The Netherlands made headlines last year when it built the world's first solar road - an energy-harvesting bike path paved with glass-coated solar panels. Now, six months into the trial, engineers say the system is working even better than expected, with the 70-metre test bike path generating 3,000 kWh, or enough electricity to power a small household for a year. "If we translate this to an annual yield, we expect more than the 70kwh per square metre per year," Sten de Wit, spokesman for SolaRoad, the group behind the project, told Tarek Bazley at Al Jazeera. So just imagine the potential if we covered all our roads in the stuff. It’s this kind of thinking that got the Internet so hyped-up over Solar Roadways last year - a crowd-funded project that aimed to power the entire US with solar-covered roads. However, the Netherlands became the first country to put the idea into practice with their installation in Krommenie, a town north of Amsterdam. The solar panels used on the Dutch bike path are sandwiched between glass, silicon rubber and concrete, and are strong enough to support 12-tonne fire trucks without any damage. Each individual panel connects to smart metres, which optimise their output and feed their electricity straight into street lighting, or the grid. The engineers spent five years creating the system to be durable. "If one panel is broken or in shadow or dirt, it will only switch off that PV panel," said Jan-Hendrik Kremer, Renewable Energy Systems consultant at technology company Imtech. More than 150,000 cyclists rode over the solar panels during the trial, and so far they’ve only noticed one fault - a small section of a coating, which provided grip to the surface, has become delaminated due to temperature fluctuations. The team at SolaRoad is now working to improve this coating. "We made a set of coatings, which are robust enough to deal with the traffic loads but also give traction to the vehicles passing by," Stan Klerks, a scientist at Dutch research group TNO - the parent company, which came up with SolaRoad - told Bazley from Al Jazeera. The researchers design the panels to not only let in as much light as possible, but also to last at least 20 years - a similar lifespan to rooftop solar panels. StarryNightStudio Roosegaarde The potential is pretty huge. Not only could the roads generate enough electricity to power local households, but they can also provide some amazing lighting opportunities. Last year a solar road was installed in the Netherlands by design lab Studio Roosegaarde, which sucked up the Sun's energy during the day and then guided cyclists at night using beautiful Vincent Van Gogh 'Starry Starry Night- inspired LED lights. SolaRoad is now working with local councils around the Netherlands to try to roll the technology out in other provinces. A similar agreement has also been signed with California in the US. Bring on the future.

Just think -- the "war on terror" is 25 years old. How much clean energy could have been developed with all that money and effort? How much energy and effort have been totally wasted in the conflict? I was originally told by friends that we had to do Operation Desert Slaughter to keep gas affordable in this country. Grabbing those countries' oil has always been at least part of the deal for amerikans, and a big part of it for our so-called leaders. We're a pretty sorry case when when russkies, chinks and dotheads can outclass us so easily.
Unfathomable. The civilized peoples of the world could be living in almost literal paradise by now if not for the warmongering maniacs in our own ranks for the last 5000 years.
Political "leaders" are good at presenting a winning smile. Of little value for doing anything else. Bureaucrats they employ are not much different.
