Dario studied software engineering at the Polytechnic University of Turin. When he isn't writing for Gizmag he is usually traveling the world on a whim, working on an AI-guided automated trading system, or chasing his dream to become the next European thumbwrestling champion.
A highly ambitious proposal recently advanced by Samsung describes the deployment of a huge network of 4,600 near-Earth satellites that would provide internet coverage on a truly global scale. The artificial constellation would more than double the number of working satellites in orbit around our planet and lead to low-latency and (potentially) low-cost access to about 200 GB of internet traffic a month for up to five billion people, no matter their location.
Researchers at MIT and Tsinghua University in China have found a way to more than triple the capacity of the anodes, or negative electrodes, of lithium-ion batteries while also extending their lifetime and potentially allowing for faster battery charging and discharging. The new electrode, which makes use of aluminum/titanium "yolk-and-shell" nanoparticles, is reportedly simple to manufacture and is especially promising for high-power applications.
Scientists at Northwestern University and the U.S. Department of Energy have found that perovskite cells, one of the most promising solar technologies of recent years, can repay their energy cost over 10 times faster than traditional silicon-based solar cells. The finding confirms that, once issues related to cell longevity are ironed out, perovskite cells could soon bring us solar energy on the cheap, and do so with less impact on the environment over their lifetime.
Researchers from Germany, Japan and the United States have managed to create a tiny, reliable transistor assembled from a single molecule and a dozen additional atoms. The transistor reportedly operates so precisely that it can control the flow of single electrons, paving the way for the next generation of nanomaterials and miniaturized electronics.
Researchers at MIT have developed a new type of flexible, nanowire-based
supercapacitor with performance vastly exceeding its graphene
counterpart. It could find use as the ideal energy source for the next
generation of fitness trackers and other wearable devices.
Scientists at the Korea Advanced Institute of Science and Technology (KAIST) have developed an omnidirectional wireless charging technology that can charge multiple devices at once, at a distance and, crucially, at peak efficiency regardless of which way the devices are facing. The technology, said to be safe for humans, is set to be trialled in cafes and offices and could allow for much more convenient charging of mobile devices.
A California startup is seeking funding through Kickstarter for Dot, the "world's smallest Bluetooth headset." The device reportedly measures only 13.8 by 21 mm (0.54 by 0.83 in), weighs just 3.5 g (0.12 oz), and smashed its modest funding goal only one hour into the campaign. Its diminutive size, however, comes at the expense of battery life.
University of Cambridge researchers have discovered that a material already known for its peculiar electrical properties appears to behave as both a conductor and an insulator at the same time. This find could represent the discovery of an entirely new class of materials, challenging our current understanding of how metals behave.
A photoelectrochemical cell (PEC) is a special type of solar cell that gathers the Sun's energy and transforms it into either electricity or chemical energy used to split water and produce hydrogen for use in fuel cells. In an advance that could help this clean energy source play a stronger role within the smart grid, researchers at the University of Texas, Arlington have found a way to store the electricity generated by a PEC cell for extended periods of time and allow electricity to be delivered around the clock.
The stand for the region of Liguria at the Milan 2015 Expo features a project as bizarre-sounding as it is intriguing: an attempt to grow crops underwater, inside air-filled biospheres. It's part of an effort that could prove a low-cost, low-energy solution to grow food in parts of the world where this was not previously possible.
