OSHW – Open Source Hardware

I support the Open Source Hardware Definition v1.0

A cool new logo has been defined for Open Source Hardware (OSHW).

Here are the principles of what is being attempted in open source hardware (from the site):

Open source hardware is hardware whose design is made publicly available so that anyone can study, modify, distribute, make, and sell the design or hardware based on that design. The hardware’s source, the design from which it is made, is available in the preferred format for making modifications to it.  Ideally, open source hardware uses readily-available components and materials, standard processes, open infrastructure, unrestricted content, and open-source design tools to maximize the ability of individuals to make and use hardware. Open source hardware gives people the freedom to control their technology while sharing knowledge and encouraging commerce through the open exchange of designs.

Bay Area Companies – Alt Energy Management

I’m looking at companies in the Bay Area that are involved in alternative energy products.  My initial search indicates that most companies are involved in commercial buildings and larger projects.  Some are installers, most are sales organization.

My interest is to find a local (East Bay) organization that develops software for residential energy monitoring and management.  Hopefully I can find some meaningful work.

Dafur Stove

Small Darfur Stove

I love this kind of appropriate technology.  It is a wood burning stove that uses aout 1/4 of the wood that the usual “3 stone” fires traditionally use.

They cost about $20 in order to insure they have “value” over scrap metal.
