PetroSun has announced it will begin operation of its commercial algae-to-biofuels facility on April 1st, 2008.
The facility, located in Rio Hondo Texas, will produce an estimated 4.4 million gallons of algal oil and 110 million lbs. of biomass per year off a series of saltwater ponds spanning 1,100 acres. Twenty of those acres will be reserved for the experimental production of a renewable JP8 jet-fuel.
Gordon LeBlanc, Jr., CEO of PetroSun, had this to say:
“Our business model has been focused on proving the commercial feasibility of the firms’ algae-to-biofuels technology during the past eighteen months. Whether we have arrived at this point in time by a superior technological approach, sheer luck or a redneck can-do attitude, the fact remains that microalgae can outperform the current feedstocks utilized for conversion to biodiesel and ethanol, yet do not impact the consumable food markets or fresh water resources.”
In January, Scientific American writers unleashed an ambitious plan to halt global warming, eliminate our dependence on petroleum and the substantial trade deficit, boost the economy and create 3 million jobs, and brighten the dismal forecasts for the mid twenty-first century.
The plan is conceptually simple but would be substantial to implement:
- Construct a 30,000 square mile array of solar panels in the Southwest,
- along with concentrated solar power arrays and,
- a massive direct-current power transmission backbone to distribute electricity throughout the country.
- Excess power produced by the photovoltaic arrays would be distributed and stored as compressed air in below-ground caverns.
Development of such a system could provide almost three-quarters of the nation’s electricity by 2050.

Since its inception in 1992, the ENERGY STAR program, a joint program run by the Environmental Protection Agency and the US Department of Energy, has sought to protect the environment by promoting energy efficiency. Starting with personal computers and monitors, ENERGY STAR established energy usage guidelines that set the bar for energy conservation. Over the years the ENERGY STAR program has brought just about anything that uses energy or water under its umbrella, saving an estimated $14 billion in energy costs in 1996. LEED for Homes and the NAHB’s Model Green Building Guidelines both encourage green home builders to use ENERGY STAR rated appliances. For those seeking additional credits - and energy savings - both green building programs encourage the use of very efficient clothes washers. But what exactly is a very efficient clothes washer?
A very efficient clothes washer saves both water and energy. Water Factor (WF) measures the number of gallons per cycle per cubic foot that the washer uses. In order to qualify as a very efficient clothes washer, it must have a WF of less than 5.5. To put that number into perspective, washers that have a WF of 8, the maximum for an ENERGY STAR labeled clothes washer, use up to 10,000 gallons of water a year. One of Asko’s UltraCare clothes washers boasts of a WF of 3.4, using under 3,000 gallons of water a year. Granted, at 1.9 cubic feet the Asko model is quite small, but if water efficiency is the goal, Asko sets the standard.

Take 8,000 ice barges; mount two industrial ice cannons on each; add a windmill for power; let sit in the arctic with cannons blasting.
This might be the secret tech-heavy recipe for pepping up the faltering Atlantic ocean currents that heat Europe. So says industrial engineer, Peter Flynn of the University of Alberta. The cost: $50 billion USD. Ouch. Perhaps an ounce of prevention really is worth a pound of cure.

Imagine what cart corals at the supermarket would look like if shopping carts didn’t nest together. Imagine what the entryway of the supermarket would look like if shopping baskets didn’t stack. This would be poor spatial planning on the designers part. Next, image what a parking lot could look like if our cars stacked? We all of the sudden will have a plethora of open […]
A research team with the CSIRO (Commonwealth Scientific and Industrial Research Organization) in Australia is working on a project to integrate energy-generating materials into our clothing. By simply collecting the energy in our movement, vibrations, and friction, our clothing could create enough juice to power up our mobile phone, mp3 player, etc. The Australian Defense Department awarded the team of researchers a $4.4 million grant to deem the technology feasible.

Renewable energy is big, big, big: Josh just wrote about the world’s largest wind farm possibly going up in South Dakota (yahoo!), California could see the world’s largest solar power plant, and now Singapore is in the foray with landing the largest solar manufacturing facility the world’s ever seen.
A Norwegian company called Renewable Energy Corporation (REC) will build the complex, which will be completed in different stages to incorporate wafer,

Minneapolis Mayor R.T. Rybak may be the first mayor in the nation to drive a plug-in hybrid vehicle as his official city car.
Since he was first elected in 2002, Mayor Rybak’s official car has been a Toyota Prius. But the dramatically superior gas mileage of a plug-in hybrid vehicle prompted him to make the switch: he had his hybrid converted to a plug-in hybrid electric vehicle, from which he expects to get

The world of journalistic reporting is a funny one, with revisions and corrections sometimes making a lot of work moot. According to Apple, this may be the case for a piece I wrote on the iPhone taking a beating from Greenpeace. So, in an effort to keep our reporting fair and balanced (oh gosh, now I sound like I work for Fox) here’s the other side to that article.
The article in question
