Air-Purifying Concrete Paving Stones Remove Nitrogen Oxides from Vehicle Emissions
Researchers from the Eindhoven University of Technology in the Netherlands claim to have invented a new type of paving material that actually removes some pollutants from the air as vehicles travel over the surface. Combined with concrete or normal asphalt, the new material is able to eliminate 25% to 45% of nitrogen oxides from vehicle gases.
President Obama Allocates $2 Billion for Solar Energy
The money promised by Obama will come from government stimulus funds designed to boost the economy during the recession. According to the president, about 5,000 new jobs will be created due to these investments.
EU Prepares Massive Investments in Renewable Energy
According to an analysis made by Reuters, the wind turbines will rapidly expand in Europe's coastal waters, bringing new opportunities and challenges for the industry.
Jake Explains How to Build a Super-Cheap Solar Water Heater
Solar water heaters are not a new idea, but people who often complain about rising energy prices should be reminded to use such devices to help heat their homes and take a shower, too.
Research: Postponing 5 O'Clock Tea By 1 Hour Could Offer Huge CO2 Savings
You surely remember how it's like in winter: you wake up, it's dark, you turn the lights on. When you go to work, there's finally more light, but when you return at around 5, say, it's dark again, and you feel like you've been missing the whole day. But that's not the point. The idea is that you consume much more electricity and resources if your schedule doesn't match the daylight.
New Study Estimates Impact of Soot on Global Warming and Timeframe of Actions to...
Soot is considered one of the most important threats to the environment, along with carbon dioxide. Princeton University researchers have described the contribution of soot ("carbonaceous aerosols") to phenomena of global warming and global dimming. Soot is born by incomplete combustion and comes mostly from diesel engines and coal burning.
Recently Discovered Nanocoating Makes Heat Transfer Happen Much Easier
The action of cooling things down plays a critical part of any mechanical or electric system, because the inevitable heat, produced by friction, is the number one cause of almost instant failure. So far, different methods that cool systems have been discovered, but not to the extent of performance that engineers dream of building their computers or mechanical devices (cars, for example).
Good News: Global Greenhouse Gas Emissions Dropped by 1.1 Percent in 2009
Among the dozen of bad news that keep filling our mailboxes daily, we once in a while read something worth smiling at: the global greenhouse emissions generated by energy use dropped for the first time since 1998, by 1.1 percent. Through this, the economic crisis has its good actions, because it reduced the industrial production and fossil fuel consumption worldwide.
An Idea to Naturally Harvest Algae for Biofuels By Using Stable Ocean Currents
Here's an interesting idea to cultivate algae that could be transformed into biodiesel. The basic idea is that people should use the stable currents that exist in the Pacific ocean to carry algae from one point to another, time during which the algae should mature with the ocean's support and some slowly-dissolving nutrients that should float along with them.
Dutch Scientists Say Reducing Speed Limits to 50 MPH Would Cut CO2 Emissions by...
Holland is a country many people mention for its cleanliness and low-speed driving (120 km/h max on motorways). Still, there's room for more, as Mattijs Otten and Huib van Essen from the University of Delft released a study saying that the CO2 emissions would be reduced by 30% in the long run by reducing the speed limit to 80 km/h (50 mph).
