Staggering Video of Our Nation Exhaling CO2

Scientists at Purdue university recently did an extremely detailed analysis of the emission of CO2 in the United States. They included every sector: power generation, manufacturing, transportation, etc., and then they used advanced atmospheric models to track the gas. It's part of a research project they're calling "Project Vulcan," presumably because Vulcan's looking down at our planet would either be unimpressed by our technology, or wonder how an entire planet could breathe.

The result is both staggering and us pharmacy viagra unnerving. Watching our nation wake up in the morning in this way is just plain freaky. The CO2 swells into the atmosphere, covering more of levitra 50mg the nation hour by hour until folks start get home and start relaxing more, and consuming less.

I can proudly declare that my city in western Montana, in fact, remains completely unblemished by CO2 emissions. Though, it's easy enough to spot the coal-fired power plant in south-east Montana that actually powers my house.

Calculating your travel CO2 emissions

The French rail system (SNCF) has added a calculator for travel carbon emissions, offering up the ability to compare prices and carbon loads for travel by rail, air, or personal vehicle. L'Ecocomparateur enables one to know how long the trip will take and the consequences for the pocket and the climate for that trip.

Will you be willing to take a few hours longer in travel to save $50? How about if that will also cut your travel emissions load by 200 lobs or more? The trip Toulouse-Paris, for example, comes up with these figures:

  • Train: 57.90 Euros; 5 hours, 13 minutes; 9 kg CO2
  • Plane: 222.20 Euros; 1 hour, 30 minutes; 180 kg CO2
  • Car: 201.47 Euros; 6 hours, 46 minutes; 272 kg CO2

Time priority, this says take the plane. Money and carbon load: enjoy your train ride. Now, the behind the get viagra fast scenes rule sets for the analysis are worth exploring. (See here for the methodology for calculating emissions.) The system actually has a bias against trains (and cars) because there is no calculating for the difficulties and hassles for traveling by plane.

By experience, one can arrive at the Gare (train station) in Toulouse 2 minutes before the train and buy prescription levitrabuy levitra in the uk get on board (almost missed that one). The days of running through the airport like OJ Simpson, without a huge security line, are long gone.

Add another hour to the flight simply for the security issues. In addition, the train leaves/arrives in center city and the car at the doorstep, the plane far out of town, requiring additional transport, additional time and money to cialis soft pills get where you're going. Thus, oddly, the SNCF has given some advantage to the planes.

Googling Pollution

Google Earth rocks. We've seen it monitor illegal coal mining, keep tabs on reforestation, and inform the masses about environmental issues all over the globe.

But now the US EPA is using it to display nation-wide pollution sources and levels. You can zoom right in on your neighborhood and check out carbon monoxide levels and see the major sources for pollution in the United States.

The one major source of pollution not displayed on this map is transportation. As there are so many cars, and they're always moving around, the EPA can't keep tabs. But everything else is viagra 100 mg right there at your fingertips. Check out your town and see who your major polluters are.

Green Research Station in Antarctica

Antarctica is a frikkin' weird place to live. I've had a few friends spend time at maintenence workers, not scientists...and the overwhelming opinion is that people just don't belong. So while we've found our reasons to be there, it's important that we try not to leave much of a footprint.

It's also important to try to viagra canadian pharmacy be self-sufficient because, so frequently, you are entirely cut off from the rest of the world. And those are just two of the reasons why the government of Belgium recently comissioned the Princess Elisabeth Antarctica, the first zero-emission, manned scientific station in the world.

The station will be powered with 100% renewable energy, from the solar panels on the walls, to the six wind turbines on a nearby ridge. It is also designed to use 20% of the energy of comparable stations. The walls are extra-insulated, and the heating system will rely not only on cialis 40 mg europe regular heaters, but on passive generation from sunlight, and redistributing heat created by equipment.

The station has already begun construction, and will be installed in Antarctica this winter (summer, there.)

Hey There: Here Comes the Solar Fish

IBM has teamed up with a non-profit organization that studies the cialis 200mg health of estuaries and the best choice levitra online switzerland rivers to create several solar-powered, high-tech, autonomous vehicles for keeping tabs on the health of the Hudson River.

A 315 mile stretch of the river would be constantly monitored by solar-powered submersibles that would then beam data back to a central location for processing by IBM's special software. It's the first system of it's kind, but I've long expected to see this kind of monitoring in all our waterways.

Solar power allows the vehicles to be completely autonomous (as long as their programming is good enough) and they will basically be able to operate on their own for the life of their batteries. The submersible craft was actually built by Woods Hole Oceanographic Institute. Don't be surprised if, in the next fifty years, you start running accross these things in rivers, estuaries, reservoirs, lakes and oceans near you.
