Access to solar power is increasing, albeit slowly and at a steep price. A Florida company called SkyShades is selling shade umbrellas equipped with flexible solar panels that slip into the canopies. There’re being sold to coffee shops as well as leisure resorts that want more battery-charging capability poolside. “My friends who go to places like Starbucks have said there has been insufficient access to outlets,” Joe McKenna, executive vice president of SkyShades said in a recent interview with me. They’re pricey - at $10,000. But the regular price for these canopies is $5,200. “They seem expensive. However for SkyShades to build a PVC structure it would cost $75-$80 per sq ft and these work out to about $31 per sq ft.” adds McKenna. Another new consumer item is a handbag with integrated solar panels. Price: $472. This is pretty much in the realm of the Tesla electric cars that sell for more than $100,000. You can buy these products, but for a while real solar-powered stuff is pretty much a toy for the eco-rich. Check my feature in the April issue of Design News for the amazing plastics technology that provides power for the flexible solar panels.
Plastic bags can become useful as either raw materials for plastics or feedstock for fuel. It's when they're not recycled that they become a major problem. That's what California's bag ban will prevent.
NASA's JPL and Caltech have achieved the mind-boggling feat of 3D printing multiple metals in a single end-part, grading from one alloy to another. They've also developed a method for combining metals with carbon fiber composites in end-production parts.
