Newark (California): Forget microchips. Silicon Valley sees a profitable future in the humble brick thanks to a low-energy production process that illustrates the greening of the US technology capital. Brick maker Calstar Products is backed by venture capitalists whose vision is to create buildings less expensively and in a way that saves energy. “We think it is time for a second industrial revolution,” said Paul Holland, a partner at Foundation Capital, which invested $7 million in Calstar. EnerTech Capital led another round that raised $8 million for the business. Currently about 40% of US energy use goes toward the heating, cooling and general operation of buildings. Silicon Valley is finding high-tech ways to make ageold materials, pursuing carbon dioxide-eating concrete, windows that insulate better than walls, and wood substitutes. The field is still new. Venture investments in green buildings have waxed and waned with the recession, but involved 45 deals worth about $350 million the past year, according to Cleantech Group LLC. Bricks have been made pretty much the same way for 3,000 years, until Calstar’s scientists came up with their new technique, said Chief Executive Michael Kane. Ordinary bricks are fired for 24 hours at 1,100°C as part of a process that can last a week, while Calstar bricks are baked at temperatures below 100°C and take only 10 hours from start to finish, Kane said. Lower energy costs mean higher profit, allowing the company to pay for its research and compete against large companies that have economies of scale. The new bricks — which the Brick Industry Association says are not actually bricks — will sell for the same price as traditional claybased ones.
