Designer working at the intersection of strategy, systems, and sustainability

ABOUT














 






 


















Solair
Solair is a solar and ambient light powered personal fan designed for a hotter, more uncertain climate future. Grounded in Solar Punk philosophy, it asks: what would sustainable personal cooling look like?

SOLARPUNK

Solarpunk:
a social, literary, and artistic movement that imagines technology, nature, and humanity in harmony. Solarpunk is the design philosophy for Solair’s core values



Why Solarpunk Values are relevant today:  








Why many people don’t adapt Solar Energy:













So, what would sustainable personal cooling look like?



















Sustainable cooling products exist, but most ask users to spend more, sacrifice convenience, or commit to infrastructure they don't own


Solar adoption fails not because of performance, but because of perceived inconvenience and behavioral friction









Key Insights:


1. People increasingly value energy independence, especially as climate and policy become less stable


2. Sustainable products fail when they demand behavioral sacrifice 
= convenience is non-negotiable


3. Solar and cooling products are perceived as seasonal, which limits how much people are willing to invest in them

KEY INSIGHTS



BENCHMARK VS SOLAIR




   




97% Decrease in CO2e/5 years of use with Solair!


















The stakeholders who benefit from Solair’s design start from:


communities who are not mining for petrolium for plastic

to the end buyer but also to

the larger environment and ecosystem


Making sustainability feel inevitable rather than imposed was the hardest design constraint. If I were to continue this project, I'd prototype the Powerfoyle integration to test whether the energy output holds under real indoor conditions.

Solair  

Solair is a personal fan powered entirely by Powerfoyle cells, usable both indoors under ambient light and outdoors in direct sun. It requires no charging cable and no dedicated solar panel; it works wherever you are
