Amorphous Wire Pressure Sensor

Closed containers may gain or lose pressure due to a variety of reasons, and opening these containers may be dangerous. The Amorphous Wire Pressure Sensor is a passive, wireless sensor for determining the internal pressure of a sealed container without the need for penetrations. The sensor can be embedded inside a container and its data read through the wall by an external detector.

Passive In Situ Gas and Chemical Sensor

In many sealed systems, the spontaneous generation of chemicals and gases can adversely affect the contents of a sealed system. The container or system is closed, and sampling is impossible. A passive method for detecting the presence of specific chemicals in the system is critical and addresses a key question: How do you ascertain the integrity of the contents in a sealed container without opening it? This invention allows a sealed system to be monitored for the infiltration or generation... read more

High Temperature Downhole Motor

Drilling costs amount to over half of the total cost of geothermal energy production. To address the high cost of well construction, Sandia engineers are developing a high temperature downhole motor that provides a high-power downhole rotation solution for directional drilling. Commercially available downhole motors, such as Positive Displacement Motors (PDM), rely on elastomeric material, limiting operations to approximately 350°F or less, making them unreliable for extended use in... read more

Method and Apparatus for High-Efficiency Direct Contact Condensation

Geothermal resources, the steam and water that lie below the earth’s surface, have the potential to supply vast amounts of clean energy. But continuing to produce geothermal power efficiently and economically requires innovative adjustments to the technology used to process it.

In the late 1990s, the pressure of geothermal steam at The Geysers (A geothermal plant in northern California) was falling, reducing the output of its power plants. NREL partnered with Pacific Gas and... read more

TOUGH +: Modeling Fluid and Heat Flow in Porous and Fractured Ground
TOUGH+ is a general-purpose numerical simulation program for modeling multiphase fluid and heat flow through porous and fractured media. It is the successor to the TOUGH2 suite of codes developed at the Lawrence Berkeley National Laboratory (LBNL). Various modules can be linked to the core of TOUGH+ to describe different fluids and their compositions, or to simulate more complex, coupled processes.

Novel Tube-in-Tube System Simplifies Subsurface Fluid Sampling
Barry Freifeld of Berkeley Lab has developed a device that simplifies subsurface fluid sampling. The technology’s tube-within-a-tube construction is a substantial improvement to the U-tube sampling system widely used for borehole sampling today. Using only one line, instead of two, the tube-in-tube system enables the sampling device to get lowered easily through a pressure control device (such as a grease head or pack-off) for discrete level sampling of live oil and gas wells.... read more

Substantially Parallel Flux Uncluttered Rotor Machines (U-Machine)
A general concern based on the supply and demand trend of the permanent magnet (PM) raw materials suggests the need for elimination of these materials from electric motors (and generators) to control future costs. This invention discloses a new motor topology that eliminates the PM. Other innovations include brushless adjustable field excitation for high starting torque, field weakening, and power factor improvement and novel locks for higher peak speed. This novel machine shows promising... read more
