While still well off the radar of most mainstream media outlets, the LENR field seems to be receiving an increasing amount of interest around the world lately. A good way to discover how much interest there is in any topic is to see how much web searching people are doing on it. Google Trends is a handy tool which measures search traffic, and the following graphic shows that interest in LENR has picked up lately.
It certainly seems that a lot of this interest in LENR has to do with Andrea Rossi's work on the E-Cat. This chart shows a comparison between searches for LENR and "Rossi E-Cat", and we see that there was not much interest in LENR until Rossi came on the scene. Since the introduction of the E-Cat, however, interest in other forms of LENR seems to have grown -- the big red spike at the beginning of 2012 is probably connected with the Joseph Zawodny video that was released on NASA's Technology Gateway web site.
Google shows that for both LENR and Rossi’s E-Cat, Sweden and Italy are the countries where the interest is greatest. Significant events are usually what drives web searching traffic, so if breakthroughs in the LENR field are reported it is likely to be continued interest — if not, things could die down again.
