A Problem With Wind Power [] [click here for printerfriendly PDF]by Eric Rosenbloom Wind power promises a clean and free source of electricity that would reduce our dependence on imported fossil fuels and the output of greenhouse gases and other pollution. Many governments are therefore promoting the construction of vast wind "farms," encouraging private companies with .
This amounts to a length change of centimeters for every meters of concrete subjected to a rise or fall of 38 degrees Celsius. Thermal expansion and contraction of concrete varies primarily with aggregate type (shale, limestone, siliceous gravel, granite), cementitious material content, water cement ratio, temperature range, concrete age, and ambient relative humidity.
· The electricity flows through an inverter to power the home, and the excess feeds into the electrical grid. Heat produced in the cycle is transferred through a system for home and water heating. Right now, the fuel cell system works best in larger homes, about 3,000 square feet and larger.
