Revolutionizing home financing

Energy income instead of energy expenditure is the key to making a home affordable again. The difference can easily finance a €150,000 home loan.

We compare rental apartment, conventional house and GEMINI next generation house over 40 years. We asked Grok about inflation in Austria in various areas from 1995 to 2025. Because we are not in a position to forecast inflation rates from 2025 to 2055, the calculator simply shows those from 1995 to 2025.

Experiment with the inflation rate forecast, enter different values for expenditure.

General inflation
Diesel, gasoline
Electricity
Rent for an apartment
Operating costs for an apartment
Water, sewage, waste, property tax
Increase in income
Current interest rate for home loan

Inflation-adjusted expenses

The monthly expenses for housing and energy costs for mobility are corrected with the general inflation rate. The increase in rental housing takes place because the price increase here is above the general inflation rate.

Attention! These figures apply to Austria. In other countries, inflation, credit interest rates, solar yield, electricity markets may vary considerably.

GEMINI next Generation AG (Inc.)
	We improve the world through Climate Protection Superiority Houses. Our mission statement: planet renovation back to 350 ppm CO2, we contribute house by house.

We are the counter movement
	Many people feel that there is a development in the wrong direction in many areas. We are more than only an innovative product, we are the countermovement.

Home ownership cheaper than rental apartment
	Everyone understands that a smartphone from 2022 is much cheaper than the first mobile devices from 1990 and also much better. We show that this is also possible for houses.

Our proposals and topics for discussion with policymakers
	Policymakers can only work with what is possible according to the state of the art. We are drastically shifting this state of the art and thus creating new possibilities.

Housing turnaround and energy turnaround
	Urbanization has been underway since the 1st industrial revolution. An efficient energy transition and a higher standard of living require a reversal of this trend.

The fundamentally different philosophy behind the product
	The way of thinking determines which product developments are possible at all. Mental barriers can be much more important than technical ones.

2022 Establishment of a corporation to 1. capital increase
	The foundation of GEMINI next Generation AG and the preparation for the first capital increase. Step by step on the way to the next big disruption that redefines what a house must be able to do.

2023 from research and development towards realization
	The goal for 2023 is to prepare for the construction of the first factory hall in Unken in 2024 and the remaining development work on the house and production technology.

2024 Capital increase and cooperations for the development of components
	The goal for 2024 is to achieve the necessary capital increase, cooperation for the development of components and the prepare for the construction of the first factory building in Unken in 2025.

2025 less capital required and faster realization
	A meeting at the Munich construction fair with a company from Banská Bystrica brings a big leap forward towards the realization of the prototype.

More than just a house - a way out of a nightmare
	If all the fans of the German energy transition were really interested in a successful energy transition, then the AG 2025 should already be much further along.

Lecture at the CORP.at conference at the Joanneum
	On 16 April 2025, I gave a presentation at the CORP conference in Graz on energy-optimized settlement areas and the overall scope of our project.

Even more photovoltaic peak power
	The efficiency of photovoltaics for the mass market has increased further. The GEMINI standard house with double garage exceeds 50 kW peak for the first time.

Thuringia Investor Days
	Solutions for affordable and comfortable living, functional and cost-optimized energy transition are undesirable. But what are the criteria then?

Prototype financing round
	When the prototype is ready, we will invite politicians and industrialists from all over the world to demonstrate our solution in the field of housing and energy.
