Woollett hasn't been able to consistently strain a fuel that is clean enough to run through his vehicles. "One time, I had to take my car in to get it cleaned out," he says, "and that cost me a couple hundred bucks."
But he's not close to giving up.
"No way," he says. "There is a little trial and error involved, but I have faith that ultimately—and very soon—I'll come up with the right mixture. A lot of this is experimental, remember. We're are on the front lines of technology."
The solar panels, on the other hand, work wonderfully—and inexpensively.
"We've been powering our home with the panels for three years," says Woollett, "and our electricity bill is, well, zero. Before that, I was paying close to $800 a year, and I'm sure it would be even more now."
The slight downside is that the Woolletts' solar panels are not generating at maximum capacity—basically because their neighbors were no more welcoming of the new technologies than Molnar's.
"They said if they could see any of it," Diane recalls, smiling, "they would shoot us."
Consequently, the Woolletts moved the panels to a place on the roof where they are hidden and perched at a 13-degree angle, rather than the optimum 30-degree angle.
"We love them, anyway," says Diane, practically meditating on the backward-spinning meter—even as her washing machine does a midday load.
"I think everybody should do this," says Joe. "It's a way of living responsibly. And cheaper."
