The potential impact of electric vehicles on global energy systems
Posted by Bill Kemp in categories: energy, transportation
Electric vehicles are unlikely to create a power-demand crisis but could reshape the load curve. Here’s how to bend that curve to your advantage.
Could electric vehicles (EVs) soon face a different kind of gridlock? With the electrification of mobility accelerating, energy producers and distributors need to understand the potential impact of EVs on electricity demand (Exhibit 1). The good news: McKinsey analysis suggests the projected growth in e-mobility will not drive substantial increases in total electrical-grid power demand in the near to midterm, thus limiting the need for new electricity-generation capacity during that period.

Uncertain human consequences in asteroid risk analysis and the global catastrophe threshold
Posted by Alexei Turchin in categories: asteroid/comet impacts, biotech/medical, existential risks, policy
By pure coincidence, the article by Seth Baum was published just 5 days after a small asteroid exploded over early warning Tule station in Greenland.
This paper studies the risk of collision between asteroids and Earth. It focuses on uncertainty in the human consequences of asteroid collisions, with emphasis on the possibility of global catastrophe to human civilization. A detailed survey of the asteroid risk literature shows that while human consequences are recognized as a major point of uncertainty, the studies focus mainly on physical and environmental dimensions of the risk. Some potential human consequences are omitted entirely, such as the possibility of asteroid explosions inadvertently causing nuclear war. Other human consequences are modeled with varying degrees of detail. Direct medical effects are relatively well-characterized, while human consequences of global environmental effects are more uncertain. The latter are evaluated mainly in terms of a global catastrophe threshold, but such a threshold is deeply uncertain and may not even exist. To handle threshold uncertainty in asteroid policy, this paper adapts the concept of policy boundaries from literature on anthropogenic global environmental change (i.e., planetary boundaries). The paper proposes policy boundaries of 100 m asteroid diameter for global environmental effects and 1 m for inadvertent nuclear war. Other policy implications include a more aggressive asteroid risk mitigation policy and measures to avoid inadvertent nuclear war. The paper argues that for rare events like large asteroid collisions, the absence of robust data means that a wide range of possible human consequences should be considered. This implies humility for risk analysis and erring on the side of caution in policy.

Tesla’s production problems extend to its solar roof business, too
Posted by Bill Kemp in categories: business, Elon Musk, energy, sustainability, transportation
The production problems Tesla has faced with its Model 3 have been well documented. Now, sources say the company is facing similar issues with its solar roof tile initiative. According to Reuters, former and current employees have revealed that assembly line problems, plus CEO Elon Musk’s exacting aesthetic demands, has delayed production, causing tension with partner Panasonic, and rattling officials that are keen to see a return on significant state investment.
The “Solar Roof,” produced at Tesla’s factory in Buffalo, New York, is designed to look like and function as a regular roof while also generating energy. According to sources, technical challenges have delayed production, as has Musk’s design plans. Speaking to Reuters, one source said that “Aesthetic look is the key point that Elon is not always satisfied with. That’s the big issue.”
Neither Tesla nor Reuters’ sources have revealed current production figures for the roof tiles, but the delays are such that Panasonic — which the initiative depends on for solar components — has been forced to find other buyers for the parts it had built to sell to Tesla. According to a former Panasonic employee, the company has been shipping “large volumes” of its photovoltaic cells as samples to other prospective buyers, due to low demand from Tesla. Panasonic declined to comment on the issue, stating only that it “believes Tesla will use Panasonic cells when it mass-markets the Solar roof.”

New laser based on unusual physics phenomenon could improve telecommunications, computing
Posted by Klaus Baldauf in categories: computing, engineering, physics
Researchers at the University of California San Diego have demonstrated the world’s first laser based on an unconventional wave physics phenomenon called bound states in the continuum. The technology could revolutionize the development of surface lasers, making them more compact and energy-efficient for communications and computing applications. The new BIC lasers could also be developed as high-power lasers for industrial and defense applications.
“Lasers are ubiquitous in the present day world, from simple everyday laser pointers to complex laser interferometers used to detect gravitational waves. Our current research will impact many areas of laser applications,” said Ashok Kodigala, an electrical engineering Ph.D. student at UC San Diego and first author of the study.
“Because they are unconventional, BIC lasers offer unique and unprecedented properties that haven’t yet been realized with existing laser technologies,” said Boubacar Kanté, electrical engineering professor at the UC San Diego Jacobs School of Engineering who led the research.

Samumed in $438 Million Deal to Develop Anti-agingTherapies
Posted by Steve Hill in categories: biotech/medical, life extension
Today, we were pleased to hear that Samumed, a San Diego-based biotech company working on regenerative medicine, has just raised $438 million towards developing anti-aging therapies.
SAN DIEGO – August 6, 2018 – Samumed, LLC, announced today that it has closed its A-6 Round of equity issuance with $438 million, bringing its total equity raised to date to more than $650 million. The pre-money valuation for the round was $12 billion.
“We appreciate the strong support from our investors,” said Osman Kibar, Ph.D., Chief Executive Officer of Samumed, “and we are now in a fortunate position to both move our later stage programs to commercialization, as well as expand on our earlier stage science and clinical portfolio.”

Chip Lights Up Optical Neural Network Demo
Posted by Klaus Baldauf in category: robotics/AI
Researchers at the National Institute of Standards and Technology (NIST) have made a silicon chip that distributes optical signals precisely across a miniature brain-like grid, showcasing a potential new design for neural networks.
The human brain has billions of neurons (nerve cells), each with thousands of connections to other neurons. Many computing research projects aim to emulate the brain by creating circuits of artificial neural networks. But conventional electronics, including the electrical wiring of semiconductor circuits, often impedes the extremely complex routing required for useful neural networks.
The NIST team proposes to use light instead of electricity as a signaling medium. Neural networks already have demonstrated remarkable power in solving complex problems, including rapid pattern recognition and data analysis. The use of light would eliminate interference due to electrical charge, and the signals would travel faster and farther.
