Organic Rankine Cycle: Geothermal energy advantages begin to outweigh its high implementation costs

(13/08/2008)

Geothermal energy is a continuous source of energy since the heat is trapped inside the earth, without depleting. This places geothermal energy above sporadic wind and solar energy, which tends to have a capacity factor of only 20-35%; geothermal capacity is more than 70%. In the race to find alternative energy sources, geothermal energy is gaining favour. Although global energy use from geothermal sources today only amounts to less than 1%, geothermal projects now exist in around 20 countri... [more]

Osprey turbine: Osprey turbine could solve the commercial viability of tidal power

(21/01/2008)

A small team of engineers in Cornwall has made a breakthrough with the development of a turbine that they claim could solve the commercial viability of tidal power. The Osprey turbine can be used to create electricity offshore at sea or in tidal rivers and inland waterways. Following successful testing of a model rotor, a reduced-scale model prototype has been developed to assist in the design of a full-scale prototype. It is the brainchild of Fowey-based FreeFlow 69 Ltd, research and de... [more]
