MP3 players and digital Science

I'm climbing up the audiobook learning curve and would like to share what I've learned. My first post on this topic can be found here. I was experimenting with the cheapest MP3 player I could find that would play free audiobooks from a library.

Apple's iPods will not allow you to listen to free audiobooks. First lesson learned: Do not use the cheap players. I have purchased four of the low end products made by Coby, starting with the cheapest and moving up the line. They all failed within days to weeks. Luckily I received a full refund for each, which is why I bought locally instead of off the internet.

The Midwest will suffer if we don’t change our approach to flood protection

We've heard a lot this week about how the floods in the Midwest might be an act of humans -- or an act of City Council, as one Iowan leader put it. We can start the futile cycle of fighting Mother Nature again if we want to: spend billions of dollars on levees and flood control infrastructure, encouraging development of river floodplains and low-lying wetlands, then watch those homes and businesses be overrun by flood water.

 

A UN Dispatch-Grist collaboration

This week marks the twentieth anniversary of NASA Scientist James Hansen's groundbreaking Congressional testimony on global warming, an event that put climate change squarely on the political agenda. In honor of the anniversary, UN Dispatch, On Day One, and Grist are partnering to discuss ideas the next president can adopt to take on climate change. We are joined by a panel of experts who will weigh in on ideas submitted to On Day One by everyday users concerned about the climate crisis.

Our first idea comes from On Day One user wise old owl, who suggests we decentralize energy production.

Decentralized energy production through use of renewables (roof-top solar as well as solar farms, together with geothermal, tidal, and wind) can be transferred across our national grid to areas where it is needed from areas with higher productivity and/or lower need, which would change on a dynamic basis. This would eliminate centralized generating facilities as "targets" for terrorists, and eliminate the "control mentality" of large, centralized for-profit utilities.

Grist writers Kate Sheppard and David Roberts; President of Climate Advisers Nigel Purvis; and Timothy B. Hurst of Red, Green and Blue and EcoPolitology, each respond below the fold.

Umbra on car seat recycling

Dear Umbra, What do you recommend for child car seat disposal or, better yet, recycling? Near as I can tell, options include giving them away to someone who needs them (a pretty discouraged practice) or sending them to Oregon or Colorado where a couple of renegade recycling programs are working to resolve this huge issue. […]

Obama calls for regulation of oil markets and decreased dependence on oil

On Sunday, Barack Obama promised to end unregulated oil speculation and close the “Enron loophole,” which he says are at least partly to blame for rising gasoline prices. “For the past years, our energy policy in this country has been simply to let the special interests have their way — opening up loopholes for the […]

McCain calls for $300 million prize for the designer of a better electric-car battery

Republican presidential contender John McCain gave a speech in Fresno, Calif., today calling for a $300 million prize, paid by the government, to be awarded to the person who can design a better electric car battery. “This is one dollar for every man, woman, and child in the U.S. — a small price to pay […]

‘Dell of solar’ seeks to make it cheap and user-friendly to get rooftop PV

Today, a company called Sungevity announced the availability of what they’re calling the cheapest solar system in the world: a rooftop solar panel system, fully installed, for $2,000. That’s as much as I paid for my computer. For that price, the average home will save $21,000 in electricity over 25 years — a 45 percent […]

Enviros’ border-fence appeal turned down by Supreme Court

Homeland Security officials can continue to waive environmental laws to speed construction of a fence on the U.S.-Mexico border, after the U.S. Supreme Court declined to hear an appeal by Defenders of Wildlife and the Sierra Club. The groups had argued that the eco-law-waiving power given to Homeland Security chief Michael Chertoff in 2005 was […]

Prez candidates tout new policies to lower oil prices

John McCain and Barack Obama have both called for changes to national energy policy in recent days that they said would eventually help lower oil and gasoline prices. On Sunday, Obama called for closer regulation of oil speculators that have been a major force contributing to the rise in oil prices. He said his plan […]
