A Problem For Smart Meters: People Don’t Understand Electricity

The general public has no idea how much they pay for electricity or how to use less, undermining the central premise of smart meters and hindering their adoption. Smart power meters are, in theory, supposed to help with everything from electric vehicle adoption (low electricity rates encourage people to charge up at specific times) to bringing more renewable energy on the grid (pricing will vary based on when it is available). But smart meter implementation hinges on the idea that consumers actually understand their electricity use.

Putting Old Tech In The Internal Combustion Engine Nets One-Third More Mileage

Using an engine design that was largely abandoned after World War II, new engines find fuel savings where big auto companies--weighed down by the inertia of their designs--can't. Decades of refining today's automobile engine technology has come to this: We're investing more and more, but getting less and less in terms of efficiency, performance, and durability

ClearEdge Wants To Put A Refrigerator-Sized Fuel Cell In Your House

If you have $60,000 to spare and like to show off to your neighbors, ClearEdge Power may have the product for you: a giant fuel cell that can power up your house, and perhaps take you entirely off the grid. Bloom Energy burst onto the clean energy scene last year with the Bloom Energy Server (you know it as the Bloom Box), a so-called fuel cell "power plant in a box" that can run on natural gas, hydrogen, or biogas. Bloom has cornered the big business fuel cell market, with installations at eBay's headquarters, multiple AT&T sites, Adobe's headquarters, and more

Are Category 6 Hurricanes Coming Soon?

Atmospheric researchers tend to agree that tropical cyclones of unusual ferocity are coming this century, but the strange fact is that there is no consensus to date on the five-point scale used to classify the power of these anticipated storms. In what may sound like a page from the script of the rock-band spoof Spinal Tap with its reference to a beyond-loud electric guitar amplifier volume 11, there is actually talk of adding a sixth level to the current Saffir-Simpson hurricane scale, on which category 5 intensity means sustained winds higher than 155 miles per hour (250 kilometers per hour) for at least one minute, with no speed cap

Optical fiber transmission quality can now be tested without the need to take measurements at both ends

Light traveling in an optical fiber loses power over distance. A number of factors are responsible for this power loss, but one that is particularly important at high data rates is the loss that occurs due to changes in light polarization. Hui Dong at the A*STAR Institute for Infocomm Research and co-workers1 have developed and tested a method of determining this polarization-dependent loss (PDL) in an optical fiber cable by taking measurements from just one end of the fiber
