Researchers at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) have created the most efficient solar cell recorded yet – a 39.5% efficiency under normal sunlight illumination – which is 0.3% higher than the record they set in 2020. These small incremental gains show how difficult it is to increase efficiency, but it […]
Whenever the Israel topic comes up, we try to tread lightly. As famed American philosopher Louis C.K. once said, “Jew” is the only word that can be derogatory or descriptive, just based on tonal inflections. Most people’s knowledge of Jews probably extends to the funny-looking people seen walking around New York airports. Those are Hasidic […]
A surprisingly large number of retail investors ask Google which stock is the best to own. The response is about as predictable as asking the barber if you need a haircut. Any number of pundits out there will tell you which stocks they think you ought to buy. What most lack is a methodology to […]
A good idea and $4.50 won’t get you a gallon of petrol in the U.S. these days. The ability to execute is what separates wantrepreneurs from entrepreneurs. And of course, a willingness to expend every iota of your time and energy trying to build a business in the face of a dismal failure rate. Similarly, […]
If Warren Buffett is the Oracle of Omaha, then Elon Musk is the Mystic of Moonshot Technologies. We’re no fanboys of the Tesla (TSLA) and SpaceX CEO, but we give the man his due in spite of his occasional impersonation of the Mayhem guy in the Allstate commercials. While most of the focus is on […]
The idea of a solar-powered flashlight was supposed to be a joke until it wasn’t. In many emerging markets you’ll find cheap little solar-powered lamps that sit in the sun all day charging, then provide light at night. Not everyone has access to a store that sells batteries, so it’s a solution to a problem. […]
If you’re someone who drives a rig that gets 10 miles per gallon, here’s how you can hedge the increasing costs at the pump. Invest in two dividend champions whose ebb and flow are tied directly to the price of oil – Exxon Mobil (XOM) and Chevron (CVX). Exxon has a fascinating business model with […]
The emergence of special purpose acquisition companies (SPACs) has paved the way for financiers to make boatloads of cash very quickly, companies to raise massive amounts of funding very quickly, all while the retail investor gets the short end of the stick. We’ve covered more than 40 SPACs, and what they all have in common […]
Solar is finally having its day in the sun as the Invesco Solar ETF reaches new highs, aided by the merger of Sunrun and Vivint which have soared to the moon. The reason? Everything points to solar being the theme du jour for Robinhood day-trader types to pile into. Further evidence to support this claim […]
Why Has the Guggenheim Solar ETF (TAN) Underperformed? was the title of an article we published more than three years ago. My how things have changed. Since the beginning of this year, TAN is up +96% compared to a Nasdaq return of +24% over the same time frame. There’s no longer any competing solar ETF […]
