Ark Invest Blew My Mind: Shocking Tesla Robotaxi Research
Ark Invest forecasts that Tesla’s robotaxi business could reach $10 trillion by 2029, driven by its manufacturing efficiency, data advantage, and strategic positioning in major urban markets ## ## Questions to inspire discussion.
Tesla’s Robotaxi Dominance.
🚗 Q: How significant could Tesla’s robotaxi business become? A: Tesla’s robotaxi business could represent around 90% of its enterprise value by 2029, capturing a substantial share of Ark’s projected $10 trillion global robotaxi market.
🏙️ Q: What’s the potential impact of robotaxis on urban transportation? A: Research suggests 200,000 robotaxis, supplemented by privately owned vehicles in an Airbnb-like model, could meet all of urban Austin’s vehicle miles traveled (VMT) demand, with peak demand requiring 350,000 vehicles.
Manufacturing and Cost Advantages.
🏭 Q: How does Tesla’s manufacturing capability compare to urban demand? A: Tesla’s Austin factory alone could produce more vehicles than urban Austin’s entire ride-hail fleet in approximately 9 days, showcasing its vertically integrated manufacturing advantage.
Magnets with Potential to Zap Tumors in a Flash
The slot-shaped aperture in the curved chain of magnets accommodates beams at different energies — a feature that would allow rapid switching among energies for more effective cancer treatment.

When the magnets arrived at Brookhaven, Katie Chen, a mechanical engineer, produced an architectural model of the assembly that Rob Karl, Adrian Timon, Travis Herbst, and Edward Dabrowski from the Mechanical Support Group used to properly align the magnets and bolt them to a supporting steel plate. To test that the magnets would accommodate the planned beam trajectories, the team transported the assembled array to the NASA Space Radiation Laboratory (NSRL), a facility that draws particles from the collider-accelerator complex supplying beams to Brookhaven Lab’s nuclear physics research facilities.
“This team tirelessly dedicated their time and expertise to completing the assembly and worked with exceptional dedication throughout Father’s Day weekend to help with these tests,” Mahler said.

Tesla’s NEW Model Y L and FSD 14 Rumors
Questions to inspire discussion.
Autonomy and FSD
🤖 Q: What is the biggest valuation upside for Tesla? A: Tesla’s autonomy roadmap is considered the biggest valuation upside, with the company’s robotaxi plans involving 5-passenger vehicles without a driver seat potentially increasing upside option values for investors.
🚘 Q: How has Tesla’s Full Self-Driving (FSD) system improved? A: FSD has made massive improvements with Version 13, and Version 14 may be the breakthrough moment that pushes Tesla past human-level driving and conquers another three nines of safety.
Future Projections.
📈 Q: What is the expected FSD take rate in the coming years? A: The FSD take rate is projected to increase to 20% in the next few years, with cyber cabs having FSD included, while individual owners may need to opt-in for a while before it becomes standard on all new cars.

Astronomers probe the nature of a massive young stellar object
Astronomers from Argentina and Spain have performed near-infrared observations of a massive young stellar object known as MYSO G29.862−0.0044. The observational campaign sheds more light on the nature of this object and its unique morphology. The new findings are presented in a paper published August 13 on the arXiv preprint server.
Massive young stellar objects (MYSOs) are stars in the very early stage of formation and the progenitors of massive main-sequence stars. However, due to their short formation timescale (about 10,000–100,000 years) and the severe extinction by the surrounding gas and dust, observations of MYSOs remain challenging.
Located some 20,200 light years away, MYSO G29.862−0.0044 (YSO-G29 for short), is a massive young stellar object associated with the star-forming region G29.96–0.02. The object is likely embedded within a dense molecular core.
Nanodroplets could speed up the search for new medicine
Until now, the early phase of drug discovery for the development of new therapeutics has been both cost- and time-intensive. Researchers at KIT (Karlsruhe Institute of Technology) have now developed a platform on which extremely miniaturized nanodroplets with a volume of only 200 nanoliters per droplet—comparable to a grain of sand—and containing only 300 cells per test can be arranged.
