Online calculator for the prediction of solar- and windpower farm output
A team of developers from the Imperial College London and ETH Zurich created an online calculator to be able to calculate the estimated output of solar and wind energy. There is a global data base available and more detailed for the European region. The tool can be used worldwide for free and it is a great opportunity for all planners of solar and wind power plants.

Advertising with Facebook
You have a small business and you cannot afford pricy advertising?
With a Facebook business fanpage and the appropriate advertising you can reach more than 200,000 people in Uruguay within 2-3 weeks. And that's for just 5000 Pesos! Usually that's not possible with conventional advertising and not as simple and affordable. You pay only those, who respond to your advertising, in this example the cost per person was about 3.20 pesos. And you can also be sure that the person has responded in any way to your advertising, such as with a "Like" of your page!
LED-lights made from driftwood
If you love the nature and like to stay at the sea, you will find some interesting things while walking along the beach. Of course, there is still too much waste and especially plastic waste, but sometimes one can find a few useful things. In particular we like the driftwood, because it must have experienced a lot after landing at the beach, bleached and rounded. Meanwhile everywhere in the world there are artists creating new art from the plastic stuff and for example in Kenya they specialized on the recycling of stranded beach sandals. CSTC tries to combine driftwood with modern LED lighting to recycle waste and to save energy with lighting.

Why to heat up air with solar power?
We have an average of 230 days of sunshine in Uruguay and in the winter time there are plenty of beautiful sunny days too. If you assume that on a global average about 1300 watts per square meter power from the sun reaches the earth, we should try to use this free energy. Some ways to use solar power are used already successfully in Uruguay for many years, but at the moment only for heating up water and generating electricity. The easiest way of use, the heating of air, is unkown here.

Reducing the cost of kitchen lighting to 10%
If you still want to have fun using your kitchen at the beginning of winter time, you need adequate lighting. Until now, we realized this with the usage of halogen lamps. To illuminate all the work-space evenly, we used 7 small 20W spots and a ceiling lamp with about 100W. With the increasing costs of energy in Uruguay and to reduce our 'ecological footprint', we have changed everything to LED. Meanwhile, the lamps are at an affordable price level.
