A team of researchers at Washington University led by Thomas Jarboe develops dinomak (daynomak). According to their recent statements, the reactor can provide cheaper energy cost of energy for thermal power stations.
Compared with other fusion reactors dinomak can cost ten times less and produce five times more energy. Watts of energy from the price reaches dinomaka watts from coal-fired plants, but this is possible only if large-scale production.
Referred to specific figures: gigawatt fusion reactor will cost 2, $ 7 billion, while on coal plants of comparable power will leave 2, 8 billion. Of course, this is just a theoretical calculations. Researchers have significantly improved the design, and if they receive the necessary funding, the construction of the reactor is quite possible.
Tokamaks look like empty toroidal vacuum chamber whose walls are lined with heat-resistant metal or ceramic. Outside the chamber there is a massive superconducting magnets that produce toroidal magnetic fields that confine the plasma temperature of millions of degrees.
Proposed Washington University dinomak - a further development of sferomaka, variant of the tokamak. The most important change is that it does not inherit sferomak expensive and needs to be cooled in order to achieve superconductivity tokamak magnets and magnetic fields generated by the passage of electrical current through the plasma itself.
Says graduate student at Washington University Derek Sutherland , is a challenge. To all the work, it is necessary not only the understanding of complex physical processes of plasma behavior, but also an effective way to conduct current. You can easily take away all made reactor energy back into the plasma. Such power is useless, since it produces enough energy for its own needs.
According to Sutherland, in 2012 there was a big breakthrough, then opened a new method of confinement. As a result, various techniques can achieve better than ever before, the effectiveness of current passing through the plasma and stable state synthesis in a relatively small reactor.
inspires optimism and the fact that differences in the alternative system of existing not so much. You will also need a smaller magnetic field, which will reduce the cost, complexity and size of the reactor - expensive chilled to a state of superconductivity magnets are not so easy to protect from the heat of fusion reaction.
Fred Skiff noticed that there are some unknown details that need study. You need to check the possibility of maintaining a high compression ratio and control the parameters of the plasma current and position.
The current setting of Thomas Jarboe team - a small HIT-SI3 with three magnets, its size is ten times less future commercial tokamak. 8-10 million. Dollars will allow the research team to build HIT-SIX, which will be twice the size of their current setting. HIT-SIX will work with the plasma of several million degrees using megaampere currents.
A University of Washington believed that the path to the first fusion power plant would cost only $ 4 billion, which is insignificant on the scale of other programs. We are currently working on ITER, and its original name (International Thermonuclear Experimental Reactor) best captures the essence: The project involved the United States, Russia, the EU, China, India, Japan and South Korea. The cost of ITER program is $ 50 billion.
From fusion will not be toxic wastes that need to store hundreds and thousands of years, as in the case of nuclear power plants. Thermonuclear energy is cleaner burning heat of minerals, but unlike solar and wind energy flow is stable and does not depend on weather conditions. Finally, in the foreseeable future will be no shortage of fuel for fusion reactors.
Only one problem: for all the years of research to make fusion energy for peaceful purposes to serve and failed. Work is carried out in October Lockheed Martin promised 100-megawatt reactor is so compact that it can be to carry on the truck. In June Lawrenceville Plasma Physics collected using Indiegogo money to study alternative fusion reaction proton and boron atom . Helion Energy занимается reactor that operates with a magnetic compression, and General Fusion develop reactor with acoustic waves in the liquid metal.
