Congress:Top 100:Complete List

From PESWiki

Jump to: navigation, search

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.

Update Notice

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.

  3. Top 100 / Featured: Ocean Wave Energy > Buoys >
    Oceanlinx Converts Wave action to Air Action - Oceanlinx is a leading international company in the field of wave energy conversion. It has developed technology for extracting energy from ocean waves by converting them into air flow that turns a turbine to produce electricity, or to provide desalinated industrial or potable grade water from sea water.

  4. 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.
  5. 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. (PESWiki; Sept. 13, 2010)
  6. Top 100 / Featured: Vortex / Hydro > Low Impact >
    Vortex-Induced Vibrations for Aquatic Clean Energy (VIVACE) - Inspired by the ability of fish to propel upstream with relative ease, VIVACE is ideal for converting natural vibrations in slow-moving ocean, river, and tidal currents into affordable and reliable energy. It is highly scalable and affordable, estimated at 5.5 cents/kw-h. (PESWiki; Dec 31, 2008)
  7. Top 100 / Featured: Wind > Vertical Axis >
    Enviro Energies' magnetically levitated Mag-Wind™ system - Affordable wind turbine design by this North American company reduces friction, noise, vibration and energy losses, and generates power in low wind environments; is now going into production. (PESWiki; Jan. 23, 2009)
  8. Top 100 / Featured: Fuel Cells / Hydrogen >
    PowerAvenue is Revolutionizing Hydrogen Production and Fuel Cell Technology - PowerAvenue Corp has patented a way to create from sand a form of silicon that reacts with water to generate hydrogen at the point of use, making silicon the energy carrier. Their fuel cells operate at low pressure and temperatures, have a high power-to-weight ratio, and are reliable and efficient. (PESWiki; Jan. 8, 2009)
  9. Top 100 / Featured: Solar > Concentrated >
    AORA hybrid solar provides baseload, community power - Israeli company combines a modular concentrated solar tower technology with other heat sources to enable its plants to be baseload capable, providing utility power needs 24/7/365. Each 'solar flower' is designed to produce 100 kW of electricity as well as 170kW of thermal power, targeting community-sized production. (PESWiki; July 3, 2009)
  10. Top 100 / Featured: Engines > Wankel >
    Regi Technologies' RadMax rotary engine - The Radmax direct-charge engine with few moving parts is based on the Wankel rotary design, but is claimed to deliver up to three times the power, with half the weight of a true Wankel engine of the same size. It is virtually vibration free and very quiet. (PESWiki; Jan. 27, 2009)
  11. Top 100 / Featured: Solar > Thin Film >
    First Solar Breaks $1/Watt Manufacturing Barrier - Though this Arizona company is to be congratulated on reducing manufacturing costs for solar modules to 98 cents per watt, breaking the $1 per watt price barrier, the environmental downside of the use of highly toxic cadmium can't be overlooked. (PESWiki; March 16, 2009)
  12. Featured / Top 100: Storage > Batteries > Sodium Sulfur >
    Ceramatec Revolutionizing Energy Storage Technology - A company in Salt Lake City is receiving widespread coverage for developing a battery system based on sodium sulfur for residential and commercial applications that may make energy storage much easier and more economical providing the tipping point to make renewables feasible. (PESWiki; August 25, 2009)
  13. 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.
