rossis E cat maybe it works ?

Andrea Rossi's E-Cat (Energy catalyzer) SK model is to be demonstrated in Stockholm in January 2020. This small fusion energy device, in a box less than 12" square, is said to be able to produce electricity in a self-sustaining mode, of enough strength to fuel an electric car, for example. The end of the fossil-fuel era may be far more close to reality than we suspect.

Seems to be a scam.

In a paper posted at arXiv.org, the researchers write that, even by the most conservative of measurements, the E-Cat produces excess heat with a resulting energy density that is at least 1 order of magnitude—and possibly several—higher than any other conventional energy source, including gasoline.

+I have seen so many things like this that I will never take them serious unless they are ever mass produced. Then, maybe, I will believe.

Anyone that invests their money with someone who has served jail time....more than once....already had all the information they needed beforehand...
...and they shouldn't cry when they lose every penny.

The history of 'Snake Oil' scams, and the public's amazing willingness....even their 'need' to believe....is a fascinating study of human nature.
