Hydrogen fuel cartridge .. let's power bikes ?

As "green" hydrogen production and storage has become an EU green deal central strategic axis, more and more innovative solutions emerge from academic and industrial players. Early this month, the Fraunhofer institute published an article presenting a prototype of what we can call "hydrogen power paste": hydrogen power paste (source : Fraunhofer institute) The principle behind is to create a magnesium hydride paste (whereas a high quantity of hydrogen is stored). When water is added to the mix, hydrogen gas is produced and can be used in a fuel cell to create electricity.  In the previously published article describing hydrogen fuel principles and applications, we mentioned that this H2 energy source was particularly suited for heavy transportation such as trains, trucks, or boats. This power paste concept is particularly interesting for light mobility or applications where there are no refill stations neither H2 storage tanks easily available. One can think of Hyd

Carbon Sources & Sinks

By not distinguishing between a fact and an opinion, by dint of confusing orders of magnitude and time scales, I wanted to find the large masses of carbon production and carbon sinks and share them here. We have included in the site under the "fact" tab the data we found in "the Project Drawdown - March 2020" and which states, by order of magnitude:   Carbon sources 1.       Electricity production                : 25% 2.       Cultivation & agriculture         : 24% 3.       Industry                                     : 21% 4.       Transportation                         : 14% 5.       Building                                    :    6% 6.       Rest                                           : 10%   Carbon sinks 1.       Land                                           : 24% 2.       The oceans                                : 17% 3.       The Atmosphere                        : 59%   What about taking another source: the book of Bill Gates, "How to avoid a

It must be Atomic !

  After long weeks of absence, I take up the pen again.  The vacations of this summer 2020 were an opportunity to discuss and meet brilliant people with whom I had the chance to exchange on what tomorrow could be like.  I have to write "could" because here, there are no exact sciences anymore, but relatively strong hypotheses. Remember the book  "The limit to growth" in 1972. The book was based on The World3 model, a system dynamics model for computer simulation of interactions between population, industrial growth, food production, and limits in the earth's ecosystems. These hypotheses tell us that the energy mix road will be 35% renewable energy and 65% nuclear energy. However, in Europe (Belgium, France, Germany), we turn away from nuclear power due to a lack of political courage or even the capacity to simply decide.  And yet we have developed all the technology.  What has become of it? The only EPR reactors (European Pressurized Water Reactor) operating are
