I expect LENR technology will take off in the next few years and begin to displace carbon based energy.

We have to be able to easily shift from fossil fuels to electrics, but the infrastructure currently won't support that change. So that being said, we already have a distribution network for natural gas in the US to every home, replacing the electrical grid with home fuel cells would distribute the CO2 concentration, and distribute the water created by the process out across a larger area helping the water cycle. Recent finds of Natural Ga s in the double digit trillion cubic feet one found in Virginia and one found in ND that could handle our energy needs for the next 200 years. The next thing is to plug into the energy source at our home, no more stopping at a gas station, but that takes away a huge retail economy, and distribution points for all the other ancillary things picked up at the gas station. So there will be a push to provide natural gas at pumping stations in the future, outside that we will probably have additonal electrical distribution added because it will take too long and cost too much for every household to pay for thier fuel cell, so the utilities will add natural gas generation capabilities and pipe the natural gas to near the big cities. Natural gas the power souce for the next 100 years.

"Natural gas the power source for the next 100 years."...and THEN what????

Honestly I wish I knew - The then what, Saying that we can change in 100 years is possible, since it was about 180 years ago that steam was the prime mover then we have progressed or regressed however you wish to think about it, To what we have now. I personally would endorse high concentration living for cities, limiting their outward growth to upward growth, in addition force cities to provide a lot more of their vegetable and fruit growing on Green house floors of buildings. Going to the park, or greenhouse in the winter should be a normal activity. This would lower the transportation costs for fresh fruits and vegetables. So incremental change we need our politicians to push vertical living, in addition make the city scape so that there can be bridges at upper levels of the city as well as the lower levels. NO need to have cars in winter if you have indoor bike and walking bridges like some cities that exist Europe and the concentrated city is much more efficient, but it also requires a change in the personality of the people. are we willing to live in arms reach of our neighbors, and maybe only have 2 walls of a home have windows. I would believe that after Natural gas we will progress to microturbine generators with pulse detonation engines, that could run on any hydrocarbon source, to generate electricity that would run our vehicles when we have no charge left from the solar collector charged dynamic energy Grid. Political change - Personality change - and infrastructure change are all needed for the incremental change to be lasting.

Sorry I forgot about the Thorium and boron11 decay process, but radiation is not well understood by the normal populace. and the years of scare tactics.

¹¹B is also a candidate as a fuel for aneutronic fusion. When struck by a proton with energy of about 500 keV, it produces three alpha particles and 8.7 MeV of energy. Most other fusion reactions involving hydrogen and helium produce penetrating neutron radiation, which weakens reactor structures and induces long term radioactivity thereby endangering operating personnel. Whereas, the alpha particles from ¹¹B fusion can be turned directly into electric power, and all radiation stops as soon as the reactor is turned off.^[45]

David Arens is correct. The LENR system I am working on allows a reactor to use ordinary distilled water as both the source of H and the first stage heat transfer mechanism. The process drives P+e^-+.782MeV => n (neutrons). Hydrogen ions in the lattice accumulate the n. P or ¹H+n => D or ²H+2.2MeV. D+n => ³H+6.2MeV ³H+n => ⁴H => ⁴He+~20MeV+beta^-. Because the entire reaction runs in the solid state @ < 600C all the energy is transferred directly as heat to the lattice running the reaction. No penetrating radiation and at the end of the reactors life only a small amount of low level radioactive material remains. That material becomes completely recyclable in < 50 years. Just like the P+¹¹B reactor, in the reactor I am working on, all activity stops as soon as the power input is shut down.

What most people don't know is the only reason we don't have nuclear power based on Th now is because we (USA) needed to build Uranium based power reactors to produce atomic weapons. Now Uranium technology is firmly entrenched. A similar problem exists with tokamak VS. P+¹¹B which seems far more likely to succeed for medium to large central power stations than the tens of $BILLION tokamak style BIG science experiments. Tokamak based systems are the power of the future, and always will be.
