Lately, I've been posting on more eco-friendly technologies (such as the car that runs on water or the gadget that charges your cellphone while you dance) because I've been increasingly concerned about the serious consequences that may occur if Humanity doesn't find alternative sources of energy to end our dependency on fossil fuels.
And to continue in that wave of eco-friendly technologies, here's a list of some interesting gadgets/ideas to turn our technology consumption a bit more "green":
- Solar Cells under Multi-touch displays - This is an idea based on the patent that Apple recently registered that stated their intention of creating a layer below the iPhone's display made out of solar cells. The idea is really insteresting as it allows you to leave your gadget on the sun to charge itself, but I still have doubts if it's actually a good idea to leave the gadget exposed to intensive heat :-)
- Solar cell backpack - This one is obvious. This backpack receives sunlight and turns it into energy used to charge your gadgets inside, such as a laptop, cellphone or iPod.
- USB-rechargeable battery - Forget about special chargers that you have to use to charge your batteries. This battery charges itself once connected to a computer's USB port.
- Kinetic-based batteries - In the same line as the dance charger, this battery charges itself with the movement that a person produces while walking, which means that it doesn't need to be connected to an energy source directly to be then used in some gadget :-)
