According to the Greek newspaper "Investors World" from march 2011 future "E-cat" devices will produce electrical power through an "inverter". Yearly cost for the production of 20 kW output round the clock(unclear if thermic or electric) will amount to 1.300 euros. "Defkalion green technologies" plans to request from RAE (regulatory authority for energy) to be included in the "renewable energy" program.<ref>[http://talefta.blogspot.com/2011/03/new-mainstream-coverage-of-e-cat-and.html Blog about the "Investors World" article]</ref><ref>[http://www.xanthipress.gr/eidiseis/politiki/6874-xynidis-ependysi-hyperion-xanthi-ydrogono-nikelio-paragogi-energeias-ergostasio-xanthi.html Coverage of the artical in "Investors World"] (Greek)</ref><ref>Article in the greek newspaper "Investors World" from March 12, 2011, Pages 20-21</ref>
