Video: Spain's Stunning Solar Towers Video: Spain's Solar Thermal Towers

Watch this video to see the future of large-scale, carbon-free electricity production.


Concentrated solar power—aka solar thermal, aka the "other solar"—will be a core element of the transition from dirty coal to clean energy. The advantage of coal plants is that they produce a steady, predictable amount of electricity for a relatively cheap cost. Concentrated solar has the potential to do that. A while back, I devoted a post to the basics of the technology. In that piece, I highlighted a CSP plant near Seville, Spain, that, at the time, was the world's largest:

Today's CSP projects aim to generate power on an industrial scale, creating a baseload electricity supply that could potentially replace large, centralized fossil fuel-burning plants. Just this week, the world's largest (but not for long) CSP operation plugged in-the PS20 plant in Seville, Spain trains 1,255 mirrors on a 531-foot tall water-filled tower. The intense heat boils the water, which creates steam. The steam spins a turbine, and-voila!-electricity is generated. Under optimum conditions, the plant can churn out 20 megawatts of juice, enough to power 10,000 homes.

The Guardian just posted a great video about that plant's predecessor, the PS10, which was the world's first commercial CSP project. It's a smart look at the future of large-scale carbon-free energy production, and digs into some of the economic challenges as well.

If you are totally ready to move on from Donald Trump, you're not alone. According to a report last April from the Wason Center National Survey of 2020 Voters, "President Trump will be the least popular president to run for reelection in the history of polling."

Yes, you read that right, "history of polling."

After three years on the sidelines, Colin Kapernick will be working out for multiple NFL teams on Saturday, November 16 at the Atlanta Falcons facility.

The former 49er quarterback who inflamed the culture wars by peacefully protesting against social injustice during the national anthem made the announcement on Twitter Tuesday.

Kaepernick is scheduled for a 15-minute on-field workout and an interview that will be recorded and sent to all 32 teams. The Miami Dolphins, Dallas Cowboys, and Detroit Lions are expected to have representatives in attendance.

"We like our quarterback situation right now," Miami head coach, Brian Flores said. "We're going to do our due diligence."

NFL Insider Steve Wyche believes that the workout is the NFL's response to multiple teams inquiring about the 32-year-old quarterback. A league-wide workout would help to mitigate any potential political backlash that any one team may face for making an overture to the controversial figure.

Kapernick is an unrestricted free agent (UFA) so any team could have reached out to him. But it's believed that the interested teams are considering him for next season.

Earlier this year, Kaepernick and Carolina Panthers safety Eric Reid reached a financial settlement with the league in a joint collusion complaint. The players alleged that the league conspired to keep them out after they began kneeling during the national anthem in 2016.

Before the 2019 season, Kaepernick posted a video of himself working out on twitter to show he was in great physical condition and ready to play.

Kaepnick took the 49ers to the Super Bowl in 2012 and the NFC Championship game in 2013.

He has the 23rd-highest career passer rating in NFL history, the second-best interception rate, and the ninth-most rushing yards per game of any quarterback ever. In 2016, his career to a sharp dive and he won only of 11 games as a starter.

In the category of "claims to fame nobody wants," the United States can now add "exporter of white supremacist ideology" to its repertoire. Super.

Russell Travers, acting director of the National Counterterrorism Center, made this claim in a briefing at The Washington Institute in Washington, D.C. "For almost two decades, the United States has pointed abroad at countries who are exporters of extreme Islamist ideology," Travers said. "We are now being seen as the exporter of white supremacist ideology. That's a reality with which we are going to have to deal."

Between Alexa, Siri, and Google, artificial intelligence is quickly changing us and the way we live. We no longer have to get up to turn on the lights or set the thermostat, we can find the fastest route to work with a click, and, most importantly, tag our friends in pictures. But interacting with the world isn't the only thing AI is making easier – now we can use it save the world, too.
