Astronomers have used NASA's Chandra X-ray Observatory and a suite of other telescopes to reveal one of the most powerful black holes known. The black hole has created enormous structures in the hot gas surrounding it and prevented trillions of stars from forming.
Let’s finish 2013 this way: With a vow to spread the word about the difference between watts and watt-hours, between power and energy.
In a high-profile critique of utility-scale renewable energy, Robert Bryce wrote in the New York Times in 2011 that energy sources like sunlight and wind “(require) vast amounts of natural resources – most notably, land.”
In an effort to prove that it can be almost as menacing as China, Iran has apparently hacked a bunch of US energy companies.
It seems that the US government’s belief in the efficiency of its private sector to run its power infrastructure is proving completely bogus.
Toyota has been on a bit of a tear lately when it comes to examining the intersection of transportation and sustainability. It, for example, showcased at the recent Shanghai Motor Show the FT-HT hybrid concept and also unveiled the all-electric Me.We vehicle as a study in ecological responsibility.
I’ve always loved Voltaic System’s habit of slapping a solar panel on just about anything one could carry around during the day. Backpacks, tablet covers, or laptop bags all become doubly useful once they’re capable of powering the gadgets within.
Waves may not be that predictable, even though technology and forecasting has improved (from World War II, when wave forecasting began in earnest, thanks to the requirements of the D-Day landing, up through the sophisticated models used by sports organizations like Surfline today), but the tides are thoroughly predictable.
In the aftermath of Sandy, mobile solar power – both on a fairly big scale and the cell-phone charging level – came to the rescue of some powerless residents.
The pro-gun control and pro-firearms folks are having a bit Scrooge post-Christmas as a New York newspaper (Journal News) posted an interactive map highlighting licensed gun owners, including their names.
Researchers at the Los Alamos National Laboratory have developed a simple, robust fission reactor prototype that could be used as a power system for space travel.
University of Oxford researchers say it should soon be possible to do away with the tangle of cables most of us are afflicted with, thanks to a new class of metamaterials.
There is one thing most people probably don't know about offshore wind.
There's enough power available in winds to meet the whole of the world's energy demand, says a Carnegie Institution for Science report.
Everyone knows that big solar arrays that can track the sun will deliver more power than fixed-tilt systems.
It seems like everyone in the industry wants to compare ARM (and other variants of RISC processors) to x86 (and other variants of CISC processors).
The USB 3 Promoter group recently finalized a fresh spec for USB power delivery of up to 100W of juice.
Scientists have fired off the most powerful ever laser pulse, hitting 500 trillion watts.
An Australian student has created a levitating lightbulb that powers itself wirelessly.
ARM currently dominates the lucrative mobile market (smartphones and tablets) with its low-power sipping RISC chips. And Intel?
