Power Management on Linux, Part 1

Power management on computers has three parts: selecting devices that are more power-efficient, tuning your systems to run more efficiently, and configuring systems to use less power during periods of inactivity. Servers, desktop machines, and laptops usually need different power management schemes; there isn't a one-size-fits-all. The first step is finding the power hogs on your systems, so today we'll learn how to measure hardware power usage. We'll also expose and rein in power-hog processes, and next week we'll learn some ways to get the most bang per watt on our Linux systems.

Nanotechnology packaging improves lifetime of organic solar cells

(Nanowerk Spotlight) Nanotechnology is already part of the process through which silicon-based photovoltaic solar cells - which make up some 95 percent of the solar cell market today - produce electricity. Nanotechnology is also the focus of research and development of a new generation of solar power technology that includes organic and inorganic solar cells derived from nanocrystals that can convert sunlight into electricity at a fraction of the cost of silicon solar cells.

Solar Company Says Its Tech Can Power 90 Percent of Grid AND Cars

90 The solar power plant company, Ausra, has released a paper claiming that solar thermal electric technology can provide 90% of US grid electricity, with enough left over to power a fleet of plug-in hybrids. The company estimates that change over would eliminate 40% of the country's greenhouse gas emissions with a land footprint of 9600 square miles (thanks, Kent).

Spin-Stabilized Microsatellites With Solar Concentrators

A document proposes the development of spin-stabilized microsatellites powered by solar photovoltaic cells aided by solar concentrators. Each such satellite would have a cylindrical or other axisymmetric main body with solar cells mounted in a circumferential beltlike array on its exterior surface. The solar concentrator would be a halo-like outrigger cylindrical Fresnel lens array that would be deployed from and would surround the main body, connected to the main body via spokes or similar structural members.

Tech That Will Save Our Species - Solar Thermal Power

NoMoreCoal writes "Salon has up a story by Joe Romm, former undersecretary of energy during the Clinton administration, discussing a lesser-known alternative energy solution. It's a technology that (he claims) is ready to provide zero-carbon electric power big, fast, cheap and (most importantly) right now: solar thermal power. 'Improvements in manufacturing and design, along with the possibility of higher temperature operation, could easily bring the price down to 6 to 8 cents per kilowatt hour. CSP makes use of the most abundant and free fuel there is, sunlight, and key countries have a vast resource. Solar thermal plants covering the equivalent of a 92-by-92-mile square grid in the Southwest could generate electricity for the entire United States.

Mass Megawatts Announces NEW Adjustable Augmenter (patent pending) to Lower the Cost of Electric Power

(BULLETIN BOARD: MMGW) (http://www.massmegawatts.com/) announces the development of a new adjustable augmenter (patent pending) designed to lower the cost of wind power. The new augmenter increases the wind power plant cost by only 30 percent, while generating five times the revenue. The augmenter utilizes a canvas panel system that funnels, and accelerates, wind into the company's Multi-Axis Turbosystem (MAT). The augmenter is expected to increase harnessed wind velocity by 70%, translating into an increase of over five times the power output at each MAT power plant.

Electric Solar Wind Sail Could Power Future Space Travel In Solar System

Power Integrations Introduces eSIP Power Package To Support Low-Profile Trend In Consumer Electronics

Power Integrations announced the availability of its TOPSwitch-HX series of ac-dc power conversion ICs in the new eSIP-7C Eco-Single-Inline-Package. This package exhibits the same low thermal impedance as the traditional TO-220, yet stands less than 10mm above the PCB – half the height of the 45 year old package, and takes less board space. eSIP-based designs reduce the overall height of the power supply in support of increasing market demand for slimmer electronic products such as LCD monitors, flat screen TVs and set-top boxes.

(Solar) power politics

Substantial improvement in essential cheap solar cell process

(Nanowerk News) A cheap alternative to silicon solar cells can be found in dye-sensitised solar cells. This type of cell imitates the natural conversion of sunlight into energy by, for instance, plants and light-sensitive bacteria. Annemarie Huijser has succeeded in substantially improving a process in this type of solar cell, which is similar to Grätzel cells. Huijser will receive her PhD on this subject from TU Delft on Tuesday 25 March.

Experts Hack Power Grid in Less Than a Day

bednarz writes "Cracking a power company network and gaining access that could shut down the grid is simple, a security expert told an RSA audience, and he has done so in less than a day. Ira Winkler, a penetration-testing consultant, says he and a team of other experts took a day to set up attack tools they needed then launched their attack, which paired social engineering with corrupting browsers on a power company's desktops. By the end of a full day of the attack, they had taken over several machines at the unnamed power company, giving the team the ability to hack into the control network overseeing power production and distribution."

Xbox 360 Power Supply Blamed for Arkansas House Fire

Beryllium writes "In Arkansas, an XBox 360's power supply (or power cord, the story is a bit ambiguous) apparently caused a fire with over $10,000 in damages. The fire chief says that it was probably due to the power supply unit being crammed into a space that had poor air circulation. The previously-documented heat issues with 360s led me to buy 'Andy', an affordable IKEA wireframe stand for my gaming system — with drawers! Since I've also got the power supply inside one of the unit's drawers, it should have more than adequate airflow to dissipate heat. I wonder what other airflow-improving ideas Slashdotters have come up with for their consoles?"
