Research finds silicon-based, tandem photovoltaic modules can compete in solar market

New solar energy research from Arizona State University demonstrates that silicon-based, tandem photovoltaic modules, which convert sunlight to electricity with higher efficiency than present modules, will become increasingly attractive in the U.S.

A paper that explores the vs. enhanced efficiency of a new solar technology, titled “Techno-economic viability of silicon-based, tandem modules in the United States,” appears in Nature Energy this week. The paper is authored by ASU Fulton Schools of Engineering, Assistant Research Professor Zhengshan J. Yu, Graduate Student Joe V. Carpenter and Assistant Professor Zachary Holman.

The Department of Energy’s SunShot Initiative was launched in 2011 with a goal of making solar cost-competitive with conventional energy sources by 2020. The program attained its goal of $0.06 per kilowatt-hour three years early and a new target of $0.03 per kilowatt-hour by 2030 has been set. Increasing the efficiency of photovoltaic modules is one route to reducing the cost of the solar electricity to this new target. If reached, the goal is expected to triple the amount of solar installed in the U.S. in 2030 compared to the business-as-usual scenario.

Tesla, others help Puerto Ricans go solar amid power turmoil

Ten months after Hurricane Maria, Adjuntas still loses power any time a heavy rain or wind pounds the rickety power lines feeding this town high in the central mountains of Puerto Rico.

That leaves its 20,000 people once again in the dark, without light, fresh water or air conditioning—except for a handful of homes and businesses glowing in the night thanks to .

The people of Adjuntas call those places “cucubanos,” an indigenous Puerto Rican firefly. They’re part of a small but growing movement to provide the U.S. territory with sustainable, renewable energy independent of the decrepit grid.

What Are The New Jobs In A Human + Machine World?

Interesting article on the limited future of human paid employment for AI, some thoughts.


By Paul R. Daugherty and H. James Wilson

Superman versus Batman. Captain America versus Iron Man. Zuckerberg versus Musk?

The reported clash between the two technology titans is proof that not everyone sees the benefits and dangers of artificial intelligence in the same light. Yet from Facebook’s algorithms to Tesla’s self-driving cars, it’s clear that AI isn’t science fiction any longer—and that we’re already at the cusp of a new era, with AI poised to deliver transformational change in business and society.

Celebrating Success at Our First Conference

We brought the leading experts in aging research and biotech investment together for an action-packed day of science. See what happened at this exciting event and check out our first event video now.


On July 12th, we hosted our first conference, Ending Age-Related Diseases: Investment Prospects & Advances in Research, at the Frederick P. Rose Auditorium, which is part of the Cooper Union campus in New York City. We are delighted to announce that the conference was a huge success with 160 attendees, a wide variety of speakers from both research and business, and some great discussion panels.

The goal of this conference was to promote multidisciplinary collaboration in order to foster the development of next-generation drugs and therapies that directly target the processes of aging and thus have the potential to prevent and cure age-related diseases.

For those of you who could not join us there, we have recorded the talks and panels from the conference, and we will be making them available on our website in the next few weeks once we have edited them. As a special thank you, the Lifespan Heroes, our monthly patrons, will be offered early access to these videos ahead of a public release.

The market for alternative-protein products

Here, the problem is marketing. Around 2bn people eat insects already, but few of them are Westerners. Changing that could be a hard sell. Grind the bugs up and use them as ingredients, though, and your customers might find them more palatable. Hargol FoodTech, an Israeli startup, plans to do just that. Locust burgers, anybody?


MOST people like to eat meat. As they grow richer they eat more of it. For individuals, that is good. Meat is nutritious. In particular, it packs much more protein per kilogram than plants do. But animals have to eat plants to put on weight—so much so that feeding livestock accounts for about a third of harvested grain. Farm animals consume 8% of the world’s water supply, too. And they produce around 15% of unnatural greenhouse-gas emissions. More farm animals, then, could mean more environmental trouble.

Some consumers, particularly in the rich West, get this. And that has created a business opportunity. Though unwilling to go the whole hog, as it were, and adopt a vegetarian approach to diet, they are keen on food that looks and tastes as if it has come from farm animals, but hasn’t.

Too healthy for your own good?

Why on Earth would you ever want to be less than completely healthy?


Recently, Reason of Fight Aging! pointed out psychological research revealing a certain conservatism in terms of what people consider to be the “ideal” levels of happiness, intelligence, longevity, and even health.

It probably doesn’t come as a surprise that significant numbers of people in the studies weren’t too keen on the idea of living much longer than the average (around 90 years), and even under the assumption of eternal youth, their preference didn’t go past 120 on average; after all, LEAF wouldn’t be in business if the idea of healthy life extension wasn’t so inexplicably frowned upon. What’s really flabbergasting, though, is that even health—health!—is apparently something you can have too much of; on a scale from 0 (“completely unhealthy”) to 100 (“completely healthy”), the average preference gravitated somewhere between 80 and 90. These results provide us with an occasion for reflection.

(Il)logical conclusions

It’s uncertain whether the respondents in these studies realized the bizarre yet inevitable implications of their statements. If 100 means “completely healthy” and your “ideal” level of health is only, say, 85, does that mean that, should you ever perceive that you’re about “90” healthy, you’d deliberately start looking into ways of harming your own health to get back to your ideal level? How, exactly, would being “90” healthy be too much? What would you dislike about not being a little more sick? How would you benefit from being less than completely healthy? Has there ever been, at any point in your life, a moment when you thought, “Blimey, I’m far too healthy for my own good. Time to get sick”? Do you think a point will ever come when, while sick, you’ll think, “Perfect timing—I was just concerned that I was healthier than my ideal level”?

Germany’s Bayer closes $63 billion Monsanto takeover, plans to drop US company’s name

Monsanto’s agricultural biotechnology research and development operations that are going to Bayer are the largest in the world and include making genetically modified seeds for such crops as corn, soybeans and cotton. Corn represented almost 60 percent of Monsanto’s total seed and genomics business last year.


German conglomerate Bayer on Thursday closed its $63 billion merger with St. Louis-based agribusiness giant Monsanto and plans to drop the U.S. company’s name.
