Swedish researchers have tested Rossi energy catalyst – E-cat
Researchers from Uppsala University and KTH Stockholm has conducted measurements of the produced heat energy from a device called the E-cat. It is known as an energy catalyst invented by the Italian scientist Andrea Rossi.
The measurements show that the catalyst gives substantially more energy than can be explained by ordinary chemical reactions. The results are very remarkable. What lies behind the extraordinary heat production can not be explained today. There has been speculation over whether there can be any form of nuclear transformation. However, this is highly questionable. To learn more about what is going on you have to learn what is happening with the fuel and the waste it produces. The measurements have been funded by such Elforsk.
Here is the abstract from this paper:
An experimental investigation of possible anomalous heat production in a special type of reactor tube named E-Cat HT is carried out. The reactor tube is charged with a small amount of hydrogen loaded nickel powder plus some additives. The reaction is primarily initiated by heat from resistor coils inside the reactor tube. Measurement of the produced heat was performed with high-resolution thermal imaging cameras, recording data every second from the hot reactor tube. The measurements of electrical power input were performed with a large bandwidth three phase power analyzer. Data were collected in two experimental runs lasting 96 and 116 hours, respectively. An anomalous heat production was indicated in both experiments.
