How A City Can Get More Clean, Local Energy

Like many cities attempting to solve climate change at a local level, Minneapolis is finding the prospect more challenging that it may have imagined. The lion’s share of emissions (two-thirds in the case of Minneapolis) come from electricity and gas sold by two monopoly, corporate utilities. Minnesota’s state-level policy is … [continued]

Apologies, & News Update

I made a big mistake yesterday when I posted about my first update of the Cleantech, Climate, & Other Green News Google Doc. Well, actually, I made a big mistake before that. I didn’t initially make the doc available to the public! Luckily, a bunch of people requested access to the doc, … [continued]

Captured Rainbows, New Possibilities In Solar Energy Thanks To New Material That Slows Light

An improved method to capture rainbows has been developed by researchers at the University at Buffalo. The photonics breakthrough could very likely lead to significant improvements in solar energy, stealth technologies, and other areas of research, according to the researchers. The researchers created a “hyperbolic metamaterial waveguide,” that works to … [continued]

3-D Solar Cells May Receive Big Boost Thanks To New Semiconductor Nano-Shish-Kebabs

A new type of nano-sized structure, looking something like a “nano-shish-kebab,” has been developed by researchers at North Carolina State University. The seamless three-dimensional structure, consisting solely of germanium sulfide (GeS) crystals, could be useful in the development of 3-D solar cells, next-generation sensors, supercapacitors, and photodetectors. Looking like a … [continued]
