A proposed recovery technique for oil extraction not only outperforms existing drilling and recovery techniques, but also has the potential to sequester more carbon dioxide in the process.
The first lithium-ion battery has been developed that shuts down before overheating, then restarts immediately when the temperature cools. The new technology could prevent the kind of fires that have prompted recalls and bans on a wide range of battery-powered devices, from computers to hoverboards.
adminA group of scientists has replaced diesel with kinetic energy, saving up to 20 thousand liters of fuel annually, they say, adding that this includes a series of energetically self-sustained boxes for the transport of perishable goods, with a cooling system that replaced the use of diesel with sunlight and kinetic energy.
admin< The iPhone is being used more than ever these days and with good reason. The iPhone has numerous features that most people want but they are a drain on…
adminMale moths locate females by navigating along the latter’s pheromone (odor) plume. Two strategies are involved: males must find the outer envelope of the pheromone plume, and then head upwind. Can understanding such insect behavior be useful for robotics research? Yes, according to an entomologist, whose research using computer simulations shows that such insect behavior has implications for airborne robots (drones) that ply the sky searching for signature odors.
adminMany coastal areas and harbors go almost unprotected against acts of terror. Soon a new sensor system relying on signal echoes from cell towers can quickly detect even the smallest of attack boats. This mobile radio passive radar can also help airplanes avoid colliding with wind turbines.
In the future, a wireless charging system will allow electric cars not only to charge their batteries, but also to feed energy back into the power grid, helping to stabilize it. The cost-effective charging system achieves high levels of efficiency across the whole power range, from 400 watts to 3.6 kilowatts, while the car and the charging coil can be up to 20 centimeters apart.
