Introducing the SST   (Solid State Turbine) Producing Electricity Using CO2 With No Moving Parts

 

TriboElectric Effect: Nikola Tesla worked with static electricity and wireless transmission in 1899 from the top of Pikes Peak to his lab in Colorado Springs, Colorado. Fast forward to 2016. Infinity was working with Supercritical CO2 systems, when they discovered an interesting effect - static electricity when CO2 passed over certain materials. That discovery became a commercial product called the TriboTube, which is a electrostatic precipitator that assists in removing oil and particulates from CO2 gas. Now Infinity is developing a solid state power generator, utilizing CO2.

 

Carbon Dioxide Unique Properties: CO2 is unique in that it goes supercritical (liquid to gas phase) at 31 C (88 F). Typical steam plants require 212 F and higher to generate steam to spin a turbine and generator to make power. Sandia Labs has experimented with CO2 and has identified it as the future working fluid of power plants, from it’s unique power density that results in smaller footprint power generation equipment. Using the Brayton Cycle, the CO2 gas is heated, and expanded over a turbine to spin a generator to make power. The cycle is like a jet engine, in that the working fluid stays as a gas. A standard fossil fuel power plant uses Rankine Cycle to make power - that is taking water, adding heat to make steam, then expanding that over a turbine to spin a generator to make power. The steam is then condensed back to water, and the process is repeated. The issues with these methods of generating power are that they use inherently expensive equipment, and require huge installations to get economies of scale (i.e. affordable power). What is needed is a scaleable solid state power generator, which is able to use the entire spectrum of heat range from low to high heat.

 

Infinity Turbine - TriboGen: Infinity has developed a process to use the power dense CO2 in a closed-loop Supercritical Rankine Cycle, to produce DC electricity. Because CO2 can do a phase change from liquid to gas at 31 C, it opens up huge low quality heat sources that can now generate power. It is optimal for Supercritical Rankine Cycle applications. Our system makes electricity from heated liquid 31 C and higher, which includes solar, hot geothermal, engine waste heat from stack and oil cooling, data centers, cloud server cooling, compressor, and industrial waste heat. TENG (Tribo Electric Generation). The process can also be used to power ESP (Electro Static Propulsion).

 

Power That’s Scalable: What’s unique about the Triboelectric effect that Infinity is developing, is that it can be used in a small nano or micro-channel application to generate IC chip power, or in a larger assembly to power a smartphone, house, or numbered up to distributed power generation. What is significant about this technology is the ability to access an utilize low grade heat, as low as 31 C.

Infinity Turbine - TriboGen - TriboEffect in Action

This short movie shows the Trioelectric effect as CO2 is expanded over a hybrid material into the air. The voltmeter shows that electricity is being generated. Infinity Turbine is building a power generation system that recycles (closed-loop) the CO2 using low grade waste heat. The heat takes the CO2 supercritical (increase in pressure) and then it’s expanded over a material which produces a DC charge. That charge is harvested for use. The CO2 gas is then cooled to a liquid and recirculated to a heat exchanger that takes the low grade heat, and transfers that heat into the CO2 to phase change it from liquid to gas.

Example of a Organic Ranking Cycle System, which has a turbine that spins a DC generator. Liquid waste heat is supplied to a heat exchanger, which phase changes a liquid refrigerant to a pressurized gas. A refrigerant is used to take advantage of low grade heat down to 80 C.

Example of a Infinity Turbine Axial Turbine DC Generator. This type turbine takes pressure flow to move a rotor, connected to a generator.

Here is a snapshot of the technology: 

 

- can use heat as low as 30 C (CO2 goes supercritical at 30C)

- requires the use of a compressor or pump (this is a supercritical

Rankine cycle)

- the expanding CO2 can also be used for a rotating turbomachinery (to

further expand on power produced), but this requires a more complex

arrangement, which extends the solid-state turbine technology in

original concept. Under this complex arrangement, complex bearings

will need to be used, and mechanism to drive generator developed (if

externally driven generator), including, but not limited to high

pressure shaft seals, which are not required in the solid-state

turbine portion.

- the expanding CO2 cooling may be used for other technology (chiller, etc)

- the expanding CO2 can be used in a jet-pump (possible solid-state

feedpump) but this has to be developed and tested

- the expanding CO2 can be used for electrostatic precipitation

- technology can be made on small scale and then scaled up to any size

- technology can be used at point-of-use to utilize waste heat where

it is produced

- the static produced can be possibly used in a boiler or heat

recovery unit to significantly enhance the evaporation of liquid to

pressurized vapor.

- a rotary cavitation disc can be installed as a pressure reduction

device to vaporize liquid to pressurized vapor (act as a compressor)

- technology can be used to excite coils wirelessly

- technology can be used with electronic switching to make what is

effectively a solid state electrical generator

- technology can be used to charge a coil (rail gun, laser, etc.)

- technology can be used to make a magnetic field

- technology can be used to produce a corona discharge, to UV purify

water, or light welding, cutting, and engraving
