Recycle Your Spent CFLs

Although CFLs have many environmental benefits, they do contain a small amount of mercury, and so need to be disposed of properly. But what does one actually do?

CFLs contain up to 5 milligrams of mercury, which is quite a small amount; compare that to older home thermostats and mercury fever thermometers, which contain from 500 to 3,000 milligrams. But given that nearly 300 million CFLs were sold in the U.S. in 2007, according to the Wall Street Journal, it can still be a concern. In several states tossing CFLs in the trash is even illegal.

Take them to your community's hazardous waste collection site. If you don't know where that is, call town hall, or look up waste management or public works departments in the phone book. Sometimes you can drop off items at a location any time, while in other communities there are designated days when they accept waste.

Or, if that's not convenient or an option, go with Sylvania's RECYCLEPAK program. Order a consumer pak on Sylvania's website ($15, including shipping), fill up with about 12 burned out bulbs, attach the prepaid shipping label, and your retired CFLs will be responsibly recycled. Larger sizes and community packs also available.

Disposing of used CFLs might seem like a bit of a pain, especially if you have to pay, but note that the recycling cost amounts to just about 1% of the total amount of money you'll spend on a bulb in its lifetime, since energy use is the lion's share. Also note that if you do have a broken bulb, don't handle it with bare hands. Pick up the fragments with a paper towel, seal in a plastic bag, and take to a recycling center. Ventilate the room thoroughly to push out any mercury vapor.

Parts of Nearly Extinct Tiger Openly Sold in Sumatra

Parts of the Sumatran tiger, a critically endangered species, are being openly sold in 10% of 326 retailers surveyed across the Indonesian island of Sumatra.

Although there are laws in place to protect the tigers, a lack of enforcement has led to the widespread sale of the tigers’ body parts in gold and souvenir shops and as ingredients in traditional medicine. The study, conducted by wildlife trade monitoring organization Traffic, estimated that about 23 tigers were killed to provide the products they found for sale. There are thought to be less than 500 Sumatran tigers left in the wild.

The rare and exotic animal is on the World Conservation Union’s “red list” of the most endangered species in the world. The Sumatran tiger is the last wild tiger found in Indonesia after Javan and Bali tigers were driven extinct from habitat loss and hunting for parts.

A 1999-2000 study found about 50 tigers on sale in the same area, but experts believe the decline in animals for sale is not due to a reduced demand but a reflection of the growing seriousness of this particular environmental problem. Lead study author Julia Ng said: “Sadly, the decline in availability appears to be due to the dwindling number of tigers left in the wild. The Sumatran tiger population is estimated to be fewer than 400 to 500 individuals. It doesn’t take a mathematician to work out that the Sumatran tiger will disappear like the Javan and Bali tigers if the poaching and trade continues.”

The trade in tiger parts has long been part of local culture. The bones and genitals of the tiger are used in Chinese medicine, while teeth and claws are put in jewellery that allegedly bring good luck. Other parts are used in magical protection charms.

While the government acknowledged that more needs to be done about the environmental issue, a statement from Sumatran official seemed to suggest problem was not a top priority. Dr. Tonny Soehartono of the Indonesian forest ministry said: “We have to deal with the trade. Currently we are facing many other crucial problems which, unfortunately, are causing the decline of Sumatran Tiger populations. We have been struggling with the issues of land use changes, habitat fragmentation, human-tiger conflicts and poverty in Sumatra. Land use changes and habitat fragmentation are driving the tiger closer to humans and thus creating human-tiger conflicts.”

The land use changes he refers to are almost certainly the increasing spread of palm oil plantations in Indonesia, an environemntal problem the government of the country has demanded cash to address. This has become a growing environmental problem as demand for palm oil for use in biofuels and food increases. Palm oil plantations are becoming infamous for their attitude towards native animals and forest dwelling people. Habitat loss from the expansion of the plantations, as well as poaching by plantation employees, has been driving down the number of a variety of native species including the Sumatran tiger and the orangutan.

Solar + Hydrogen Power Interstate Rail coming to Michigan!

by Mahesh Basantani

What do you get when you combine the innovation of MagLev technology with solar power, hydrogen fuel, and a futuristic aesthetic? The Interstate Traveler Hydrogen Super Highway, or the Traveler- a ground-breaking solar powered, hydrogen-fueled, zero emission mass transit system that would carry everything from people to cars in sustainable style and carbon neutral function. The construction is set to begin this year, and would connect Ann Arbor and Detroit.


The highway is made up of a slew of systems called the rail conduit cluster and will provide a comprehensive integrated system of the public/private transit system and municipal infrastructure network. It would serve as public transport system AND distribute electricity, potable water, liquid waste, fiber optics, hydrogen, oxygen, and fuels.

The public transit component would combine high speed magnetically levitated (MagLev, which we’ve seen in wind turbines before) cars running on parallel magnetic rails, laminated solar cells, and the conduit cluster that would be used to distribute electricity, water, fuels, etc. (It has been projected that each mile of rail would produce about 844,800 watts of electricity per hour at peak time using the solar energy). As for fuel, hydrogen would be used in fuel cells, internal combustion engines, micro turbines and other energy conversion devices to generate power.

The entire conduit cluster operations would be managed by TCP/IP technology. The Traveler Stations would be built to provide easy access to the Interstate Highway, solutions to overcrowding, urban sprawl, public utility failures, traffic jams, car accidents, etc.

The Interstate Traveler Project is the brainchild of NEWTY Award recipient Justin Eric Sutton. The construction for the first phase would start in Michigan in 2008, and would link the cities of Ann Arbor and Detroit.
