| Design team taps WKU student
A college senior from Western Kentucky has been selected to work on a global design project to create a wind-powered water purifier to benefit impoverished areas that lack electricity. Zach Pearl, who is studying mechanical engineering at Western Kentucky University, is part of the five-member team contributing to the project from around the world. "Something like this could possibly be used where there isn't a safe source of drinking water," Pearl said. "This could save lives." The research is still in early stages, he said, but the group is using computer-generated conceptual drawings to examine the possibility of harnessing wind power. It's not Pearl's first attempt to design a water purification system. Last year he was part of a team that created a water purification system powered by pedals on a bicycle.
Erosion-control holdouts being sought for project
In the Lake Tahoe Basin, the letters "BMP" can bring about various reactions.
Short for "best management practices," BMPs are methods prescribed by the Tahoe Regional Planning Agency to help developed properties function more like natural, undisturbed forest and meadowland. The TRPA believes that water conveyed to a lake by an undisturbed watershed usually is quite pure, because the watershed's soils and plants act as a natural water-purification system.
BMPs prescribed for residential properties usually fall into the following categories: vegetating and mulching bare, disturbed soils; infiltrating stormwater runoff from impervious surfaces; paving dirt driveways and roads; and stabilizing or retaining steep slopes and loose soils.
But for some of the 38,000 property owners in the basin who have not retrofitted their land for BMPs, the requirements can be harsh and expensive.
Hip-Hop Rumors: LaLa Plumps Up, Amerie Dropped? AHHmerican Gangster!
Somebody hit me with this as an explanation as to the title of Mariah's new CD, E=MC2.
“Just to clarify your Mariah E=MC2 comment it has nothing to do with Eminem. E stands for Emancipation(as in the title of her last album) MC is self explanatory and the 2 or squared simply means part 2. Emancipation of Mariah 2 but doesn't E=MC2 sound alot better."
Ddot the King hit me with that.
Charlamagne from Wendy Williams said this:
“Come on illseed! Mariah's album title is E for Emancipation the MC for Mariah Carey and the 2 represents the Sequel - Emancipation Part 2."
LMAO! I didn't really think that the E meant Eminem, but it's more interesting that way.
No-compromise mild hybrid car engine has a promising future
Several alternative technologies have been proposed to replace the car's internal combustion engine; some companies are already marketing hybrid gasoline/electric hybrids, though these have their shortcomings. Jon Severn reports on a mild hybrid that makes no compromises, yet it drastically cuts fuel consumption and emissions. Most of us, as consumers of the automotive industry's products, would like to see the next generation of cars have improved performance, driveability that is better or no worse than what we have now, more gadgets, lower fuel consumption, and a price that is lower. Largely on our behalf, the industry and legislators would also like future vehicles to generate reduced emissions, though there is an ongoing argument over where the balance should be between CO2, NOx and, for diesel-engined cars, particulates; Europe and Japan agree rather more closely with each other than with the USA.
