The video is about solar power. The problem is that the narrator is more interested in telling us all about how clever he is (and presumably we aren't) than providing clear, concise, and coherent information. The technology may be a wonderful breakthrough in overcoming the costs of manufacturing photovoltaic cells but he makes it sound like he's selling snake oil.
That's what I thought as well Asbo.
scotthm made the comment about harvesting energy from the sun.
Harvesting energy from the sun would be solar power but harvesting energy from the sun using photovoltaic cells wouldn't cause dimming to take place.
Let's say that a planet was orbiting KIC 8462852 that had a photovoltaic harvester on the surface and was the same distance from KIC 8462 that Earth is. Because of the distance between Planet K and KIC 8462 there wouldn't be any gap in the amount of energy collected by the photovoltaic harvester.
But if Planet K is moved closer to KIC 8462 the amount of time that energy takes to reach Planet K is reduced significantly so that if the energy from KIC 8462 is being harvested the entire packet of particles emanating from KIC would be harvested reducing the overall brightness of KIC 8462.
Even a small planet, the size of Mars, with a large harvester on it's surface could possibly collect enough particles from KIC 8462 to cause the light curves recorded by Kepler and keep the planet from being detected.
If there is an alien species in the system of KIC 8462 living on Planet K maybe they have discovered a way to accelerate the energy transfer of solar energy as it emanates from the sun at the speed of light so that the area that the harvester was directed at would harvest the energy of KIC 8462 so fast and because of Planet K being closer than Earth is to our Sun would cause KIC to have a dim.
I'm not talking about a passive harvester that would collect energy from KIC 8462 by being a receiver but an active harvester that would collect all energy particles within it's cone of influence the moment the energy left the surface of KIC 8462852.

If aliens were harvesting the energy of KIC 8462 I think the logarithm of the harvest would be rather apparent which would be a continued up and down curve on a digital chart.
I for one am hoping for aliens but I have to discount as much as I possible can regarding natural events causing the dims of KIC 8462.
In this case the natural events causing the the 15% and 22% dims of KIC 8462 could have been Coronal Holes similar to the ones mentioned in the article. Like Kepler recorded the light curve of KIC 8462 was a massive dim. More massive than even the largest of Super Gas Giants would be able to create.
But Coronal Holes could create the massive light curves discovered on KIC 8462 which is the closest natural event being cause by KIC 8462 that would be possible out of alien intervention.
