But a new study by the Harvard School of Public Health could throw a wrench in that argument, by suggesting that heat waves are deadlier than cold snaps – if true, that means the winter-time benefit of a warmer planet may be more than offset by an increase in deaths in the summer.

The British government plans to build a wave farm off the Cornish coast that could supply electricity for 7,500 homes.

Surf this: The potential market for wave energy -- electricity generated by offshore turbines -- is worth a staggering $1 trillion worldwide, according to the World Energy Council, a nonprofit research organization. In the United States alone, wave technology could supply 6.5 percent of the nation's energy. No wonder, then, that startups are rushing to stake claims before someone else drops in on the best waves.

Supplying green electricity to around 250 households with a rated power of nearly 300 kW

The world-wide first commercial breakwater wave energy plant will be built at the Spanish Atlantic coast

Designed for the waterfront in downtown Dubai, this “Wave Tower” will be located right on the water. A large undulating plane creates a bridge to the base of the tower, then folds upwards to create one of the twisting silk-screened glass sides of the structure. The “seascraper” is designed to be a green building.

The federal government is moving forward with a proposed new set of regulations for "alternative energy production activities" on the Outer Continental Shelf, including offshore wind farms and wave energy projects.

Take an artificial pacemaker. This device transmits an electrical voltage to the biological pacemaker cells of the heart. In a healthy human, these pacemaker cells generate their own action potential, an electrical waveform of about 100 millivolts. This may not sound like much energy until we remember that this electrical potential is sustained across an insulating membrane only five nanometers thick. That is 5 billionths of a meter. So the energy of an action potential is almost 20,000,000 volts per meter. Compare this to the 12,000 volts per meter at a standard wall plug. Healthy pacemaker cells spark the electrical wave that drives heart muscle contraction. When these cells malfunction, an artificial pacemaker may be implanted to take over. Waves of electrical voltage generated at the metal lead of the artificial device cross over to living tissue and initiate normal muscle contraction.
