There is no need to physically attach solar panels to your car’s roof to determine if it will charge your car. Of course it will while it’s in the sun. Let’s do some math:
If:
The area of this Tesla’s roof is 2 square meters (being generous),
The efficiency of the panels is 25%,
The capacity factor of solar (depending on your location) is 20%,
The sun’s irradiance is 1000 watts per square meter,
The Tesla’s battery capacity is 100 KWhrs,
And we neglect the increased weight and drag of the array,
We’re talking about 100 hours, more than 4 days.
Doesn’t sound like a bargain, especially considering that if you overbuild the solar array on your roof and charge your car in your garage, you’ve achieved the same goal at far less expense and inconvenience.
If the corruptive influence of Big Oil can somehow, someday, be removed from the economics of energy and transportation, renewables will become the deal of the century, almost overnight.
Accepting the fact that the Trump administration of completely dedicated to the fossil fuel industry as its main source of donations, we need to hope to that the majority of humankind votes with its wallet in the direction of the survival of the planet.
As shown in This stands to reason, since the rest of the world is not criminally insane, nor hellbent on keeping Trump in office so that he might stay out of prison.
If we still have an organized human civilization here in 50 years, people will still be scratching their heads, wondering how a man who attempted to overthrow the United States federal government a) escaped criminal prosecution and b) was subsequently re-elected to the U.S. presidency.
IMO, the founding fathers did everything they could have conceivably done to prevent the complete breakdown of the nation, but they never considered that the American people could be so stupid.
It wouldn’t surprise me if one of the framers of the Constitution said to another, “If this country falls apart because it elects a criminal lunatic, they will deserve exactly what they got.”
