We found that most solar homes in Rhode Island take part in what is called "net metering." This involves connecting your solar system directly to the power grid. When you are making a lot of solar power, it flows into the grid. When you are not, like at night, power flows from the grid to your home.
A typical system costs in the $12,000 to $25,000 range, but the federal government is offering a 26 percent tax credit this year. The credit goes to 22 percent in 2021 and to zero in 2022, so this is a reason to move fast on installing solar.

To catch an interstellar visitor, use a solar-powered space slingshot | MIT News
To ensure the best coverage of our solar system, MIT Assistant Professor Richard Linares envisions a constellation of "statites" that communicate and work together, only activating the statite in the optimum position to fly by or rendezvous with an interstellar object successfully. Other statites in the constellation can continue to wait for the next ISO to appear.

In 2017, a telescope in Hawaii detected our first celestial visitor from another solar system — a big deal, since we haven't quite figured out how to visit them ourselves yet. 'Oumuamua, the cigar-shaped interstellar object (ISO) whose name roughly translates to "first distant messenger" in Hawaiian, will certainly not be the last visitor to pass through.
REC Solar completes first phase of solar + storage system for Hawaiian freight company
REC Solar, an unregulated affiliate of Duke Energy, has completed a solar microgrid solution for ocean and air freight company DHX (Dependable Hawaiian Express).
The vision for renewable generation combined with energy storage as a backup power supply came long before DHX opened its environmentally friendly facility in Honolulu last August.
"When your company's first name is ‘dependable,’ you better have a power system that is too," said DHX President Brad Dechter. "Still, my commitment to going green isn't just about reliable energy and saving money. I have a granddaughter who is seven, and it's as much about saving the planet for her future. The key for me was finding the right expert."

In a paper posted September, 2019 to arXiv, physicists James Unwin , University of Illinois at Chicago and J akub Scholtz at the University of Durham in the United Kingdom, showed that the likelihood of our Sun capturing a free planet, one of the possible explanations for the origin of the long-sought hypothetical Planet 9, is very similar to the likelihood of capturing a black hole based on gravitational anomalies thousands of light-years toward the center of the galaxy that were recently
This may worth something:

Regular reader Linda from Frankfort asks, "How will we know if we find aliens?" As I said to another reader (Marty — also from Frankfort) who asked about the motion of the Moon, the answer is complicated. Too complicated to answer in a single column.
The first is liquid water. Until recently, we believed that a planet had to be within a certain distance from its parent star for liquid water to exist. The Hubble Space Telescope, Voyager and Cassini missions have discovered liquid water oceans on worlds 10 times farther from the Sun than we thought possible.
NASA's Neil Gehrels Swift Observatory Tracks Water Loss from Interstellar Comet 2I/Borisov |
Astronomers using NASA's Neil Gehrels Swift Observatory have tracked water loss from 2I/Borisov, the first known interstellar comet to visit our Solar System, as it approached and rounded the Sun. Their findings were published in the Astrophysical Journal Letters .
Hubble captured this image of the interstellar comet 2I/Borisov on December 9, 2019. Image credit: NASA / ESA / Hubble / K. Meech, University of Hawaii / D. Jewitt, University of California, Los Angeles.
I'm a space archaeologist studying junk strewn across the solar system | New Scientist
I’m a space archaeologist. I study the artefacts and sites that are evidence of human engagement with outer space. I’m interested in how humans use objects to adapt to different space environments, whether that’s through orbital robots or Velcro, which was popularised after it was used in NASA space missions.
* * *
I use archaeological methods and theories to investigate the culture of space exploration. It’s about how space technology changes through time, and how it reflects social and scientific beliefs. While history focuses on the …
