A solar research team at the University of New South Wales has converted over 40 per cent of sunlight into electricity, with an innovative take on Australian-designed solar tower technology. This is a follow up to an article yesterday about …

carbon nanotubesBoeing CEO wants Incremental Progress so that Future Moonshot Projects from Elon Musk, Google or others will kill Boeing instead of a self inflicted failed Dreamliner project

Boeing Co. Chief Executive Jim McNerney said the plane maker aims to emulate the product strategy of Apple Inc. by developing future passenger jets in incremental steps, rather than once-a-generation “moon shots” that carry too much risk. This is a …

carnival of spaceCheap high resolution thermal imaging could replace the flashlight and bring a boom in new night vision products

New, low-cost chips for sensing thermal energy could lead to a raft of new night-vision products, engineers say, ushering in everything from smarter cars to handheld devices for spelunking. A new technology used by Raytheon, “wafer-level packaging,” dramatically reduces the …
