Energy From Evaporating Water
Researchers at Columbia University have demonstrated a potential new energy harvesting technique based on the natural evaporation of water. Every day, vast amounts of water evaporate from the surfaces of lakes and rivers, a process powered by the heat energy of the sun. The amount of energy involved is enormous but generally speaking is not something we can tap into.
Floating Solar
Installing solar arrays on the surface of bodies of water is an idea that is catching on around the world. Such installations are especially attractive in places like Japan, where land resources are scarce. In the UK, there are a couple of these so-called “floatovoltaic” projects underway – one outside of London and one near Manchester.
Climate Change Redistributes Global Water Resources
Worldwide, climate change isn’t just raising temperatures, its also altering the distribution of water. So reports an inventive new study that tapped into archival water samples to reveal how sources of precipitation have changed over time.
