Green Options

Hand-built, eco-modified, and wood-powered cars raced across the Bay State this weekend driving 100 miles on just a single gallon of fuel. Aptly named the One Gallon Challenge, the event was part of a four-day long festival in Boston that celebrated clean technologies. Welcome to GreenFest 2009!

Car companies like Tesla, Toyota and Nissan are all scrambling for a piece of the EV market. Heck, even cities like San Francisco and Portland want some.  But they all just got pwned by these kids. These vehicles run on everything from solar to soy!

But they don’t. It costs between $12,500 to $22,500 to convert a gasoline-powered car to natural gas in an autoshop. That old gas hog just can’t be greened up for cheap. Now. But it could be.

Natural gas conversions don’t not have to cost that much: there is no technological problem driving what it truly needs to cost for auto mechanics to make a living at it. The true cost is only a few hundred dollars in parts and labor. The reason for this incredible difference is exceedingly interesting, as Robert Rapier notes in a well researched piece over at The Oil Drum on  the feasibility of switching from Gasoline to Natural Gas.

Not only is the reason interesting, but embedded in the reason is the simple way to solve it. Then converting cars to Natural Gas could cost what it actually costs; just a few hundred dollars - an hour’s work; a few parts.

We could cut our very hoggy national carbon footprint by switching to natural gas which we now have an abundant supply of if these new natural gas reserve numbers are even remotely accurate. So we could drive  less hoggy on somewhat cleaner fuel. And - (supposedly) in the carpool lane

The VP of The Auto Channel claims that this cost is unnecessary:

It’s hard being an environmental celebrity, especially when you are Royal too. People want to see you, but that can mean racking up a lot of carbon miles.

So Prince Charles had his Aston Martin converted to run on bio-ethanol made from aged English wine, and his Audi, Jaguar, and Range Rover all run on what the English call old cooking fat.

In the US we call this reused cooking oil because that’s much hipper and greener sounding, and marketing is everything.

So now Prince Charles is driven in the royal Jaguar that runs on homemade biodiesel and, for a little variety; in the Land Rover or the Audi, in a carbon conscious fashion.

But what about his airplane travel? Well…

Don’t laugh.

This started as just another ho-hum, run-of-the-mill, zero emissions, homemade solar powered EV.

But, sensibly, noting the enormous contribution of the wind turbine in the “snout” 400 watts at 28 MPH, night or day! Joe Rush, the inventor plans on adding a second wind turbine! This would bring the total on-board electricity supply  to nearly 1 KW. Well, at least when it’s traveling at 28 mph, it would.

Perhaps following the findings of that Federal study which recently found that wind power is the second most cost-effective investment for Federal renewable energy dollars, right behind geothermal power Joe Rush is simply utilizing the free energy generated by simply being a moving vehicle: wind, from which he creates the first wind powered EV.

Unfettered by the slow-moving decision-making procedures of giant auto companies (some of which will no doubt still be trying to sell us gas guzzlers even while our poor planet enters it’s second Eocene) Joe is able to nimbly head back to the drawing board for this radical revision. A second wind turbine will be added.

But where?

17-year-old Andrew Loader from Lindsborg, Kansas has amazed his parents by building his very own electric car (Video) from nothing more than a clapped-out Ford Escort, some batteries and an old forklift motor.

Tired of paying last summer’s high gas prices, Andrew decided to take matters into his own hands and build the street-legal vehicle after researching the idea on the internet.

To begin with, Mom and Dad were less than impressed with the scheme. “Mom told me not to, and dad did too. I had to write a letter to Mom and her friend convinced her not to ground me or kill me,” said the industrious teenager.

A Ford Motor Company engineer has built a 3-wheel motorbike capable of getting 125 mpg. 

The fuel economy expert crafted the vehicle at his home shop in Belleville, MI. It’s a street legal, two-passenger, 3-wheel motorbike that is made from aircraft materials. Oh, and it is capable of a top speed of over 100 mph.

As we’ve reported over the last few weeks, sometimes electric-powered drag racing can break boundaries in exciting new ways. The electric motorbike that rockets from 0-60mph in under a second, and a 1972 Datsun that just happens to be the world’s (second) fastest elecric car spring to mind.

Sometimes though, EV face-offs on the drag track are just well…daft. Check out this hilarious footage of the recent Alternative Fuel Race 2009 in the UK featuring electric skateboards and battery-powered dune buggies.

While we wait to see if General Motors will go banko come June 1, Raser Technologies is hoping to change our minds about one of GM’s most iconic offerings: the Humvee.

During the upcoming 2009 SAE World Congress (Detroit, April 20 - 24) the company plans to unveil a Hummer H3 Range-Extended Electric Vehicle (ReEV) prototype. The vehicle is designed, first and foremost, as a purely electric vehicle with a drive train similar to the Voltec system in the Chevrolet Volt.

“We are resurrecting the Hummer,” David West, vice president of marketing for Raser Technologies said, adding that “It’s like a Volt on steroids.”

There are quite a few three-wheelers these days: Aptera, Myers Motors and ZAP! Motors. And while those companies seem to be blocked from government funding, it isn’t stopping designers like 22-year-old Alex Hodge from New Zealand from churning out kickass mods like the Hawk.

The Hawk concept is part fighter jet, part sports car, and looks like it’s balls-out fun! The concept is built around the 999cc Honda RC51 V-twin engine has 10,000 rpm, 120 hp and a top speed of 144 mph.

Out on the dragstrip, one hardly expects the car kicking ass and taking names to be an old ‘72 Datsun 1200. Especially when the losers are driving BMWs, Corvettes and Ferraris. But those guys didn’t get pwned by any ol’ Datsun…this one’s electric!

It seems a bit like a paradox. Drag racing is flame-dipped muscle cars with bikini-clad hood ornaments spread over the hood. Electric cars, not so much.
