A creative Tesla owner recently took sustainability into his own hands by installing a solar roof on his Model 3, testing whether it could generate enough energy to charge the electric vehicle independently—and it worked. The modification integrates solar panels seamlessly onto the car’s roof, capturing sunlight and converting it into electricity to supplement or even fully power the vehicle’s battery.

I saw a Prius with PV roof at a car show in 2009 when I first got interested EVs. They look cool, and if that’s important to you, please be my guest.

The reason they are a rarity though is math and physics. At most places on the planet, Earth receives about 1000 Watts/square meter. Assuming 8 hours per day of high-grade sunshine, 3.5 square meters of PV, an efficiency of 25%, that’s 250 Watthours/day. This translates to about one mile per day for the typical EV.

If you want to fully power your 100 KWhr Tesla, that’s 400 days, just over a year–not too compelling.

Celebrating American Ignorance

Published

There are so many tragic aspects to life in today’s United States that it’s hard to name them all.

For my money, one of the saddest elements to the American zeitgeist is its glorification of ignorance.

Up until recently, if you wanted to know what science believes about anthropology, climate change, or particle physics, you asked a scientist in the relevant discipline, who not only has a college degree, but normally a ton of education on top of that.

Now, you ask a congressional Republican, preferably, an evangelical Christian.

How and Why We Conduct Science

To the author of the meme here (if it’s an actual human being, vs. a Russian bot): to the best of my knowledge, the only actual major “scientific fraud” in world history was “Piltdown Man.”  In 1912, a pseudo-anthropologist attempted to fool the scientific community into believing he had discovered the “missing link” between apes and humans.

Now, are there examples of instances when the science of the day turned out to be incorrect?

Of course, and new instances of this surface every day.

Think of how little when scientists believed 200 years ago is still intact today.  Perhaps most obviously, Newtonian mechanics has fallen to relativity and quantum physics, but there are hundreds of other paradigm shifts in health and medicine, psychology, cellular biology, chemistry, and particle physics.

Contrary to what conspiracy theorists want you to believe, science is not a set of facts; it’s a methodology whereby we come to learn more about ourselves and the world around us.

Are there other methods by which we “learn?”  Sure.  Some uneducated guy goes on YouTube and becomes convinced that our consumption of fossil fuels is not causing the temperature of the Earth’s atmosphere and oceans to rise.  I would argue that this conduct is inferior to the scientific method.

Trump is not an idiot.  His IQ may not be too high, but he’s smart enough to know how to conduct himself in his lifelong quest to amass more wealth and power at the expense of everyone else on Earth.
