What is Fetu ROTICULATE?

Markets & Tech Readiness

FeTu’s Unique Selling Points

Gas compressor (tests complete, proof of concept & commercial viability)

Test highlights: 7.2:1 PR @ 1,500rpm (6.2barg); over 75% indicated efficiency; oil-free; capable of generating 45kPa vacuum at only 50rpm. Unlike convention where one seems at the expense of the other, FeTu is both high-pressure and high-volume, and importantly is instantaneously effective from start-up.  During test it has described the attributes of an ideal compressor, with an unrivalled Polytropic index of 1.1. On the assumption of lossless porting and lossless sealing, FeTu can achieve 99.99% volumetric efficiency.  

Able to produce high pressures at standard motor speeds, FeTu offers direct coupling without associated losses from speed correction (gearbox / inverter).  Units are compact, inordinately light and low noise.  FeTu’s combined characteristics are highly desirable and not currently available in a single offering; the potential to run oil free and 90% isentropic efficiency offer a drastic step-change in a sector desperate for energy & net CO2 savings. 

The Innovate UK open call project was pronounced a success and over-delivery on IUK expectation was acknowledged. Despite the success of this ‘feasibility study', it was agreed that we have not yet explored or demonstrated anywhere near the true potential or limits of this device. 

Positive displacement pump (JV with an automotive tier 1 in place, proving as a cooling pump for EV’s)

Combined capability of high pressure, high volume and absolute metering from a single unit.  Positive displacement enables self-priming and high turn down ratios, bi-directional (mirrored) effectivity, low-noise, low TCO, light weight, simple and reliable.  Clean media pumps are prolific, the market is significant and growing, no existing technology offers FeTu’s combined yet highly desirable characteristics. 

Closed-loop thermodynamic cycle

Some 200 years ago Sadi Carnot described an ‘ideal’ engine as being both ‘closed loop’ & ‘thermodynamically reversible’, such has never been found and often perceived impossible.  An effective closed loop system is seen by many as the key to unlocking mass decarbonisation by the provision of 100% renewable energy from abundant natural heat sources (solar & geothermal).  FeTu exhibits the characteristics of an ‘ideal’ engine.
