In this post a technique will be described which I came across recently. This technology was developed in Germany, Berlin. With this technology the windows of the homes will function as a heating device. As this device can be controlled via mobile phone this technique could take part in the world of the smart homes. In total there are two gaps in t

This post deals with a new Swedish technology which converts wave power more efficiently into electricity. It is tested at the Orkney Islands in Scotland and provides a great opportunity for places with high waves altitutes as it uses buoys. The technology is about the up and down movement of the buoys due to the waves. With several gears this move

This post deals with a new technology from Sweden. After the great summer in Europe with its hot days it is now cold again and the heat from the various heating device is needed again emitting CO2 - emissions. It would be nice if you could transport the heat from the summer to winter times. A new technology discovered in Sweden can make it possible

This post is about a panel which combines the photovoltaic and the solar thermal technique. Normally owners of a house had to decide how they want to use their roof, either of putting solar cells onto it or installing a solar thermal energy system on it. As the new product called 2power has the advantage of combining both systems efficiently togeth

This post is about a new technology from Scotland, which uses a weight to store energy. In times when energy is required the stored energy will be put back into the grid with generators. All is needed is an abandoned coal mine. The technique is quite simple but effective: A weight is put into the mine linked to winches which can move in both direct

This post deals with a similar technique described for in my blog some time ago for storing electricity. It deals with an under water storage, in which water is stored in a balloon of concrete. It is an investigation project in which the Fraunhofer Institut in Germany participates - it is called Stensea. What can countries without big mountains and

This post is about a technology created by the company LucidEnergy in Portland, USA. The main idea is to use a energy source which is available 24/7 and does not harm the environment. One of these sources are the pipes which transport the drinking water into our houses. Lucid Energy generated a turbine, which they can install into the drinking wate

In this post a technology will be described how solar panels can produce energy at night. The technology was developed between the DLR (Deutsches Zentrum für Luft- und Raumfahrt) and the Linde AG. It uses energy storages which based on phase changing materials. To store energy over night is not a new technology as it is around for many years. But

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

This post deals with a technology from Germany. It combines a new developed heat pump with a solar roof system. Another great advantage of this system is that it is nearly invisible. Some people might think that a solar system on a roof does not really look good on aestethic measures and therefore might not invest in such a system. But with this te
