Philips recently announced its next-generation A-19 bulb with a new design that contrasts sharply with the old yellow EnduraLED or the fluorescent L-Prize bulb. The 60-watt replacement has a white appearance and uses 11 watts while putting out 830 lumens. It will be available in both Soft White or Daylight color temperatures when released.
Concrete is everywhere in construction, so I like to note what’s happening to make concrete “greener.“ CarbonCure Technologies, Inc. licenses technology in North America to make, for example, carbon-absorbed concrete blocks and other precast products. Basically, CO2 is injected during curing — making limestone — with the end result being a stronger, greener masonry and other precast products.
Here’s an update to an old article about a tree-shaped charger powered by solar energy. Vivien Muller’s Electree+ is on Kickstarter seeking to raise $200,000 to mass-produce these little home/office gadgets here in the USA. The new prototype will be made with an 14,000 mAh internal battery, 27 amorphous silicon solar cells (each about 3.7 inches), and an easy-to-assemble tree structure that can be customized. In case you’re interested, the early bird gets in at the ground level for ~$199.00.
