Question 1

What makes HeliosReflect different from existing solar concentrators?

Accepted Answer

Current systems convert light into heat or electricity. The HeliosReflect proposal is an integral architecture: one infrastructure producing electricity, light transport through optical fibres, industrial heat and photochemical processes. The core piece (HR-DOC) is under validation; the multifunctional infrastructure vision is the conceptual difference.

Question 2

Is it not the same as a Dish-Stirling or a Cassegrain system?

Accepted Answer

They share classical optical principles (the focal property of the parabola). The difference lies in the compound mapping of two confocal paraboloids and in the goal of delivering a concentrated parallel beam to a single receiver, not a point image. It is a technical proposal that must be validated experimentally.

Question 3

Why is it not built yet?

Accepted Answer

Because of rigour. Before building, the hypothesis must be mathematically proven sound and free of physical law violations. That theoretical validation is closed; the experimental one is designed and pending funding. Building before validating would be irresponsible.

Question 4

What is demonstrated today and what is not?

Accepted Answer

Demonstrated: the focal property of the parabola, conservation of energy, conservation of étendue and the thermodynamic concentration limit, plus the analytical and numerical validation of HR-DOC (including a 200,000-ray Monte Carlo simulation). Not demonstrated: behaviour with real mirrors, manufacturing tolerances and performance at scale; those require experimentation.

Question 5

Does it not violate the second law of thermodynamics?

Accepted Answer

No. Concentration without losses is bounded by étendue conservation: any real concentrator operates within that limit. Simulations verify the design respects the thermodynamic limit. The goal is not to violate physics, but to get closer to the theoretical limit than current designs.

Question 6

How much CO₂ will a plant capture?

Accepted Answer

No published CO₂ capture figure would be supported by evidence today. That value depends on the specific photochemistry, still under research. We publish hypotheses, not results, until experimental validation exists.

Question 7

What are the main risks of the project?

Accepted Answer

Three: that experimental validation refutes the central hypothesis (scientific risk), that real performance at scale falls below the theoretical one (technical risk), and that economic viability cannot compete with established solar technologies (market risk). All three are managed with a progressive validation roadmap.

Question 8

What exactly does "not demonstrated" mean?

Accepted Answer

In this project, "not demonstrated" is used with precision: it means that no experimental evidence exists yet. It does not mean "false", nor "probably false". The distinction between demonstrated, partially demonstrated and hypothesis is the backbone of the Transparency Center.

Question 9

Who is behind the project?

Accepted Answer

The project is driven by Oriol Garcia Salas, with the conviction that it is built through collaboration. The collaboration page describes the needed profiles: mathematicians, physicists, engineers, research centres, companies and investors. No central hypothesis depends on a single person.

Question 10

How much does validating the project cost?

Accepted Answer

The exact budget is shared under agreement with collaborators. The strategy is phased funding: validation first (grants and universities), then prototypes (seed rounds and Deep Tech), then industrialisation.

Question 11

Can I access the technical documentation?

Accepted Answer

Public information covers the vision and validation status. Advanced technical documentation (complete geometries, algorithms, critical parameters) is shared under confidentiality agreements with active collaborators and investors, to protect the value of the knowledge.

Question 12

How can I collaborate?

Accepted Answer

The collaboration page describes the profiles: universities, research centres, companies, engineers, patrons and investors. The direct route is the contact form. Access to advanced documentation is prioritised for those actively participating.
