A reader wants to raise many millions of dollars to develop the technology described in this presentation, claiming that it’s a breakthrough in generating energy from the sun without using PV or CSP. I respond:
Sorry, but this makes no sense. Will it generate a large force/pressure? Yes. Will it generate large amounts of energy? No. Energy is the integral of force over a distance, and this device will do very little of that. (more…)
Over the years here at 2GreenEnergy, I’ve pointed our readers to several explanations of climate change that I thought were particularly on point. But it wasn’t until yesterday that I came across this masterpiece: “13 Misconceptions About Climate Change,” which, as its title suggests, refutes each of a baker’s dozen arguments commonly propounded by climate deniers, in the form of a discussion between a man of science and his alter-ego. Not only is this clever beyond belief, it’s incredibly accessible to a non-scientific audience. (more…)
What will our energy future look like? What guidelines should be given to the production and distribution of energy tomorrow? These questions are the source of numerous heated debates in society and politics. The task of an energy company is to ensure energy supply and to bring new ideas to meet the different needs. (Note: unfortunately, energy companies, at least here in the US, are not tasked to bring new ideas. –ed) (more…)
This article on waste-to-energy is a reminder that there are areas of technology that seem to attract people who have no compunction about exaggerating their claims, among which is WTE. Of course, this is easily understood, as this discipline has so many moving parts. Unlike, e.g., solar, wind, hydro and geothermal, WTE is not a black and white subject. (more…)
It’s the birthday of W.S. Gilbert (pictured), who, with musical partner Sullivan, wrote some wonderful comic operas of the late 19th Century, including H.M.S. Pinafore (1878), The Pirates of Penzance (1879), and The Mikado (1885).
I bring this up to show how greatly our society has changed (fallen?). To gauge this, I ask you listen to my very favorite piece of theirs, and ask yourself how this would be regarded by our pop culture today.
Not only have we changed in so many important ways, but the rate of change continues to increase; more of our world has changed in the last 10 years than it had in the previous 50. It’s scary stuff, insofar as it appears that our civilization is in chaos, spinning wildly out of control. But perhaps this is part of a progression towards higher goals, like a sustainable approach to life on this planet. Could be.
For some reason I’ve been running across a spate of humorous and terrifically well done pieces that make important points. Here’s one on climate change deniers that got me laughing so loudly that I’m sure the people outside my office here thought I must be having some sort of mental breakdown.
We think that our scientists take an attitude to all this that is, well, scientific. Here’s what happens when frustration builds up and one of them has a guitar.
Enjoy.
Driving is not as expensive as it has traditionally been in recent years, largely because gas prices– one of the largest day-to-day expenses with driving– have been low. While over 200,000 oil workers have lost their jobs, many consumers have been celebrating the cut in price.
For simplicity, gas prices are usually measured by the price of a barrel of oil. To put the situation into perspective, by October 2015, the price of a barrel of oil had been cut by about half since June 2014. This represented price levels not seen since the 2009 recession. (more…)
(Note: Calling a car with a 608 HP 8-cylinder engine “eco-friendly” is REALLY misusing the phrase, but whatever; I let guest bloggers say pretty much what they want. -ed)
Luxury cars are in trend right now, and it looks like major car manufacturers have already started focusing more on eco-friendly engines. From Rolls Royce to BMW, every famous brand seems to have thought of a hybrid for their line of exclusive vehicles. Porsche has recently joined the group, too. The company’s latest 918 Spyder is a hybrid supercar.
If readers see 2GreenEnergy popping up with increasing frequency on social media, that’s not an accident. My friend and colleague Brian Bernhard of Blight Productions has been helping us become more active on Facebook, Twitter, and LinkedIn, as well as Instagram and all these new platforms that are so popular among young people.

I love media that makes its point in a fun, appealing way. This piece on climate change by cartoonist Mark Fiore is a work of art.
Note the naiveté of the little green man, and compare that to the guy asking Robin Williams about the invention of golf in this classic (pardon the foul language).
