Alleviating Traffic Congestion:

Elon Musk discusses the motivation behind his focus on boring tunnels under cities, primarily aimed at easing the “soul-destroying” problem of traffic congestion. He views traffic as a universally detrimental issue that robs people of their time, particularly in places like Los Angeles.

Key Features of 3D Tunnel Networks:

Musk presents the concept of a 3D tunnel network, explaining two crucial aspects. First, the entry and exit points must seamlessly integrate into the existing urban layout, achievable using elevators and only two parking spaces. Second, these tunnels should allow for speeds up to 200 kilometers per hour, reducing typical commute times drastically.

Unlimited Tunnel Levels:

He tackles concerns about the tunnels merely shifting congestion to a different plane. Musk argues that you can keep adding levels to the 3D tunnel network, providing virtually limitless relief from congestion. Unlike skyscrapers, which have a height limit, tunnels can go deeper indefinitely, effectively combating any level of congestion.

Addressing High Costs:

The traditionally high cost of tunneling is a common objection, but Musk suggests achieving a tenfold reduction in costs through innovation. For example, reducing the tunnel diameter can lower costs significantly since the tunneling cost scales with the cross-sectional area.

Continuous Tunneling:

Another innovation involves the boring machines themselves. Current machines work in a stop-and-start pattern, taking time off to reinforce the tunnel walls. Musk envisions a system where the machine continually tunnels and reinforces simultaneously, achieving up to a factor of eight improvement in efficiency.

Beating ‘Gary the Snail’:

Musk humorously introduces a metric for success: beating ‘Gary the Snail,’ a pet snail that currently moves 14 times faster than existing tunnel boring machines. The goal is to outpace Gary, symbolizing a monumental increase in tunneling efficiency and speed.

By combining these factors, Musk believes that he can revolutionize the way we think about urban transport and ultimately improve the quality of life for people living in congested areas.

3D Tunnel Networks:

Elon Musk discusses his idea for 3D tunnel networks as a solution to alleviate traffic congestion. He emphasizes the importance of integrating tunnel entrances and exits seamlessly into the city fabric. Musk mentions that the tunnels are designed for high speeds (200 km/h), providing rapid transit.

Flying Cars: Why Not?:

Musk addresses the question of why flying cars may not be the optimal solution for future cities. He states that flying cars would generate high noise levels and wind forces, creating anxiety-inducing scenarios for people on the ground.

Hyperloop and Tunnels:

Musk sees a possibility to incorporate Hyperloop technology into these underground tunnels. He mentions that the tunnel walls need to be good enough to resist water tables and that such tunnels would inherently be capable of holding a vacuum, a requirement for Hyperloop.

Cost of Tunneling:

One of the major challenges of tunneling is its cost, with the LA subway extension costing about a billion dollars per mile. Musk believes that by reducing the tunnel diameter and using continuous tunneling machines, the cost could be reduced by an order of magnitude.

Depth and Detection:

Musk indicates that there is no real limit to how deep or long these tunnels could be. He adds that if tunnels are dug below a certain depth, they become virtually undetectable, dismissing concerns about tunneling under residential areas.

Speed Goals:

Musk also talks about a ‘pusher car’ used in Hyperloop tests, optimistically stating that it might be able to exceed the speed of the world’s fastest bullet train in a 0.8-mile stretch.

Near Future Applications:

For high-density areas like the stretch between DC to New York, Musk suggests that going underground would be more practical. He assures that if the tunnel is deep enough, it would be undetectable, even with highly sensitive seismic instruments.

The Boring Company as a Hobby:

Elon Musk discusses the inception of The Boring Company, a venture he considers a “hobby.” Despite dedicating only 2-3% of his time to it, he mentions that the company is making good progress with interns and part-time workers using second-hand machinery.

Link between Tesla and Tunneling:

One of the motivations for tunneling, according to Musk, is to mitigate the potential increase in road congestion due to self-driving and electric cars. He points out that while autonomous cars may initially alleviate some congestion, shared autonomy will ultimately make car travel more affordable than public transport, resulting in more cars on the road and worsening traffic.

State of Electric Vehicle Adoption:

Musk notes that almost every automaker now has some form of an electric vehicle program. He perceives varying levels of commitment among these companies; some are serious about transitioning to electric vehicles, while others are merely “dabbling” in the technology.

Future of Tesla:

When asked if he could “declare victory” given the wider adoption of electric cars, Musk states his intention to remain with Tesla for the foreseeable future. He hints at exciting upcoming projects, including the Tesla Model 3 and the unveiling of a Tesla semi-truck.

Shared Autonomy and Traffic:

Musk elaborates on the concept of shared autonomy, stating that it could make individual car travel cheaper than taking a bus. This affordability, he argues, would result in an increase in the amount of driving and thereby make traffic conditions worse, despite the efficiency gains from autonomous technology.

Camera-based Autonomy:

Elon Musk emphasized Tesla’s focus on using passive optical systems, or cameras, for autonomous vehicle navigation. Unlike competitors that use LiDAR, Tesla believes solving vision through neural networks can render a vehicle “superhuman” in terms of navigation.

Upcoming Milestones:

Musk suggested Tesla vehicles could achieve a cross-country drive, from LA to New York, completely autonomously by the end of 2017. He said this flexibility wouldn’t be restricted to predefined routes; the vehicle should be able to change its destination dynamically.

Autonomy Safety:

Musk discussed the issue of safety, noting that the aim is not to achieve perfection but to be statistically safer than human drivers. He estimated that truly safe, hands-free autonomous driving is about two years away, and said the key is ensuring the technology is reliable enough to significantly mitigate the risk of crashes.

