Office Building Is 100% Sewer-Free
September 9, 2008 10:19 AM - , MetaEfficient
The sewer systems we use today are entirely ineffectual and unnecessary. The primary flaw in our design is that we use freshwater to dispose of feces. This is perhaps the most ineffectual thing to do with human manure — it pollutes fresh water, and it requires municipalities to maintain extremely costly sewage treatment infrastructures. Even after treatment, sewage can still wreck havoc on rivers and groundwater.
Bags Made With 95% Recycled Material
September 8, 2008 09:31 AM - , MetaEfficient
I’ve been testing a new line of bags called Terraclime by Lowepro. I was impressed by the fact that 95% of the material used to make these bags is recycled content. The fabric is made with recycled PET bottles (i.e. post-consumer plastic). The hooks and zippers are made from plastic salvaged from the factory floor, and reground.
An Inexpensive Electric Bike Conversion Kit
August 21, 2008 09:11 AM - , MetaEfficient
Sales of electric bikes have spun into high gear this year — some merchants like Amazon are reporting a 6000% increase this summer from last year. This is good news, because, for short trips, the efficiency and convenience of electric bikes is hard to beat.
New Zero-Emissions Commuter Bike: The A2B
August 14, 2008 10:33 AM - , MetaEfficient
A company called Ultra Motor has released a new electric bike called the A2B. This bike looks great - I like the functional, minimalist style. The A2B is designed for urban or suburban commutes. According to Ultra Motors, the A2B offers unassisted power on demand for up to 20 miles at a cruising speed of 20mph. At that speed it’s still categorized as a bicycle as opposed to a scooter, moped or motorcycle. No special license is required.
Solar Powered Air Conditioner Released

A company called GreenCore Air has released an air conditioner than can be powered by a single 170 watt solar panel. The GreenCore air conditioning unit can heat and cool a 600 square foot room. It runs on DC power, so there is no need to put an AC inverter between the solar panel and the air conditioner. This eliminates the power losses associated with converting AC to DC.
The First LEED Platinum Data Center

ADC (Advanced Data Centers), a company based in San Francisco, is set to build the country’s greenest data center. Because of its efficiency, the project stands to save its owner from $1.8 million to $2 million in energy costs. ADC says its new center will be 25-30 percent more energy efficient than the industry standard.
The Greenest Notebook Computers Of 2008
August 6, 2008 11:25 AM - , MetaEfficient
Earlier this week, we reviewed the greenest desktop computers, so now let’s take a look at the greenest notebooks! Notebooks are typically much more energy efficient than desktops. They are, however, no greener than desktops in other regards — they typically contain the same hazardous components, and they are not easily recycled. However, a few green notebook computers are now on the market. Here’s a short survey of the greenest ones available:
The Greenest Desktop Computers Of 2008
August 5, 2008 11:04 AM - , MetaEfficient
At MetaEfficient I’ve been waiting for years to review some exciting green computers, and now finally in 2008, we’ve seen the introduction of some truly green PCs. Although the components of green PCs cost about 10% more than regular PCs, they retail for about the same price. You can jump ahead and see our list of the greenest PCs. Or you can read about the details of the green rating processes.
Motion-Sensing LED Lights: A Review
August 4, 2008 11:16 AM - , MetaEfficient
Motion-sensing LED lights — these lights are perhaps the most efficient lighting devices available today. They switch on whenever their infra-red sensors detect movement in a room — such as when someone begins to walk down a dark hallway. I’ve been testing them in my own home, and I’ve found them to be effective and non-obtrusive. At night, I’m able to go down two floors to the basement, without turning on any lights. The motion-sensing LEDs in the ceilings switch on as I move about the house.
The Top Energy Efficient Freezers 2008
July 21, 2008 11:06 AM - , MetaEfficient
When researching energy efficient appliances, we often turn to the recommendations of the American Council for an Energy-Efficient Economy (ACEEE). The ACEEE continues to publish helpful information about all sorts of appliances, including freezers. The ninth edition of their Consumer Guide to Home Energy Savings, published in fall 2007, contains helpful information about selecting a freezer.
