As I watched the delivery of the Tesla Semi to Pepsico, there was a critical moment. The critical moment was when Elon said that Tesla could charge a one-megawatt-hour battery in 30 minutes. This would take nearly a week using a regular charger installed at your house. By deduction, this meant that Tesla megachargers will have …
Tesla drove its Semi truck with a 81,000 pound payload up a 6% incline. They drove 500 miles with a full load. The Tesla Semi has a 1000 volt powertrain versus the 400 volt powertrain in other vehicles. Tesla will use the 1000 volt powertrain in other vehicles. They will have version 4 superchargers that …
The Bussard Ramjet drive has been proven not to work, but laying out a runway of fuel could work. This has been examined in more detail. Fuel is deliberately emplaced in the path of the spacecraft before the flight. Kare proposed that, at the velocities proposed for interstellar flight, nuclear fusion can be accomplished at …
A number of concepts exist for exploiting the solar wind as a means of propulsion: the MagSail, the e-sail, and the plasma magnet. All of these concepts work predominately as drag devices and thus are limited to velocities equal to the solar wind (~700 km/s), with only limited ability to generate force transverse to the …
In 2023, it will be a big mistake to ignore profits from Tesla energy, new tax credits and full self-driving software. Analysts could safely ignore energy because while it was 10% in revenue it had almost no profits. Similarly, full self driving made a lot of headlines but was only used bought by less than …
Neuralink showed off its implantable device which is slightly larger than a quarter. They showed the device working in several monkeys and they showed the surgical robot that will be used to implant the device. They are working to repair spinal damage. The current experiments are to monitor and activate spinal activity in a pig. …
Here is a three-hour talk on quantum computing and quantum theory reality and hype. Scott Aaronson is a professor of computer science at University of Texas at Austin and director of its Quantum Information Center. Previously he received his PhD at UC Berkeley and was a faculty member at MIT in Electrical Engineering and Computer …
Huge announcements in Quantum Computer Technology have been recently made and there is a clear and active path to 4000 by 2025 and 16000+ qubits by 2027. 70 error-mitigated qubits with over 50 step layers of algorithmic capability is believed to be the point where quantum computers will surpass exaflop supercomputers for cracking big problems. …
Here is a link to my Twitter space on Tesla for 2023. The main presentation and discussion starts 10 minutes after the Twitter space starts. Yes, Tesla and markets are way down but Tesla is setting up for a very strong 2023. There are large boosts to Tesla profits from full self driving sofware, inflation …
An uncrewed Orion spacecraft on a six-week mission around the Moon and back to Earth. It is currently orbiting the mon and there is live feeds from it.
IBM has a 433 qubit quantum processor called Osprey and has a roadmap for 4000 qubits in 2025 and 100,000 qubits by 2030. These are more powerful qubits than the 5000+ adiabatic qubits from DWave Systems. Most other quantum computer companies are at about 50-100 qubits. The number of usable error-mitigated qubits is being improved. …
