Top 100 Clean Energy Technologies

Contents

http://Top100Energy.com
http://NewEnergyCongress.org

A prioritized listing by the New Energy Congress of the very best clean energy technologies according to ten criteria including: renewable, environmentally friendly, affordable, credible, reliable, developed, safe, and not encumbered by politics of science.

Caveat

This list is in a state of continual upgrade.

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 may not appear to be deserving, possibly excluding others that are, and ranking some higher than they probably deserve.

That said, we are still confident that this listing is a valuable contribution toward advancing the most deserving technologies toward market penetration.

    Nanotube Super Capacitor Battery - MIT researchers are developing a battery based on capacitors that utilize nanotubes for high surface area, enabling near instantaneous charging and no degradation. Estimating ~5 years to commercialization.
  7. Nanotech / Thin Film Solar >
    Nanosolar a leader in the drive to make solar affordable - Nanosolar has developed proprietary technology that makes it possible to simply roll-print solar cells with performance and durability similar to silicon-wafer cells, while cutting the costs, making solar affordable. The long-term limitation will be the growing scarcity of Indium. (http://nanosolar.com)
  8. Directory:Nuclear >
    Focus Fusion - Purports to be a far more feasible and profoundly less expensive approach to hot fusion, in contrast to ITER. Lawrenceville Plasma Physics' is developing the Plasma Focus Device for hydrogen-boron nuclear fusion. 4-7 years to commercial. 1 cent / kWh anticipated energy generation cost. (http://www.focusfusion.org) (NEC Specialists: Thomas Valone)
  9. Validated | Directory:Solar >
    Enviromission Solar Tower - Enviromission Solar Towers are like an inverted funnel, with a wide skirt to collect air to then turn a turbine in the tower. (http://www.enviromission.com.au/) (http://www.solarmissiontechnologies.com)
  10. Engines >
    Quasiturbine Engine - This four-chamber Wankel-like engine is capable of burning fuel using photo-detonation, an optimal combustion type. The design can also be used as an air motor, steam engine, gas compressor, hot air engine, or pump. (http://quasiturbine.com)
  11. Directory:Solar >
    International Automated Systems - Utility scale solar presently in process of being commercially installed for first time; alleged to produce electricity at 3-5 cents per kilowatt-hour. Highly-efficient bladeless turbine has wide range of waste-heat-harnessing applications. Methanol production technique will draw CO2 out of the environment, reversing global warming. (http://IAUS.com)
  12. Thermal Electric / Solar >
    Johnson Electro Mechanical Systems - Thermal energy system invented by the person who came up with the Super Soaker can achieve a conversion efficiency rate that tops 60 percent with a new solid-state heat engine. It uses temperature differences to create pressure gradients that are used to force ions through a membrane, instead of moving an axle or wheel. Inventor has also come up with an ambient energy conversion system as well as an electric heat pump.
  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.
  14. Validated | Available for Commercial Purchase | Waste-to-Energy / Plasma >
    StarTech Environmental Corp Plasma Tech - Startech is the only publicly traded waste-to-energy plasma arc technology company in the world.
