If you’ve walked through Carleton’s campus in Ottawa, you may have seen him: A young man working away on a wooden structure just outside the architecture building. He’s building a tiny house, but it isn’t for him — it’s for his mother to live in year-round in Edmonton.
It hadn’t occurred to me that there might not be enough acreage to support utility-scale solar electricity. It turns out that not everyone wants a PV farm in their backyard. And I hadn’t considered the trade-off between lots of available sunshine (Death Valley) and lots of electricity users (not Death Valley). So….PV site developers have figured out some ways of making their installations more neighbor-friendly.
“Conventional solar installation techniques typically involve turf grass and gravel as ground cover, which removes vegetation and flattens landscapes, according …. These methods lead to high preparation and labor costs, expected to account for 20% of the price of photovoltaic installations by 2020.
“Conversely, seeding solar grounds with native plant species provides agricultural and ecological benefits that gravel and turf cannot, such as better stormwater control because of plants’ deeper roots. Seeding can also boost solar efficiency by creating a cooler microclimate around the panels, which boosts solar efficiency, said Gavin Meinschein, a lead civil engineer at ENGIE Distributed Solar.Although the upfront costs for seeding are higher than installation of turf grass, the maintenance over projects’ 25-30 year lifespan is cheaper because it’s less involved, Meinschein said.Native plant sites can double as pollinator-friendly sites, an “irresistible synergy,” said John Jacob, who founded Old Sol Apiairies in 1997 and now works with solar developers to integrate bee farms and solar developments.The pollinator benefit is a specific twist to the story that has gotten buzz in local and national media.” ….Story continues…..
There’s a video embedded in article – about a fast-growing company in Cleveland that makes vinyl records. Lots and lots of vinyl records.
The video shows the techniques that go into producing limited-run vinyl records and it also shows the human contribution that goes into each record. There’s no room for robots in this plant.
The big take-away for me from this article is that scientists don’t know where all this stuff (water, mass, life, consciousness, etc) comes from.
Fascinating article from 2009. If life exists in other parts of our solar system it is probably “left handed” in the sense that the amino molecules of life on Earth are left-handed. But life in other parts of the universe might be right-handed.
A couple of days ago…Eureka! I cut out a little post-it note and put in on top of the Del key. Problem solved? No, it wasn’t solved.
Now when I need to delete something, the Del key is easy to see but, unconsciously, I avoid touching that red key. I find myself (days of occasional use later) seeking the Del key on either side of the red key.
