World's first Solar-powered bike lane in the Netherlands

Here is some pedal power. You've heard about the idea of solar roadways which has been around for some time, but how about solar bike paths?

That is an idea that the Dutch are already putting into use with the 70-metre SolaRoad, billed as a world's first. RenewableEnergyWorld highlights the €3 million ($3.74 mil) path, which powers street lights and houses and features solar cells under a layer of tempered glass.

The surface of the road has been treated with a special non-adhesive coating

If you ask me, I'd say this is not a showcase of energy or resources efficiency, but this is an idea that might bring about some interesting results; we'll see.

An insightful comment from a reader read as follow:
"2000 cyclists over crystalline silicon panels? Let me get this right. Its more or less the same as 2000 leaves of shade over a rooftop panel? Am I right? I think your road's angle is not the only obstacle. Hope you also got some good termo conduction underneath those panels, for my guess is that they will run hotter, further dropping output. You should rather have roofed the pathway with the panels, shade for the cyclists, as well as an umbrella for rain." - PJ Van Staden, REW magazine.

The trees, when fully grown, could reduce the energy production further.

The bike road would be very useful to commuters and school children and could be a cool part of their daily commute. Approximately 2,000 cyclists are expected to use it on an average day.

The road, named by the Netherlands Organization for Applied Scientific Research (TNO) as SolaRoad, is made up of rows of crystalline silicon solar cells, which were embedded into the concrete of the path and covered with a translucent layer of tempered glass.

Since the path cannot be adjusted to the position of the sun, the panels will generate approximately 30% less energy than those placed on roofs. However, the road is tilted slightly to aid water run-off and achieve a better angle to the sun and its creators expect to generate more energy as the path is extended to 100 metres in 2016.
