Paper written for the CORP.at conference March 22 to 25, 2026, in Vienna. My 2025 participation was a last-minute action, but now I have much time to prepare the paper.
| Abstract
|
|
|
To meet the necessary cost optimization targets, we cannot hold the energy problem separate from all other problems: another major problem is housing.
|
| Introduction
|
|
|
Many imaginations about our future had been created in the past with completely different parameters. Unchecked conclusions from the past endanger our future with unbearable costs.
|
| My personal experience with a profitability transition
|
| 
|
|
|
Birds can fly without knowing all the terms of aerodynamics. I reacted with my design change to an ongoing “profitability transition” without knowing the term at this time.
|
| Energy transition
|
|
|
The long way from random electricity from sun and wind towards 24×365 electricity. Overseen profitability transitions have to be considered as major accidents.
|
| Solar yield and conversion to 24×365 electricity
|
|
|
The wide range of solar yield becomes much wider after the conversion of gross yield to 24×365 electricity. 6 examples from our research of 50 locations.
|
| The GEMINI principle: double usage of land
|
|
|
No better solar power plant, no better housing possible on the same ground is the ultimate target of the GEMINI principle.
|
| Off-grid fast charging settlements
|
| 
|
|
|
It can start small, somewhere in a village, with a single GEMINI house with a big PV carport and 100 kW DC charging.
|
| Energy-intensive industry
|
|
|
I once developed a scale for off-grid solar possibilities depending on photovoltaic size. But now is to make a big jump upwards on this scale: running, energy-intensive industry.
|
| Agriculture: How many square meters does a human need for his food?
|
| 
|
|
|
Mankind started as hunters and gatherers. 12,000 years ago, 500,000 m² to 2,500,000 m² per human. With the agricultural revolution, the land use was reduced by 2 magnitudes.
|
| Conclusion
|
|
|
All parameters are in a constant state of change. We have to check all the parameters and predict the development for the predictable future.

Timika has a tropical rainforest climate (Af) with heavy to very heavy rainfall year-round. It seems Salzburg is a very sunny city compared to this. It seems from 2005 to 2020 not one sunny day from dusk to dawn. Despite this more or less cloudy weather, there is still 63% more 24×365 yield than in Salzburg.
