10Top Technologies sapidity for peaches, especially rotten ones. Drapcho notes that peach waste in particular has a high percentage of sugars that can be converted to hydrogen gas. Considering approximately 20 million pounds of damaged peaches are discarded per year in South Carolina alone, her research may rial, called lignin, impedes processing into fuel. Geneticist Haiying Liang is seeking to breed poplars with a lower lignin content that could improve biofuel production and be less costly to process without harming the tree’s growth. 10. The Reverse Salt Shaker Adding just the right amount of salt is never easy, but getting salt out of water is much trickier. Large-scale desalination has long been an important method for oceangoing vessels and seaside communities for obtaining potable water. But advances in desalination technologies in 2008 and 2009 could make this a more viable, inexpensive solution for regions like the U.S. South and Southwest in search of greater freshwater resources for their growing populations. Much of the falling costs of the technology in recent years have come from incorporating reverse osmosis treatment, which lowers the temperature of the help turn crop losses into fuel. Clemson researchers also made advances this year in obtaining fuels from grasses and trees, particular fast-growing poplar trees. Cellulose is the plant material used to make ethanol. Another plant mate- desalination process and allows the plants to meet the stringent regulatory discharge requirements. Combining effluent with that of a nearby wastewater treatment plant or power plant allows the brine to dissipate to an acceptable salinity level. Just how far desalination has come was demonstrated in late 2008, when the state of California, known for its prickly attitude toward environmental threats, authorized the construction of the largest desalination plant in the Western Hemisphere in San Diego. Recycling technologies used in large naval vessels, a pilot plant in Russia is testing a small nuclear reactor for powering desalination, with cogeneration of electricity using low-pressure steam from the turbine and hot sea water feed from the final cooling system.
