(Natural News) Fuel cell technology has been around for some time. The first truly modern fuel cell vehicles came from the 1950s and 1960s, when they were used on experimental vehicles such as the 1966 Electrovan, a van which was outfitted with a fuel cell that took up so much space it could only fit two people. Fuel cell technology was even […]

(Natural News) A transportation company is betting that its new oversized drone will, within 10 years, take to the skies as a cargo transporter, a flying taxi or even an air ambulance. The company, Alaka’i Technologies, unveiled the passenger-carrying model of their “oversized drone” near Los Angeles. They call it the Skai (pronounced “sky”), a drone with […]

(Natural News) You’ve heard of all the ways to convert light or wind or heat into usable electricity. But have you ever thought that the coldness of the universe might serve as an alternative source of clean and renewable power? Most energy production systems get their power from somewhere. Solar panels collect light while wind […]

(Natural News) Experts know that a strange species of bacteria found in oxygen-deprived sediment and soil can generate electricity. But they only recently learned that the microorganism achieves this through a method that differs from that used by other electric bacteria. Called Geobacter sulfurreducens, the anaerobic bacteria possess a unique biological structure. This previously unidentified feature makes […]

(Natural News) Most water harvesting systems collect precipitation such as rain or water droplets from fog and other low-lying clouds. But a new device developed by Chinese researchers can get it directly from the atmosphere, provided there is sunlight. The new water collection system features nano-composite foam made from graphene. It relies on sunlight to power […]

(Natural News) Caffeine helps boost the energy levels and mood of coffee drinkers. But did you know that it could also improve the performance of a new generation of solar panels? Researchers reported that coffee’s primary stimulant increased the efficiency of perovskite photovoltaic cells, an alternative approach to solar power. When bolstered by caffeine, perovskite […]

(Natural News) Need a cheap yet reliable way of purifying water without resorting to dangerous chemicals? Russian researchers have discovered the potential of graphene as a material for making water safe to drink. In their experiment, graphene treated water by trapping bacterial cells. The nano-material assembled into flakes that were easy to remove from the […]

(Natural News) When it comes to cancer, early detection can often mean the difference between life and death. One of the most promising developments in cancer detection can be found in nanotechnology, and gold nanoparticles in particular could prove to be a life-saving tool. Nanoparticles are already used in certain types of medical screenings and […]

(Natural News) Swedish researchers are keen on recovering as many resources as possible from waste products. One of their latest research projects promises to come up with a way to free useful chemical compounds from biological waste. In this context, biological waste refers to unwanted organic waste products from the agricultural and food industries, such […]

(Natural News) There are rocky exoplanets around the size of Earth that lie within a few light-years of the solar system. While these relatively nearby worlds receive intense radiation from their active stars, they might eventually bear alien life – if they haven’t already done so. These planets lie well within the habitable zone of […]
