SEQ. 3: BRANOVER: "Well the basic principles of the system is that a liquid metal is accelerated just because it is hot. And to explain the principle one could use the idea of a pressure cooker."
"So if that is a pressure cooker, and here you have hot water, boiling. At the moment when you open it, you getting here a very fast stream of water steam. Now imagine that instead of water you have a liquid metal. And flowing with a very high speed, you have putting a magnet with 2 poles, North and South pole. Everybody knows that from elementary physics that when a conductive media is moving through a magnetic field, electrical voltage is generated. So in our case, when a stream of liquid metal moving fast through the magnetic field, electricity is immediately generated. That is the basic principle. As you can see, there is no turbine, no generator in the conventional sense of the word, just a flow which is passing through a gap of the magnet.
And here you can see the measured voltage produced by the system."

Background: INTRODUCTION: Researchers at an Israeli University have perfected an experimental system which they claim is a breakthrough in the use of solar power. They say it halves the cost of converting energy from the sun's rays into electricity. The ten member research team is being financed by a Dutch company, and it hopes to have developed a marketable product within 2 years.
