The Backwater DIY Electric Boat Marathon | Popular Mechanics

Who said water and electricity don’t mix? At the Wye Island Marathon, the pairing of the two is celebrated as racers push more than 23 miles into 20 mph headwinds, 2 foot waves and rough chop, propelled only by DIY battery packs that can fail at any time.

This post is an excerpt of an article from Popular Mechanics. You can read the full post on their website. Written by Tyghe Trimble.

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.

Student-Built, Hydrogen Fuel Cell-Powered Boat to Set Sail on Hudson River

Welcome to another episode of “If college students can do it, why can’t the rest of the world figure it out too?”

An enterprising and organized group of undergraduate and graduate students at Rensselaer Polytechnic Institute have fitted an old sail boat with a spiffy set of hydrogen fuel cells and plan to run the boat from Manhattan to upstate New York later this month in a “green power” tour of sorts.

I love it when college students do this kind of stuff. Seriously. If I could have stayed in college forever, I would have. Believe me, I tried.

Killer Kelp

Killer Kelp

When I was doing research on Catalina Island, there was a wanted poster hanging in the dive locker. Although, this wanted poster was not for any bank robber or bandit. This was a wanted poster for kelp. Undaria pinnatifida, an invasive species from Asia that has hitched a ride on boat’s hulls and ballast water. Also known as wakame, you may know that name as an ingredient in many Asian dishes or miso soup.

Wakame has become a large problem from New Zealand to Monterey Bay. It is an aggressive and costly intruder that takes over a habitat at the expensive of the native species. Since its discovery in San Francisco Bay, 140 lbs of the kelp have been removed from the San Francisco Marina alone. Wakame’s destructive nature has earned it a spot on the 100 of the Worlds Worst Invasive Species list.

Ship Emissions Got You Down? Look Up At SkySails

When Magellan first set out to circumnavigate the globe, he had the stars to guide him and the wind to propel him. While Magellan was killed before he circled the globe, his second-in-command Juan Sebastian Elcano finished the journey after 3 years and 1 month. For the next three hundred years, world trade and travel was accomplished solely through wind power, until the advent of the steam engine, and subsequently the internal combustion engine. But one company hopes to reignite a second Age of Sail with a simple yet effective design that will cut down on shipping costs, toxic emissions, and fuel consumption. Enter the SkySail.

Oregon Proposes $1 Billion-Plus Transportation Investment

In a sweeping proposal intended to create jobs, inject life into the state’s economy, repair infrastructure, and bring Oregon’s transportation network into the 21st century, Governor Ted Kulongoski unveiled more than $1 billion in road, rail, bridge, mass transit and port funding yesterday.

The new transportation investments would be paid for with a myriad of tax and fee hikes, including:

  • a 2-cent per gallon gas tax increase
  • doubling the vehicle titling fee to $110
  • raising the vehicle registration fee from $27 per year to $81 per year
  • creating a first-time fee of $100 for titling cars new to the state
  • raising the tobacco tax by 2½ cents

The plan also calls for borrowing $600 million and using and additional $16 million in lottery money.

Biodiesel Powered Earthrace Beats Around the World Record by 14 Days

Around the World in 60 Days

The sleek tri-hull Earthrace eco-boat, has beaten the world speed record for a powerboat to circumnavigate the globe.  The biodiesel powered craft traveled 24,000 nautical miles in 60 days, 23 hours and 49 minutes, finishing its journey by crossing the finish line in Sagunto, Spain.

That beat a record set in 1998 by the British boat, Cable and wireless Adventurer.

Earthrace Biodiesel Boat Circumnavigates Globe, Aims For World Speed Record

Earthrace biodiesel powerboat

This 100% biodiesel-powered, 78 ft wave-piercing trimaran aims to set an around-the-world speed record while maintaining a net zero carbon footprint. The Earthrace left Sagunto, Spain, on April 27, and has already made excellent time across the Atlantic, landing in Panama just 8 days later.

Inspired by the desire to “connect with people about the need to get renewable fuels into our energy mix and to inspire them to do something,” the Earthrace has already generated a whirlwind of publicity. Much of this is due to the boat’s eco-technological appeal. It’s been described as “a rally car but for oceans”, with the ability to submerge up to 23 feet underwater while powering through the ocean. The “eco-” part doesn’t just include circling the globe on 100% biodiesel. Parts of the boat are made from a hemp-based composite, bedding foams are made from canola oil, and the operation’s total carbon footprint has been balanced by purchasing carbon credits.

A Wave-Powered Boat?

wave power, sailboat, boatsThe Japanese man Kenichi Horie is sailing across the Pacific in a boat powered by. . . waves?

The boat has two fins that raise and lower with the tide, providing a petroleum- free alternative to motoring through doldrums.

Check out the full story here.

Japanese Man to “Hang 10″ in Pacific Journey with Wave-Powered Boat

boat, wave power, alternative energy There are various ways to travel the sea in style. One of the most environmentally friendly ones would certainly be using sails alone. I mean, wind is free, right?

Well, a Japanese man named Kenichi Horie is attempting to be just as environmentally friendly but without the sails.

How does he do it? With a wave-powered boat. Wave power has been discussed quite a bit recently, with a lot of applications including traditional grid energy generation. However, Kenichi is taking things to the next level by powering his ocean going vehicle with the very thing it bobs atop.
