The Phaeton, developed by Fraser Symington and Lorin Symington of ASTRA is a powerful and innovative approach to solar cooking. It consists of an array of mirrors on a straight steel frame focusing to a secondary reflector which reflects the light upwards to a convenient working height of 75cm or 30″. With 35 square feet or 3.2 square meters of collection area the Phaeton array achieves a 5min/1L boil. A pot with 8L of water will boil in 35 minutes with 1000w/m2 of incoming solar radiation.

The Phaeton is one of the most cost effective solar cooking solutions available today. In Puerto Penasco in Mexico, ASTRA built a Phaeton for $364US. At any sort of commercial construction scale the cost will quickly drop to below $300US. At Mexican skilled trade rates of $40US per day for a skilled tradesman and his assistant, labour costs would be $160US per array at the artisinal scale, falling to approximately $100US in a dedicated fabrication facility. This amounts to a $400US 2kw solar cooker able to serve a couple of households or small business, or as a community solar cooker with a payback time of approximately one year or as little as two months in extreme conditions. The Phaeton is among the most versatile of solar cookers due to the high temperatures it achieves, the Phaeton can bake, boil, fry, roast, dry, or distill.

What’s a Twike? It’s half-bike, half-electric car

              There are 1,000 of these hybrid muscle/battery power vehicles on the road, mostly in Europe. Only a few are in the U.S., but does 3 cents a mile sound good? It’s a made-in-Germany combination of an electric bicycle with an EV. It may be that we’ll see more of these hybrids popping up as our cities get less friendly to gas guzzlers. Driving 60 miles is going to cost you $2, the company says. The Twike you’re looking at is one of the few in...

Can Cloud Power Provide Clean Water and Electricity for the World?

                  Wind, water, solar are common sources of renewable energy, but what about the clouds? Can cloud power provide our clean energy and water needs? A Russian scientist is aiming to do just that with the Air HES (Hydro Electric Station) — a tethered blimp that captures water from the clouds with a mesh that hangs vertically in the air and sends water to a hydropower plant on the ground via conduit attachments. A turbo generator then...

The house made from 4,000 video cassettes and two tonnes of jeans

              The Brighton Waste House is Britain’s first house made almost entirely from rubbish, including chalk, coffee cups and lights en route to Bangladesh Toothbrushes, along with video cassettes are being tested for their insulation qualities. Chalk is also being tested after a lorry-load of it heading for landfill was rescued. The construction industry currently discards 20% of everything it uses, meaning that for every five houses built enough...
