Questions raised anew about space elevator stability
As we place more systems in space — soon, perhaps, weapon platforms to counteract China’s growing anti-satellite warfare capabilities — there is a growing need to service and maintain these systems; one way to do so relatively on the cheap is to build a space elevator, but the stability of such an elevator is raising questions

New generator for wind turbines
To connect to the National Grid, large turbines often use a doubly fed induction generator (DFIG) system comprising brushes and slip rings; these require regular maintenance which can be difficult to carry out, particularly offshore or in poor weather conditions; U.K. researchers offer solution

Cat's eyes locate things underwater
A new underwater cat’s eye can reflect back a tuned signal, revealing its location, to existing sonar systems; new device does not use batteries — and it does rely on toxic chlorofluorocarbons (CFCs)

Benefits and risks of close science-defense collaboration
This week was National Science and Engineering week in the United Kingdom — and the London events and exhibit emphasized the contribution scientists and engineers make to the defense of the kingdom; a venerable engineering magazine says we should be just a bit cautious here lest we turn the battlefield of the future into a publicly funded industrial testing ground, where commercial pressure would overwhelm the sober considerations of defense decision makers

Fence to nowhere
DHS received the keys from Boeing — behind schedule, it should be noted — to Project 28, only to find out that it fell short of the promise the department made to Congress, and that Boeing made to the department; Boeing has now received a three-year extension; the Arizona Republic says the failure of Project 28 has deeper meaning for technology and policy

DHS defends handling of Project 28
Project 28, built by Boeing along twenty-eight miles of the Arizona-Mexico border, was meant to showcase advanced border security technologies which DHS would use in the more ambitious $8 billion border surveillance system along the U.S.-Mexico border; DHS initially said that the project’s technology failed to deliver on its promise, and gave Boeing a three-year extension; DHS now defends its handling of the project
