Gas 2.0

I’m eagerly awaiting the 4-door, family-sized EV sedan rumored to be in the pipeline from the Canadian-based ZENN Motor Company (they already make a great 2-door model that’s even affordable to us non-celebrity types, picture above). I’d like to avoid going to the gas station at all when going to an Energy Fair or Green Festival. While our VW Jetta TDI gets more than 40 mpg, these days the cost for diesel (and biodiesel when I can get it) is quite a bit more than gasoline, and rising faster than gas.

For now, we’re moving around locally in a funky-looking, all-electric CitiCar, made in 1974. Our CitiCar is restored to roughly original condition (except for the wear and tear on the body itself) with the expert help of our neighbor who found two more after we found ours. It’s hard to go anywhere without people cutting me off — not out of rage — but curiosity or with a smile on their face. Sometimes getting a “head turner” doesn’t need to come at a huge price.

The Cafe Racer Truck Runs on 100% Recycled Coffee Grounds

A commenter on Ben’s wood-powered truck post pointed us to a similar car hack. The truck above is also powered by a wood gas generator, except this one runs on coffee grounds. The Cafe Racer is a 1975 GMC pickup that essentially burns up used coffee to create a combustible gas. The gas is filtered on its way to the engine and, Viola, a caffeine-powered truck.

Homemade ethanol guru Floyd S. Butterfield and Silicon Valley entrepreneur and innovator Thomas J. Quinn want to see you making ethanol in your backyard. Their creation, called the E-Fuel 100 MicroFueler, is a stacked washer-dryer sized reactor that can convert sugar into ethanol for (they claim) $1.00 per gallon.

Before you get too excited, please note that the unit is probably too expensive for your next block party, unless you’ve got an extra $9,995 lying around somewhere. Fortunately, state and Federal tax credits can halve this, but that still keeps it out of the price range of the average American. Read the rest of this entry »

Increased world demand for grains and vegetable oils due to population growth (esp. in China and India), the weak dollar, agricultural production problems around the world, and $100/barrel oil are some of the driving factors accounting for increasing food prices.

After covering 22 of the most popular myths about biodiesel, I realized I’d only given lip service to a major issue: increasing food prices. In Myth #2, I mentioned that the goal of biodiesel production is to move away from food-based feedstocks.

But until that happens, the question remains: if I use biodiesel made from soybeans right now, am I contributing to the larger problem of increasing commodity prices and starving poor people? Read the rest of this entry »

Most of us are at least vaguely familiar with biodiesel, but how much do we really know?

While biodiesel is easily the most popular alternative fuel available, it’s commonly misunderstood or misrepresented by inaccurate information. Since the most frequent question I get is, “So what exactly is biodiesel, anyway?“, I decided to write a tome covering all the basics—a one stop shop for all your biodiesel- related questions.

It’s been exactly one year since I published the first Biodiesel Mythbuster on GreenOptions.com, and its popularity made a sequel inevitable. By way of a short introduction, here’s what I wrote last year: Read the rest of this entry »

If you can’t buy the car you want, then build it.

Gregg Abott (aka Gadget) custom-converts cars for a living, but instead of tricking out cars to run on biodiesel or get better mileage, he’s hacking them to run on electricity. He’s the owner of Left Coast Electric, a Santa Monica based company with a simple philosophy:

“…if electric cars are going to make a difference, a lot of people have to drive them. They have to be made affordable.”

Which means these guys aren’t putting out $100K Tesla Roadsters, but are converting older models to have the same functionality:

So instead of building cars from the ground up, Gadget and his business partner, Roger Wilson, convert existing cars or shells of cars into electric vehicles by supplying or outfitting them with pre-configured kits loaded with everything an electric car needs except a new motor.

Admittedly, this isn’t for the faint of heart. Each kit costs $10,000 and requires the tenacity to dive into major auto electrical work. But if this type of conversion seems like a daunting task, Left Coast Electric will do the work for you—for $17,000 that is, including parts—which means that for the price of a Prius, your old car could be fully electric.

For $30,000, they’ll even convert your Hummer.

Trying to learn how to make biodiesel, or interested in seeing how it’s done? It always helps to get a visual, and you may not be aware that there are currently enough biodiesel videos on YouTube to develop an entire college course on the subject. I’ve thrown out a representative sample, just to give you an idea of what’s available.

While this is a good general introduction to homebrewing biodiesel, I have to repeat the disclaimer I made earlier (see 6 Ways To Find And Use Biodiesel Anywhere - Part II): before attempting this on your own it’s important to do your homework. Don’t trust it just because you’ve seen someone do it. Most of these videos don’t discuss the specifics of making biodiesel, and for that I would recommend a solid resource (also see the link just above): Biodiesel, Basics And Beyond: A Comprehensive Guide to Production And Use for the Home And Farm.

You’ll notice a lot of these videos utilize a homemade biodiesel reactor called the “appleseed” reactor. This is the simplest and cheapest way to build a biodiesel processing facility in your garage. The plans for it can be found here.

Number 1: Guy Makes Biodiesel In His Kitchen

I can’t believe his mother lets him do this in the kitchen, and where are his gloves?! (I have a particular affiliation for the video, though, since I had the same old truck.)

The first part of this guide should give you some good resources for finding biodiesel at home and on the road. But don’t think you have to rely on retail biodiesel to get by. Homemade (aka “homebrew”) biodiesel may be available in your area, or you may be inclined to make your own.

While fuel quality obtained by this method can vary considerably, it’s still possible (even likely) to get fuel that meets national standards. That being said, you may have to get your hands dirty, and this will require a bit more research than finding a local biodiesel pump.

Options 1-3 of this guide are located here.

4. Biodiesel Coops: Discount Fuel At A Price

Another option for the intrepid is to join hands with other biodiesel enthusiasts and participate in making the fuel yourself. Biodiesel co-ops pool resources, equipment, and know-how, and may be the best way to learn to make biodiesel. While you don’t necessarily have to get your hands dirty to participate in a co-op, it can be satisfying work, builds community, and lies at the heart of the biodiesel movement.

Looking to find a source of biodiesel? Perhaps you followed my previous post, 7 Steps To Buying A Diesel, or maybe you already have a vehicle and feel it’s time to boycott OPEC oil. Either way, this guide will help you figure out how to get from A to B exclusively on biodiesel. Part II (options 4-6) of this post can be found here.

Remember that biodiesel can be used in any diesel engine (warranty issues aside) without modification. The only conversion necessary is where you decide to fill up, and that’s what this guide is intended to supplement. One caveat: be advised that biodiesel use can be tricky in cold weather, and depending on location and season you may have to drop to a 50% or even 20% biodiesel blend (more on that later). Without further ado:

1. At Home: Find Biodiesel At Retail Gas Stations

Without your knowledge, a local retail station may already have converted one of their pumps to some blend of biodiesel. The most common blend is B20 (20% biodiesel, 80% diesel), but don’t be surprised to see “biodiesel stations” with a lowly 5% blend (B5). (Stations now commonly offer B5 to confer lubricity lost by the introduction of Ultra Low Sulfur Diesel - ULSD.)

If you’re lucky, you may even find a B100 pump nearby, but there are other ways to get pure (aka neat) biodiesel (see below). You can find a list of retail biodiesel stations at both the National Biodiesel Board’s website, and NearBio.com:

Things have changed a lot since I was driving across the country, or occasionally flying to a new destination and renting a car. I knew there’d be a gas station up ahead, and had a pretty good idea what prices would be when I stopped at the pump.

My, how things have changed. There are more fuel choices, and a trip to the MapQuest Gas Prices website will show you what I mean. Read the rest of this entry »
