What am I missing here?

So there I was looking through my bicycle newsgroup alerts and saw a hit at alt.energy.homepower for a solar-powered bicycle. Since it's an open forum and I'm tired and irriated, this was the most diplomatic thing I could write:

Solar energy has a lot to recommend but I am skeptical of this application. Isn't the point of a bicycle that the rider expends the energy? Riding a bike that weighs 75 pounds would be like riding an anvil. I'm all for being chintzy with fossil fuels but it seems to [me] this vehicle sacrifices efficiency in many ways for the sake of being solar powered. Though admirable intentions are at work here I think someone missed the point.

Less diplomatically I have to ask two questions: what are they thinking and how fucking lazy do you have to be?

Is this really necessary?

One of my favorite generic irritated questions to ask is, "How fuckin' lazy do you have to be?" Granted, I'm extremely grateful that I don't have to grow my own wheat, mill it, keep a yeast colony growing and cut my own firewood, among other things, to make the bread for my peanut butter sandwiches (or, for that matter, shepherd my own peanuts from seed to lunch). But for instance, as much as I love my car, it irked me that the model only came with power windows. How much effort does it take for someone to roll down the windows him- or herself? Same with television remotes. After all, I can get up and use the switch on the television. It is not an imposition. So when I saw this article, I had to wonder if someone had missed the point. Oh yeah, one more thing: we all drive stick in this house. It's just not that hard.
