Ventilation systems with heat and moisture recovery
Extremely economical and quiet, yet large power reserves to have the best indoor air quality even at a large party. Is of course part of the basic equipment.
For 3 decades I have observed that ventilation systems with heat recovery almost do not spread because of absurdly high prices. Here I explain why a ventilation system, which every ventilation engineer would call “The mother of oversizing”, is the most economical solution and belongs to the basic equipment of a “GEMINI next Generation” house.

| 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.

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.

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.

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?

How can you achieve a higher COP with an air-source heat pump than with a ground-source heat pump, and how can you drastically reduce the amount of electricity needed to heat water?

| Disruption at houses
|
| 
|
|
|
The market for homes is in as horrifying a state as the electric car market was in 2003: in the year Tesla was founded, the Peugeot 106 was a top electric car.

or how a house shrank to 2/3 of its size. Because of this visual misunderstanding, the video “Disruption in Houses” was published again with improved graphics.
