Around The Home Review

Review: aerelight OLED lamp

While OLED technology is increasingly being applied to things like electronic gadget displays and TVs, it can also serve as an efficient and aesthetically-pleasing form of lighting. A number of companies have capitalized on this fact by marketing OLED lamps, although most of them are quite expensive – prices can range from around US$500 up into the thousands. Canada's OTI Lumionics, however, has developed its own cost-effective OLED lighting system, and incorporated it into the $239 aerelight. I recently got to try one out for myself. Read More

Discarded laptop batteries could be used to power homes

A study by IBM researchers has revealed that many discarded laptop batteries have the potential to provide enough power to keep the lights running in homes in poorer countries around the world. The India-based team conducted a small study to test the viability of the idea, with work now focused on streamlining a prototype system. Read More

The problem with those codes, along with things like RFID and NFC tags, is that they detract from the appearance of the item. Fujitsu Laboratories, however, has developed an alternative system. It uses the light shining on the object to convey data. Read More

Cheap, ultra low-power light source runs on just 0.1 Watts

Researchers at Tohoku University in Japan have developed a new low-cost flat panel light source that could pioneer a new generation of brighter, cheaper and greener lighting devices to rival LEDs. The device uses arrays of highly conductive carbon nanotubes to deliver evenly-distributed illumination with high efficiency and a power consumption as low as 0.1 Watts – about 100 times lower than that of light-emitting diodes.

Footballers' pounding feet power community soccer pitch lights

Just over three years ago, a UK company looking to harvest the kinetic energy of pedestrians received its very installation order. Since then we've seen Pavegen's tiles turn to the crowd for school installs and being laid at the Paris Marathon. Now the firm has partnered with Shell for its biggest undertaking so far – to give a run-down community soccer field in a Rio de Janeiro favela an off-grid power supply which benefits the whole community.Read More
