  • Featured: Geothermal >
    Marshall Hydrothermal System for Harnessing Deep Sea Vents (Interview) - Bruce Marshall has filed a patent for a hydrothermal system that would harness the vast energy available from deep sea hydrothermal vents in which water seeps into near-surface magma, where it is continuously heated and ejected through vents at around 750 degrees Fahrenheit. The hot water and minerals would be brought to the surface to turn turbines. (PESWiki; Oct. 22, 2009) (Comment)
  • Top 100: Storage > Capacitors > EEStor >
    Who Killed the Electric Gas Tank? - A somewhat skeptical look at EEStor, which says they can make "power storage devices" (not technically batteries, more like peculiar capacitors) that can hold 10x more power than advanced lithium ion cells. These "electrical energy storage units" will be lighter than the most advanced batteries in the world, can charge in minutes and will last forever. (The Oil Drum; July 15, 2009)
  • Top 100: Solar > eSolar >
    ESolar expects to start up its large solar thermal plant soon - Patterned after the software startup model--selling a sophisticated computer program that drives cheap, commodity hardware, eSolar and its power plant operating partner, NRG Energy, have announced agreements with three electric utilities to install 500 megawatts of thermal solar capacity over the next few years. (MIT Technology Review; July 07, 2009)
  • 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)
  • 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)
  • Top 100 / Featured / Videos: River / Water >
    Video: Markovic Self-Propelled (SP) River Pump - We've produced a new video about Vladimir Markovic's Top 100 river pump -- a very clever, simple, robust design now going into production that can be used to pump water, generate electricity, desalinate water, all from slow-moving water without the need to build a dam. (YouTube: PESNetwork; Jan. 22, 2009)
  • 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.

  • Top 100 / Featured: Engines > Retrofits > MYT >
    Massive Yet Tiny (MYT) Engine Going to Production (Interview) - World famous inventor, Raphial Morgado, sets forth a plan for his technology roll-out without requiring auto maker's cooperation. One of Angel Labs' retrofit engines the size of an alternator could replace an SUV engine, increasing performance, and yielding mileage as good as a Prius. (PESN; January 13, 2009)
  • Top 100 / Featured: Hydro > Tide / Ocean Current >
    Marine Current Turbines' 1 MW SeaGen - SeaGen, designed and developed by Marine Current Turbines Ltd. of Britain, works in principle much like an “underwater windmill”, with the rotors driven by the power of the tidal currents rather than the wind, and has now generated at its maximum capacity of 1.2MW.
