Michio Kaku interviewed on Fox News about Molecular Manufacturing I wonder if Kaku understands what he's saying when he says "second industrial revolution". If you count everything since the printing press, molecular manufacturing is likely NOT going to be THAT revolutionary. We've had about 4 industrial revolutions, each one re-shuffling society: Peasants; nobility ***Printing Press, ocean-going ships** Peasants/slaves; craftsmen/merchants; nobility & colonial exploiters ***Steam power & steel** Farmers & servants; factory & store workers; Capitalists ***electricity and Internal Combustion Engines** Factory & store workers; office workers; Management & owners ***Electronic automation/computers/internet** Store workers and govt dole recipients; government and management and specialists; Entrepreneurs & owners NEXT : ***Molecular manufacturing** hierarchy workers and govt dole recipients; entrepreneurs & specialists; owners & retire...

Improving Mars Direct

It should be possible to improve upon Robert Zubrin's " Mars Direct " plan: Zubrin's plan is good, but we could make the mission much safer. There are two main potential failure points in Mars Direct that are risky for humans: Will the crew vehicle be able to aerobrake into orbit and land; and will the ERV be able to lift successfully from Mars? Reduce both risks by simply not landing humans in the first few missions. Instead, land robots to be tele-operated from a Mars orbital station. Eliminating the mass of the lander and aerobraking shield allows the ship to arrive with enough fuel to get into Mars orbit using the 3rd stage rocket. Even better, use two rockets, providing backup, and to act as each other's counter-balance when rotating for artificial gravity - no need to discard the 3rd stage rockets. Instead, the crew can return to Earth on the same ship(s) in which they arrived. They just need fuel for the return trip - and Zubrin's approach can be us...

Another message on space to Pres-elect Obama

What I'm posting to Obama's new Change.gov site : Create a NEW PATH INTO SPACE, challenging NASA to begin delivering robots, equipment and materials to the moon by the beginning of 2011, using the ARES I rocket. The robots *must* be controlled by human operators on Earth, creating tremenduous flexibility. The ultimate goal will be extraction and use of lunar resources to reduce the amount of material that must be launched from Earth in the future, slashing the cost of access to space. Establish a "STEPPING STONE TO SPACE" program, in which any group - academic, commerical, or even private volunteers - will be able to purchase or obtain a grant of time using the lunar robots and equipment, or space on a robotic delivery to the moon. Announcing this early should get a lot of people excited, including small for-profit companies, if NASA establishes a series of prizes and contracts aimed at encouraging development of useful lunar capabilities. Finally, begin AIMING...
