A protoype aims to solve the EV charging problem with a completely innovative charging system: cars can be recharged while traveling on highways equipped with dedicated systems that allow battery charging while the vehicle is moving.
The use of energy-efficient production technologies can reduce global CO2 emissions by eight gigatons per year - which is nearly twice as high as previously assumed. Achieving this requires, at the least, that already existing efficient technologies are made available and used worldwide.
Wind energy has become an integral part of the energy supply. A new milestone for the transformation of energy supply systems was reached last year with renewable energy now accounting for 29 percent of the gross energy consumption.
Energy is the most important resource for humanity and solar energy is the ultimate energy source. The sun as a solar energy source has a number of advantages: it is abundant, it is essentially inexhaustible, and it doesn't discriminate but provides equal access to all users.
In a new study, chemists boosted and analyzed the unprecedented catalytic activity of an element called vanadium for hydrogenation - a reaction that is used for making everything from vegetable oils to petrochemical products to vitamins.
The same technology that adds fizz to soda can now be used to remove particles from dirty water. Researchers have found a technique for using carbon dioxide in a low-cost water treatment system that eliminates the need for costly and complex filters.
Solar power can cover up to 40% of the electricity needs of a typical Belgian household. Going beyond that level becomes really expensive: using batteries coupled with solar panels would be twice as expensive as using the power grid.
