Shopping Malls
At the edges of cities, one can see the development of stores in corrugated metal (or metal cladding) warehouses — with ground-floor layouts and extensive parking lots in front, behind, or surrounding them. These prefabricated structures offer significant cost savings and rapid construction. The investment per square meter is substantially lower than that of an architecturally…

We are breathing uranium
Uranium is not used responsibly. It is used in ammunitions during war. When ammunition explode, uranium is dispersed into dust that is carried by the wind or spreads into waterways. We are all polluted by wars, even those far away. It is used in agriculture to sterilize crops. Farmers are the first victims because they…

Our understanding of how the brain and AI (Artificial Intelligence) work has advanced considerably. The best model of the human brain we have today dates from the 1970s and is based on neural networks. For each characteristic, a knowledge or emotion is associated. We reconstruct concepts whenever we need them. Our memories are linked to…

Stop the all-concrete approach
Concrete dominates today’s buildings. And yet it has major shortcomings. It consumes a lot of water and energy, produces a lot of CO2 and lasts only 80 years at best for reinforced concrete. What’s more, it doesn’t provide sufficient protection from the heat, leading to excessive increased use of air conditioning, which in turn exacerbates…

Fund
According to the 2019 International Monetary Fund (IMF) report on energy subsidies, “fossil fuels account for 85 percent of all global subsidies,” and reducing these subsidies “would have lowered global carbon emissions by 28 percent and fossil fuel air pollution deaths by 46 percent, and increased government revenue by 3.8 percent of GDP.” – Global…

Why wait 2000 years to adopt a natural and more efficient way to grow food?
“The recycling of organic wastes was perfected over centuries in Europe. But their Nitrogen content is only 0.5% and the heavy labor of collecting and distributing up to 40 tons of wastes per acres of city execra resulted in an overall loss of 60% of energy loss per cultivated acre. Green manuring was used by…
