Fusion power has been about 10 years away for the last 50 years or so. Still, experts in the field have from time to time gone ahead and designed operational reactors based on then-current assumptions. One such design study was done in 1972 by staff at the Oak Ridge National Lab, reported on in early 1973. This was a 1000 megawatt commercial fusion powerplant based on the Tokamak torus-type reactor. The work was sponsored by the US Atomic Energy Commission.

A 30,000 gauss superconducting toroidal electromagnet would serve as the deuterium and tritium containment and compression field, driving up pressure and temperature to fusion levels. Neutrons spit out by the reaction would be absorbed by a thick blanket of liquid lithium; absorption of the neutrons would cause the lithium to fission and create tritium at a rate higher than tritium is consumed in fusion, thus making the system self sustaining as far as tritium. While a reactor like this, if made workable, would not have the sort of safety issues associated with fission reactors (see: Chernobyl, Fukushima), there would still be the potential issue of many tons of molten lithium. At the best of time lithium and the oxygen in air do not get along well; melt the lithium and expose it to oxygen – say, via a split weld or a broken pipe – and you’d have one spectacular magnesium-like fire that would probably reduce the entire plant (including the concrete structure) to smoldering ash.

Needless to say, no commercial powerplant like this has been built. One like it is… at least 10 years away.

Something I hadn’t noticed before: the re-entry vehicle for the Titan II ICBM nuclear warhead is, in part, translucent. It’s covered with an ablative “rubber” that is, on close examination, sort of amber-colored, translucent and with more bubbles than I would have expected from a nuclear/aerospace product.

Before the Polaris missile was developed, the US Navy studied several approaches to using submarines to launch ballistic missiles. An early idea was taken directly from WWII Germany… store Jupiter IRBMs in special canisters, towed behind subs. These would be partially flooded whe  the subs got to the launch site; this would cause the canister to tip up 90 degrees. A few hours later, the liquid fueled Jupiter would be ready to launch. Additionally, there was some thought put into the idea of installing the Jupiter vertically within subs. But nobody much liked the idea of large liquid propellant missiles in submarines. So by April 1956 the idea then moved to solid propellant rockets designed to emulate the Jupiter, carrying the same payload on more or less the same trajectory. The missile would be fatter than the standard Jupiter, but also shorter. Still, at ten feet in diameter and 41 feet in length, it was a very large missile, and only four could be carried within the body of the sub and the greatly extended sail. Fortunately, within a few months the Polaris design came on the scene, a much smaller missile made possible by both a smaller warhead and higher energy density double-base solid propellant.

A 1953 General Electric study for a Convair C-99 cargo plane modified with nuclear turbojet propulsion. The pusher-prop engines were removed from the wing and replaced with a 65,000-pound AC-2 nuclear powerplant within the fuselage. This was equipped with two separate jet engines, giving a total sea level static thrust of 35,500 pounds. Two additional conventionally fueled J77 engines were mounted in the wings for takeoff thrust. A lead and polyethylene shielded crew compartment weighing 20,000 pounds protected the crew, giving radiation doses of 0.5 roentgen per hour.

In the early 1960’s, NASA wanted the Nova rocket: a launch system capable of orbiting around one million pounds. The primary missions included manned lunar and Mars missions, space station launches, that sort of thing. But other missions were contemplated, including military missions. Information on these military missions is pretty lean. This is most likely due to the fact that Nova was a NASA project with minimal DoD input… thus there would have been minimal actual work done on military launch planning for Nova. Nevertheless, a few snippets of military Nova data have come to light from time to time.

A General Dynamics/Astronautics presentation to NASA in August 1963 had a few paragraphs and a few charts discussing military missions. Sadly there was little more; it is impossible to determine if these concepts were actually requested by NASA or not, and whether these ideas went any further. BAMBI (BAllistic Missile Boost Intercept), an anti-missile satellite system, was studied by General Dynamics at the same time as Nova, and has largely remained classified (or at least, little has been made public). Like the anti-missile satellites studied during the SDI program of the 1980’s, for BAMBI to have had a chance of success at taking out a massed Soviet ICBM strike, a large number of the satellites would be needed. In the NOVA presentation, 14 million pounds worth of satellites  – each weighing 4,000 pounds – were claimed as needed. In this case, launching 3,500 or so satellites would be a chore that Nova could handle easier than much smaller launch vehicles.

More unconventionally, Nova was also proposed as a logistics transport. In this case, it could be used to chuck a capsule across the planet sub-orbitally… a capsule with 2.5 million pounds of payload. Additionally, Nova could put a 1 million pound capsule into orbit; the capsule would de-orbit itself and land to disgorge infantry. Orbital systems were in a way prefered, as orbital systems meant that the Nova itself would go into orbit. This meant that the Nova could de-orbit on command an return to Earth at convenient locations for recovery; ballistic lobs would essentially throw the Nova away. The orbital capsule was at least illustrated with a drawing.

Finally, Nova could be used to launch offensive weapons. One million pounds were the weights given, so presumably these were meant to go into orbit. The weapons loads were remarkable, and more than a little spooky:

  • 10,000 megatons worth of nukes (speculation: 10,000 one-megaton warheads)
  • Enough chemical weapons to kill everyone in a 1,000 square mile region
  • Enough biological weaponry to kill everyone in a 1,000,000 square mile region.

Note… these weapons loads are for a single launch.

Not provide in the presentation – or anywhere else that I’ve seen – is NASAs reaction to the idea of using their rocket to launch a million square miles worth of biological horror.

I’ve made many test runs and made considerable progress. I’ve also run out of supplies and need to improve the mechanical infrastructure. so I’ve decided to sell the “prototypes” I’ve made. These are indeed  prototypes, and more to the point they are prototypes of art, so they are imperfect and variable… but they’re nevertheless pretty spiffy. These are actual cyanotype blueprints on actual vellum, an they not only look right (based on the vintage blueprints I’ve actually gotten my mitts on), they *feel* right.  The failure rate is pretty high compare to the watercolor paper, but the results are much more authentic.

I currently only have a few of each. If you would like one or more of the following, send an email stating which ones to:   On a first come first served basis I’ll pass along a paypal invoice. Postage (tubes) will be $6 US, $12 everywhere else for any number.

I will update this post with revised availability numbers. When more supplies and improved infrastructure is on hand I’ll make new prints for those that requested them.

Here’s what I have (the 12X18’s were mae two at a time on 18X24 sheets an will be sliced apart):
