Zawodny says that the most logical first application of LENR is the home reactor, which would produce heat and electricity for the home while charging the family electric car. Another area is in transportation, with the light, portable reactors powering supersonic aircraft and flying cars without the danger or radiation. It could even be used to power a space plane capable of reaching orbit without stages or external fuel tanks.
The list of potential applications reminds me of the Fallout series of video games. For those of you who haven't played or read about the world in those games, technological philosophies stopped at around the 1950's - 1960's, e.g. once they had fission reactors they stopped looking for better methods. The games take place in the post-nuclear winter era after the inevitable global-thermonuclear war. Houses, cars and most other forms of transportation and structures all had their own nuclear fission reactors built in for generating unlimited power. Nuclear fallout shelters were placed just about every square mile and were actually just covers for running unethical scientific experiments on communities and population groups, though I suppose they did actually serve the shelter purpose as well in some cases.
