Today I propose a little puzzle :
a airtight room with an oxygen indicator outside the door. This meter detects the average oxygen level inside the room, which is 20%. The value corresponds to the concentration of oxygen in the external environment, therefore in perfect living conditions. Opening the door, one finds for & ograve; a person lying on the floor and bluish in color, evidently died of suffocation. What will it be? happened?
The room was initially filled with pure oxygen – & egrave; possible to live there, even if in the long run it is not; very healthy -. But after a few hours, all the oxygen in the room was consumed and replaced by the CO2 in the exhaled air. At that point the breathing is; became very tiring.
The interesting thing for & ograve; & egrave; this: all in all, in terms of overall balance the average oxygen content for the entire period of time was ok, yes & egrave; always kept in safety levels. But this did not help the poor fellow at all, because & eacute; & quot; overall balance & quot; & egrave; a purely statistical consideration that doesn't work in practice.
WHEN ENERGY? REALLY GREEN?
This is; exactly what happens with low carbon electricity & ndash; l & rsquo; electricity green. Even today, in almost all; of cases it is a low cost labeling scam , because & eacute; & egrave; green only in terms of the overall balance sheet, and usually only in terms of the “ overall annual balance sheet ''. There & ograve; it becomes particularly evident if we consider, for example, a solar installation in our European latitudes. In summer, during the hours of light, the plant will provide; much more energy than we can use, while in February the roof panels produce almost nothing and at night do not produce at all. We can continue to lie to ourselves about fueling our electric car with green energy produced at home. In reality, however, during the day we contribute to injecting too much energy into the electricity grid, while at night we recharge our car, obviously with energy that is anything but clean.
There & ograve; that many still do not know & egrave; that self-produced energy must be fed into the grid at the same time it is consumed . So, if we want to recharge our car in an ecological way, we must resort to controllable green energy sources, such as hydroelectricity, or intelligently store our electricity; coming from renewable sources. This can be done on a daily basis with a domestic energy accumulator, but seasonally only with a central storage facility, for example by converting the energy into hydrogen.
The decisive factor, however, is ; that the population first acquire awareness that simultaneity of input and consumption of energy & egrave; there & ograve; making electricity really green. To make this process visible and verifiable, & egrave; recently introduced a certificate for power plants and energy suppliers: www.truetime-certificate.com. & Egrave; was established as a non-profit organization and & egrave; finally a first step in the right direction, which I also support personally.
If you also think that the energy transition will have; success only if we stop deceiving ourselves, then please join us and help make s & igrave; that more and more; people strive to achieve simultaneity.

He has always had a practical inclination, so much so that he dropped out of school shortly before high school graduation; to follow a business administration course at the university, and then move on to the IT sector soon after. But this was not enough for Christoph Erni: he wanted more! About 20 years ago he founded his company he & agrave; of business consulting, Erni Associates AG.
In 2014, noting the lack of suitable charging solutions, he decided to enter the manufacturing sector and founded Juice Technology AG. In its first year of business, the company became established. secured pole position in this segment with the 22 kW Juice Booster 1 portable charging station, and has been since then; remained there.
