In Canada, Evercloak is spinning out nanotechnology research from the University of Waterloo to develop innovative ways to manufacture membranes that improve the efficiency of cooling units. Co-founder Evelyn Allen and her team are finessing the process of manufacturing graphene-based membranes that filter water from the air before it is cooled. These membranes — each one thinner than a strand of hair — are able to block air flow but let water vapour to move through. This means an air conditioner would require less energy and building owners could use a smaller unit to cool indoor spaces. Energy efficiency gains are significant, Allen says, and can see a reduction up to 78 per cent in energy expended in hot, humid regions. The venture is currently working with traditional AC manufacturers to commercialize this technology.
