Could some of our misgivings about Elon Musk\u2019s new electric truck be alleviated by secret energy storage advances? Perhaps, if a new report is to believed.<\/p>\nBoston Dinamics ha desarrollado un\u00a0 Robot Humanoide de dos patas, el cual ha logrado realizar un salto mortal hacia atr\u00e1s, obteniendo una asombrosa estabilidad. Ha podido caminar\u00a0por las laderas nevadas, atravesar caminos rocosos y asegurarse que si se cae lo hace de manera controlada. Esto tendr\u00e1\u00a0una gran cantidad de\u00a0aplicaciones en el futuro de los robots, tales como\u00a0en actividades de\u00a0rescate o en el \u00e1mbito militar.\u00a0\u00a0\u00a0<\/p>\n

One of the chief concerns with Tesla\u2019s electric truck is the resilience of its batteries: most lithium-ion cells for vehicles begin to degrade after 1,000 charges, which would only allow the\u00a0semi to cover 500,000 miles on a set. Problem is,\u00a0as we\u2019ve explained<\/a>, the truck\u2019s batteries may be so expensive\u2014costing as much as $400,000\u2014that its fuel savings would only allow it to break even against a diesel if it could cover 1 million miles in a lifetime. Without some kind of advance, then,\u00a0it’s going to be a very hard sell.<\/p>\n When Musk unveiled the truck, he said that it would be good for 1 million miles, but nobody thought that applied to its batteries. Now,\u00a0Axios cites sources<\/a>\u00a0who claim the cells will undergo 2,000 charges, which would indeed allow its cells to help it cover that 1 million miles.<\/p>\n How it will do that, exactly, is another question\u2014to which the Axios report doesn\u2019t have many firm\u00a0 answers. Electric truck rival Nikola Motor Company has\u00a0suggested on Twitter\u00a0<\/a>that the semi\u00a0may use batteries like those in Tesla\u2019s grid storage batteries, rather than those found in its cars, as they\u2019re more \u00a0robust. Or there may be some more fundamental battery tweak that allows them to last longer. Hard to tell.<\/p>\n But given how hard battery science is (see \u201cWhy We Still Don\u2019t Have Better Batteries<\/a>\u201d), color us skeptical until we\u00a0get some hard numbers\u00a0from Musk.<\/p>\n
