Original sentence: He calculated a power gain factor of about 30.He reported that the water temperature was raised from 20°C to about 101 °C and that the output was dry steam.Levi, an independent observer, reported that the electrical power fed to the apparatus was about 1 kW on average (although reduced to about 400 watts for a few minutes), and that it produced heat energy of approximately 12 kW which was used to evaporate water
Edited sentence: A power gain factor of about 30 is claimed.It was claimed that the electrical power fed to the apparatus was about 1 kW on average (although reduced to about 400 watts for a few minutes), and that it produced heat energy of approximately 12 kW which was used to evaporate water.The water temperature was raised from 20°C to about 101 °C and the output was claimed to be dry steam
