Calculation confidence
Review the original model and reduce the risk of presenting overly optimistic results.
The challengeMore than a spreadsheet
The starting point
A concept that needed credible, physical proof
The initial calculation sheet was useful for exploring the idea, but it needed greater functionality and detail. GiroStor also needed a demonstrator that could make the technology easier to understand during investor conversations.
A flywheel demonstrator introduces a clear physical risk: a rotating heavy mass. The job was not simply to make something move. The calculation model, mechanical system, controls and user interface had to tell one coherent technical story, with safety considered from the outset.
Physical integration
Bring mechanics, electronics, controls and the interface together in one working demonstrator.
Safety by design
Manage the rotating mass through practical design decisions and a defined control layer.
Our approachDefine · Prove · Build
Connected development
Resolve the important questions early
We treated the spreadsheet and the demonstrator as complementary parts of the same project: one helped explore and explain the expected behaviour; the other made the concept tangible.
Define
We reviewed the existing Excel model, checked the underlying assumptions and identified where more detail and functionality were needed.
Prove
We developed the calculation tool and selected a benchtop approach that allowed the rotational speed to be reduced.
Build
We integrated the mechanical assembly, electronics, controls, professional safety relays and touchscreen live-data display.
The result
Useful evidence and something real to show
GiroStor received a more detailed, functional Excel calculation model and a working benchtop flywheel demonstrator for investor meetings.
The calculation work provided a stronger basis for discussing the concept. The physical build gave the team a tangible way to explain how the system operated, supported by live output and graphs rather than a presentation alone.

Client testimonial
“Twocan Ltd has been an outstanding partner for GiroStor. They initially supported us by developing sophisticated Excel models that became an important part of our investor presentations, delivering work of exceptional quality and helping us communicate our technology with confidence.
Following that success, we engaged them to design and build a desktop-scale flywheel demonstrator. Once again, they exceeded our expectations. Their combination of technical expertise, creativity, and practical engineering ensured the project was delivered to a very high standard.
What sets Twocan Ltd apart is their proactive approach, clear communication, and genuine commitment to finding the best solution. They are a pleasure to work with, consistently delivering beyond what is expected.
I would recommend Twocan Ltd without reservation to any organisation looking for an innovative, capable, and dependable engineering partner. Without Twocan we wouldn't be here today”
