D4R Laptop Overview The iameco D4R laptop is the first truly environmentally-friendly laptop. We have focused both what the laptop is made from, and how it is made, in order to reduce energy consumption, encourage re-use and eliminate waste. The goals in developing the laptop were: achieve a decrease of at least 30% in greenhouse gas (GHG) emissionsat least 70% of overall re-use and recycling of waste anda reduction of at least 75% of fresh water utilisation. Working with partners in industry and academia including the Fraunhofer Institute in Berlin, the University of Limerick in Ireland, GAIA in the Basque Country and AUO Optronics in Taiwan we have achieved these goals through:
Welcome to The Sietch - Projects Build Your Own Solar Thermal Panel After our first attempt at a home built proof of concept solar thermal panel, we were a bit disappointed with the results.

My first mistake with the first one was purchasing everything new. With ample reusable resources at the local town dump I knew it could be done on the cheap.
Types of Water Filtration Systems Bacteria, parasites, fluoride, chlorine, emerging pollutants…just a few of the reasons why you may be considering a water filtration system.

A Practical Zeer Pot (evaporative cooler / non-electrical refrigerator) A zeer pot is an evaporative cooler used in rural Africa and the Middle East to keep vegetables fresh. They consist of two terra cotta pots, one nested inside the other, with the gap between them filled with wet sand. The sand serves as a thermal mass that helps keep the pot cold once it has cooled down, and acts as a wick to spread the moisture up the walls of the pot. When placed in a shaded, breezy location, the evaporation of water off the outer surface chills the pot.
Littoral zone The littoral zone is the part of a sea, lake or river that is close to the shore. In coastal environments the littoral zone extends from the high water mark, which is rarely inundated, to shoreline areas that are permanently submerged. It always includes this intertidal zone and is often used to mean the same as the intertidal zone. However, the meaning of "littoral zone" can extend well beyond the intertidal zone. There is no single definition.
