Optimising the energy demand of my room
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...

Façade of a house with microalgae
In this post the new technology from the north of Germany, Hamburg, is described. Here algae are used for harvesting heat and electricity. Sometimes energy production can be a bit abstract as you just see an engine, some pipes and hear some noise. With...

Self healing solar panel
This post is about a technology from the MIT in USA and it has similarities with the technique described above as it was inspired by nature. Solar panels have the disadvantage that their efficiency decreases over time. The main reason for this is that...

Energy Efficient Window
This post is about a technology which was developed in Canada, at the University of Toronto. Some researchers made a decision to look into the area of how to decrease the loss of energy over windows. As this accounts currently for around 40% of the building...

Underwater kites
This post deals with the new idea to use the energy within water streams. To harvest the energy within these streams kites will be used. The flow of oceans and water streams is very steady and in contrast to wind and solar radiation very predictable....

Heating with ice
This technology is similar to the one described in the article "(Sea)Water used for heating purposes". Have you ever heard about heating a house with ice? That’s what a company in the south of Germany is advertising. Several houses already use this system,...

Shower system saves 90% of water and 80% of energy
An amazing technology was invented by a Swedish company this year, which can save the customers a lot of money. It is related to the use of water for having a shower. In a normal household the water is heated by the heating system and then pumped to the...

Energy saving paint
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...

Controlling the light for interior lightning
Lightning of commercial buildings consume up to 21 percent of electricity consumption. As this is quite high a new technology developed in the University of Cincinnati (USA) can change this. The new technology is called SmartLight and will be described...

Wind turbine produces water
And here is again a post about water. As there are people on earth with limited access to tap water new technologies to purify water or produce water in some kind of way become very handy. Some people say that the next war will be about tap water. This...

Solar evaporation with nanoparticles
In 2012 a new technology was invented by the Rice University in the USA. Here steam is produced by using nanoparticles. This technique is meant to be implemented in the sanitation and water purification process. For quite a long time humans produce steam...

Sailing boat for energy production
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...

Radiative Sky Cooling
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...

Generating electricity from gravity-fed drinking water pipes
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...

Storing electricity under water
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...

Solar power pack - Heat pump combined with solar
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...

Solar energy at night
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...

Storing solar energy for decades
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...
-
Efficient wave power system
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...
-
Energy storage - underwater balloons
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...

Gravitiy lamp
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...
