Chinese students develop a microbial fuel cell that can generate 80 hours of electricity by adding a spoonful of sugar. Sharon Reich reports.
An autonomous 'nuclear battery' displayed at the 2017 Atomexpo exhibition in Moscow on Tuesday can provide power for a period of around 50 years. Developed by the Lutch Research Institute which is affiliated with Russian state nuclear corporation Rosatom, the battery may revolutionize the stored energy market and even the very concept of batteries. The Rosatom nuclear battery, whic is based on the isotope of nickel-63, is set to undergo several years of testing.
This is the B-Droid, a brand new quadcopter drone with a special extension which is designed to polinate flowers. That's right, the long, metal rod with a fluffy yellow fabric is designed to carry pollen and transfer it to blooming flowers in the spring in light of the world's declining bee population. Begun in 2012, the project is financed by the National Center for Research and Development in Poland. Scientists at the Warsaw University of Technology showcased their B-Droid drone prototype at their lab on Friday. As the name suggests, the B-Droid acts as an artificial honeybee which helps out in the pollination process. Scientists are able to control the drone remotely and can pilot the quadcopter to precisely deliver pollen to many different types of flowers. Various versions of the drones exist to pollinate different types of flowers with widely varying shapes and sizes. Scientists indicate the type of flower they want to pollinate and the B-Droid identifies the appropriate flowers in the field before transfering pollen to that particular species. Could this be the answer to declining bee populations?
