
the CPSI conference, and haven't been able to find any actual
confirmation of this research on the APA site.)
Most people can speak about 150 words per minute, but can hear and
comprehend 900-950 words per minute. So after the first 20 seconds or
so of a presentation, the audience will fade in and out and think
about other things. So, we were told, you can make this work in your
favor by drawing a line down the center of your notepaper and
recording "in" thoughts on one side, and the "out" thoughts on the
other side. This is supposed to free you from trying to remember "out"
thoughts, and encourage you to generate ideas without losing track of
the presentation. http://www.corante.com/ideaflow/

Others have noted some web sites of possible value. Here are several more:
I'd like to see some US cities do this, like LA, then a state, like Calif, and eventually expand the model country-wide. That's where we are going anyway, it looks like, except for really heavy needs where fiber is still necessary, such as trunk lines.
Also back in the 70's I heard some comments during a seminar at the Armed Forces Institute of Pathology, Walter Reed Hospital, that tests performed on cats brains indicated a buildup of toxins, not oxygen deprivation caused brain death.
Somewhere recently a recommendation was made for CPR that you have a 70% better chance of surviving a heart attack if only chest compressions are used, instead of compressions plus the usual lung inflations. Is the reason due to oxygenation, toxin removal, or a combination due to more time spent on compressing the heart.
The 40MW a year breaks down to 4.56 KW an hour and that would be about what a home needs, right? The linked article doesn't give the square footage of this installation. I'd like to know what that is, too.
Photogrammetry covers this type thing and it is used in police work periodically, but requires a tripod for the camera and a plumb bob to mark the spot on the ground below the camera, the camera height, and inclusion of a known-sized placard or piece of paper a foot or two square in each photo.
Practically speaking it's too complex for police work and certainly open to challenge in court along the lines of many comments made here by slashdot-ers. Google photogrammetry for lots more details.

Ok, so now we've an airplane made of this. What happens if it crashes and catches fire?
