This project is a solar powered Arduino based weather station and digital thermostat. Device is able to display temperature, humidity, barometric pressure and time/date. The sensor used is a SHT21 Temperature Humidity sensor. It is also equipped with a RGB led to display how comfortable the conditions are.

This project is used for charging sealed lead-acid batteries with a solar panel in small and portable applications. The charger will stop charging once a pre-set voltage (temperature compensated) has been reached, and resume charging when the voltage has dropped off. The load is disconnected when the battery voltage drops below 11V and reconnected when it gets back to 12.5V.

MIT chemical engineers have found a way to concentrate solar energy 100 times more than a regular photovoltaic cell. Such nanotubes could form antennas that capture and focus light energy, potentially allowing much smaller and more powerful solar arrays. [via]

MIT scientists have created a novel set of self-assembling molecules that can turn sunlight into electricity; the molecules can be repeatedly broken down and then reassembled quickly, just by adding or removing an additional solution.
In an attempt to imitate the process of photosynthesis, Michael Strano, the Charles and Hilda Roddey Associate Professor of Chemical Engineering, and his team, supported by grants from the MIT Energy Initiative, the Eni Solar Frontiers Center at MIT and the Department of Energy, produced synthetic molecules called phospholipids that form disks; these disks provide structural support for other molecules that actually respond to light, in structures called reaction centers, which release electrons when struck by particles of light.
