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.

This week Massachusetts-based Osram Sylvania announced a 100-watt replacement LED light bulb that uses only 20 watts of energy. In fact, the company claims it’s the first to market with such a replacement offering. Sylvania Ultra LED is an A21 bulb (larger than the A19 shape) with a rated life of up to 25,000 hours, a color temperature of 2700 Kelvin, and a CRI of 80. The LED bulb outputs 1600 lumens, according to LEDs Magazine, and is expected to sell for about $50 at Lowe’s.
