Comment Re: So negative test couldn't have been flawed? (Score 1) 253

The WHO estimates that there have been 765M total global infections. Keep in mind that only about 1 in 20 infections is actually confirmed. While it's safe to say that people who recover from it are "Immune", we don't really know how long that immunity lasts, or how much the virus will change in the future.

Presumably, Trump was referring to the average overall death rate of the flu being 0.1% and the CDC estimated Coronavirus death rates by age: 0-19: 0.003%, 20-49: 0.02%, 50-69: 0.5%, 70+: 5.4%. People under 50 are less likely to die of COVID-19 than the 0.1% overall flu figure. While this doesn't stand up to an age breakdown of flu deaths, it does draw attention to the very low death rates of COVID-19 for people under 70.

They seem to be talking about the individual battery cells. This would be a 46800 cell vs. an 18650. Obviously, putting more more energy-holding material and proportionately less packaging into a cell is going to make it more efficient. The car will use fewer of these bigger cells. Why didn't they do this years ago? Was it not practical? Why don't they make the cells even bigger?
