Riverwood
The ride out, as can be expected during the year's first snow, was atrocious. People don't understand how to drive around bicycles as it is, and when you combine the general lack of long-term memory when it comes to driving on snow (for some folks, the first snow of the year is always the first time they've driven on it, no matter how Michigan winters they've endured).
A couple hundred feet away from the clubhouse, I could see the reason for my trip. Sticking out from above the clubhouse was a windmill, its blades spinning in the wind.
The story was ostensibly about the windmill that the place uses to help generate electricity, but I found that the most interesting elements were actually the way the place is heated, the mechanic who keeps the place up, and the potential for Segway use next summer.
First things first ... the windmill. Three blades, made of wood and coated with copper. I've always heard that one of the knocks on windmills is that they're difficult to maintain, and suffer from equipment failures. Not this one. The reason, I guess, is that back when they decided to build it, they invested in good equipment from the get-go. Every few years, they need to change the six quarts of oil, and the maintenance guy recently stripped down the blades pretty well and recoated them with copper. A few years back, based on the numbers they gave me, and because they got some tax incentives when they installed it, the thing finally paid itself off and now represents a positive investment.
What really caught my attention was how Dick Figg, the business owner, heats his bowling alley.
The entire time we're walking around his place, he's shutting doors that are open. "I try to be green by shutting doors," he kept saying. The obvious first thing on his mind, it was obvious, was efficient use of energy. A good way to go. Once, he pointed to an open door, and said, that's a stick of wood right there.
What's that mean? Very simple. The golf course, like almost every Michigan golf course, has a lot of trees on it. Enough that every year a couple fall over in big storms. Limbs fall down. Trees get old or diseased and die.
So, Riverwood takes its dead trees, cuts them up, and then burns them for heat. Not a wood stove, but to heat water in a boiler -- between 600-800 gallons -- which is circulated through insulated pipes (so as not to lose heat) to big radiators in heat transfer units. A fan blows across the radiators, which disperse heat into the bowling alley concourse. When the place is open and full, body heat from active patrons adds a couple of degrees and the place stays a cozy 70 degrees all winter from burning fallen trees. In fact, scattered around his property, he said he's got about three years worth of wood.
He said this'll pay for itself in less than four years.
The guy who maintains both is an expert on green energy, but because he genuinely appears interested in finding new ways to power things ... not because of political belief. Back in the 70s, he built an electric car and also windmills to provide power for it -- wind-powered transportation, if you will.
Next up? Segways for the golf course, which the literature claims require about a 10th the electricity as a single-rider golf cart (or one-fifth the electricity of a two-rider golf cart).
