Never Mind Recycled Paper, Here’s a Recycled Printer (at least part of it)

Here’s a step in a different direction. If you’re the type who likes to make a difference by using recycled paper for your printing jobs in order to offset a tiny portion of the deforestation you could take a little step further and help out with recycled printer parts. Now I’m not encouraging you to go out and buy a new printer if you already have a perfectly good one. That would be defeating the purpose. But if you are in the market for a printer because you need one, then you may consider this neat gadget.

Wireless Fridge: Refridgeration without Electricity

For hundreds of years a similar type of cooling has been employed by desert dwellers around the world. The concept is explained by a simple law of thermodynamics. When moisture comes in contact with dry air it evaporates. You see, water has this amazing characteristic of having a very high retention of heat (it is used in cooling nuclear reactors after all).

This ancient technology has been used for cooling water for hundreds of years. Mohammed Bah Abba took this idea one step further. By placing one pot inside another and filling the gap in between the two pots with moist sand he was able to create a refrigeration system that requires nothing more than a little bit of moisture.

The moist sand filling the gap between the two pots draws heat away from the inner pot and dissipates the heat through the evaporation of the moisture. The inner pot is filled with perishable foods that would normally last for mere days, but with this system can last for weeks.
