VerXisWind

VerxisWind exists to unlock the untapped kinetic energy that roars out of rail-tunnel portals every day and to turn it into verifiable financial and carbon value for infrastructure owners and investors.

Our mission

To equip engineers, financiers, and researchers with the definitive techno-economic toolset for piston-wind vertical-axis turbines driving smarter capital allocation, accelerating decarbonisation of the rail sector, and proving that no renewable resource is too unconventional to be bankable.

Why VerXis TEA Toolkit?

Fast first-order screening fills the gap

VerXis turns minimal inputs, basic tunnel geometry and timetable statistics, into bank-level KPIs in minutes, flagging only the promising sites for deeper engineering.

Design size is not one-size-fits-all: The toolkit ships with a library of rotor families and lets engineers scale diameter and height, ensuring each portal gets an economically optimised cassette rather than a generic “standard” unit.

Underlying formulations & User's guide

Have total control over the principals

Consistency & traceability: hard-coded physics + central cost library ensure every scenario is comparable.

Tangible results format

Access to a validated platform backed by research literature

Rapid “what-if” engine: change rotor Ø, train frequency, or price tariff and instantly see IRR, pay-back and abatement cost.
Bankability first: hit analytical rigour while keeping code readable for start-up engineers.
Open & extensible: new rotor designs, alternative discount-rate policies, or regional carbon factors can be added in < 5 lines.
Risk quantification: built-in tornado charts, Monte-Carlo, and learning-curve modules surface the sensitivities.
Visual storytelling: every run exports publication-quality PNGs for investor deck.
