new sporting and events arena, the metro system is being extended and a new floodprotection system has been installed. There are downsides, of course. Rumours of corruption in City Hall are rife, affordable 6 housing remains in short supply, the health system is under strain, and traffic congestion and crime rates are up. Despite this, the mood of the city remains buoyant. Václav Havel's 13 years as president came to an end in February 2003, when his place was taken by hard-nosed, right-wing economist Václav Klaus. More change was to come: the decision on whether the Czech Republic should join the European Union was settled by a referendum - with 77% voting in favour - and on 1 May 2004 the Czech Republic became a member of the EU. However, the parliamentary elections of June 2006 ended in stalemate - it looks like a rocky
Using tidal stream generators, like wind turbines but then in a tidal stream. Due to the high density of water, about eight-hundred times the density of air, tidal currents can have a lot of kinetic energy. Several commercial prototypes have been build, and more are in development. * Wave power uses the energy in waves. Wave power machines usually take the form of floating or neutrally buoyant structures which move relative to one another or to a fixed point. Wave power has now reached commercialization. * Osmotic power or salinity gradient power, is the energy retrieved from the difference in the salt concentration between seawater and river water. Reverse electrodialysis (PRO) is in the research and testing phase. * Vortex power is generated by placing obstacles in rivers in order to cause the formation of
the setting sun, sometimes he glanced at me -- my face, my hair blowing out the open window, our hands twined together. He had turned the radio to an oldies station, and he sang along with a song I'd never heard. He knew every line. "You like fifties music?" I asked. "Music in the fifties was good.
