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.

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.

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.

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. Read the rest of this entry »

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.

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. Read the rest of this entry »
