Limits of solar power

November 10th, 2011 - 

 

I was recently at some friends that had solar panels, I took a shower late in the night and I discovered some problems regarding the limitations of solar power usage. First of all, you will need more than 37 Celsius degrees in order to feel the effect of a warm water. If this is not happening, my case, I felt like taking a bath in the sea. Anyway, the shower was short, I can tell:) Searching on the internet, I found some information about the limits of solar power. The location, hours of daylight and angle of the solar panel all affect how well solar (more…)

How can I build a solar cooker?

November 10th, 2011 - 

 

Panel solar cookers are the first solar cookers that are truly affordable to the world’s neediest. Solar Ovens are cheap to make and they can be packed and ready to be transported anywhere. You will need not more than an hour to assemble these fun panels at a cost that could be less than US$5. The Cookit model who’s image you can see below can be folded and the result is a kit of a size of a notebook. In 1994, engineers and solar cooks together with Solar Cookers International worked on a project to produce the CooKit. The gadget is (more…)

Torresol Energy’s Gemasolar : Solar Power Plant

July 4th, 2011 - 

Torresol Energy’s Gemasolar is located in the Spanish province of Andalucia. Gemasolar was launched in May 2011 and it functions due to a solar salt battery that allows the system to make the most of the sun power long after the sunset. These batteries  consists of two tanks of molten salt thermal energy storage that allows the solar plant to generate on-demand electricity: a storage for days when it is raining or there are lots of clouds.
The  Molten salt energy storage (MSES) or “solar salt” batteries use potassium and sodium nitrate. These substances are much more safe and for sure cheap than other batteries. Compared to other batteries, Gemasolar  has
just doubled the availability of the batteries for 15 hours, almost double than others before. Gemasolar ’s expected production is 110,000 MWh per year—or about enough to fully power 25,000 households. Via

Renewable energy generating art installations

June 2nd, 2011 - 
 

Here are some art installations that have beautiful design but they also are examples of best energy savings.

The Lunar cubit is the winning design by the New York based team of Robert Flottemesch, Jen DeNike, Johanna Ballhaus, and Adrian P. De Luca for the 2010 Land Art Generator Initiative (LAGI) design competition. The pyramids are covered in solar panels that will provide energy for about 250 homes.The monuments will be arranged in circular form to create a huge lunar calendar.The proportions of the pyramids match those of the Great Pyramid at Giza.
The solar powered dunescape by designer Khourvy Levit Fong creates electricity also. The construction has mirror polished stones towards the sun. Concave eye-shaped surfaces reflect light upon pipelines, superheating their liquid contents and powering electricity generating steam turbines housed beneath their crests.
Windnest art installation that you can see below ( the picture with tubes) is used to produce energy from both solar
and wind power.Great structure!
The solar sunflowers are built in Texas. They capture the solar energy but in the same time they function like huge umbrellas for the people of Austin that can hide from the sun during days.
Apart all these, there are eco-art installations that provide energy due to the footsteps pressure of kids jumping around in the park.

Plastikoleum Tower converts waste plastic into oil

June 2nd, 2011 - 
 

The Japanese inventor Akinori Ito sells convertors machines that can transform plastic waste into raw petroleum that can be then converted into gasoline, diesel or kerosen fuel. The Japanese have created many sizes of these convertors and he train people to recycle plastics with a small desktop convertor version like this one:



His company, Blest Corporation, sells various scales of his converter from 1kg capacity to 50kg. The device can produce 1 liter of oil from 1 kg of plastic waste material. Starting from this point, there is this Plastikoleum Tower project that aims to improve this idea and to recycle plastic on big scale: I mean tones of plastics a day, using solar power. And all this because the converter Akinori created consumes a lot of energy in the process.The latest technologies are
very efficient when it comes to using solar power. While most solar towers are generally sized at around 20MW capacity, the Plastikoleum Tower is rated at 10MW. At 10 tons per hour capacity these towers could produce around 60 barrels of oil every hour. Via
