A submerged marine turbine to harness the energy of the Ocean

Fossil fuels propelled the Industrial Revolution and subsequent technological advances. However, our future cannot be based on them, if only because they are a finite resource; and we are very close to exhausting them. Solar and wind power is often

The innovators: US scientists harness the power of evaporating water

A small Lego device on the shelf of professor Ozgur Sahin’s office at Columbia University could open up the possibility of another form of renewable energy, and one that is much cheaper than solar and wind. Sahin has used the
