Clean Burning Natural Gas Vehicles (NGVs) are hot commodities in some parts of the country, where fuel can sell for as low as $0.63 per gallon.
Unlike the world’s most fuel efficient car (VW’s 285 MPG bullet), the Honda Civic GX looks like a standard passenger vehicle. What makes it special is what you don’t see: tailpipe emissions that are often cleaner than ambient air.
The Civic GX is powered by compressed natural gas—methane—the simplest and cleanest-burning hydrocarbon available. With an economical 113-hp, 1.8-Liter engine, the EPA has called the Civic the “world’s cleanest internal-combustion vehicle” with 90% cleaner emissions than the average gasoline-powered car on the road in 2004.
And get this: in Utah, natural gas can be purchased for $0.63 per gallon.
General Motors announced today it would be entering into a strategic relationship with Mascoma Corp., a second-generation biofuel company with the technology to produce cellulosic ethanol from non-food sources via a single-step biochemical conversion.
The undisclosed equity share aims to contribute to joint research and development along with technology exchange, plant siting, and rapid commercialization of cellulosic ethanol technology and infrastructure. This is GM’s second investment in a cellulosic ethanol company, after announcing partnership with Coskata back in January.
As the automakers scramble to make plans for achieving 35 MPG by 2020, it seems that our suspicions that the task is entirely possible without fancy hybrids or hydrogen cars has been confirmed. The manufacturers been achieving high mileage in Europe and Japan for years now, so I expect to see it in the US eventually. Luckily, there are six exciting new technologies that are going to make it possible in the US.
These technologies are interesting because they come without the paradigm shift that seems to accompany buying a hybrid or a small economy car. Cars equipped with this green tech will be just like any other car, just more efficient.
More on the six new engine technologies after the break.

Once consigned to reading tech magazines, green entrepreneurs in the tech space now are drifting to business sites - as it should be. More and more tech sites are covering business issues and more importantly, business sites, particularly those focused on green business are delving into the technology, particularly computer technology, fields.
Green entrepreneurs of every stripe face similar business challenges.
How to write a marketing plan.
How to handle inventory.
And in a tighter money era, how to find financing.
Converting the nation’s vehicle fleet to run on 85% ethanol (Flex-Fuel) may have gotten a whole lot easier.
AAMCO, one of the world’s largest chains of automotive service centers, has started an initiative designed to promote environmental sustainability and energy efficiency across the nation.
The Eco-Green Auto Service initiative will certify automotive centers that meet a stringent set of criteria while adding services that cut emissions, improve mileage, and reduce hazardous waste associated with owning a vehicle.
AAMCO is also promoting alternative fuels by installing E85 conversion kits that allow vehicles to run on ethanol blends up to 85%. Their service centers will use kits provided by Flex Fuel US ®, called the FLEX-BOX SMART KIT™, which is the only ethanol conversion kit fleet-certified by the EPA.
Ford Motor Company will be replacing up to 40% of their petroleum-based seat cushions with a new material made from soybean oil. “Soy foam” costs roughly the same to manufacture as traditional petroleum derivatives, but requires less energy to produce and may reduce environmental impacts by 75%.
The new material was developed by Ford’s own researchers, and made its debut in the 2008 Ford Mustang. Soy foam has also already been incorporated into the seat cushions of Ford F-150 pickups, Expeditions, and Lincoln Navigator SUV’s. By the end the year, Ford says it will have 45,500 soy-foam vehicles on the road.

All work and no play makes Jack a dull boy, so goes the old adage. But in Africa, green innovations by very creative and eco-imaginative minds seem to be turning this adage around, and perhaps we will soon hear of: “All work and play combined sustains a green Africa”.
It all started with the PlayPump, the water system that is a children’s merry-go-round attached to a water pump and storage tank that featured on Ecoworldly a while ago.
A see-saw that generates electricity when played on by children? Now there is this simple looking see-saw which when played on by children in Africa, generates electricity to help power up their school. It has no name yet but if this trend continues, it looks like Africa will be one very big playground for green play, literally.
You wanna play, somebody?
While the first algae-to-biofuels facility went online today, scientists at Argonne National Labs are manipulating the photosynthetic super-organism for another use: creating hydrogen.
Algae grows prolifically in adverse conditions, and can store large amounts of oils or starches useful for making biodiesel or ethanol. But some strains also use an enzyme called hydrogenase to produce small amounts of hydrogen gas. Scientists think this is the organism’s way of getting rid of excess energy under high-light conditions.
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.
