The guts of a coal-fired power plant is a boiler, wherein coal is burned by combustion to show water into steam. The following equation shows what burning coal seems like chemically: C + O2 –> CO2. Coal is not made from pure carbon, but of carbon bound to many other elements. Nonetheless, coal’s carbon content material is excessive, and it is the carbon that combines with oxygen in combustion to produce carbon dioxide, the major Organik Gübre perpetrator in international warming.

In September of 2006, iRobot (creators of the Roomba, a robotic vacuum) sponsored an inner design competition to generate new product ideas. Jim Lynch, an electrical engineer with the corporate, determined to deal with the “dumb, dirty, and harmful” job of gutter cleansing [Source: BNet]. He began tinkering with an electric screwdriver and toy truck, and the ensuing design received the competition. One 12 months later, iRobot released the Looj, a distant-controlled robot that’s designed to motor through gutters and pitch out any debris in its path.
