Farmville, a New City Life?

This week, we are bringing you the latest urban agriculture related news mixed with lots of good-to-know information and unique projects that are happening across the United States. As efforts to reclaim our food system persist, innovators across the country have been working hard to bring farming back to the urban environment. From low-tech DIY solutions to traditional farming methods, there is a lot to learn and plenty to share. Feel free to share your thoughts and links to your favorite urban agriculture resources, and don't forget to tell us about the urban farming projects in your town! Mike Lieberman.

The vertical farming system allows leafy green vegetables to be grown all year round in urban environments in much smaller spaces, using much smaller amounts of energy and water while generating higher yields.

According to the VertiCrop site, using the system requires just 8 per cent of normal water consumption used to irrigate crops, can work in any climate, can grow more than 50 varieties of leafy green vegetables, and offers yields about 20 times higher than normal production of field crops. Valcent's vertical farming system was named in 2009 by Time magazine as one of the top 50 innovations of the year. Read more [...]

Geothermal Energy

You've never thought about the earth being like a boiled egg but think about it: If you cut the egg in half the yellow yoke is like the core of the earth and the white part would be the earth's mantle. The thin shell, discarded after the egg is boiled, is like the earth's crust. The geothermal energy, has been around for as long as the earth has existed. "Geo" means earth, and "thermal" means heat. So geothermal means earth-heat. Geothermal energy is quickly becoming a popular source of energy and GreenDustries believes tapping into what the earth creates naturally - with little manmade influence - should be at the forefront of any energy policy moving forward.

The power of the sun. Free energy.

Solar energy, radiant light and heat from the sun, has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar radiation, along with secondary solar-powered resources such as wind and wave power, hydroelectricity and biomass, account for most of the available renewable energy on earth. Only a minuscule fraction of the available solar energy is used. To us at GreenDustries it seems such a waste that something as valuable and as powerful as the sun should be admired for the growth of plants and even the growth of humans but should be neglected for its ultimate ability to provide the one thing we so sorely need: natural energy.

Where do fossil fuels come from?

With fossil fuels - their costs and their toll on the environment - controlling our lives, GreenDustries thought it would behoove us to take a look at the major forms of fossil fuels and where they come from and the delicate balance of nature that falls in between.

There are three major forms of fossil fuels: coal, oil and natural gas. All three were formed many hundreds of millions of years ago before the time of the dinosaurs – hence the name fossil fuels, according to the website Read more [...]
