- Are you ready for your monthly dose of technology advances? Even if you are not, here we go:
This system produces hydrogen gas from sunlight and ambient carbon dioxide.
Inexpensive catalyst makes organic fuel cells a possibility.
This algae strain filters arsenic out of water.
A new idea for storing excess energy generate by ocean wind turbines.
- For this news snippet we pivot away from the monthly NOAA climate reports looking instead at the annual global report. And as you might expect, it was a hot year on planet Earth, in fact it was the 6th hottest on record at some 1.51°F (0.84°C) above the 20th Century average; it was also the 45th year in a row with temperatures above the 20th Century average. And then the years 2013 to 2021 all rank in the top ten hottest on the planet – a clear and disturbing trend that has received little attention here in America and in China, the world’s largest greenhouse gas emitters.
- Did you know that February 8th is National Kite Flying Day? Well neither did we! But in honor of this majestic holiday, our Google search of the month was, “Kites and GIS.” And well sometimes we learn about new imagery sources when drafting this piece as we did this month, that being kite aerial imagery! Check out this short but sweet abstract by H. Wirth and N. Winn abouth their experience making digital elevation models from imagery collected on a kite.
- As we continue our review of online GIS resources, last month we were in Columbus, Georgia, the third largest city in the state; and for this month we travel to our island state Hawaii with a review of their fourth largest city’s online resources (we had to skip the third largest city as it is unincorporated), Hilo. And given the size of Hawaii in general, Hilo’s website is actually a part of the County of Hawaii’s site so we review that instead:
Hawaii County GIS Website
Hawaii County GIS Contacts
Hawaii County GIS Web Map
Hawaii County GIS Map Collections
Hawaii County GIS Direct Downloads (try emailing the GIS team for downloads as we see no other way to do this on their site)
