Volcanoes are dangerous sources of energy

Scientist use volcanoes to try to extract energy. One of their experiments was to drill into a volcano and make a well. Then after the well is made they inject cold water before the well is properly heated. The final goal is to produce high pressure superheated dry steam.
The first well that was created was called RN-17. It is located at Reykjanes area. It was first drilled to 3082 m then they drilled another 800 m. They tried to drill to 4500 m but they realized that it would take 115 days longer so they didn’t do it. When they started putting down the drillstring it came upon a molten rock 2104 m. Fortunately they pulled out the drillstring on time so everything was under control. Same problems occurred also at Krafla and Hawaii. The good thing about these studies is that researchers have the opportunity to learn more about injecting cold water into magma.

Spray on fashion

Spray on fashion
Spray on fashion is created from the company of Fabricana. It was created by a Manel Torres a Spanish designer and a professor of a partial technology Paul Lukham. It is just a spray that you spray on you and it turns into clothes, it is washable. They think that it won’t irritate a wound if you spray it on it. There are some problems that are the clothes may be to snuggle and the smell of the solvent, which is very strong and lingers around the clothing. Although researchers say that it will be solved soon. I think that this is very good but I wonder what they use to make it and if it can cause harm to earth or people. When will it come out to buy and will it be expensive and how long will it take to make a good looking shirt.
