Other advantages: floodproof up to 70 cm and “Option Venezia”






Climate change increases flood risk globally. Far more incidents in low-risk and moderate flood-risk areas. The GEMINI next Generation house is floodproof up to 70 cm and will be able to swim for a 20,000 € upgrade called “Option Venezia”. Most homeowners will make the decision based on insurance tariffs: What is cheaper, the down payment for “Option Venezia” or the flood insurance? BTW, we thought about a special possibility to make the photovoltaic hailproof. The idea was dismissed after it turned out that this design would be 10 times pricier than the hail insurance. Studying risks is a main job of running an insurance company, so any design avoiding a risk can only be successful when it is cheaper than insurance. On the other side, fire insurance in California is so expensive that an advanced fire protection system would be far cheaper. When we will be there, we will call it “Option California.” Other advantages: floodproof up to 70 cm and “Option Venezia” Most homeowners will make the decision based on insurance tariffs: What is cheaper, the down payment for “Option Venezia” or the flood insurance? The settlement, shown before, at 4.5 m flood. All houses swim. The central structure is fixed, so all garages and parking platforms had been brought outside to swim.

  Cost optimization — the key to energy transition and climate protection
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 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 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? 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.
