Of the more than 80,000 dams in the U.S., about a third pose a “high” or “significant” hazard to life and property if a failure occurs, according to the Federal Emergency Management Agency (FEMA). The dam safety community has made a giant leap in its efficiency and effectiveness, with the implementation of Potential Failure Mode …
David Gelertner was writing about the concept of Lifestreams back in 1995 and 1996 and predicted the modern internet in the book Mirror Worlds in 1991. A lifestream is a time-ordered stream of documents that functions as a diary of your electronic life; every document you create and every document other people send you is …

We are long time members and supporters of EEBA, The Energy and Environmental Building …
A presentation included pictures of the Bangkok airport and how they use a fabric cover to reflect sunlight and control the temperature beneath it. This structure was made of PTFE and glass but the principles would still apply for ETFE and other materials. The shape of the structure traps more of the heat near the …
PTFE and PVC membranes treated with TiO² also remove significant volumes of nitrogen oxide (NOx) from the atmosphere. In this reaction between TiO² and the air, both nitrogen and sulphur oxide from vehicle exhaust emissions, are decomposed to produce cleaner, purer air; at a rate of 1.2g (NOx)/1000 m2/h MakMax Australia is working to develop …
By Alvin Wang and Brian Wang Vote for the idea of Domed Cities at the GE Ecomagination competition Over a series of articles (I will link in the other articles as they are written) we will be showing that dome cities can be made profitably and that they can provide energy efficiency and other benefits. …
