Wave energy is produced when electricity generators are placed on the surface of the ocean. The energy provided is most often used in desalination plants, power plants and water pumps. Energy output is determined by wave height, wave speed, wavelength, and water density. Waves are generated by the wind as it blows across the sea surface, so that energy is transferred from the wind to the waves. Wave energy is sometimes confused with tidal energy, which is quite different. Waves travel vast distances across oceans at great speed. The longer and stronger the wind blows over the sea surface, the higher, longer, faster and more powerful are the waves.

CVD Vale is developing a new synthetic diamond drill bit for the Brazilian pre-salt drilling operations which will soon be tested by Petrobras.CVD Vale is a Brazilian company located in São José dos Campos in the State of São Paulo. They specialize in manufacturing high grade synthetic diamonds for industrial use. Next month two CVD Vale prototype diamond tipped drill bits will start being tested by Petrobras at selected pre-salt plays. According to company founder Vladimir Airoldi.” We´ve made synthetic diamond fillings produced from gases for the drill bits, a pioneer initiative in the world”. According to Airoldi, the big differential with this technology is the greater durability of the drill bit…
