Technological innovation

  • Building stronger, greener concrete with biofuel byproducts

    The world uses nearly seven billion cubic meters of concrete a year, making concrete the most-used industrial material after water. Even though making concrete is less energy intensive than making steel or other building materials, we use so much of it that concrete production accounts for between 3 to 8 percent of global carbon dioxide emissions.

  • New structure for regulation of geoengineering research needed: experts

    Geoengineering, the use of human technologies to alter the Earth’s climate system — such as injecting reflective particles into the upper atmosphere to scatter incoming sunlight back to space — has emerged as a potentially promising way to mitigate the impacts of climate change. Such efforts, however, could present unforeseen new risks. This inherent tension has thwarted both scientific advances and the development of an international framework for regulating and guiding geoengineering research.

  • The infrastructure of asteroid-mining economy

    An asteroid-mining space economy would be easier to build if there were the equivalent of a few Stuckey’s around out there. As is the case with other enterprises, a space economy will need fuel, liquids, and supplies, and these could be stored in outposts on dwarf planets like Ceres.

  • How to predict the progress of technology

    MIT researcher finds Moore’s Law and Wright’s Law best predict how technology improves.

  • Stopping vehicle in their tracks -- remotely

    The need to stop vehicles remotely was identified by the law enforcement community. In 2010, the characteristics of a squid’s sticky tendrils were combined with the concept of Spiderman’s super-strong webbing to create a prototype of the first remote device to stop vehicles in their tracks: the Safe, Quick, Undercarriage Immobilization Device (SQUID).

  • Using plants for herbal defluoridation of drinking water

    A filtration system based on a medicinal herb can quickly and easily remove “fluoride” from drinking water, say researchers in India. The technology uses parts of the plant Tridax procumbens as a biocarbon filter for the ion.

  • World’s first zero emission sports car is built-at-home electric car

    A new partnership has developed the world’s first build at home electric race car kit, an all-electric sports car designed and engineered to support a growing demand for zero emission racing vehicles. The iRacer kit, available from £13,999, can be transformed quickly between hybrid, pure electric, or internal combustion engines.

  • Enabling small ships to launch and retrieve long-endurance UAVs

    About 98 percent of the world’s land area lies within 900 nautical miles of ocean coastlines. Enabling small ships to launch and retrieve long-endurance UAVs on demand would greatly expand the U.S. military’s situational awareness and ability quickly and flexibly to engage in hotspots over land or water. DARPA is seeking companies to develop these systems.

  • Developing the next-generation of VTOL aircraft

    One of the greatest challenges of the past half century for aerodynamics engineers has been how to increase the top speeds of aircraft that take off and land vertically without compromising the aircraft’s lift to power in hover or its efficiency during long-range flight. DARPA’s new VTOL X-Plane project aims to achieve higher speeds, increased efficiency, and elegant design.

  • Saving money and time in developing phased RF arrays

    Phased radio frequency (RF) arrays use numerous small antennas to steer RF beams without mechanical movement. These electronics are invaluable for critical DoD applications such as radar, communications, and electronic warfare. These arrays, however, come with a high price tag. Current phased arrays are extremely expensive and can take many years to engineer and build.

  • Modified bacteria turn bio waste into fat for fuel

    “Green” chemistry developed at Rice University is at the center of a new government effort to turn plant waste into fatty acids and then into fuel. A new project aims to develop a new generation of renewable energy and bio-based products from switchgrass and forestry residues and from a new hybrid of sorghum.

  • Battle-tested technologies no employed by the police

    Technologies employed in the wars in Iraq and Afghanistan are now hitting local streets across the United States, changing how local law enforcement investigates crimes by focusing on where crimes are most likely to happen instead of where a crime has taken place.

  • New explosives vapor detection technology

    Novel explosives detection method focuses on direct, real-time vapor detection rather than collection of explosives particles. It could change paradigm for explosives screening.

  • U.S. responds to China’s cyberattacks with anti-theft trade strategy

    The Obama administration yesterday (Wednesday) unveiled the details of a broad strategy to counter the systemic theft by Chinese government agencies of U.S. trade and technology and trade secrets. The administration’s plan calls for new diplomatic push to discourage intellectual property theft abroad and better coordination at home to help U.S. companies protect themselves.

  • Chinese set to buy yet another U.S. taxpayer-backed hi-tech firm

    Lawmakers yesterday expressed their concerns about the likelihood that U.S. taxpayer dollars could end up bolstering the Chinese economy. The lawmakers reacted to reports that a Chinese firm, Zhejiang Geely Holding Group, is leading the list of companies bidding for a majority stake in government-backed Fisker Automotive, and that the only serious rival of that Chinese company is a Chinese auto maker. Fisker’s main battery supplier — U.S. government-backed A123 Systems – has already been acquired by a separate Chinese firm.
