Freitas and Merkle Champion the Diamondoid Path which Drexler Now Downplays

Eric Drexler, one of the primary originators of many of the concepts of molecular nanotechnology, has written an article which clarifies his position on diamond based molecular nanotechnology. Robert Freitas and Ralph Merkle and others in the Nanofactory Collaboration have written a response indicating why they have chosen the direct to diamondoid development path. Our …

Sasol making 1.1 million barrel per day Coal to Liquid Operation in Indonesia by 2015, Competitive prices with Oilsands and Deep Water Oil

South Africa’s Sasol Synfuels has a US$10 billion project to build 1.1 million barrels per day of oil equivalent with a massive coal to liquid operation in Indonesia. Until recently coal to liquid cost $1 billion for 10,000 barrels per day of oil equivalent. So the Sasol operation is eleven times more cost effective at …

Space Elevator Tethers

The Space elevator blog discusses the needed tether strength based on work by Ben Shelef, CEO of the Spaceward Foundation: A tether which has a tensile strength of 30 GPa-cc/g would be strong enough to create a useful Space Elevator provided the Climber power system can generate at least 1.5 kWatt/kg. If the tensile strength …

Augmented Intelligence versus Democratization of the Capacity to Tackle the Big Problems

A large increase in the capability of computers to augment our intelligence and productivity is coming but the societal impact will be dwarfed by the increasing democratization of the capability of many more people to have meaningful opportunities to tackle the big problems. Intelligence and Productivity Enhancement with Computers 1. Besides the basic connection, there …

General Fusion Video and Pictures

Here is a video showing what General Fusion is doing. As previously described: if you can get within ten to hundred times the cost of regular power, you would still have huge uses for nuclear fusion. You could revolutionize space travel even if it costs more for nuclear fusion than it does for regular power. …

George Church s Roadmap to Cheap DNA Production and DNA Nanotechnology

Eric Drexler at Metamodern points out a two page roadmap to low cost DNA production by one of the top people in the field of DNA synthesis, George Church. George lays out a roadmap synthesize DNA material for dollars per kilogram of DNA. This price is about a billion times cheaper than current costs for …

Nanotechnology for Climate Control and Enabling a Kardashev Type 1 and 2 Civilization

J Storrs Hall has conceived of Utility Fog and a Space Pier and now his idea for nanotechnology enabled climate control. Version One: 1000 Times More Powerful than Global Warming You build a little balloon—my guess is the balloon needs to be somewhere between a millimeter and a centimeter in size. It has a very …

Strong Magnetic Fields Could Raise Superconducting Critical Temperature

A new-found aspect to superconductivity, called the “paramagnetic intrinsic Meissner effect,” is that a strong magnetic field could be used to raise temperatures at which materials become superconducting. A superconductor in a weak magnetic field expels the external magnetic field, but a superconductor in a strong magnetic field sometimes concentrates magnetic lines rather than loses …
