are actually real businesses with real revenue, as opposed to all the penniless start-ups that foamed up the markets during the dotcom boom.But just because the rise in tech IPOs has been slower doesn’t mean we’re headed in the right direction. The slow but steady climb in tech listings over the past few years has been accompanied by a sharp drop in U.S. listings overall, making tech IPOs a bigger part of the U.S. game. From 1995 to 2010, listings on U.S. exchanges dropped from 8,000 to 5,000, while the number of listings on non-U.S. exchanges grew from 23,000 to 40,000. As more emerging markets, especially in Asia,[url=http://www.ocosound.com/]Christian Louboutin Discount[/url], diversify out of bond markets, fixed income, and currencies into equity positions, they’re turning to familiar, more local exchanges to raise capital. Except when it comes to tech.As more foreign companies go global,[url=http://www.ocosound.com/]Cheap Christian Louboutin Shoes[/url], the U.S. has become a global tech magnet. The number of Chinese tech companies listing on U.S. exchanges, for instance, has more than doubled over the past few years. Why? Because foreign companies think American investors have a sweet tooth for tech. U.S. exchanges tend to offer deeper pools of capital for tech investments than other international exchanges, where investors tend to be more conservative. Even the London Stock Exchange,[url=http://www.ocosound.com/]Christian Louboutin Sale[/url], a popular destination for foreign IPOs,http://www.ocosound.com/, is known for its stodginess compared to the U.S.Amid tougher global competition, U.S. exchanges see their tech-savvy rap as an opportunity for growth. Last year, thanks to an intense PR campaign in Silicon Valley, the NYSE won more than 40% of the U.S. tech IPO market, up from its average of 12% from 2000 to 2008. The strategy may up its profits for the next few years as more foreign tech companies cash in on U.S. markets, but it’s an iffy endeavor for the U.S. economy long-term. Just like with any portfolio, if U.S. exchanges put all their eggs in one basket, they increase market risk.New Technology that Could Reduce Your Gas and Electricity ConsumptionGas and electricity prices have remained steady for a while now but as surely as the seasons change, you can expect utility prices to fluctuate over the coming years. One of the inescapable facts is that gas and electricity supplies will not last indefinitely. The hunt for alternative technologies has been going on for decades but two exciting innovations could provide genuine renewable alternatives that could help reduce our dependency on fossil fuels.The first innovation is called the Anaconda. Developed by a team of British scientists, Anaconda looks like a long, black rubber tube � because it is a long, black rubber tube! The sea snake is deceptively simple but harnesses the power of wave energy through a clever manipulation of the movement of waves.The Anaconda lies in the water just below the surface of the water. The black rubber tubing is filled with water with a turbine at one end. As waves roll over the Anaconda, they create a bulge of water within the tubing which is then forced down the length of the tube towards the turbine. With constant wave fluctuations, the bulge gathers kinetic energy which then drives the turbine as the water bulge is pushed through the end of the tube.The real benefit of the Anaconda is that there are no mechanical parts, so it requires very little maintenance and there are very few things that can go wrong with such a simple system. The rubber material used to make the device is also naturally resistant to erosion which makes it long lasting. Best of all, wave energy is constant and reliable unlike other sources of renewable energy such as wind and solar power, which means the Anaconda provides a realistic alternative to our consumption of gas and electricity.The second innovation is a power storage system which provides a reliable substitute to back-up power systems. Energy needs to be stored in huge batteries for times of peak use. With conventional batteries though, the efficiency of such storage systems is very low and storing energy costs a lot of money and electricity to power air-conditioning systems which
