Rapid growth of the world’s population, especially in coastal regions, adds pressure on resources and land already approaching their physical limits. Scientists are designing platforms to combine industry and harbour activity with renewable energy, aquaculture and leisure.
Researchers at Sweden’s Uppsala University have developed a technique to extract the lithium from spent batteries and combine this with renewable biological material, to create a battery with a similar energy capacity to that of ordinary lithium-ion (Li-ion) batteries.
Giant batteries for storing renewable energy and solar cells that can use more of the light spectrum are among the winning projects that have been awarded additional funding from the Research Council of Norway.
Studies in the 1970s showed that people couldn’t get overweight or develop cardiovascular diseases from consumption of carbohydrates such as sugar. A Norwegian professor thinks we are still paying for this mistake.
