Dutch unveil world's first solar-powered bicycle path

The Netherlands on Nov. 12 unveiled the world's first solar bike path, a revolutionary project to harvest the sun's energy that could eventually also be used on roads.
      
The so-called "SolaRoad" bike path is made of concrete modules each measuring 2.5 by 3.5 metres (eight by 11 feet), embedded with solar panels covered in tempered glass.
      
To help prevent accidents, the glass has been given a special non-slip surface.
      
The solar cells currently put the electricity they generate onto the national grid, but future plans include using the energy to power street lights.
      
Electric bikes and cars will one day be able to refuel using contactless charging directly from the road or bike path, said Sten de Wit, a physicist who helped develop the project.
      
"The idea is that in the Netherlands we have approximately 140,000 kilometres (87,000 miles) of road which is much bigger than all the rooftops put together," De Wit told AFP.
      
"We have 25,000 kilometres of bike paths in the Netherlands."       

"If we can integrate it in our roads then we'll have huge extra potential for generating solar electricity," he said.
      
The path has been working for 16 days, during which it generated 140 kilowatt hours of electricity, equivalent to around 140 washing machine cycles, said SolaRoad spokeswoman Jannemieke van Dieren.
      
The project has so far cost three million euros ($3.7 million), mainly for research, but SolaRoad declined to say what the cost per kilometre might be.
      
Dutch Economics Minister Henk Kamp cycled the first 70-metre (230-feet) pilot stretch of bike path on a busy provincial bicycle route north of Amsterdam on Wednesday.
