Virtual reality simulations have found many practical uses - everything from helping to train military pilots to the study of the dynamics of explosives. However, now it might also coming to aid in the development of green energy solutions such as photovoltaic and wind energy plants, hydroelectric power stations and biogas plants.
Previously, when a design engineer tackled the design of such plants, he would be confronted by vast columns of numbers representing pressures, temperatures and fluid flows - the physics involved in developing a workable and safe design.
But this is now about to change. Researchers from the Fraunhofer nstitute for Factory Operation and Automation IFF in Magdeburg have developed a method that visualizes the processes inside energy conversion plants such as photovoltaic, wind, biogas and hydroelectric power stations. To do so, they have coupled 3-D plant engineering and simulation results with a virtual reality (VR) program developed at the IFF. "A special software tool has enabled us to visualize all the motion sequences for the first time ever - at just the push of a button," explained Dr. Matthias Gohla, Manager of the Process and Plant Engineering Business Unit, in a news release announcing the development.
Arrows that move through the VR model show engineers the direction in which and speed at which fluids and gases flow through a plant. Colored markings indicate potential weak points such as areas where critical temperatures, deposits or erosions could occur. Is there a potential for collisions when the plant components are moving? The virtual insights facilitate engineering and should therefore ensure that plants become more efficient and have lower emissions.
"Our VR model also helps plant operators in day-to-day operation," says project manager Dr. Martin Endig. For instance, extensive documentation may be implemented in the system. Instead of hunting through thick instruction manuals for desired information, a technician merely needs to click on the appropriate representation to obtain data on a certain plant component. Moreover, personnel can be trained to handle a plant before it is operational. Even critical situations can be simulated without endangering employees. Currently, the developers are working on another tool that notifies operators when a component is due for maintenance.
All over the country, community leaders are looking to boost economic development through various initiatives. One key element in many of those initiatives is the use of information technology. When local governments build IT infrastructure, create e-government applications, assist high-tech startups or otherwise focus on technology, they create conditions that draw businesses to their communities and help retain skilled workers. This paper discusses and provides examples of these various ways local government can use technology to ultimately make a community more attractive to businesses, visitors and residents.
