Markus Kayser thinks outside the box when it comes to sustainable energy. He harnesses the potential of that celestial ball of fire to create glass objects, realising the possibility that this type of energy could be a large part of the future. But aside from the scientific business, it’s amazing to see art made this way!

Conceptualised as part of his MA in Design Products, at the Royal College of Art, Kayser reveals on his website that “solar-sintering aims to raise questions about the future of manufacturing and triggers dreams of the full utilisation of the production potential of the world’s most efficient energy resource—the sun.” Solar-sintering involves magnifying the sun’s rays to create extreme temperatures, melting raw materials, such as sand, to create glass objects, using a 3D printing press.

Seeing him drag his mad contraption through the sand, he looks a little odd, dressed in suave, white desert gear. But when we go into micro mode and see the machine start up, his true artistic genius is revealed. The process of heating the sand then adding fresh sand seems painstaking but the end result is oddly breathtaking. As he brushes away the excess, the final product is revealed. A piece of art sculptured using sand, sun, and genius!
