Electric-only mineral wool production

There are Heat Degree Days (HDD). You can calculate the heat demand of a house with the energy certificate and the HDD of a location. 100 W/K and 3,900 HDD means 100 W/K x 24 hours x 3,990 HDD = 9,360 kWh/a heat demand. Most extreme permanent inhabited locations in Austria have 5,300 HDD. For example, Obergurgl. Permanent used houses there have good thermal insulation. Vienna has only half of the Obergurgl HDD. There are also Cool Degree Days (CDD). Manila has as many CDD as Obergurgl, the highest permanently inhabited village in Austria, has HDD. Single glass windows and no insulation. Rich people brag there that they spend for electricity as much as for 4 housemaids, most of the energy for this insanity is imported fossil energy. So the production of thermal insulation is something very important for hot areas. As we signed an NDA with a construction company in Ghana, my first reaction was to search for electric-only production equipment for mineral wool because insulation material is more expensive in Ghana than in Austria.

I kept hearing from building biologists about the energy required for production, but now it turns out that this is completely uncritical.

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.

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.
