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.
Designed by Eun Ah Kim, Jinhyuk Rho & Maria Rho, “Off” is a door handle with connections to your mains like gas supply and electricity. Simply switch off both or either one of the services by rotating the dial and flip it back to activate it all. With “Off” we don’t need to keep locking and opening the door to check before we leave. Sounds great, just wonder, where the handler should be installed? And how we make sure only the family members have the rights to turn things off. 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]
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]
