This post is about a product which can be used inside buildings to save money. Have you ever heard of energy saving paints? If not you might be interested in getting to know that these exist and how they work. When I visited the energy fair in Frankfurt in 2013 I came across one stand which produces this paint. In this text the material from the co

Yesterday I went to a lecture about the desertec project in Kiel, Germany. This speech was about the economic and political impacts for the involved countries and was organized by the Institute for World Economy and the CAU (Chrisitan-Albrecht University). The desertec project is about providing electricity in the desert of the north African countr

In this post a technology will be described which can be used to save energy. As there are times when e.g. windfarms produce so much energy that the grid can not take the load the energy need to be saved somewhere (or the windfarm has to stop producing electricity - but that should not be an option as everyone wants to have green power). The techni

In the past weeks I measured my energy demand in my room, how much I use and how I tried to optimise it. All began when I realized that I did not switch off my amplifier when going to bed. It is connected with my Laptop and my CD Player so that I can listen to music. But that I forget to switch it off each night was quite disturbing and I wanted to

After a longer idle time I decided to reactivate this blog. In this article the topic is the waste heat of servers and how it can be used. Since the past years the quantity of servers increased due to the increasing amount of data, cloud computing and the increasing use of devices like laptops, tables and mobile phones. These data has to be stored

Many humans like to listen to rock and pop music, which can improve their output due to impact of the great songs. Scientists of the Queen Mary University and the Imperial College of London have shown that solar cells response to this type of music as well. The researchers built solar cells which convert solar radiation as well as sound waves into

This technology is around for a longer time and was invented in the Netherlands. In 2007 the company was founded after making research on the sustainable dancefloor. Since then the idea has spread around the globe and 2012 the company got the projects of install the system at the Olympics and Paralympics in London. In addition the the company insta

This post deals with the gravity light. The one illustrated in this blog was invented 2013. It can be used off grid, so it can be used in developing countries and place which lack the supply of electrictiy. Normally they use petroleum lamps instead which has a bad effect on their health. But this product could help them out. It is financed my Shell

A very interesting concept for energy production came up at the University of Regensburg in Germany. The idea is that sailing boats are used to produce electricity which is stored in form of hydrogen. Until now it is still under consideration and research but it might come up in some years. All of the technologies are developed and therefore can be

In this post the technology of the radiative sky cooling will be described. In this month (09/2017) an article was published in which the Stanford university claimed that they invented a cooling system, in which the costs for cooling could be reduced drastically. The heat in this case will be transferred into space. The main technology consists of
