One area of research I am watching out of curiosity is how there is more and more interest by the main stream media in LENR (Low Energy Nuclear Reaction), also known as Cold Fusion. Large organizations like NASA and others are coming forward carefully talking about research they have been performing. They're all admitting that they're seeing something, but also being clear that they're not exactly sure what they're seeing.
Here is an excerpt from an article from U.S.News & World Report entitled "New Burst of Energy Could Bring Cold Fusion to Front Burner": It's been more than 20 years since esteemed researchers Stanley Pons and Martin Fleischmann electrified the world with news that they'd observed low-energy nuclear reactions, or LENR, at the atomic level that generated excess heat, holding out the promise of "cold fusion" that did not require the blast furnace of nuclear fission as part of the energy-creating process.

Then there are also companies like National Instruments (N.I.) is among a few companies actively participating in the research of "Anomalous Heat Effects" (aka LENR or Cold Fusion) technology. The video below contains some basic background information about LENR, but also contains sales and marketing buzz from N.I.
