Top Gear is one of my all-time favorite shows. It never ceases to provide laughs and good entertainment while simultaneously managing to actually deliver useful content as well. My only gripe with it is that here in the States, we are always at least one season behind. So, while season 14 starts up on BBC in Britain, we’ll be lucky if we see the start of season 13 by February on BBC America.

That lag especially sucks right now because in episode two of season 14, which just aired in Europe, the Top Gear crew has built themselves a “car to save the world”—the Hammerhead Eagle i-Thrust. Due to the fact that BBC in Britain restricts video viewing from their website to Europeans, I can only bring you a mish mash of bits and pieces of the episode from youtube… but even without the full episode, there are plenty of laughs to be had.

Cheers and enjoy.

At the 8 ½-mile mark, Jim Campbell is at the head of the pack, in control of the race. The two-time defending champion has every reason to be confident—he knows the course inside and out, he owns the most time-tested vehicle and he still has a few tricks to pull out, including a parasail, which on this windy day could be a potent weapon. But when he grabs his remote control to adjust the speed, Campbell, his boat and its cargo—400 pounds of lead-acid batteries—suddenly stop.

“I think my nylon gear picked up static when rubbing against the plastic hull of the canoe and my electronics died,” he says. Campbell does the only thing he can—he whips out his emergency jumpers and charges 12 volts back into both of his motors. Then he adjusts his speed, dropping from about 4 knots (4.5 mph) to just less than 3 knots (3.3 mph). The race is no longer a sure win.

Texas Teen Buys Car Off eBay, Makes It Electric

Luke Laborde turned a 32 mpg gas-burning Bradley GT II kit car into a fully electric ride for just about $10,000. The ride, which was purchased off eBay, has eight 80-pound batteries throughout including where the gas tank used to be. The car gets 40 miles on a full charge.

Student Built Race Car Is Powered By Soybeans

Five kids from West Philly’s high school auto shop class, ex-gang members and high school dropouts built this soybean-powered race car. The car gets 50+ mpg and goes from 0 to 60 in just 4 seconds! But the real win here is how the experience impacted these kids. One of the few still in high school, Kosi Harmon, went from getting D’s to being a straight-A student.

8th Grader Builds Solar-Powered Bike With GPS, iPod Dock

Eighth-grader David S. Dixon built this street-legal quadricycle powered by a solar-charged electric motor. The bike not only carries his dog and three friends, but it has also has an iPod dock and GPS. Ya, it’s that cool!

16 Year Old Converts 1988 Mazda Truck To A Plugin EV

Andrew Angelloti, after saving up $6,000 as a part time lifeguard, converted his very own truck to be a plug-in. Using 20 flooded lead acid batteries to create 120 volts and a 60 HP electric motor, the truck hits a top speed of 55 mph and has range of 40 miles. Best part, he blogs about it so others can mod their cars. You can check out his blog here.

15 Year Old Builds Air-Powered Ride Back In 1989

This air-powered car was covered by KODE Channel 12 of Joplin, MO back in 1989. You can tell by VHS-to-YouTube quality of the video. The idea was pitched to car companies but largely ignored.

Alaskan Teen Converts 1971 VW Super Beetle To Electric Car

While some VW enthusiasts are still waiting for the car company to tap the electric car market (one of those being me), senior Bart Grabman has beat them to the punch. Whether or not Bart can see Russia from his house, he has my vote! Though…can I get mine in one of these?

Who needs a gas station to fill your tank with ethanol? Not you. GreenHouse has just announced the E-Fuel MicroFueler, a portable in-home micro-refinery system that turns organic waste into ethanol. The first installation of the E-Fuel MicroFueler was in the home of none other than basketball great Shaquille O’Neal, who lives in Pacific Palisades a subdivision in LA.

The E-Fuel MicroFueler coverts the organic waste into ethanol for about two-thirds the cost of gasoline. The final product is E100 (100 percent ethanol) which burns cleaner emitting significantly less emissions into the air. The only vehicles designed to run on E100 are the IndyCars which in 2007 became the first motorsports league to sanction a renewable fuel.

Robert Riley’s XR3 kit car is an amazing three-wheeled plug-in diesel hybrid. The trike gets a jaw dropping 225mpg on combined diesel-electric power and 125mpg when using only the 23hp diesel engine.

