Battery Power

 

  1. Battery Breakthrough -- An Update - An article appeared in the current issue of Science describing the latest in a series of recent advances that could make hybrids, and even all-electric vehicles, practical. Researchers have long known that a material based on lithium, nickel, and manganese could be used to make lithium-ion batteries that store large amounts of energy. The problem has been that batteries based on this material could be charged and discharged only slowly, otherwise the amount of energy they could store would drop dramatically. In the Science paper, researchers at MIT and the State University of New York (SUNY) in Stony Brook described a way around the problem. Read more from this Feb 2006 Technology Review article

  1. Eugene Podkletnov Anti-Gravity Breakthrough - Superconducting Force-Beam Generator produces an output in excess of hundreds of pounds of pure gravitational force.  Follow-up interview – Aug 2004, Pure Energy Systems
  2. On the Nature of Gravity and the Synthetic Gravitational Waves - A new theory is being offered according to which gravity waves are interpreted as the collective modes of vibration of virtual particles in the unit cells that constitute the crystal lattice of the vacuum.  This natural vibration (quantifiable as gravitophonons) is caused by cosmic radiation.  The task of the designer then is simple: to tap this natural vibration.  An idea is offered for the new gravitational force emitter which resolves the problem of weakness of gravitational effects produced by earlier gravitational devices. This emitter's strong effect on gravity allows for many practical applications including those in the fields of wireless communications, wireless power transmission, non-invasive surgery, and satellite launching. A Feb 2006 paper by Boris Volfson
  3. Apparatus to recover energy through gravitational force - US Patent Issued in February, 2004 - The present invention is in the field of devices for conserving energy. Among the variety of known types of different devices for conserving energy various flywheels have been invented generally to achieve two main objectives. First, a rotating object may absorb energy from a power source during the greater portion of its revolution and then deliver the energy as useful work during the remaining portion of its revolution. Second, a rotating object such as a flywheel mounted to an engine smooths out the speed fluctuations resulting from power inputs from the engine's cylinders. In each of these cases the rotating flywheel receives and stores energy, thereby conserving the energy. This invention relates to gravity operated or assisted machines for supplying, conserving, and/or recovering power, for example for the purpose of rotating a shaft, with the shaft in turn driving any of various devices including generators, displaying devices, toys, etc.

Yuanhui Zhang, an agricultural engineering professor at the University of Illinois in Urbana-Champaign, has succeeded in turning small batches of hog waste into oil, says this NG article
  6. Energy from Organic Waste - To accomplish this, three major hurdles would need to be overcome: combustible and non-combustible components need to be separated, metals and glass must be recovered, and the remaining waste needs to be converted to energy in a nonpolluting way.  Wet thermal oxidation is proposed to produce energy from waste without polluting incineration. This type of combustion has been studied extensively in connection with coal, but has not been applied to other fuels. The system would not discharge pollutants, smoke, or odors. Wet thermal oxidation can handle waste in a continuous, enclosed process with much lower pollution and higher efficiency than the “mass burn” incinerators that are commonly used now.

  4. East Japan Railway has improvised the Marunouchi North exit of Tokyo Station, a busy thoroughfare, for an experiment about generating power. In mid-October (2006), officials installed sensors in the floor under ticket turnstiles to absorb energy from the millions of footsteps of the 700,000 commuters who pass through each day. The devices convert the vibrations from each step into power by using piezoelectric elements that produce tiny quantities of electrical charge when weight is applied. Executives dream of one day using commuters’ footsteps to power information boards, lights and other devices throughout stations. The initial results from this experiment were not apparently very encouraging, generating minimal power, but it is a creative start, to say the least.
