7 Car Mods That Get 100 MPG Or More

Jerry James Stone — Mon, 24 Aug 2009 16:41:10 +0000

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!

Garage-Built Car Gets 105 MPG, Cost $2,500 To Build

Frustrated with the price of filling up his Toyota, Jory Squibb built the Moonbeam. It has been to the Altwheels Festival in Boston twice and has traveled over 10,000 miles. It is powered by a 150 cc gas engine and carries two passengers “if they are on good terms,” he says.

15 Students Turn A ‘76 Porsche Into A Fully Electric Car

The car was converted into a electric vehicle using 18 U-Charge® XP Lithium Phosphate batteries…and 15 MIT students. The electric version has similar driving performance to the original vehicle, with the added advantage of regenerative braking. It has a range of about 100 miles on a full charge.

Hybrid Trike Uses Diesel, Electric, And Pedal-Power

The Tri-Hybrid Stealth is a two seat, 3-wheeled vehicle that is powered by a diesel engine, an electric motor and the driver’s legs. For reals. It’s also the first hybrid trike to offer exclusive hand controls and an automated extendable seat for handicapped drivers.

Biomass Powered Truck Runs On Wood And Cardboard

Dave Nichols , a 42-year-old home builder and auto shop owner from eastern Connecticut, modified his 1989 Ford F-150 pickup truck to run on wood, leaves, cardboard and other “biomass” with a fuel system that he says expels virtually no pollution. Dave’s entry was the only truck in the competition.

Diesel-Powered Trike Built Almost Entirely Of Aluminum

The super-light Roopod, built by an Industrial Designer from western Massachusetts, is powered by a 2-cylinder diesel engine. Inspiration for the car came when he realized his V-dub weighed 3,000 pounds. “For every gallon of gas that I put in, 90 percent of it is being used to drive the car, and 10 percent to drive me, and that’s just stupid,’’ he said.

Three-Wheeled Green Grand Prix Winner

Built by Bill Buchholz, the Dirigo is a three-wheeled diesel two passenger vehicle that has a top speed of 72mph and does 0-60 about 30 seconds. It recently won its class in the Green Grand Prix, averaging 90 MPG. Um, can you tell it was designed by boat builders?

Gaia, The 300 MPG Trike

Built by Ken Fry, he says the vehicle will deliver 300 mpge with an electric range of about 30 miles and a top-speed of 90 mph. How? Well the car only weighs 540 pounds.

The One-Gallon Challenge; 100 miles on a gallon of gas

Christopher DeMorro — Mon, 17 Aug 2009 18:46:16 +0000

Global warming. Climate change. The greatest threat to continued human survival. The rhetoric these days can be awfully scary regarding new energy and oil. Sometimes it feels like we’ve all been doomed already by a hyper-active media always looking for the “next big story” to terrify us with. But I don’t really take anything seriously, so I am always on the lookout for a fun twist on a real problem.

What could be fun about climate change, you ask? Well, besides the fact that my home might end up as beach front property one day if we don’t mend our sins, how about a race? One that challenges contestants to go 100 miles on a single gallon of gas? That is the goal of the One-Gallon Challenge, where six contestants and their very different vehicles have to make the journey from Greenfield, MA to Boston in three hours using as little fuel as possible.

Virent Energy Producing Gasoline From Raw Plant Material - Update

Anthony Cefali — Thu, 19 Feb 2009 21:09:05 +0000

It’s almost been a year since Virent Energy partnered up with Shell to advance their biogasoline synthesis technology, known as bioforming.

I’ve been curious about their progress, and recently listened to a lecture given at the University of Wisconsin-Madison by Virent researcher Paul Blommel on the bioforming process.

During bioforming, sugars and polymers are rearranged into alkanes (biogasoline) that can be used for fuel in combustion engines. The gasoline produced is of a higher volatility and better production efficiency than corn ethanol.

Virent is still in the developmental stages of gasoline production. Their patented aqueous phase reforming (APR) technology and BioForming process is currently producing a liter per day of pure gasoline from plant material. For now they are mainly using simple sugars found in plants, but plan to tap into the more woody lignocellulose too.

After the lecture, I had a chance to talk with Blommel in depth. Read more of that conversation after the jump.
