Ventilation system with heat and moisture recovery
On May 13, the last of the ordered units is ready for pickup at a forwarding company. The trip was nearly for nothing, because the device only barely fit through the tailgate.
In Suben in Upper Austria at the DSV freight forwarding company: Does it fit? No, it doesn't fit. First the packaging has to be removed.
Got in by a hair's breadth!
The same amount of air can be moved much slower through 200 mm pipes than through 150 mm or 120 mm pipes. Lower air velocity means quieter and less power for the fan.
This 500 m³/h model has 10 fan speeds. In the GEMINI next generation house, it will mostly be operated in the lowest stages. Only if the air meter measures very bad values, then there are plenty of reserves upwards to increase the air exchange.
The same device is also intended for the greenhouse. If there are no unwanted intruders coming in through the HEPA filter, then there is no need to fight them.
|GEMINI next Generation - energy + food + living comfort|
|What can housing cost? Where can you build? How much Energy should a house produce? How much building material is needed? GEMINI n.G. is looking for completely new answers to these questions.|
|Prehistory of the GEMINI next Generation project|
|It started in autumn 1991 with the GEMINI habitable solar power plant, 2011 with the initiative Solar Building Land and 2018 with GEMINI 66 - we build our house ourselves.|
|Where can and should GEMINI next Generation be built?|
|Using existing land better and building where conventional houses cannot or are not allowed is an important objective of the GEMINI next Generation project.|
|How much energy should a house generate?|
|As much as possible! Because we need to get out of oil, coal, biofuel, natural gas and uranium. Our houses should contribute as much as possible.|

|The heat pumps have arrived|
|On December 16, 2020 paid, on January 27 the ship arrived in the Slovenian port of Koper. On February 19, the 3 heat pumps could be picked up at a forwarding agency near Salzburg.|
|The Green parliamentary group in the German Bundestag is hosting the online conference “Rethinking Cities” on March 19, 2021. We are participating in the virtual exhibition.|
|The LiFePo4 batteries have arrived|
|Ordered in mid-December, arrived on March 19. Low costs for electricity storage are a decisive factor for a real energy transition.|
|Rethinking the energy transition: The price lie|
|The demand for “more money for climate protection” is based on the price lie. But we need more motivation, credit and opportunity for a real effective energy transition.|
|Summer / winter balancing of solar power - seasonal storage|
|Different approaches to summer/winter balancing compared. Seven different locations, from Oslo to Cairo, are examined for seasonal balancing.|
|Energy change - Food change - Social change|
|Everyone is only talking about the energy transition for climate protection, but we also need a change in food production and in the social sphere. A solution for all 3 changes.|
|DIY test of thermal insulation of an alternative building material|
|Construction wood prices are rising dramatically spring 2021 and there are supply problems. But wood prices for other applications, such as this material, are falling slightly.|
|Would Germany be possible with 100% solar electricity?|
|The expansion of wind energy is faltering. Is wind energy really indispensable for the energy transition or would it even work with exclusively 100% solar power?|
