On Wednesday, December 9, Starship serial number 8 (SN8) lifted off from our Cameron County launch pad and successfully ascended, transitioned propellant, and performed its landing flip maneuver with precise flap control to reach its landing point. Low pressure in the fuel header tank during the landing burn led to high touchdown velocity resulting in a hard (and exciting!) landing.

Prominent Energy Researcher Believes In Electric Trucks Over Fuel Cells

In the Hydrogen-Battery War, the tide is turning in favor of batteries. Automakers have recently dropped plans to develop fuel cell passenger vehicles.

(..)“But my research in the Netherlands has revealed that 80 percent of trucks—even the really big rigs, the semis—travel 750 kilometers per day at the very most, and many cover far shorter distances. That’s because if you want to cover more kilometers, things become very expensive very quickly, because you have to pay overtime, etc. So, in general, you can’t make a driver do more than 750 kilometers per day. Therefore, this is the range you have to hit with about 80 percent of trucks.”(..)

(..)What about synthetic fuels? “As far as I can tell, e-fuel trucks have one single big advantage only: they run on very energetically condensed fuel. But in terms of efficiency, in terms of maintenance, and in terms of price per km, they are highly inferior to battery-electric trucks. Both the production of e-fuels and their use in combustion engines are highly inefficient. Overall, e-fuel trucks need 4-5 times the energy required to power an electric vehicle. That’s why I don’t see that option going anywhere.”(..)  

(..)“The same is true for hydrogen, but to a slightly lesser extent. Fuel cell trucks will remain much more expensive to operate. That’s because we have to make hydrogen from electricity, and we lose at least half of the energy in the process. Therefore, you will definitely need twice as much electricity to power a fuel cell truck than a battery one.”

No necesitas ser bueno en los bolos si eres bueno en ingeniería.

Hice una bola de bolos con James Bruton, que se mueve hacia la izquierda o hacia la derecha, en función de tu inclinación. Las personas suelen inclinarse cuando juegan a los bolos para intentar cambiar la dirección, así que aprovechamos eso. Funciona con los mismos principios que una bola BB8.
