Some Links To My Work, And Interesting Works Of Others, March 2013
A Guest Post On Next Big Future by Joseph Friedlander

This is just a collection of links to my work and brief comments to aid indexing. I did not write everything linked here but am collecting the links here to aid easy finding of things.

Economics of large payloads –two published, two on the way in a 4 part series. Thanks to reader Kai Hiwatari for jogging my elbow on this subject—

The future of Computer Aided Design in 2019 and the idea of virtual wealth in a library of premade designs, which theoretically could be 3d printed into reality

A discussion (among other things) of idea of a user community of mutual inventors assisting each other (at the end, warning, very long)

My contribution to Jeff Harrow discussion about 300 mile line of sight  radius obtainable at 60000 feet from a tower or aircraft

Fun With Nuclear Engineering

Not mine but cool by Sam Cohen, designer of the neutron bomb --

Not mine but a 1964 symposium on engineering with nuclear explosives (Panama Canal 2 among others)

Engineering with nuclear explosives; proceedings of the third Plowshare Symposium, April 21, 22, 23, 1964 ([1964])

This post of mine explored a way to send probes to the stars cheaply. —The H-Cannon. Of course you may need to heliobrake at a million G’s to stop--

If Professor A.A. Bolonkin’s theories of synthesizable femtotech nuclear matter are correct here is a way to use it to colonize the Galaxy at 16% light speed.

What if we get super-tech—femtotech and the capabilities of controlled nuclear matter

Background information on femtotech by Brian covering the concept
Brian on Bolonkin paper on femto tech I helped edit

A discussion about how bad radioactive contamination can be in nuclear drainage sumps
These posts explored the potential of deuterium-deuterium (D-D) fusion and what might be possible if tritium was not required for thermonuclear power generation.

This post explored the fissionable metal requirements of an all-molten salt reactor powered world economy—

And the fissionable metal requirements of a nuclear space hopper to launch huge throughput to space easily. This post speculated on what if we just built the kind of flying nuclear reactor we could have built say in 1960 (steam rocket) versus the never built gas-core reactor in the Aldebaran and 2001 movie’s Discovery –a 12000 ton nuclear hopper.

These posts are about the prospect of space industrialization, colonization and cool mission ideas.

The idea of lunar surface rendezvous, varied lunar landers and some conversation about iron-nickle content in lunar surface material.

This pair of posts commented on the 300,000 ton a year lift model that a orbital nuclear arms race as in the movie 2001 would have required (600 Sea Dragon launches a year, or about an Aldebaran a month for that market alone)

An astonishing pdf of a 1964 Nuclear propulsive seminar from that era including a presentation by Max Hunter (not mine, but highly interesting) --If you want to know about the reactors Arthur C. Clarke imagined powering the 2001 spaceships, this was the science at the time.  

 This post examined what would happen if we had a massive lunar rock processing and materials export capability--
  This post examined the buildup to such a capability
    Keeping the lunar vacuum pristine

   This post examined what we could do by using such a capability to construct massive solar sail shipyards in near Earth space and then going out and capturing multi-million ton asteroids with solar sails the size of the planet Mercury.
Centauri Dreams covered that last article here

    And this post explored industrial processes in space (warning, very long)

This post examined the idea of using lunar industrialization to enable massive colonization—of Earth’s oceans (seasteading)

This post examined the possible effects of hyperwealth resulting from such space industrialization

Geopolitical consequences of geoengineering— Making rivers where we want them, not where the lay of the land puts them.

This post explored ways to export large mass from the earth cheaply. And remove a mass of salt like Africa from the oceans. Geoengineering over deep time.

38 percent of the world’s people live within 100 kilometers of a coast 44 percent of the world’s people live within 150 kilometers of a coast and nearly 50 percent of the world’s people live within 200 kilometers of a coast

These posts are about the ways human minds and their cognitive biases slow down the rate of possible change and technical progress.

If we could increase the incidence of genius 10 times we would live in an entirely different world. Indeed such a transition would be singularity-like, dividing history into before and after periods (and raising the interesting question of diminishing returns or no).

One can imagine an analogue to the Gates Foundation but which recruits young geniuses and guides them through the maze Charlton describes. Only a small fraction of potential genius becomes actual genius--

Joseph Friedlander's Thoughts Inspired By Alexander Bolonkin's Writings On How To Catalyze Innovation And Technical Progress

My take  on Tyler Cowen’s Great Stagnation theory
not mine but Brian’s take on Tyler Cowen’s Great Stagnation work

Long wave speculations, discussion of politics and policy etc. (Not necessarily current views, just speculation on what if this worked?) Some are quite long.
Some discussion on waste of capital lives and potential by wrong turns in history.

Existential risks (helped on English edition with Bolonkin)

(helped on English editions of below papers with A. V.  Turchin)  With original material I added in the English edition

Containing some special material I wrote gaming out theoretical strategies of hostile alien players...It is possible that when we stumble upon several different messages from the skies, which refute one another in a spirit of:

do not listen to them, they are deceiving voices, and wish you evil. But we, brother,
are good—and wise…

Other Bolonkin papers I have worked on in some (perhaps later than listed draft)
Also search arxiv for Bolonkin, Friedlander  
With Prof. Bolonkin many papers as proofreader/suggester etc but these are his papers

About me

These posts are frankly geeky compilation of various industrial, scientiic and military statistics 629 megatons of nuclear bombs have been detonated in tests. 452 megatons Soviet, 140 USA 7 megatons UK 10 megatons France and 20 megatons China. Plus under a megaton for India, Pakistan and North Korea and everyone else.

These posts are related to the Wang Bullet concept by Brian Wang which I helped develop with a great deal of back and forth. Some are written by Brian, some by me.

These are not by me but Brian Wang but are on the general topic of space and are useful to me to have here as a general orientation

(nice discussion by Goat Guy about mass driver launchers there)  1,000 GJ of energy, ten times the current engineering break-even value. The process can be repeated every 1000 sec to yield a 1 GW reactor as indicated in Figure 2 or a single DT detonation could be used to set off a 1 megaton blast using a cubic meter of liquid D2.

A “super Marx generator” ultimately reaching gigavolt potentials with an energy output in excess of 100 megajoule. An intense 10 million Ampere-GeV proton beam drawn from a “super Marx generator” can ignite a deuterium thermonuclear detonation wave in a compressed deuterium cylinder, where the strong magnetic field of the proton beam entraps the charged fusion reaction products inside the cylinder.

Brian alone on Prof Smith's work--relevant to Wang bullet g loading data

Brian Wang written and  moonbase relevant falcon heavy Timescale is about half of one second

• Human reaction time for visual stimulus is ~200 ms, ~150 ms for audio (probably smaller for haptic)
• High performance online gaming depends on latencies of less than 100-­‐200ms
• Telerobotic surgery (cutting, suturing, knot tying) requires less than 500 ms
• Telerobotic mining (driving bulldozers, drilling) assume ~500 ms
• Drone piloting with latencies of ~1000 ms (but flying is easy!)

Two way communication range within the cognitive time is 75,000km

Tying a knot with 2 seconds latency can take ten minutes

Server Sky paper by Keith Lofstrom Server Sky,  in my discussions with him it emerged that --we can harvest essentially all of the solar energy for a K2 civilization as long as it is ~15 AU or so out
