Instead of Trump's Wall, Let's Build a Border of Solar Panels | Anthropocene
Donald Trump has repeatedly called for Mexico to build a wall between our countries. There is indeed a way that Mexico could create a barrier between the US and Mexico, one constructed exclusively on the Mexican side, with substantial benefits for both countries and the planet: a solar border.

Sunlight in the northern deserts of Mexico is more intense than in the US Southwest because of the lower latitude and more favorable cloud patterns. And construction and maintenance costs for solar plants in Mexico are substantially lower. Thus, building a long series of such plants all along the Mexican side of the border could power cities on both sides faster and more cheaply than similar arrays built north of the border.

Solar energy is already being generated at lower prices than those of coal. With solar plants along vast stretches of the almost 2,000-mile US-Mexico border on the Mexican side, a new high-voltage direct-current (HVDC) grid could be set up to transmit energy efficiently from that long, snaking array to population centers along the border. HVDC power lines lose exponentially less energy over long distances than traditional power lines. Cities that could immediately benefit include San Diego, Tijuana, Mexicali, Tucson, Phoenix, El Paso, Ciudad Juarez, San Antonio, and Monterrey.

smiley I would like to add to that idea... Build that wall! DO line it with solar panels that will provide power to light the wall , recharge the electric drones / killer robots, and charge the battery banks for the 200KV electric shocking grid wire. Good thinking Gemini! smiley

What an excellent idea.

The reason for having the wall on the Mexican side:

"lower latitude and more favorable cloud patterns"
doesn't quite make sense to me though. Why not both sides?

If the wall is on the border of the U.S. and Mexico,
The latitude would be the same at any given point along that line.
Elevation would be the same on the US or Mex side of the actual border.

And the cloud patterns? What appreciable variance in patterns would there be at any given point on this border wall?

A cloud formation doesn't just disappear or go through transformative gyrations the minute it crosses the aerial border into the U.S.
Indirectly referring to smog, reduced air quality on the US side?
The entire US should have converted to solar long ago. a great many problems would have been averted...
including the discord we are experiencing so profoundly right now. Just think, energy... free. Boggles the mind.
PG&E jobs switched over to the processing, production, installation and maintenance of the wall grid.
