Scientists from Japan have harvested solar energy using an exceptionally large number of light absorbers to relay photons via antennas into one final energy acceptor. This two-step sequence closely mimics natural photosynthesis, resulting in greater and more efficient energy transfer.

he Juneau-based beer maker has installed a unique boiler system in order to cut its fuel costs. It purchased a $1.8 million furnace that burns the company's spent grain — the waste accumulated from the brewing process — into steam which powers the majority of the brewery's operations. Company officials now joke they are now serving "beer-powered beer."

Shimizu, a Japanese architectural and engineering firm, has a solution for the climate crisis: Simply build a band of solar panels 400 kilometers (249 miles) wide (pdf) running all the way around the Moon's 11,000-kilometer (6,835 mile) equator and beam the carbon-free energy back to Earth in the form of microwaves, which are converted into electricity at ground stations.

From Popsci:

Today in mind-bendingly cool stuff that nanoparticles can do: A team of researchers at Rice University in Texas has demonstrated a mechanism by which they can create steam in just seconds by focusing sunlight on a mixture of water and nanoparticles. This isn't just some artificial means of lowering boiling point either; this solar powered "boiler" can produce steam before the water even gets warm to the touch, without ever bringing the aggregate water to a boil.

The research represents one of the first tallies of eagle deaths attributed to the nation's growing wind energy industry. A total of 85 eagles were killed at wind farms since 1997, the study concludes, but most of those occurred in 2008-2012. Most deaths – 79 – were golden eagles.
