Panasonic Hopes Its Artificial Photosynthesis System Will One Day Convert Factory Released CO2 Into Ethanol.

Watch the video. I’m not even going to try to explain how Panasonic’s Artificial Photosynthesis System works. [DigInfo]

Panasonic’s Thermoelectric Hot Water Pipes Generate 7.5 Watts Of Power Per Foot.

Panasonic is designing an improved system to generate thermoelectric power by making it more efficient. Thermoelectric power is created via temperature differences – in this case, between the hot and cold water running through your house. Attempts to generate thermoelectric power in the past have been unsuccessful due to the amount of heat lost in the process.

The video pretty much explains how Panasonic’s thermoelectric tubes work. [DigInfo]

Greenpeace Guide to Green Electronics

Greenpeace Guide to Green Electronics
The “Greenpeace Guide to Green Electronics” has been out for about a month and the latest release, timed for the CES Expo, follows the same direction as earlier releases. Gather data from publicly available sources, Corporate Responsibllity Reports etc., and put it in a USA Today’ish format that makes it easy to read. My issue with the Guide to Green Electronics is that the difference between “Partially Good” and “Partially Bad” is “Extremely Vague”. Dell Computer, for example, receives a “Partially Bad” rating of +1 even though from the information in the guide, Dell is moving in a direction of being BFR/PVC free. And is Microsoft really a bigger electronics polluter than Panasonic? You’ve seen their toilets – you be the judge.

I will always try to give Greenpeace the benefit of the doubt but it’s difficult to find value in their “Guide to Green Electronics” report. It’s based solely on publicly available information. This is not their forte and it shows. The only thing I could compare it to would be… um… if the CEA responded by rating Greenpeaces’ anti-whaling efforts based on information gleaned from the Discovery Channel.
