Photo: matze_ott
Ah, the product service system (or PSS): one of TreeHugger’s favorite concepts shrouded by one of the clunkiest names. For anyone who’d like a quick refresher, a PSS replaces a product with a service; instead of paying for the product itself (and whatever maintenance and upkeep it requires), you pay to use the product for a bit, and then give it back.

Wave Power With a Twist: Searaser Pumps Water Into Storage Ponds for On-Demand Ocean Hydropower

Here’s a wave power technology which you may not have heard of: It’s called the Searaser and (though only in prototype stages, I’ve got some reservations about how well it may scale up, as well as the name which somehow I always see as ‘Sea Eraser’) it may be worth watching.
The principle is fairly simple and proven in a different context: Use the Searaser to pump quantities of sea water up a hill where it can be stored in ponds until needed and then released downhill to drive hydroelectric turbines to create power. This is how the Searaser works:…

Young Children Building Antibodies to Cockroach and Mouse Proteins Face Environmental Health Risks
According to a study released by researchers at the Columbia Center for Children’s Environmental Health there’s reason to believe that the development of antibodies to cockroach and mouse proteins is associated with a greater risk for wheeze, hay fever, and eczema in preschool urban children as young as three years of age.
The study is the first to focus on the links between antibody responses to cockroach and mouse proteins and respiratory and allergic symptoms in such a young age group, and the implications for children who live in our inner cities where indoor air quality is often poor are truly significant.
