Algae to crude oil: Million-year natural process takes minutes in the lab

Process simplifies transformation of algae to oil, water and usable byproducts

RICHLAND, Wash. – Engineers have created a continuous chemical process that produces useful crude oil minutes after they pour in harvested algae — a verdant green paste with the consistency of pea soup.

The research by engineers at the Department of Energy’s Pacific Northwest National Laboratory was reported recently in the journal Algal Research. A biofuels company, Utah-based Genifuel Corp., has licensed the technology and is working with an industrial partner to build a pilot plant using the technology.

In the PNNL process, a slurry of wet algae is pumped into the front end of a chemical reactor. Once the system is up and running, out comes crude oil in less than an hour, along with water and a byproduct stream of material containing phosphorus that can be recycled to grow more algae.

Sun Screens: Saving energy in warm climates

ECOstrive – For those of you that live in warm climates (especially the sunny ones) where you use Air Conditioning to cool your house in the summer months, you probably already know how hot the inside of an unshaded window gets in the peak of the season. This is called “thermal transference”. Transferring all of that heat inside your house makes your AC work a lot harder. Solar screens are an easy way to reduce the amount of heat making its way into your house and keeping it cooler and more comfortable. Continue reading Sun Screens: Saving energy in warm climates

NEW YORK, NY – 10 May 2007: IBM (NYSE: IBM) today announced it is redirecting $1 billion per year across its businesses, mobilizing the company’s resources to dramatically increase the level of energy efficiency in IT. The plan includes new products and services for IBM and its clients to sharply reduce data center energy consumption, transforming the world’s business and public technology infrastructures into “green” data centers.

The savings are substantial — for an average 25,000 square foot data center, clients should be able to achieve 42 percent energy savings. Based on the energy mix in the US, this savings equates to 7,439 tons of carbon emissions saved per year. Continue reading IBM Unveils Plan to Combat Data Center Energy Crisis
