Old Reno & The Promise Of New Reno. How Is Tesla Gigafactory Shifting Nevada?

Posted by in categories: business, sustainability

Forget the latest Hollywood film noir and spend some time learning about this story instead. The story is that of Reno, Nevada, and the location of the original Tesla Gigafactory. The historical drama, a true story, unfolds with twisting and dark details.

The story came to light due to the notable new podcast series The City (USA Today’s investigative podcast). Episode 4 of season 2 is titled “West World.”

Bacteria farms produce natural sugar safe for diabetics and teeth

Posted by in categories: biotech/medical, food, health, sustainability

Sugar poses one of the most pressing health problems in the modern world – not least because it’s just so delicious. Rather than quitting sweets cold turkey, low-calorie alternatives to sucrose could make tasty treats that are at least less bad for us. And now, researchers from Tufts University have developed a more efficient method for producing one such sweetener, using farms of bacteria.

The sugar in question is called tagatose, which the FDA says is “generally regarded as safe.” It’s 92 percent as sweet as sucrose – regular old table sugar – but because the human digestive system doesn’t metabolize as much of it, it only has 38 percent of the calories. That, in turn, means tagatose has a much smaller effect on blood glucose and insulin, making it safe for diabetics. And to cap it off, tests show that it doesn’t contribute to cavities or tooth decay.

But, of course, there’s a catch – tagatose is a little complicated to produce. Normally, it’s done by hydrolyzing lactose to make galactose, which is then isomerized into tagatose, which then needs to be purified and crystallized into a solid, usable form. Yields from this process are low, at less than 30 percent.

New hybrid device can both capture and store solar energy

Posted by in categories: solar power, sustainability

Researchers from the University of Houston have reported a new device that can both efficiently capture solar energy and store it until it is needed, offering promise for applications ranging from power generation to distillation and desalination.

Unlike and , which rely on photovoltaic technology for the direct generation of electricity, the hybrid device captures heat from the sun and stores it as . It addresses some of the issues that have stalled wider-scale adoption of solar power, suggesting an avenue for using around-the-clock, despite limited sunlight hours, cloudy days and other constraints.

The work, described in a paper published Wednesday in Joule, combines molecular energy and latent heat storage to produce an integrated harvesting and for potential 24/7 operation. The researchers report a harvesting efficiency of 73% at small-scale operation and as high as 90% at large-scale operation.

Bill Gates-backed solar startup announces major breakthrough

Posted by in categories: solar power, sustainability

Heliogen is a startup that wants to “replace fuels with sunlight.” And the Bill Gates-backed solar startup, which has flown under the radar until today, has made a major green-energy breakthrough for heavy industry. Heliogen “has created the world’s first technology that can commercially replace fuels with carbon-free, ultra-high temperature heat from the sun.”

The Anti-Solar Panel — A Device That Generates Electricity From Darkness

Posted by in categories: solar power, sustainability

There are different kinds of solar panels. The one most typically used is a type that generates electricity from the sun through a physical process called the photo-voltaic (PV) effect – when light exposure on certain materials generates an electric current. Another type generates electricity from heat through thermal processes – when the sun is hotter and Earth is cooler, and the difference in temperature can be converted into usable energy.

That second kind of solar panel is the one that inspired a team of researchers at Stanford University in Palo Alto, California to develop a new system that can harness energy in darkness. It’s based on the concept of using heat to generate energy but an inverse version of the solar panel. While the solar panel uses the heat difference between the sun and Earth with the Earth being the cooler side – their system makes use of the heat difference between the coolness of the night atmosphere and the Earth with the Earth being the hotter side. The study has been published in the scientific journal Joule.

Study author Shanhui Fan, Stanford electrical engineering professor, told Gizmodo:
