- Green
Steam Energy - Robert Green, an American Inventor, has developed a
brand new technology which generates kinetic energy through the
conversion of waste heat (as well as many other fuel sources). The Green
Steam Engine is piston powered and designed for a wide assortment of
practical applications. These steam engines are easy to build and can be
used to power boats, electricity generators, air or water pumps, water
distillers, heat pumps, air conditioners and a wide array of other small
to medium sized appliances. Read more from this blog article
- Reclaiming
Corn Drying Energy - The methods of reclaiming heat energy fall into
two distinct categories; (a) heat recirculation and (b) the use of heat exchangers.
Heat recirculation works best on continuous flow dryers operated to dry
and cool simultaneously. Heat exchangers, however, can be used on either
continuous-flow or batch type high-temperature dryers. Read more from

- Some Thermally Activated Technologies Info given at this
US
Dept of Energy web page - The key thermally activated technology
(TAT) program areas are: Absorption chiller and heat pump technologies,
solid and liquid desiccant VAQ (ventilation air quality) technologies,
heat and mass transfer (energy recovery and recycling), thermal storage
and thermal management technologies, advanced heat-driven power cycles
(Organic Rankine Cycles, Stirling Engines) and adapting these to IES
applications.

- System and Method for Recoverying Geothermal Energy and
for Converting Recovered Geothermal Energy into Useful Power - This
research has been developed by Charles J Mankin Ph.D., University of
Oklahoma, Office of Technology Development. Fore more details, see here
- Multiple-completion geothermal energy production systems
- Document Type and Number: United States Patent 3957108 - Abstract: A
system for the mining of geothermal energy in which a plurality of
geothermal wells radiate from a single surface site into a subsurface
geothermal reservoir. From Free Patents Online
- Method for locating and evaluating geothermal sources of
energy by sensing electrostatic voltage gradients - from Free Patents Online
- Geo Heat Center Quarterly
Bulletins @ Oregon Institute of Technology
- System and Method for Recoverying Geothermal Energy and
for Converting Recovered Geothermal Energy into Useful Power - Attempts
to recover this energy by utilizing active sites close to the surface
such as fault lines and igneous rock flows of molten material have
resulted in obvious problems. This invention presents a system and
method for recovering geothermal energy and for converting recovered
geothermal energy into useful power in stable subterranean formations.
See the University of
Oklahoma page for more details
- Method for locating and evaluating geothermal sources of
energy by sensing electrostatic voltage gradients - United States patent
- Abstract: A method and apparatus for locating and evaluating
geothermal sources of energy wherein it is known that the earth has
electrical currents and that these currents are reflected in
electrostatic voltage gradients above the earth with magnitudes in
proportion to the magnitudes of adjacent subterranean geothermal
sources, characterized by detecting the voltage gradients; individually
recording the voltage gradients; and evaluating the recorded gradients
for determination of the location and potential of adjacent sources of
geothermal energy. More details from the Free Patents Online

- Geothermal power – clean, silent electricity from out of
the ground - Geothermal power generating plants, which make use of the
planet’s interior heat, are becoming increasingly popular around the
world. Research is still being carried out into the most efficient way
to extract the heat but commercial plants are already in operation. Read

- Hole in the ground for transfer of geothermal energy to
an energy-carrying liquid and a method for production of the hole - US
Patent Issued in December, 1999 - Inventor(s) - Einar Langset -
Application - No. 875449 filed on 1997-08-28 - Abstract - A hole in the
earth for transferring geothermal energy from the earth around the hole
to an energy carrier fluid which is introduced into the hole. The lower
ends (7, 8) of at least two substantially vertically extending hole sections
(2, 4) which have been used as wells for the recovery of oil or gas, are
interconnected via an additional hole section (3). More from this Patent Storm page
- Deep Heat-exchangers to Mine Geothermal Energy - A
project in Aachen, Germany, hopes to challenge this trend by using a
deep geothermal heat-exchanger to extract heat from far beneath the
earth’s surface, through a borehole 2.5 kilometres deep. Heat abounds at
this level the planet over, but up until recently engineers have lacked
the means to bring the valuable resource to ground level without a
dramatic drop in temperature. Technicians at Aachen have diminished this
obstacle by using one borehole instead of the two separate holes (one
for hot and one for cold water) employed in previously inefficient
attempts elsewhere. This method could allow this vast source of
renewable energy to be tapped effectively all over the world - read more

- Conversion of geothermal energy from subterranean
cavities - United States Patent 4297847 - Inventor(s) Clayton; Carl C.
(Corpus Christi, TX) - Abstract: Geothermal energy is recovered by (1)
introducing into a subterranean heat exchange medium which is in heat
exchange with a high temperature formation a liquified vapor which will
vaporize at the conditions of the medium; (2) vaporizing the liquified
vapor; (3) confining the liquified vapor until pressurized; and (4)
recovering pressurized vapor having thermal and pressure-volume energy
converted from the high temperature formation. Read more from this Wiki Patents page
- Recovery of geothermal energy - United States Patent
4030549 - Inventor(s) Bouck; Larry S. (Tulsa, OK) - Abstract: A
subterranean formation is penetrated by a borehole. The formation is
fractured and propped with a slurry capable of maintaining a thermit
reaction. The slurry is ignited. Upon cooling, a solid metal conductor
fin network from the bore into the formation is formed in the fracture
system. Energy is transferred between a locus in the borehole and the
formation by the network. Read more from this Wiki Patents

About Oilgae - Oilgae - Oil & Biodiesel from Algae
has a focus on biodiesel production from algae while also discussing
alternative energy in general. Algae present an exciting possibility as a
feedstock for biodiesel, and when you realise that oil was originally
formed from algae - among others - you think "Hey! Why not oil
again from algae!"
To facilitate exploration of oil production from algae as well as exploration
of other alternative energy avenues, Oilgae provides web links, directory,
and related resources for algae-based biofuels / biodiesel along with inputs
on new inventions, discoveries & breakthroughs in other alternative
energy domains such as solar, wind, nuclear, hydro, geothermal, hydrogen
& fuel cells, gravitational, geothemal, human-powered, ocean & wave /
tidal energy.
