Popular Mechanics has a feature article on 15 new concepts in science and technology which will see public action in 2006. Among those included are
Modular Pebble-Bed Reactor : Which will make nuclear reactors cheap to make and a lot safer as core meltdown is not possible.
Nanoparticle Batteries : Which will charge from 0 - 80 % charge in about a minute.
Micro Fuel Cells: That use methanol as fuel and have twice the energy density as Li ion.
Coal Gasification : Which will benefit countries like India and China apart from the US in cleaning up coal generation and make coal generation a environmentally viable technology for a while yet.
are technologies of interest to the energy community. The storage accumalator technologies are getting exciting and will give a tremendous boost to renewable generation in just being more efficient.
