Treehugger points us to an intriguing concept design for a solar powered LED lamp that sticks to windows. Rui Palma’s Lucet lamp can also be charged up and attached to other surfaces as well. The design of the light also allows for users to combine multiple units in different configurations.

Though it looks like a solid idea at first glance, Treehugger recommends a few improvements:

First, it uses AAA batteries to store the solar power. This is bad in that we’d like to get off of these types of batteries altogether. Plus, it would take quite a long time in the sun (asa in several days) to charge AAA batteries to full. But, this isn’t all bad because it also means that the lamps could double as a battery charger for AAAs used in other devices. And because the LED bulbs use such little energy, it wouldn’t take more than a full day of sun to run the lamp for several hours in the evening.
