2000-07-07 – Adaptive optics and your sunglasses

Adaptive optics, in a nutshell, are lense systems and mirror systems which adapt to correct for errors in transmission. An example of this is heat haze. The shimmering of what you are looking at is caused by the movement and changes in the properties of the air, and a fast computer, some expensive systems and […]

2000-01-14 – Time Domain Reflectometry

Time Domain Reflectometry TDR is the process of taking a fibre-optic cable, shining a light down it, and being able to tell where problems are, even before the cable is broken. All the equipment needed is an oscilloscope, a fast photodiode and a fast light source. Fibre optic cable works due to internal reflection. This […]

2000-01-13 – Space – the final frontier?

Space – the final frontier? Mass-drivers A mass driver is a device for throwing stuff. If you like, it is a BFG-9000. It uses pure energy or a chemical reaction to throw a lump of whatever. In my opinion it is the best solution to thrust in space at the moment, and with re/supply of […]

2000-01-12 – The King of Tonga

The King of Tonga Some twenty plus years ago, a utopian group decided they were going to set up a haven, and tried that a couple of decades ago. They put a pile of rocks and a flag pole on top of a submerged mountain in the mid Pacific. They intended to set up a […]

2000-01-11 – Further tests of stability

Further tests of stability Well, further tests on the structure reveal the incredible stability of this system. Each plastic cup holds 240ml, or 240 grams worth of air, whilst only weighing 4.24 grams. The mass of the glue used is very low, and will be reported when I have measured it, but as it is […]

2000-01-09 – The OTEC problem

Ok, confession. I don’t know much about this, however… (Go here for detailed OTEC stuff about heat exchangers, closed vs. open-cycle, etc.) OTEC needs the cold water from the deeps to act as a heat sink to extract heat from the warmer surface water. Basically a giant solar collector in the form of the surface […]

2000-01-08 – The Floating Island problem- Fish farming and Murder

Ok, so.. The problem with Utopian societies is that people aren’t Utopian. Where you have more than one person, you tend to get tension. Eventually, given enough people, you get crime, and murder. Now, crimes of passion are one thing, but delibrate murder is something that is, to my mind, less likely to happen if […]

2000-01-07 – The Floating Island problem- Law and Order

The system may have to be thought up from scratch, but my suggested starting place is the work of the Founding Fathers of the United States of America. Based on individual freedoms, with high individual responsibility, and low government intervention and low taxes, Oceania will be a strong, stable, two-house democracy. Here are some of […]

2000-01-06 – The Floating Island problem- Waste services

In the beginning, human wastes will not really be a problem. However, as Oceania grows, the lack of land-fill, and the hope that we can be both economically viable and also have a low impact on the environment means that a solution will have to be found. Given that the entire system is being built […]

2000-01-05 – The Floating Island problem- Growth, Layout and special structures

The following is a postulated first growth design. Key: Firebreaker Cellular heavy lift Extra structures In this diagram, the engineering area has been moved in to attach directly to the main area for support, and additionally some blocks have been replaced by heavy lift blocks (8) using the cellular construction bottle technique outlined earlier. In […]
