How the Science of Decision-Making Will Help Us Make Better Strategic Choices
Posted by Shailesh Prasad in categories: energy, information science, science
Neuroscientist Brie Linkenhoker believes that leaders must be better prepared for future strategic challenges by continually broadening their worldviews.
As the director of Worldview Stanford, Brie and her team produce multimedia content and immersive learning experiences to make academic research and insights accessible and useable by curious leaders. These future-focused topics are designed to help curious leaders understand the forces shaping the future.

Proof-of-Work Alternatives: Massive electric consumption by cryptocurrency mining
Posted by Philip Raymond in categories: bitcoin, cryptocurrencies, economics, energy, environmental
Some blogs and news outlets eschew long titles. Publishers want readers to scan a list of topics that fit on one-line each. But, a better title for this article would be:
“Massive electric consumption by cryptocurrency mining:
An unfortunate environmental nightmare will soon pass!
… Proof-of-Work alternatives are on the horizon”
A considerable amount of electricity is used in the process of mining Bitcoin and other cryptocurrencies. Miners are effectively distributed bookkeepers, and this use of resources is part of a system called “proof-of-work”. It keeps the books fair, honest, and without an ability for the miners to collude (In other words, they cannot ‘cook the books’).

Scientists think they’ve discovered a fourth type of fuel for humans — beyond carbs, fat, or protein
Posted by Shailesh Prasad in categories: energy, food
- Ketones could super-charge the body in a way that’s unlike any other source of fuel.
- San Francisco-based startup HVMN recently launched a drink made of pure ketone ester to harness its performance-boosting qualities.
- The company partnered with Oxford University to leverage $60 million-worth of scientific research on elite athletes.
The nutrition label on a shot-sized bottle of this clear, odorless liquid defies traditional explanation. It contains 120 calories — roughly the equivalent of a hearty slice of bread — yet it has no fat, no protein, and no carbohydrates.
Those calories instead come from ketones, an ingredient that Geoff Woo, cofounder and CEO of San Francisco-based human performance startup called HVMN (pronounced “human”)to call “the fourth macronutrient.”

Scientists Develop Fossil-Fuel-Based Technology That Consumes Carbon Dioxide

Engineers at The Ohio State University are developing technologies that have the potential to economically convert fossil fuels and biomass into useful products including electricity without emitting carbon dioxide to the atmosphere.
In the first of two papers published in the journal Energy & Environmental Science, the engineers report that they’ve devised a process that transforms shale gas into products such as methanol and gasoline—all while consuming carbon dioxide. This process can also be applied to coal and biomass to produce useful products.

Record-breaking hybrid drone stays aloft for over four hours
Posted by Genevieve Klien in categories: drones, energy
Drone technology is getting better all the time, and one area folks are putting a lot of energy into is boosting the amount of time the things can stay in the air. Drone manufacturer Quaternium is claiming a new milestone in this field, after flying its HYBRiX.20 fuel-electric quadcopter for four hours and forty minutes in what it describes as a world record flight for a self-powered multicopter.
Most multicopter drones you can buy off the shelf boast flight times of 25 to 30 minutes, though we have seen custom-built multicopters fly for far longer. Last year, for example, a commercial drone operator used a bespoke quadcopter to cross the English channel in a 72-minute jaunt, while others such as dronemaker Skyfront have previously claimed endurance records well in excess of four hours.
