*This has just got to be the aw3som3st fab in the world. Almost sort of actually functions in the real world, apparently.

"Amongst the wonderful collection of work currently on show at the Royal College of Art, (((world nexus of "critical design"))) in the corner on the first floor sits an installation/object by Markus Kayser called Solar Sinter. An MA Design Products student project, Solar Sinter is probably one of the most inspiring projects this year, aiming 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.
"In a world increasingly concerned with questions of energy production and raw material shortages, this project explores the potential of desert manufacturing, where energy and material occur in abundance. In this experiment sunlight and sand are used as raw energy and material to produce glass objects using a 3D printing process, that combines natural energy and material with high-tech production technology.
"In August 2010 Markus Kayser took his first solar machine – the Sun-Cutter (see video below) (((really, you should have a look))) – to the Egyptian desert in a suitcase. This was a solar-powered, semi-automated low-tech laser cutter, that used the power of the sun to drive it and directly harnessed its rays through a glass ball lens to ‘laser’ cut 2D components using a cam-guided system...."
