Tornado Power Plant!
On the website http://vortexengine.cavortexengine i found an interesting idea about to use the energy of tornado as an effective renewable source of energy.
Tornadoes are among natures most powerful and destructive forces. In fact, tornadoes have the highest energy density of any storm in nature.
Canadian engineer Louis Michaud believes he has figured a way to use the energy of a tornado as an effective renewable source of energy. He calls it an “Atmospheric Vortex Engine.” This engine ore AVE would consist of a 200-meter-wide arena with 100-meter-high walls. Warm humid air enters at the sides, directed to flow in a circular fashion. As the air whirls around at speeds up to 200 mph, a vacuum forms in the center which holds the vortex together as it extends several miles into the sky. Michaud estimates that as much as 200 megawatts of electricity (enough for a small city) could be provided by such a system.

Stinging Nettle
In this blog post I will focus on a plant that is abundant in our nature, and which is immensely nutritious. It's of course the Stinging Nettle. Let's start with the chemical constituents of this plant:37 % Non-Nitrogen-Extracts19 - 29 % Ash9 - 21 % Fiber4 % Fat22 % ProteinOnce the leaves are drid, their protein content can reach an astounding 40 %, which is much higher than beef, which even under the best of circ**stances can never exceed 31 % protein. In addition the Stinging Nettle consists…See More

Food was bought up xawayx at once. There were no more food supplies in any shops. The economy was all crushed down. All the…See More
