A team at IBM recently developed what they call a High Concentration Photo Voltaic Thermal (HCPVT) system that is capable of concentrating the power of 2,000 suns. “Each 1cmX1cm chip can convert 200-250 watts, on average, over a typical eight-hour day in a sunny region. In the HCPVT system, instead of heating a building, the 90 degree Celsius water will pass through a porous membrane distillation system where it is then vaporized and desalinated. Such a system could provide 30-40 liters of drinkable water per square meter of receiver area per day, while still generating electricity with a more than 25 percent yield or two kilowatts hours per day. A large installation would provide enough water for a small town.”
We have seen huge advancements in 3D printing. We’ve even seen oversized wrenches printed that measure 1.2 meters in length. Now, we can print an entire 2,500 sqft house in 20 hours.
"In manufacturing we use a process called CAD/CAM (computer-aided design / computer-aided manufacturing). 3D models are designed on a computer and then manufactured using computer controlled Machines or 3D printers."
3D printing may have an image problem. It's sometimes seen as a hobbyist pursuit -- a fun way to build knickknacks from your living room desktop -- but a growing number of companies are giving serious thought to the technology to help get new ideas...
