Vertical Farming: Valcent, a company based in El Paso, Texas, is pioneering a space efficient hydroponic-farming system that grows plants in rotating rows, which expands food supplies without using more land. The rotation gives the plants the precise amount of light and nutrients they need, while the vertical stacking enables the use of far less water than conventional farming. The company claims it will use 95 percent less water than conventional agriculture, increase crop yields 20-fold for the same amount of land, and eliminate pesticide and herbicide use.
Green inventions for Water: This invention enables the extraction of water from the atmosphere. The Solar Powered Water Purifier eliminates the need to boil water using wood or coal. There are currently 1.2 billion people in the world living without clean drinking water.
Reusable Fruit and Vegtable Bags: As revealed in the sneak peek of G Magazine’s list of the year’s 10 most innovative eco-products, there have been a few interesting green inventions from Australia in 2009 including Greensacks, a finalist in the 2009 news.com.au Green Awards. Greensacks are reusable, lightweight mesh bags designed to replace small, single-use plastic fruit and vegie bags. A reusable alternative to plastic bags will reduce the current Australian use of over 10 million plastic bags a day, which take between 15 and 1,000 years to break down.
