Climate, energy, nano:
The big issues of the future.
Climate skepticism and climate fear.
The truth lies in between.
Man-made global warming is a serious problem and the reports of the Intergovernmental Panel on Climate Change (IPCC) scientists summarize well the available knowledge on this challenge. 4π continuously studies the extensive data collections of the Intergovernmental Panel on Climate Change as well as the other relevant technical publications on this topic. Our speakers provide audiences with a presentation of this scientific knowledge that is understandable to laypersons. 4π sees itself as a mediator between climate skeptics, who doubt that humans can change the earth's climate, and climate alarmists, who give humanity only a few more years until it is too late. In the process, 4π also answers a wide range of detailed questions, such as the regional consequences of climate change for agriculture or disaster prevention. The company attaches great importance to objectivity and realism without alarmism.
How efficient, economical, safe, and future-proof
are the new forms of energy?
Generating enough energy is the key to a bright future. The industrial revolution began with the development of the steam engine, which can convert the heat of fire into work. To this day, combustion engines in automobiles, power plants and airplanes form the basis of industrial societies. Climate change now makes it necessary to phase out fossil fuels. The good thing is that we are currently experiencing a real surge in energy development. The variety of new ways of extracting, storing and transporting energy is enormous, and it is difficult to distinguish between physically sound and less sound approaches. Often, in the enthusiasm for the new technologies, important aspects such as affordability, security of supply, sustainability, and even the potential dangers are neglected. 4π observes the diverse developments and can provide background information and evaluation criteria for each of these new ideas.
Nano is beautiful. - The future starts downward
from a ten-thousandth of a millimeter.
We are at the dawn of the nano age. Until the turn of the millennium, man mastered manufacturing with an accuracy of up to one thousandth of a millimeter. With this precision, car engines, airplanes and solar cells can be built. But there is a whole world with its own laws of nature that is much smaller still. The nanoworld begins below one tenth of a thousandth of a millimeter. Humans are just beginning to explore this new territory in the first steps. The first products of the nanoworld are smartphones and quantum computers. But this is just the beginning. Diseases like Ebola, Covid-19 and cancer are based on processes in the nanoworld. Sooner or later, they will be defeated. Nanotechnology has tremendous potential to change all of our lives. Society must adapt to it. 4π informs citizens about developments in all sectors of nanotechnology and nanobiology. As with any tool, what you do with it matters. With enough background information, society will succeed in using the new possibilities for good.
A better future? - We believe in it!
How will we live in 100 or 500 years? One vision is an eco-society in which people return to a life in harmony with nature. Another vision is an overheated planet where only a few people will be able to eke out an existence. A third vision is a high-tech civilization that offers the many billions of Earth's citizens a varied life in gigantic megacities. Will these people ever reach the stars? In addition to these fundamental questions, there are also pragmatic questions: Will there still be cars? Will democracy survive or will there be a relapse into dictatorial forms of government? What can we do now to positively influence developments? 4π deals with these questions and similar issues on the basis of a global, interdisciplinary and ideology-neutral approach.
