Congress:Top 100:Complete List
A New Energy Congress prioritized listing of the very best energy technologies according to ten criteria, including: renewable, environmentally safe, affordable, credible, reliable, developed, and safe (among others). The New Energy Congress is an association for the purpose of reviewing the most promising claims to up-and-coming clean, renewable, affordable, reliable energy technologies, in order to come up with a weighted list of recommendations of the best technologies.
Our present focus is on the >> Top 5 Exotic Free Energy Technologies << rather than the top 100 renewable energy technologies, so the listing below is not current. We specialize in exotic, so that is where we have decided to focus.

- Noble Gas Engines >
PlasmERG's Plasma Expansion Motor - PlasmERG Inc, who is developing a noble gas plasma expansion motor providing clean, cheap, and reliable power has been selected as a top five finalist among the "Most Promising Renewable Energy Technologies" category for EE Times' prestigious Annual Creativity in Electronics (ACE) Awards.
- Top 100 / Feature: Hydro > Ocean Wave > Buoys >
Spindrift Hydrokinetic Energy Device - This ocean wave harnessing technology takes advantage of the difference between wave height on the surface versus water stability deeper down. It is a buoy system that locates the alternator in the surface buoy, with a turbine down deep, by which water is accelerated via a venture shape through which the water flows.

- Waste-to-Energy / Alt. Fuels > Diesel >
CPD Process Turns Trash into Diesel Fuel - Green Power Inc has developed a catalytic pressureless depolymerization (CPD) process they call "NanoDiesel" that inexpensively converts biomass and municipal waste into high quality diesel fuel, which could solve the world's energy and waste problems at the same time, without upsetting the CO2 balance.
This list is in a state of continual update.
Some of the best technologies are not listed here for reasons such as:
- We don't know about them yet. If you know of a technology that should (and can) be listed here, please let us know about it (submit); then be patient as we get around to evaluating it and remind us from time to time making your case, until it appears here.
- We haven't gotten around to voting on them yet. (in our hopper)
- Their owners choose not to publicly disclosed their existence yet, for strategic reasons.
- Their proprietary nature prevents the NEC from knowing enough about them to weigh them against the other technologies listed here.
- Language barriers prevent the NEC from knowing enough about them. (Translate)
- The NEC's evaluation is not perfect, but includes some technologies that are not deserving, and excludes others that are, and ranking some higher than they deserve.
That said, we are still confident that this listing is a valuable contribution toward advancing the most deserving technologies toward market penetration.
