Visit To An Efficient Winebar

I don’t think I would have ever discovered this winebar, had I not been led to it, through the labyrinthine streets of Arlington, by Chantrea, who is the originator of what I have to call a noetic zymurgy. I followed Chantrea through the avenues, and into a restaurant. I don’t recall which one, but I ducked inside, and we both …

Efficient: Books That Explain Train Travel In North America

Train travel is one of the most efficient forms of transportation. However, in North America, traveling by rail is not particularly systematic or comprehensive. It’s difficult to get an overview of what’s available. Thankfully, there are several good books on North American train travel, which I read recently. Here’s a brief review:

The 2009 Jetta TDI: A Clean Diesel Car

The new 2009 Jetta TDI is an efficient vehicle– this quiet-running, diesel-powered car has a cleaner tailpipe than most cars on the road. The Jetta uses a technology called “clean diesel” which actually lives up its name pretty well. While test driving this car, I found out that 97% of highway diesel fuel pumps are now dispensing Ultra Low Sulfur …

ASUS Introduces Bamboo-Cased Computers

Bamboo is an ideal material to fashion into gadgets — it’s tough but lightweight, and it wears well. I also find it much more pleasing to the eye than plastic. But few bamboo-clad electronics have made it into mass production yet. One exception is ASUS’s bamboo-cased version of its U2E notebook which is now available (currently only in Asia). ASUS …

Netgear didn’t get much of a mention in our recent post “The Greenest Routers of 2008“. But now the company has released two green routers — the Netgear WNR2000 router, and its DSL modem-equipped DGN2000. Both these routers comes with EnergyStar-rated power supplies, and they come in new packages made with 80 percent recycled content.

The Greenest Audio Systems Of 2009

This has been a breakthrough year for green electronics, but audio equipment is lagging behind a bit. As you’ll soon discover in our review below, there’s only a smattering of products that are Energy Star certified. Fewer still are those products certified to be free of toxic materials, or packaged in green manner. Perhaps audio manufacturers need to take a …

The Greenest Routers Of 2008

Networking routers are on their way to becoming standard household appliances. They are typically turned on 24 hours a day, so it’s good to see that they are becoming much greener of late. Small changes in the efficiency of appliances can lead big savings, when millions of units are being sold. For example, Linksys estimates that the improved energy efficiency …

Efficient Use Of Solar LED Bricks

Looks good! It’s a large-scale installation of Solar LED bricks. I couldn’t identify the location, but the bricks are Meteor Solar LED pavers. Solar bricks are self-contained — during they day they charge via the sun, and turn on automatically at night.
