Pods and Self-driving Carriages

I'm not convinced we'll only want to rent self-driving taxis.  There are benefits to having a car with personal space: leaving things in your car such as a sweater for when a restaurant puts the AC too high, or storing packages purchased in different stores while out shopping, or simply having confidence that if you accidentally leave something in the car it'll still be there when you go back.  But there's a possible compromise.  Design for separable carriage and passenger/cargo pods.  Your personal pop sits along the street or in a garage.  You order a shared carriage, then sit in your pod to relax and listen to tunes, or start working.  In a few minutes a generic taxi-carriage comes along, slides under the pod to pick it up, and drives off with you.  There would be security features so no one else can order a carriage to pick up your pod from the street (i.e. steal it).   You could order a carriage with better range for long trips - more flexibi...

Proposed Presidential Vision and Plan for NASA

Proposed Presidential Vision and Five Point Plan for re-directing NASA to more sensible, efficient and far-sighted human-in-space operations : 1) Challenge NASA with a new PLAN FOR SPACE - to begin delivering robots, supplies and equipment to the moon within TWO YEARS. The robots should be simple but dextrous, durable and repairable - in order to carry out a mission of long-term exploration, research and development focused on establishing industrial production capabilities on the moon. Since the moon is relatively close, the robots will be directly (though remotely) controlled by human operators on Earth. Controlling the robots will be tedious and slow, due to radio communication delays between Earth and the moon. But one remote controlled robot, operated in 24-7 shifts, should be able to accomplish at least as much per day as one space-suited human, and keep at it for years (with repairs), at roughly 1/100th the cost of a "manned" program and with no peril to human lif...

Safer Molecular Manufacturing Through Nanoblocks

(Copied here for 'safe-keeping', from the CRN Taskforce on Nanotechnology) Those responsible for the safety of a nation — leaders and military and police forces — might be hard pressed to deal with a world in which any weapon or dangerous device could be manufactured in large quantities at the press of a button, at the same time that economic and social norms are being overthrown by rapid change. We can expect that — by default — authorities will want molecular manufacturing (MM) to be tightly restricted — kept out of private hands, and limited to the few nations that initially have it. That approach might provide some added security — or it might simply create such incredible pent-up demand that any barriers and restrictions are quickly overcome by black markets, intellectual property piracy, rogue-nation programs to duplicate MM, etc. This essay attempts to chart a middle path for the early years of MM availability — one that allows most of the benefits of MM to be wide...
