Researchers in the U.K. and Germany have succesfully demonstrated the use of lasers to tackle radioactive waste. The researchers used a 360J laser pulse—with a duration of 0.7 picoseconds and an intensity of 5 × 1020 W/cm2—that helped form gamma rays as it ionized a gold target behind which was a sample of nuclear waste. Transmutation occurred when the gamma rays ejected a neutron from an iodine-129 nucleus to leave behind iodine 128, whose half-life is only 25 minutes, compared with 15.7 million years of iodine 129.
Engineers at Fuel Cell Energy have found a way to take advantage of a side reaction, unique to their carbonate fuel cell that has nothing to do with energy production, as a potential, cost-effective solution to capturing carbon from fossil fuel power plants.
To get to a trillion sensors in the IoT that we all look forward to, there are many challenges to commercialization that still remain, including interoperability, the lack of standards, and the issue of security, to name a few.
This is part one of an article discussing the University of Washington’s nationally ranked FSAE electric car (eCar) and combustible car (cCar). Stay tuned for part two, tomorrow, which will discuss the four unique PCBs used in both the eCar and cCars.
