HP environmentally friendly printer circuit
Leeds University's Seyed Bidoki was recently able to load a "standard Hewlett Packard inkjet printer with a solution of metal salts and water" and print out an actual electronic circuit. The mysterious "silver salt solution" and vitamin C mixture could be used to "pave the way for safer and cheaper electronics manufacturing," and moreover, this cheap and easy alternative should certainly be a hit with the environmentally conscience crowd.
This method utilizes a water-soluble base, which differs from the less green solvents used in polymer ink / graphite paste varieties from before, but even individuals working with the project admit that ousting the current regime will be difficult.
Still, the crew is pressing forward with this toxin-free approach, and hopes to elicit the help of "industrial jet printers" before long to speed things up.
