     the gisbornes have recently completed a twelve-day trip on their solar-powered electric boat, the loon. they traveled down the erie and oswego canals for twelve days before reaching albany, new york. monte gisbome, the captain of the loon, said that this marks the first time that anyone has traveled down american canal system using solar electric energy as the primary (主要的) fuel source.
   the tamarack lake electric boat company designed the loon. it is a boat with solar panels (太陽能板) mounted (安裝在) on its top which provide 738 watts of electricity using energy from the sun. it also has a 48 volt deep-cycle battery that has a range of thirty miles. it has a top speed of five miles per hour.
   the boat is "solar-assisted" rather than "solar-driven" because it has a battery charger (電池充電器) which is built into the boat. it can help power the boat when the solar panels do not collect enough energy.
   monte gisbome talked about the boat in an interview. "the problem with technology these days is that it produces too much heat and too little energy for motion. my boat is at least eight times more efficient than a gas-powered boat, which means that it saves me a lot of money and keeps the environment clean. even in these technologically advanced times, some of the more popular gas-powered boats are terribly inefficient, which means that they cost a lot of money to use every day, and they make the water very dirty."
   he also mentioned that the solar panels can provide the boat with about 16 km of free travel on a sunny day. "for most customers, 16 km is enough and," monte gisborne said, "even if you travel 32 km in one day, as long as you don't use it the next day, you have nothing to worry about because the battery won't run out of power."