Shared Autonomy and Economic Models:

Musk envisions a future where a shared autonomy fleet would allow car owners to earn money by letting their cars serve others, similar to an Uber-like service. In such a scenario, the revenue generated could potentially even cover the cost of the car’s lease, making the car effectively “free” for the owner.

Data Collection and Adaptability:

Musk noted that the existing Tesla fleet is accumulating a vast amount of data on road conditions and scenarios, making the technology increasingly robust. He emphasized that the technology is probabilistic and is likely to at least mitigate crashes in most circumstances.

Industry Disruption:

Finally, Musk pointed out that once truly safe, hands-off autonomous driving is achieved, it would have the potential to massively disrupt the industry, not just in terms of vehicle sales but also by transforming the economics of car ownership and transportation services.

Teaser of Tesla Semi:

Elon Musk briefly mentioned the upcoming Tesla Semi-truck, although the details were scant. A teaser shot was provided, but Musk indicated caution regarding the autonomy features of the Semi. The vehicle is described as a heavy-duty, long-range truck aimed to revolutionize the industry’s perceptions of what electric trucks can do.

Power and Torque:

Musk emphasized that the Tesla Semi will outperform diesel trucks in terms of torque. He mentioned that the truck will have a flat torque RPM curve thanks to its electric motor, compared to the hilly curve of internal combustion engines. This feature will make the truck “spry,” capable of tugging a diesel semi uphill in a tug-of-war scenario.

Driving Experience:

The Tesla Semi is designed to offer a unique driving experience, described as “nimble” and comparable to driving a sports car. The truck will have a single-speed transmission, no gears, and will allow for rapid and agile maneuvers. Musk himself has test-driven a prototype, finding the experience “crazy” and “cool.”

Industry Disruption:

Musk highlighted that the Tesla Semi aims to disrupt industry norms about electric trucks, particularly concerning power and range. The truck is being designed to alleviate heavy-duty trucking loads and demonstrate that electric trucks can indeed be as efficient, if not more so, than their diesel counterparts.

Not Vaporware:

The fact that a prototype of the Tesla Semi has already been test-driven by Musk indicates that this is a tangible project in development, rather than speculative technology or “vaporware.” It also signals Tesla’s commitment to innovation in the heavy-duty trucking space.

By discussing both the Semi’s advanced capabilities and the practical experience of driving a prototype, Musk paints a compelling picture of how Tesla aims to revolutionize the trucking industry.

Solar Roofs as the Future:

Elon Musk envisions a future where houses have solar roofs and electric cars in the driveway. Musk goes a step further to describe that the area between the house and the electric car may have “power walls,” essentially Tesla’s energy storage units, stacked alongside the home. The roof tiles themselves are specialized to be solar glass tiles that can generate electricity.

Technical Aspects of Solar Roofs:

Musk elaborates on the advanced technology behind the solar glass tiles. They contain micro louvers to maintain an even appearance from street level. This way, solar and non-solar tiles look the same, offering aesthetic uniformity. From a higher viewpoint like a helicopter, the solar cells behind some tiles would be visible.

Cost-effectiveness and Durability:

When questioned about affordability, Musk is confident that the combination of the solar glass roof’s cost and the electricity it generates will be economically favorable compared to a regular roof plus electricity costs. He even joked about offering an ‘infinity’ warranty, emphasizing the durability of the glass tiles, which would outlast the house itself.

Rollout and Scale of Ambition:

Musk indicates that two types of these solar roofs will be introduced first, followed by two more types in the subsequent year. His ambition for the scale of this technology is vast, foreseeing a future where almost every house will have a solar roof. However, he acknowledges that this transition will likely occur over a period of 40-50 years.

Energy Self-sufficiency and Economics:

Musk agrees with the notion that most houses in the U.S. have sufficient roof area to generate all their energy needs, depending on the house size and location. The falling price of lithium-ion batteries, a key component in Tesla’s cars and energy storage solutions, is mentioned as the economic linchpin for this vision.

Through this discussion, Elon Musk outlines a comprehensive and sustainable future for residential energy, emphasizing the technological advancements, cost-effectiveness, and long-term durability of solar roofs.

Gigafactory’s Role and Scale:

Elon Musk elaborates on Tesla’s Gigafactory, a pivotal part of the company’s plan to scale up battery production. The factory, shaped like a diamond and aligned to TrueNorth, has an eventual output goal of 100 gigawatt-hours of batteries per year. This large-scale production is central to Tesla’s aim of reducing the cost of lithium-ion batteries and by extension, electric vehicles and home energy systems.

Production Speed:

Musk confirms that the Gigafactory is already in production. When asked about the production speed of the cells in a shared video, Musk reveals that it’s so fast that the cells appear as a blur when running at full speed. This indicates an incredibly high throughput for battery cell manufacturing.

Energy Guilt and Global Impact:

Musk discusses his broader vision of an exciting future where people “no longer feel guilty about energy.” He estimates that around 100 Gigafactories are needed globally to transition away from fossil fuels. This projection provides a tangible framework for envisioning global energy sustainability.

Future Gigafactories:

Musk hints that Tesla plans to announce locations for two to four more Gigafactories within the year. When pressed for specifics on locations, he mentions the necessity to address a global market, implying international expansion.

Advisory Role in Politics:

When questioned about his role in advisory councils, particularly under a leader skeptical about climate change, Musk outlines the limited extent of his contributions. He mentions that these meetings have given him the platform to argue in favor of climate change action and immigration. Despite the uncertainty of the outcome, he believes in the importance of having such viewpoints expressed in these settings.

Overall, Musk shares an insightful outlook on Tesla’s role in energy sustainability, detailing the crucial function of Gigafactories, plans for future expansion, and his stance on using advisory roles to advocate for environmental issues.