And hey, it kinda looks like that Back to the Future car!

Introduced back in June of 2008, the two-passenger car was designed so it can be assembled using readily available parts. Fully constructed, the car weighs in at 1480 pounds and has top speed of 80mph. And while you can only get 40 miles out of its li-ion battery pack, it can be plugged into any standard wall socket.

For all intents and purposes, the automobile has remained largely unchanged in the past 100 years ever since the first Ford Model T started rolling off of assembly lines. Four wheels, an engine, transmission, and as the old saying goes, if it ain’t broke, don’t fix it. But with summer around the corner, so are high gas prices (which have shot up 20% in the month of May alone) and some people are taking another approach to personal mobility, such as an 8th grade project dubbed the Solar Human Hybrid Vehicle.

Jeremy Clarkson, the outspoken host of Britain’s Top Gear auto show, made a spectacle of racing a Prius vs. a BMW M3, in which the latter recieved better gas mileage. His point was that is isn’t what you drive, but how you drive. Nothing emphasizes this idea more than the Aerocivic, a simple yet highly publicized Civic whose owner, Mike Turner, utilized basic hypermilling techniques such as coasting down hills and shutting off his engine at stop lights to maximize fuel usage. He then took his very basic car a step further by applying an aerodynamic body kit to reduce drag at high speeds, and now he is using the power of the Interweb to give further insight into the how and why of his car, the Aerocivic.

Jungle Motors is already the largest electric vehicle conversion shop in Orange County, California. They can take virtually any car and convert it to all-electric, but specialize in converting old Porsches and PT Cruisers. They’ve actually been converting Priuses into plug-in hybrids for a while using lead-acid batteries. That’s old hat at this point.

A modern team of Italian researchers has uncovered a device invented by fellow Italian G.D. Botto in 1833 that can be used to generate hydrogen with inexpensive, everyday parts. By reflecting sunlight from two parabolic mirrors onto a hollow tube wrapped in metal and filled with water, the device generates enough electricity to produce hydrogen through electrolysis. Theoretically, the device is so simple that anybody could build it in their garage.

A Texas-based company has announced the “world’s first mini-refinery” for consumer use that can produce both ethanol and biodiesel from the same small machine at the same time. It’s capable of generating up to 120 gallons per day of ethanol and 450 gallons per day of biodiesel.

Consisting of two pieces of equipment — an ethanol boiler and the mini-refinery — the whole system can fit into an area of less than 30 square feet with 8 feet of clearance and is completely automated.

Prices for regular diesel have been historically high nationwide, and all over the U.S. people are turning to backyard biodiesel as a way to make cheap fuel — a fairly straightforward process that can be accomplished for less than $1/gal.

One of the most copious sources of inedible oil to make biodiesel is the nasty, used fryer grease leftover from commercial kitchens — and what cheaper way to obtain it than stealing?

It’s early in the pre-dawn dark hours of the morning. A group of Northern California pseudohippies just finished a game of Zonk — or rather, the game just stopped because somebody quoted a line from Harold and Kumar Go to White Castle and everybody forgot what they were doing.

Yet, by a stroke of luck, the conversation about Harold and Kumar reminds the group of their real reason for staying up so late. They pack into a truck and head down to the local fast food joint looking to load up — but it’s not the food they’re loading up on, it’s the nasty, half-rotted, leftover fryer grease.

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.

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.

Engine Repower is a new service that gives car owners the option of replacing their old, worn out engine with a rebuilt engine of the same vintage instead of simply buying a new car or repairing specific problems. When a first saw this page, I was very interested, as I am a proponent of keeping your car as long as possible to reduce wasteful manufacturing processes, even in the face of promises of lower emissions made by newer cars.

Teams from around the world are gearing up for the Automotive X Prize, a competition that will award part of $10 million to the team that builds the cleanest production-ready 100 MPGe (mile per gallon equivalent) vehicle.

This isn’t a race centered on space-age concept cars that will never see a US highway, but aims to jump-start the auto industry with revolutionary, super-efficient vehicles that consumers will actually want to buy. Entries must be ready for production and have a business plan outlining how they’ll be brought to market. They’ll also be judged on safety, cost, and features.

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.
