Why Thinking of Nothing Can Be So Tiring: Brain Wolfs Energy to Stop Thinking
From ScienceDaily: “Mathematicians at Case Western Reserve University … [have] found that just as thinking burns energy, stopping a thought burns energy — like stopping a truck on a downhill slope.”
John Doerr on the Bloom Energy Launch: “This Is Like The Google IPO”
Techcrunch describes Bloom Energy’s technology, which was unveiled today at a Silicon Valley press event: “Each fuel cell, which is made from sand essentially (zirconium oxide), is a square wafer about the size of a CD box. Each wafer can produce about 25 watts of energy, enough to power a lightbulb. Stack them together and you get a box that could power a house. Group them into larger units, and you get enough energy to power a building or an entire campus. [Bloom Energy’s founder and CEO] calls them energy servers because they are modular like servers in a data center. Need more energy? Add more boxes.” The downside: not yet cost effective for homes.
