Website Maps Air Polluters Across U.S.

There's been a surge of websites using Google Maps for environmental good. Joining the ranks is Planet Hazard, a website using the technology to map air polluters across the country.

The website uses data from the EPA's National Emission Inventory Database to allow users to view polluters on a national, state, county or city level. Beyond the name and i use it natural viagra pills location of the 86,320 polluters included, the exact pollutants being emitted and their quantities are listed for each company. The site includes a list of the top ten polluters in the country with Regional Sanitation District based in Elk Grove, Ca. topping the list. Ammonia makes up the largest chunk of click now buy cheapest cialis its emissions.

I looked up my city and found the usual culprits like energy, industrial and manufacturing companies, but was surprised to see all the major hospitals listed. The main pollutants they are emitting are nitrogen oxides, most likely from burning fuel to heat the buy cialis australia buildings. Of course, the hospitals significantly trail industrial sources in quantity of pollutants released.

The one thing to keep in mind is that the figures are from 2002, the last time that the EPA collected air emissions data, so it's possible that there are newer polluters that aren't included or that some of those listed are now closed. It's still a valuable resource for all of us who are interested in knowing exactly what is in the air we breathe and which companies are responsible.

UK Scientists Launch Underwater Robots to Track Climate Change

The UK's National Oceanography Center has developed and launched three Autonomous Underwater Vehicles into the Atlantic Ocean to detect signs of climate change. The AUVs will profile the natural viagra top 1,000 meters of the ocean from the Canary Islands to the west coast of Africa.

The battery-powered gliders are equipped with GPS and satellite communication technology and will transmit information on temperature, salinity and buy levitra us other current levels back to i recommend online viagra prescription the center three times a day. Their main task is purchase levitra in canada to monitor the heat circulation in the Atlantic that many scientists believe could slow down and, if it were to stop, could throw us into the next Ice Age.

These robots, if successful, will join a team of 25 other instruments that are continually monitoring data in locations throughout the Atlantic. The data these instruments are collecting will be able to tells us when changes occur and allow us to start planning a response more quickly if the worst seems to be on the way.

Wilting Flower

A British designer has come up with the Wilting Flower as a way to raise awareness of home energy consumption. The device is shaped like a flower that provides a visible reminder of how much energy is being used at the moment. When low amounts of energy are being consumed, the flower stands tall and blooms open. Flick on more lights and turn on the TV or video game and the flower wilts and closes up.

The prototype is expected to buying online propecia cost about $90 when it comes to the market. So why would someone buy this novelty device when a simple energy monitor would do the exact same thing? Designer Carl Smith, who came up with the Wilting Flower, told the Daily Mail that he hopes people will become attached to the flower and keep it in bloom by changing their energy consumption habits. Other products display energy use on small LCD units which are not as attractive, he says.

A wireless connector is connected to the household electricity supply and when more appliances are turned on, the amount of current drawn increases and is relayed back to the Wilting Flower. When the flower displays a blue and greenish light, that means power usage is low. Purple is a bad sign and an indication that the flower is about to wilt and it's time to turn off some of those appliances.

Carbon-Monitoring Spacecraft Arrives at Launch Site

NASA's Orbiting Carbon Observatory has arrived at Vandenberg Air Force Base in California where it will launch in January 2009. The observatory is NASA's first spacecraft designed to study carbon dioxide.

The spacecraft will spend two years in a 438-mile, near-polar, sun-synchronous orbit. It will map the globe every 16 days and collect information about levels of CO2 in the Earth's atmosphere. Three high-resolution spectrometers that spread reflected sunlight into its various colors will provide scientists data about the gases present. Scientists will then be able to estimate the viagra com monthly volume of CO2 over a given 621-mile region.

This observatory will allow to scientists to see where CO2 is collecting in the atmosphere and what human activities are contributing to it and wow it's great get viagra in canada what parts of buy cialis now online the world are acting as sinks. Most importantly it will allow more accurate measurements of total CO2 in the atmosphere and enable more reliable predictions of future climate change.

I have to say I am really excited about this spacecraft. This is a great use of NASA's technology to help solve a problem that is affecting us here on the ground. This observatory is going to give us invaluable information on what we're up against in the fight against climate change.

Miniature, Super-Sensitive Greenhouse Gas Sensor Being Developed

A new miniature greenhouse gas sensor called MINIGAS is being developed by VTT Technical Research Centre of Finland. The super-sensor will be less than an inch long, twice as sensitive as current sensors and cheaper too.

In fact, the European Union has such high hopes for this sensor, they've invested $3.6 million in the project and created a consortium or European companies and research organizations to aid in its development.

In addition to greenhouse gases, the sensor will be able to detect explosive vapors and chemical agents like nerve gas, making it useful for governments in homeland security systems. Environmentally conscious consumers will also be able benefit from the sensor since cost effectiveness is a high priority.

No word yet on a timeline for the sensor's release, but it's encouraging to know that European governments will be the first in line to use it.
