Si le temps ne se déroulait pas de manière linéaire ?
Il n’y aurait pas de début nécessaire, ni de fin inexorable.
Le big-bang aurait peut-être eu lieu mais en Read more
Science or dogma at the National Geographic Society?
One of the most a-scientific articles about science that I ever could read. Poor contribution of the National Geographic Society to the enlightenment of its members. Read more
Sortir du nucléaire au détriment des générations futures ?
La sortie du nucléaire a été décidée. Mesure-t-on toutes les conséquences de décréter une technologie de pointe comme prématurément obsolète, ainsi que les compétences, connaissances et expertises qui lui sont liées ? C'est une manière de couper définitivement la branche sur laquelle on est assis, se rendre dépendant et intellectuellement pauvre, auto-goal incohérent, désastreux et irresponsable. Read more
Petrol, hydrogen, hybrid, or all-electric?
Comparison is made of the energy use of various types of cars. The hybrid powered vehicle wins the race, with the added advantage that no new infrastructure is required. Hydrogen, a hazardous explosive gas, is definitely out of question because of large inefficiencies during its production and its use. Read more
My position on the climate
It is true that, to understand something about the climate controversy, one must devote time and attention.
For those who trust me in my ramblings I summarize here my position, it is quite clear. Read more
MR-climate: internet site re-launch
The climate questions are far from being settled, neither in their causes and effects, nor regarding actions to be taken, or not to take. The internet site MR-climate has been totally renewed with many additions, calculations, and insights. With a forum for, hopefully, more in depth discussions. Read more
Climate change: if and when all proved reserves of fossil fuel will have been burned.
If and when all proved fossil reserves will have been burned, the atmospheric carbon dioxide concentration may reach approx. 925 ppm. At this level the temperature impact is calculated by a simple two layer static model to be 0.9 to 1.2 °C above its level before the beginning of the industrial era. This is clearly no reason to terrorize the crowds with catastrophe scenarios. Read more
Intermittent energies: an alternative to nuclear and to carbon dioxide?
Apparently we must reduce CO2 emissions.
This requirement has become a higher true and immutable dogma.
Also, following the fears felt after Chernobyl and Fukushima, countries are now committed to phasing out nuclear power. This has also become an almost moral imperative .
Yet I'm taking on the immeasurable task to put these issues on the table, what heresy! Read more
