Computer Chips Made of Wood Promise Greener Electronics

alphadogg writes: Researchers in the U.S. and China have developed semiconductor chips that are almost entirely made out of a wood-derived material. In addition to being biodegradable, the cost of production is much less than conventional semiconductors. According to the NetworkWorld report: "The researchers used a cellulose material for the substrate of the chip, which is the part that supports the active semiconductor layer. Taken from cellulose, a naturally abundant substance used to make paper, cellulose nanofibril (CNF) is a flexible, transparent and sturdy material with suitable electrical properties. That makes CNF better than alternative chip designs using natural materials such as paper and silk, they argue in a paper published in the journal Nature Communications."

    Not actually true. As part owner of a tree farm we've looked into carbon credits, etc. CO2 sequestration is highest in the first few years of growth and then gradually tapers off. You probably get more CO2 sequestered in the first 20 years than the next 80.

    For the highest amount of CO2 sequestration you need the plant matter to fall into an anaerobic bog and slowly sink into the ground as new stuff lands on top. After a few hundred million years, an advanced society then digs it as coal and oil and burns it, dumping all the carbon back into the atmosphere.

    There's a huge amount of stored carbon in the ground. It's only a problem when you burn it. Burn current plant matter and and you're only returning the carbon that came from the air recently, not the carbon that's been saved up for millions of years.

    I read the title and was immediately "No."

    Seriously, news like these are not news and misleading titles and vague speculation does not make it any more credible.
