Wave power station

Wave energy is the energy contained in the movement of waves. this energy is hardly not exploited even if the seas represent 70% of the earth's surface. These vast area of water could be used to produce a large amount of clean electricity without sacrificing land surfaces.In recent years many ... »

Solar model

This solar model is a tool to predict the movement of shadows and check whether this prediction comes true. It helps to understand that the path of the sun changes with the seasons and that the design of buildings must take this into account.For architects and engineers, it is indeed very important ... »

Solar electricity storage

Unlike most energy sources, once electricity is produced it is difficult to store it. Until now, the most efficient way to store large amounts of electricity has been to pump water up into mountain dams. Electricity can then be regenerated by sending the water down through pipelines at high speed ... »

Parabolic solar Grill

Building a parabolic solar grill helps to understand the principle of sunlight concentration.   This technique is already used in experimental solar power plants. Parabolic mirrors focus the Sun's rays on black pipes in which water circulates. The heated water expands and turns into steam ... »
