AETHERWHAT IFEVERY WINDOWCOULD GENERATE
CLEAN ENERGY?
Cities are surrounded
by glass.
But most of it is passive.
Curtain-wall façades already face the sun for the entire life of a building. Today that surface carries light, heat and view — but no generation.
The surface
already exists.
What if it could do more?
Transparent solar architecture.
Harvesting invisible light.
An ancient idea of the invisible.
Reimagined for a modern world.
Turning invisible light into visible impact.
Aether was a philosophical idea of an unseen medium of the upper sky. It is used here as brand metaphor — not as a claim about modern physics.
Light in.
Current out.
The view stays.

Frame + Electrical Connection
From waste to
functional material.
Can materials we throw away become part of the energy systems we build?
Proposed material pathway. Natural pigments are studied here as candidate luminophores; each source would require independent optical and stability validation.

Agricultural / Food Waste
Selected crop material is collected and sorted.
Conceptual process — a proposed prototype pathway, not a validated industrial line.

EXPLODED VIEW · HOVER A LAYER TO ISOLATE
The window doesn't absorb the sun.
It reimagines what it uses.
Only a selected fraction of incoming radiation interacts with the luminescent layer. The visible portion continues through the glass — which is why the window stays a window.
Selected ultraviolet radiation is absorbed by the luminescent material.
ZOOM · LUMINESCENT LAYER
The absorbed energy is re-emitted at longer wavelengths.
Internal reflection guides the emitted light through the panel.
TOTAL INTERNAL REFLECTION · CONTROLLED PATH
Light from across the panel is concentrated at its edges.
The centre of the panel is never covered. Generation is moved to the perimeter, where the guided emission arrives.
Edge-mounted photovoltaic cells convert the received light into DC electricity.
No current flows through the glass itself — conversion happens only at the perimeter cells.
ILLUSTRATIVE DESIGN-CASE MODEL
ESTIMATED OUTPUT
12.9W
E = 1000 W/m² × max(0, cos θ) × 1.00 m² × 0.015
Illustrative design-case model — a deterministic geometric calculation, not measured experimental performance. Clamped between 0 W and 15 W.
A prototype you can inspect.

Preliminary conceptual cost model
REFERENCE UNIT · 1.00 × 1.00 m · 6 MM CLEAR TOUGHENED GLASS
Preliminary conceptual cost model — not a manufacturing cost or a market price, and no claim of profitability. Actual cost would depend on material formulation, fabrication method, PV cell selection, manufacturing scale, testing and local sourcing.
Five goals, one surface.
AETHER is designed against the United Nations 2030 Agenda — a window that answers five of the seventeen Sustainable Development Goals at once.
Goal 7
Affordable and Clean Energy
Clean generation from a surface every building already has.
Goal 9
Industry, Innovation and Infrastructure
Glass becomes part of energy infrastructure, not just enclosure.
Goal 11
Sustainable Cities and Communities
Buildings contribute to the supply of the cities they sit in.
Goal 12
Responsible Consumption and Production
Agricultural waste re-enters the economy as a functional material.
Goal 13
Climate Action
Every generating window displaces conventional grid demand.
Contribution is framed qualitatively against the UN Sustainable Development Goals. No specific emissions, savings or generation figures are claimed at this stage.
Residential
Apartment glazing that also contributes.
One window.
Every additional architectural surface becomes another potential generation surface.
