AlgaeBulb: a Green Power Light Bulb by Gyula Bodonyi

Designed by Gyula Bodonyi, the AlgaeBulb is an exploration into the use of the organisms on a micro-scale in single LED lightbulb that harnesses the green-power of algae. It is LED bulb with extra air pump at the head part. This pump compress the air into the algae tank covered with a hidrophobic material, that keeps the fluid content in the tank and let the air flow free. While algae flourishes, it gives off oxygen, which in turn powers the tiny LED inside.

When the AlgaeBulb is not illuminated, it appears to be a dark green; a result of the colony of micro-algae living within. When illuminated, it gives off a slightly green tinge on the interior, making for a green bulb that is literally “green.” Until now. This is just a concept design.

Since you definitely don’t want a prankster or and intruder turn off your utilities, includes your security system, from outside. It’s better work with key or password![source]

Innovative Wind Powered Watch by Julien Moise

This interactive watch by Julien Moise uses the wearer’s own renewable wind energy to power it’s icy blue display. To read the time the user simply blows on the propeller mechanism to generate just enough electricity to activate a short visual sequence. It looks like a nice design but definitely need more technical thinking, such as the damage caused by dust, rain, sleeves? And how to keep the hour on time if the blowing is just for display. Does it still require some kind of battery to make sure the watch is on time? [source]
