      "To achieve this level of decentralization and immutability, ION is built on top of the shared database that's used for recording bitcoin transactions, which is known as the blockchain. Though Microsoft is contributing most of the work, the company would have no control over who participates in the system."

      Imagine an aircraft engine that has no moving parts, produces no harmful exhaust and makes no noise. That's what researchers at the Massachusetts Institute of Technology (MIT) in the US have created by adapting a technology previously only used in spacecraft so it can power flight over the Earth.
      Ion drives have been used on spacecraft since the 1960s and work by firing out a stream of charged particles that propel the vessel forward. As well as being carbon neutral, they are less likely to go wrong and cheaper to maintain than conventional engines because they have no propellers, turbines or fuel pumps to break down. The only problem was that, in Earth's gravity, the thrust produced by the drive wasn't enough to overcome the weight of the batteries needed to power them. Until now.
      The timely new research, published in Nature, paves the way for the possibility of silent drones in the very near future. With further advances in materials and power conversion, silent crewed aircraft and eventually commercial flights could also be on the horizon. In fact, this breakthrough could be the first step in changing how we all fly around the world in the future. 
      All aircraft engines work by pushing something backwards so that the craft moves forward. Usually this is air, whether cold air driven by electric propellers or hot air fired out by jet engines. Ion propulsion instead sends out charged particles or ions generated in the gap between two electrodes with a high voltage inbetween. The ions interact with the air, creating an ionic wind that is sent backwards, propelling the aircraft forward. 
      As with propeller-driven solar powered aircraft, ion drive craft are powered by electricity and so don't need to carry fuel, other than batteries filled with charged particles. The new research shows that, with some clever modifications to the battery setup and the way the electrical power is converted, it's possible to reduce the battery weight enough to make this technology fly.
      Compromise design
      A craft with an ion drive also needs a large front area to generate the ionic wind in the right way. But this would usually make the aircraft heavier, so the researchers had to balance these conflicting limitations. They designed a wingspan that was small enough to reduce risks and make the testing cheaper and easier, while being large enough to use standard remote control components. 
      The researchers flew ten flights using an aircraft with a 5-metre wingspan, weighing less than 2.5 kilograms. They were able to fly it for up to 9 seconds over a distance of 45 metres at a speed of 5 metres a second. The craft needed around 20 seconds to build up its power and was then launched using a mechanical bungee system.
      While this flight time and distance might not seem like much, the researchers point out that they're actually similar to the those of the first flight of aeroplane inventors the Wright Brothers in 1903. Making further advances in materials and power electronics, and optimising the airframe, could enable the craft to fly faster and for longer. It may also be possible to use solar panels to generate the electricity needed to power the ion drive.
      One of the big advantages of an ion-powered craft is its near-zero levels of noise. So it's likely the technology will find its first application in silent drones. Its lack of moving parts should make it relatively easy to scale the system down for smaller craft and make it easier to scale up. But bigger craft will also need a bigger increase in power. To build an ion-powered airliner you would need to increased the amount of power relative to the craft's size 300 fold. 
      But look how far we have come since the Wright Brothers' first flight. The sky may be the limit with this new technology.

      Bonsoir Jpl
      Je recherche un discours qui avait pour thème " Dieu approuve t'il toutes les religions ? " C'est pour mon etudiante de la Bible. Si tu l'as écrit ou oral, peu importe, c'est pour qu'elle puisse l'écouter
      Merci beaucoup ! 
      Ta soeur dans la foi

      Daniel 12:6 Jehovah sends an angel to ask another angel: “How long will it be to the end of these marvelous things?” The other angel "the man clothed in linen" is inspired by Jehovah, raises both hands to Heaven and answers twice! One at verse 7, then verses 11 & 12. Just as the angel raises both hands to Heaven, there are 2 fulfillments, there are 2 beasts, the first dies, but rises again with greater power today. This who Jesus spoke about at Matthew 24: 15 “Therefore, when you catch sight of the disgusting thing that causes desolation, as spoken about by Daniel the prophet, standing in a holy place (let the reader use discernment). 
      Today we can use discernment as we see the dashing to pieces of the “power” of the holy ones in the hindrance of the “public” ministry caused by Covid19. We will see a greater attack on that ministry of Spiritual Israel under the rule of the King of the South as the world turns on religion. 
      Jesus stated that no man knows the day or hour, that was true then, because only Jehovah knew how long He gave Satan to prove his point. Only Jehovah could look into the last days and see when the constant feature would stop, the days are counted from then until the first day people will enjoy true happiness. This is the most important day to live for.
      John 4:23 states "Nevertheless, the hour is coming, and it is now, when the true worshippers will worship the Father with spirit and truth, for indeed, the Father is looking for ones like these to worship him." Why is God having to search for "True Worshippers"? Because the world is almost all "False Worshippers", denied understanding as stated at Daniel 12:10.  It's amazing how He has hidden the truth from minds, religions formed before the last days were formed without all the facts, even though they could read it over and over, because of their heart’s inclination, He has hidden the facts from them. How the primary resurrection will occur on Earth, that the land would be apportioned out to those choosing to live as a subject of the sovereignty of the Almighty God Jehovah. 
      Jehovah longs to talk with His friends of old like Noah, Abraham, David as well as Daniel. Daniel has seen Michael/Jesus stand up and the start of the resurrection which will benefit him, how he will stand up for his lot. verse 13. God has promised them the "Promised Land", a greater land then the small area of Israel, the whole planet will become a blessed restoration of the Edenic starting place. Matthew 19:28 Jesus said to them: “Truly I say to you, in the re-creation, when the Son of man sits down on his glorious throne, you who have followed me will sit on 12 thrones, judging the 12 tribes of Israel. Consider too Acts 3:21 "Heaven must hold this one within itself until the times of restoration of all things of which God spoke through the mouth of his holy prophets of old." The true reward that so many have hoped for now has a starting date!    
      If you have given your life to Jehovah and enjoy a relationship with Him, Read and Meditate on Daniel 12, pray for insight and understanding, for knowledge, wisdom, for faith and integrity for the days ahead!  For whether we live or die, we belong to Jehovah and will enjoy our lot just like Daniel.

      Bonjour Gilles
      As tu les transcriptions des autres jours de l'Assemblée régionale stp ? Notamment la partie sur la création et les huit exemples de femmes de foi?
