Gas 2.0

ABG recently reported on the fact that the new Subaru R1e has recently been spotted tooling around the streets in New York City as part of an official trial in the US, which is an extension of the 40 (soon to be 100) car trial currently taking placing in Japan.

In light of this new development, I thought it would be prudent to show off some of the most exciting features of theR1e, beginning with the fact that it is an all electric version of a production car made by major manufacturers to be affordable and useful to average citizens (though these needs might be a bit different depending on the market).

It’s exciting enough in and of itself to see a major initiative from a major manufacturer (yeah yeah, the Volt, sure), but this car is pretty sweet on its own.

Recently Darin at EcoModder dug up a Car and Driver article from the middle of the US gas crisis in 1974. It may be a little dated, but considering recent gas price increases these kinds of DIY hacks are becoming relevant once again.

The material prices may be a little different, the cars may be a lot different, but surprisingly little has changed in terms of fuel economy and gas prices. The Car and Driver article is interesting because not only is it old, but it’s still relevant today.

As someone who has been around ecomodding for a while, I can vouch for the efficacy of many of these modifications, and have done some of them myself. So, if you’re really interested, I encourage you to get out there and do some yourself. None of them are engine modifications, or particularly difficult, so don’t feel intimidated by them. Some of the biggest fuel economy gains can come through aerodynamics and rolling resistance modifications.

Read about the modifications after the break.

In January, USDA researchers completed a five-year evaluation of another biofuel feedstock with the potential to make a serious dent in US petroleum usage. In the largest study to date, switchgrass has been shown to produce 540% more energy than was used to grow, harvest, and process it into cellulosic ethanol, while reducing greenhouse-gas (GHG) emissions by 94% when compared to gasoline.

USDA geneticist Ken Vogel commented that the study demonstrates switchgrass’s potential to be a major renewable biofuel that reduces GHGs and could “potentially displace 30 percent of current U.S. petroleum consumption.” Read the rest of this entry »

Is it going to come down to a choice between eating or driving? Is that what are future holds? If it does, it looks like the driving contingent may win (or in other words many others will lose…or starve). That’s a distorted overview of last night’s EcoNow presentation that highlighted the current and future state of biofuel. Actually I like the term that one of the speakers Eric Holt-Giménez used – “agrofuels” rather than “biofuels” because “bio” means “life” which certainly doesn’t represent these alt fuels.

The event held in Berkeley (where else?) gave Tad Patzek, Professor of Geoengineering at UC Berkeley, Miguel Altieri, Professor of Agroecology at UC Berkeley, Eric Holt-Giménez, Executive Director of Food First/Institute for Food and Development Policy, and Judith Mayer, Project Coordinator of the Borneo Project a chance to educate or frighten the audience into what’s happening with agrofuels, whether it’s ethanol, B20, or something else that makes our cars go.

Plug-in Hybrids (PHEVs) have taken some undeserved heat lately, with the recent hullabaloo over their potential to drain U.S. water supplies. But as some readers pointed out, it all depends when you charge them.

This week’s report from Oak Ridge National Laboratory, which evaluated the impact of a substantial increase in PHEV ownership, found that nighttime charging of PHEV’s would not increase electricity demand over baseline levels. In other words, no (or very few) new power plants would need to be constructed if plug-in owners only charged their vehicles at night.

Not everyone is waiting until 2010 to get their first plug-in hybrid. As I reported previously, Hybrids Plus out of Boulder, CO, is offering conversions for the Toyota Prius and Ford Escape hybrids, turning them into 100 MPG+ superstars.

I’ve collected a little more background on Prius hybrid hacks, and a few more resources. Check out this video, which should give you a good feeling for what getting 100 MPG would be like: Read the rest of this entry »

French analysts have concluded that the wild popularity of gasoline-hybrid electric vehicles in the United States could potentially hinder development of more sustainable and advanced green vehicles:

Hybrid electric vehicles that run on both conventional gasoline and stored electricity can be no more than a stop gap until more sustainable technology is developed, according to researchers in France. They suggest that the adoption of HEVs might even slow development of more sustainable fuel-cell powered electric vehicles.

