  • A roof paint blocks 97% of sunlight and pulls water from the air

    A roof paint blocks 97% of sunlight and pulls water from the air.

    Researchers at the University of Sydney and commercial start-up Dewpoint Innovations have created a nano-engineered polymer coating that not only reflects up to 97% of the sun’s rays, but also passively collects water. In tests, it was able to keep indoors up to 6 °C (~11 °F) cooler than the air outside.

    That temperature differential results in water vapor condensing on the surface – like the fogging on a cold mirror – producing a steady trickle of droplets.

    In trials on the roof of the Sydney Nanoscience Hub, the coating captured dew more than 30% of the year, generating as much as 390 mL of water per square meter (roughly 13 fluid ounces per 10.8 square feet) daily. This might not sound like a lot, but a 12-sq-m (about 129-sq-ft) section of treated roof could produce around 4.7 L (around 1.25 US gallons) of water per day under optimal conditions.

  • Paul McCuen – Spiral

    Taking a sliver of World War II history, cutting edge science in nanotechnology and biology, and a conspiracy of geopolitical consequences,
    Spiral delivers a smart and tense techno-thriller.

    Liam Connor, an Irish soldier who was a scientist during World War II, witnessed a horrific event in the Pacific Ocean, where the military took extreme measures to end a biological outbreak caused by the discovery of a lone Japanese sub whose crew died of mysterious reasons.

    Sixty four years later, Connor, an accomplished professor at Cornell University, is found dead of an apparent suicide. Survived by his granddaughter Maggie, grandson Dylan and close colleague Jake Sterling, Liam leaves a series of clues, knowing something might happen to him. A brutal killer follows them, in search of what Liam knew of the incident in the Pacific. Meanwhile, Robert Dunne, a national security advisor hears of Connor’s death and immediately knows what his death is related to.

    Spiral’s plot is well paced with a rising sense of tension. Seemingly random details tie in well throughout the book, and the interactions between characters and the characterization of the main characters is well done. Perhaps there isn’t nuance, but there is depth to Jake, Maggie and Robert and even a villain. McCuen isn’t afraid to kill off secondary characters in gory deaths, either, and surprisingly, the dialogue, for a debut novel in the thriller genre, flows well.

    Underlying the plot, themes of political paranoia, xenophobia and the responsibility that comes with modern science come out.
