What's next for Starlink (direct to cell, revenue)?
“The ridiculous arguments by Ambani’s army of Internet shills make no sense On the one hand, they say Starlink couldn’t possibly compete with the amazing low prices offered by Ambani’s de facto monopoly in India and then, in the same breath, they essentially claim that Starlink would be too strong of a competitor! This is absurd hypocrisy and hyperbole. The reality is that competition would greatly benefit the average citizen in India by giving them more choices, as it always does. Ambani’s profits will be lower, but he is not going out of business. And, obviously, if Starlink is too expensive in India, no one will buy it, so SpaceX will need to make pricing affordable.”

What's next for Starlink (direct to cell, revenue)?
“Starlink will be of great help to areas of India that have bad or no Internet and even no mobile coverage. No country has perfect coverage, including America, but Starlink can fill in the coverage gaps for those who most need it.”

What's next for Starlink (direct to cell, revenue)?
“There will also ultimately be >100k V3/V4/V5 satellites for Starlink broadband and direct to cellphone connectivity. If growth continues, Starlink will one day carry the majority of Internet traffic. At that point, it is the Internet and everything else just connects to Starlink.”

What's the future of energy (solar, batteries)?
“Very few people realize that Europe’s entire electricity needs can be met with solar panels covering an area less than the size of the island of Sicily! Battery packs can cover the energy needed during the night.”

Q1 2025 call: why grid batteries matter
“If the power plants could operate at peak power for all 24 hours, as opposed to being at half power, sometimes a quarter power at night, then you could double the energy output of existing power plants.”

What's next for Starlink (direct to cell, revenue)?
“The first Starlink satellite direct to cell phone constellation is now complete. This will enable unmodified cellphones to have Internet connectivity in remote areas. Bandwidth per beam is only ~10Mb, but future constellations will be much more capable.”

What's the future of energy (solar, batteries)?
“Earth already receives about the same energy from the Sun in an hour than humanity consumes in a year. Solar panels just need to catch a tiny amount of it to power our entire civilization!”

Can a Powerwall and rooftop solar take you off the grid?
“And if you have enough rooftop solar, you can go off grid for most of year in high latitudes & whole year in low latitudes”

Why is Tesla focused on iron-based battery chemistries?
“There are vast amounts of iron (and lithium) on Earth, but much less nickel. For global industry to scale battery production to ~10 TWh/year, it needs to be mostly iron. Higher energy density of Nickel only needed for very long range vehicles & aircraft.”

Why is Tesla moving standard-range cars to iron-based cells?
“Nickel is our biggest concern for scaling lithium-ion cell production. That’s why we are shifting standard range cars to an iron cathode. Plenty of iron (and lithium)!”

Will raw materials like nickel limit battery production?
“So in order to scale, we really need to make sure that we're not constrained by total nickel availability. I actually spoke with the CEOs of the biggest mining companies in the world and said, "Please make more nickel, this is very important." And so I think they are going to make more nickel.”

Does making a Model S battery produce 8 years' worth of gasoline-car CO2?
“Calling this cueless would be generous. Much less energy required for lithium-ion batteries & Gigafactory is powered by renewables anyway.”

Does a Model 3 take more CO2 to produce than a gas car?
“First approximation of CO2 is production cost, factoring in energy source, so Model 3 obv less CO2 to produce than $35k gas car by a lot”