The researchers go on to argue that the “misinformed craze” for hybrids in the U.S. is creating a situation where every manufacturer must include hybrid technology in their portfolio in order to stay afloat: Read the rest of this entry »

[UPDATE 9/15/09]: Volkswagen’s Diesel-Hybrid L1 Concept Gets 170 MPG, Available by 2013

Welcome Google search visitors: This is just one of many articles produced here on a daily basis on Gas 2.0. If you find this post interesting, sign up for our RSS feed and stay up to date.

This is what a team of engineers can do when challenged to push the limits of fuel efficiency and technology. You may have already heard of VW’s 1-liter car, but take a closer look. It’s a sports-economy concept car produced a few years ago by VW engineers, to answer one big question: could they build a car that consumes less than 3 liters of fuel for every 100 km traveled?

It turns out they could, but they didn’t stop there. Instead, VW blew by that goal to create a car that uses only 1 liter of fuel for every 100 km. That’s 285 MPG.

For under $30,000, you will soon be able to buy an electric car with a 120 mile range, or a plug-in hybrid that gets 300 miles-per-gallon.

Sound like a fantasy, but this one could be coming to a dealer near you. Slated for release in late 2008, the company Aptera will be offering the initial limited release of their fully electric model Aptera Typ1, and the 300 mpg plug-in will follow in 2009.

While plug-in hybrids offer great increases in fuel efficiency, they may come at a surprising cost: water. A recent study from Environmental Science & Technology found that plug-ins require the consumption of 3 times more water, and the withdrawal of 17 times more water, than their gasoline counterparts. As Popular Mechanics pointed out last week:

A 30-mile commute in a gasoline-powered car would require the withdrawal of 18.9 gallons of water… The same commute in a plug-in hybrid electric vehicle (PHEV), meanwhile, would take a whopping 318 gallons…

So what accounts for the increase in water usage? PHEV’s don’t require water directly, but the power plants that power them do:

Any power plant that runs steam turbines uses water, whether fired by coal, natural gas, or nuclear energy, says King, a mechanical engineer at the Bureau of Economic Geology at UT. Many plants consume water by running it through cooling towers where it evaporates away. Plants can also tie up water resources via withdrawal, in which plants recycle water that is drawn from a reservoir.

Just to mix things up a bit, take a look at this car from the 2008 Eco-Marathon, registering at a whopping 7,148 MPG (via Autopia):

Looking like one of those space caskets from Star Trek, the single-seat racer you see to the left, constructed by a team from the French technical school St. Joseph La Joliverie and dubbed the Microjoule, traveled an amazing 7,148 miles on a single gallon of fuel (in other words, almost ten miles per teaspoon).

55 MPG isn’t good enough for you? Then try adding a plug to your hybrid.

The electric-car company ZAP, in conjunction with Hybrids Plus, has announced it will offer plug-in hybrid conversions for the Toyota Prius and the Ford Escape Hybrid:

Hybrid vehicles retrofitted with systems from Hybrids Plus of Boulder, Colorado can achieve a significantly greater fuel economy. In tests these systems increased hybrid fuel economy up to 120 miles per gallon in the city and up to 90 mpg on the highway. The cost for the conversion ranges from $24,000 to $36,000 depending on the vehicle and size of battery pack.

Have you ever wondered what amazing new technology would beat hybrids in the “green” category? Plug-ins, electric cars, fuel cells, carbon-capture cars? Turns out the next step forward could be a step backward.

Enter the Toyota iQ: small, sleek, roomy, and possibly with lower CO2 emissions than Toyota’s ubiquitous Prius. Why do I call the iQ both a step forward and a step backward? It’s because the iQ isn’t a hybrid, plug-in hybrid, or anything else that’s been hyped up in the news recently. The iQ represents simplicity and good design — showing that a small car with some innovation can still go pretty far.

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.

How much does business-as-usual cost? This morning, Green Car Congress reported that the US is projected to pay $440 billion for imported petroleum in 2008:

The increase to the estimated $440 billion for 2008 is based on an average $90 per barrel crude oil price for the year. In 2002, before the current bull market for oil began, US oil imports cost less than $103 billion. The preliminary figures for last year came to some $327 billion.

With little prospect for cheaper gas prices in the future, any decrease in the US export bill will have to come from a reduction in petroleum usage.

Which brings to mind two important questions:

1. What percentage of our Gross Domestic Product will the US have to export before things start to change dramatically?
2. Where is all this money going, anyway?
