On March 16, 2016, an 18-meter articulated pure electric BYD bus covered the over 400 km distance between Bogota and Medellin with one single battery charge, in a non-stop test preparation journey of the BYD zero emission bus to initiate Medellin. The topography of Medellin is characterized by frequent and often exceedingly steep slopes, and this successful journey was the first step to prove BYD’s mature technology to provide reliable electrified public transportation.
A new fuel cell that transforms urine into electricity could revolutionize bioenergy production, especially in developing countries. The research work, published in Electrochimica Acta, discusses a new microbial fuel, which is cheaper, smaller in size and more powerful than the conventional ones.
A group of scientists are working to generate electricity from an unusual source: damaged tomatoes, which are not fit to be sold at grocery stores. The pilot project involves a biological-based fuel cell, which utilizes waste tomatoes discarded during harvests in Florida.
Vehicle fuels obtained from plant wastes are generally climate friendly and sustainable. However obtaining energy stored in stems, twigs, and bark is a challenging process as it is locked up in the cellulose.
A team of researchers from the Ben-Gurion University Zuckerberg Institute for Water Research, the BGU Department of Geological and Environmental Sciences, and the Israel Geological Survey have established that compared to seawater, saline groundwater obtained from coastal aquifers is a better water source for reverse osmosis (RO) desalination. The main reasons for this are the reduced pre-treatment costs and minimal membrane fouling. The research findings have been published in the Environmental Science & Technology journal.
Offshore wind turbines are constantly exposed to harsh environments and suffer the consequences. Especially their foundations, which are moored in the ocean floor. From time to time divers have to descend to examine these structures for flaws. In the future these kinds of underwater checks will become easier and faster, with the aid of newly developed sensor ring. At Hannover Messe, held between April 25 and 29 this year, researchers will be displaying a system to achieve this.
In recent years, proponents of clean energy have taken heart in the falling prices of solar and wind power, hoping they will drive an energy revolution. But a new study co-authored by an MIT professor suggests otherwise: Technology-driven cost reductions in fossil fuels will lead us to continue using all the oil, gas, and coal we can, unless governments pass new taxes on carbon emissions.
New research suggests that multi-year droughts will significantly alter the structure, composition, and dynamics of second-growth tropical forests, which have re-grown after cessation of agricultural activity or a major disturbance such as fire. These second-growth forests represent the prevalent tropical forest cover today.
Ecotourism can provide the critical difference between survival and extinction for endangered animals, according to new research from Griffith University.
Washington State University researchers have concluded that feeding a growing global population with sustainability goals in mind is possible. Their review of hundreds of published studies provides evidence that organic farming can produce sufficient yields, be profitable for farmers, protect and improve the environment and be safer for farm workers.
