What do you get when you bring together a pizza oven, some nail polish and inkjet printers? Solar cells. You and I may be scratching our heads, but the woman behind the process known as iJet, Nicole Kuepper, won two Australian Museum Eureka Prizes — Australia's top science awards. The real beauty of Ms. Kuepper's accomplishment — beyond the simple recipe — is that a low-heat process like this is both cost effective and easily replicated, meaning that developing countries could get everything they need for cheap, renewable energy using junk you could find at a garage sale.
How does it work? We don't know, and probably won't be able to find out as it has just been recently patented, but it feels like a better world already.
CORRECTION: It's MacGyver!
