The concrete can conduct electricity and, after being coated with organic dyes like fruit juice, produces electricity through artificial photosynthesis. It's an innovation from researchers at the University of Kassel.
The development of renewable energy is setting new records, with solar power now becoming cheaper than energy from new coal or nuclear plants. China and other players in Asia are making serious inroads into the market.
Solar panels on top, wheat and potatoes down below: researchers aim to make farmers' fields twice as productive with a revolution in power generation. A pilot facility in southwest Germany is exploring the new concept.
Solar panels on roofs are commonplace, but can the sunlight that hits building facades be used to generate power? Researchers at the University of Kassel say "yes".
After decades of relying primarily on coal-fired power, Australia has begun investing in a number of large-scale solar farms as it begins its transition to renewable energy. Economic factors are a primary driver.
