Technology: IAS Closed-Loop System

Closed-Loop System: Another IAS Landmark Breakthrough!

IAS achieves annual solar-to-electric efficiency ratio of nearly 24%, far higher than competing energy sources - This means IAS can generate electricity at breakthrough low costs while conserving water, a crucial added benefit with groundwater levels around the country sinking.

The third party engineering review was conducted by reputable engineers with Ph.D. and M.S. degrees in Physics, Mechanical Engineering and Nuclear Engineering from prestigious Universities such as M.I.T., U.C. Berkley, U.C. Davis, and DePaul. Collectively, these scientists have many years of accumulated specialized expertise in optical engineering and efficiency, thermal dynamics, combustion stability, liquid rocket engine performance, system optimization, mechanical and fluid systems analysis, solid and gel propellant performance, structural dynamics, rotating machinery and vibration with application to turbine blade rubbing. This review supports that the IAS bladeless turbine and solar panels meet and in some cases exceed all performance and efficiency projections. Perhaps the most telling outcome of this independent engineering review was the conclusion that the IAS bladeless steam turbine can operate as a part of an overall closed-loop system or as a stand-alone component.

The composite analysis also supports that compared to other solar technologies the IAS technology has a higher overall annual efficiency factor than photovoltaic (PV), traditional concentrated solar power (CSP) such as towers and troughs, and is better or comparable to CSP dish technology.

The net conclusion is that based on the functionality and the low-cost design, an IAS solar thermal power plant needs to convert only 5% of the gross annual solar energy hitting its panels to electricity in order to compete with the lowest priced solar technology available today. An IAS solar thermal power plant has an annual solar-to-electric efficiency of nearly 24%, almost 5 times the level needed for IAS technology to compete effectively!

Solar Plant: Water is heated to about 1,800 degrees by the sun through the solar lenses and heat exchanger. This super heated pressurized water then goes to the IAS turbine, and by means of steam, the turbine turns, creating electricity. After this process, the steam condenses back to water by a Steam Condenser and finally through a High Pressure Pump the water is reclaimed and reused. Thus, the process is repeated over and over. This is called a Closed-Loop System, so vitally important in conserving precious water resources in desert areas.

Groundwater levels around the country have been sinking as wells for drinking water and irrigation pull water out of aquifers faster than they can naturally recharge. Now, using gravity-measuring satellites, NASA and California researchers have documented the extent of water loss in California's Central Valley, and the results are not good.

The measurements show the amount of water lost in the two main Central Valley river basins within the past six years could almost fill the nation's largest reservoir, Lake Mead in Nevada. The total is about 30 cubic kilometers; one cubic km contains more than 264 billion gallons of water.

IAS technology could help communities conserve precious water resources and help some states meet legislative mandates to begin generating in 2010 and beyond an increasing percentage of their electricity from renewable sources, while conserving declining water resources. In the state of California, for example, the state legislature has required that 10% of all public utility power must originate from renewable sources in 2010, and this percentage requirement increases each year all the way up to 33% by 2020.  Therefore, it is clear that demand for renewable energy will soon be reaching a fevered pitch with highly populated areas of the southwest! 

IAS Technology Eliminates Need for Expensive Cooling Towers

Cooling towers are a critical component of traditional turbines to help maintain the Balance of Plant. Because of the unique nature of IAS's turbine, the actual working chamber can be used as both a direct heat exchanger and water recovery system on the condensing side. This eliminates the need and the significant cost of a cooling tower.

The proprietary IAS bladeless turbine can recycle water in a closed loop. This is a perfect fit for the areas of the Southwest where water conservation is very important. Also, the excess heat that is normally wasted in the cooling towers can instead be put to some other use. Heat storage and other heat byproducts can increase the efficiency of the plant from 20+ percent up to 70 percent.

The absence of expansion tanks, traditional turbines, and cooling towers not only significantly reduces the overall cost of equipment and installation, but also reduces daily operations and maintenance costs which translates into a lower wholesale price for electricity per kWh produced.

Other Components OF IAS Technology

The sun doesn't shine at night, nor can you create solar energy on cloudy days. Therefore, what do you do to produce power 24/7? IAS has a number of ways to do this. You need some way to heat water to create the steam to propel the turbine. Using natural gas is a viable partner to the IAS solar technology at some potential sites. Below is the inner working of the IAS Burner System. Many things can be used in the Burner System. The most promising are biomass products. These products also qualify for a 30% tax credit. Any plant or vegetation can be used, for example. There are three specific and quite interesting projects being considered, each with a different biomass product. First, west Texas offers cotton residue that can be used to produced 100 megawatts of power along with solar energy. Second, algae can be cheaply grown in Tennessee where the price offered per kilowatt hour is quite high. Third, pig manure. Yes, pig manure! This is likely the best of all, because it's been reported that the burning of pig manure could potentially satisfy 25% of the peak energy needs of America! But first, a process must be developed to remove water from the manure to make it combustible. IAS has done it! Imagine burning pig manure to produce clean renewable energy. There is a huge pig farm in the Milford, Utah area that will likely be used by RaPower3 and IAS for a 24/7 renewable energy project.
