Infinity Supercritical Introduces Extraction Machine Test Datalogging Software

Infinity Supercritical has available (as a free download) a database that allows supercritical CO2 extraction machine operators to log run parameters and extraction results data. This data is crucial for developing new recipes and duplicating successful extraction runs. The database is run off of Filemaker software, and is a customizable solution, which allows entry of written data, images, sounds, and video. The solution will run with Windows/MAC and on iOS devices (iPhone and iPad) using Filemaker Go (free app). To download the free solution, please visit the Infinity Supercritical website.

New Power Generation Technology – Supercritical CO2 Turbine

Developing Power Generation Technology For Low Grade Waste Heat Above 31 C or 89 F


Utilizing low grade waste heat with supercritical CO2 is a Pandora’s Box for developers, mainly because of the high pressures involved. High pressure means expensive engineering and components. The best methodology is to develop smaller working CO2 turbine prototypes, and learn lessons on a small scale, with less costly results. Infinity has developed a platform to do this prototyping, using a modular cart, high pressure components, and a turbine that fits in a off-the-shelf high pressure filter housing.



Traditional Versus Fast Track Development

Traditional steam turbine development was slow and expensive. Conventional turbine development today may involve computational flow, CAD/CAM, and other tools which reduce development time, however there is still a trial-and-error testing period. Our methodology is to use 3D printing to decrease the testing period by first doing a plastic print to test on air and parts fitting, then do a metal 3D print, or more conventional vertical milling or waterjet machining for the turbine rotor, stator, and housing parts.


3D Turbine Generator Development

Using a 3D printer can greatly reduce the time to machine and test turbine designs. There are limitations with designs over 3 inches for metal 3D prints however. We’ve found that our prints using a ExOne metal additive system resultings in poor tolerance, from the shrinking of the metal during the sintering phase (heat curing oven). With a six inch and above rotor, we have found that additional post processing needs to be included for balancing the rotor, or finish.


Solid State Turbine

Retrospective of steam, rankine, organic, and supercritical cycles, the Holy Grail of prime movers would be a static turbine, with no moving parts. The cost and maintenance reduction, would then move the price point to such a level which would make power more affordable on any scale. To that end, Infinity is developing a method to generate electrostatic electricity, from the expansion of CO2 (which goes supercritical at 31 C or 89 F). This proess would reduce the footprint and costs by 100 times.


What Does the Future Hold ?

Converting low grade waste heat to power allows for point-of-use power generation, and access to solar thermal, geothermal, industrial waste heat, and computer server waste heat. The ability to utilize the waste heat in a solid-state turbine, with no moving parts will allow cost-effective power generation at any scale.

Infinity Turbine Introduces CO2 Turbine Generator That Fits In A Standard Filter Assembly

Infinity Turbine has developed a micro-sized CO2 Turbine Generator which fits inside a standard high pressure 1.5 liter filter assembly. The compact turbine generator can be used to utilized waste heat to energy, such has solar thermal, industrial waste heat, computer server waste heat, and other sources of heat at or above 30C (89F).

What is unique about this concept is that the waste heat can be used to generate power at the point of use. Now server farms (Amazon, Google, and GoDaddy) can use their low-grade (140F) waste heat to generate power. Green power (even in small amounts) on a small distributed grid, is better than powering a chiller to provide all the cooling of waste heat sources.
