Some plastics should be classified as hazardous, scientists say

Less than half of the 280 million metric tons of plastic produced each year ends up in the landfill.  A fair bit of the rest ends up littering the landscape, blown by the wind or washed down streams and rivers into the sea.

So far Americans spend $520 million a year to clean up plastic litter washing up on West Coast beaches and shorelines. Efforts to clean up the oceans' enormous swirling gyres of garbage has an incalculable cost. Thus, much of the focus has been on how to stop the river of trash from entering the ocean. http://www.latimes.com/news/science/sciencenow/la-sci-sn-some-plastics-should-be-classified-as-hazardous-scientists-say-20130212,0,7219100.story?track=rss

A Silver Lining

A bold transit experiment over at Logan International Airport seems to be working.

Starting last June, the MBTA stopped collecting fares from arriving air passengers boarding Silver Line buses at the airport. The change had two positive impacts at Logan:  Passengers could board buses at the airport much more quickly and they could get to South Station and other points on the MBTA system for free. As a result, ridership on Silver Line buses traveling from the airport to Boston is up about 18 percent.

Sunlight stimulates release of carbon dioxide in melting permafrost

Ancient plant and animal matter trapped within Arctic permafrost can be converted rapidly into climate-warming carbon dioxide when melted and exposed to sunlight, according to a new study. http://www.latimes.com/news/science/sciencenow/la-sci-sn-carbon-sunlight-permafrost-20130211,0,5550833.story?track=rss

Space Age Transit System to Debut in Tel Aviv

Source: Israel21C
If all goes as planned, within two years Israelis will be the first people to try out a futuristic rapid transport system designed by NASA's Ames Research Center in Silicon Valley, California. The skyTran uses two-person modules that drive along a guide rail suspended from existing power lines. Magnets in the vehicle create a magnetic field around the metal coil inside the rail, causing the vehicle to lift up and glide 60 miles per hour on a cushion of air. The system uses very little energy and potentially could be powered entirely by solar panels. The space-age skyTran combines aspects of public and private transportation. "People often don't use mass transit because they don't like to share vehicles, they don't like having to get to a station and they don't like to follow someone else's schedule," says CEO Jerry Sanders. The cost of implementing skyTran is estimated at $9 million per mile, as opposed to $100 million per mile for a light rail system and $20 million per lane for buses. https://netforum.avectra.com/eweb/DynamicPage.aspx?Site=ACT1&WebCode=ACTeNews

Too bad Zipcar isn't taking over Avis

If Zipcar were buying Avis, instead of the other way around, the Cambridge-based car-sharing company's fans would be happier today than they are.

This should be good news. The car rental giant's $500 million purchase of Zipcar is great for stockholders, since Avis is offering 49 percent more per share than Zipcar's closing price Friday. In theory, the takeover is also a half-billion-dollar validation of the idea of car sharing; what once seemed like a utopian social experiment increasingly looks like a mainstream, even essential service for city dwellers who only drive every so often. It should help that Avis buys a lot of cars; Zipcar will be able to buy vehicles more cheaply and make more of them available at peak times. Avis, in turn, gains a foothold in a growing business that archrival Hertz is also pursuing aggressively. http://www.boston.com/bostonglobe/editorial_opinion/blogs/the_angle/2013/01/too_bad_zipcar.html

New Lake Tahoe plan to allow higher density development

Lake Tahoe towns will grow taller and denser under a new regional plan that supporters hope will quell a rebellion by Nevada against land use regulations that have restricted development in the basin.

The new plan is intended to rid the area of some of its midcentury strip development and turn town centers into more inviting, greener destinations that will revive the area's ailing economy. http://www.latimes.com/news/local/la-me-lake-tahoe-20121225,0,1292195.story
