Solar Map Helps Decide If Panels Are Worth Installing
MIT's Solar System software combines several sources of data to create a map that can predict the annual yield of a panel array installed at a given location.

What's the Latest Development?
MIT scientists have created software that can determine the solar energy potential of a geographic area taking into account such things as climate and building obstruction. The software, called Solar System, combines Google satellite images with Light Detection and Ranging (LIDAR) survey data to create a 3D model of a city that details the shape of rooftops and identifies any trees or other barriers to light reception. To demonstrate the system, the scientists mapped all 17,000 rooftops in Cambridge, MA and designed an interface that allows residents to look up their homes and see the potential value in installing a solar panel array.
What's the Big Idea?
In the past, solar maps of this type made one of two assumptions: "[E]very rooftop is completely flat, or [the] ratio between direct and diffuse solar irradiation is fixed throughout the year." By accounting for the differences, the team was able to create a map that predicted far more accurate energy yields compared to earlier versions. In the case of Cambridge, the tool showed that if all the areas considered "excellent" or "good" had solar panels installed, together they could deliver up to one-third of the city's energy needs.

Giving our solar system a "slap in the face"
- A stream of galactic debris is hurtling at us, pulling dark matter along with it
- It's traveling so quickly it's been described as a hurricane of dark matter

Bernardo Kastrup proposes a new ontology he calls “idealism” built on panpsychism, the idea that everything in the universe contains consciousness. He solves problems with this philosophy by adding a new suggestion: The universal mind has dissociative identity disorder.
There’s a reason they call it the “hard problem.” Consciousness: Where is it? What is it? No one single perspective seems to be able to answer all the questions we have about consciousness. Now Bernardo Kastrup thinks he’s found one. He calls his ontology idealism, and according to idealism, all of us and all we perceive are manifestations of something very much like a cosmic-scale dissociative identity disorder (DID). He suggests there’s an all-encompassing universe-wide consciousness, it has multiple personalities, and we’re them.
Once again, our circadian rhythm points the way.
- Seven individuals were locked inside a windowless, internetless room for 37 days.
- While at rest, they burned 130 more calories at 5 p.m. than at 5 a.m.
- Morning time again shown not to be the best time to eat.
