Innovative solar cycle path breaks in poor weather conditions

Only open for a month, solar cycle path in the Netherlands has already broken down

A solar cycle path in the Netherlands designed to convert sunlight into energy has broken.

The path in Krommenie, Northern Holland, designed as an experiment to see if more road surfaces could be used to produce energy, has failed thanks to poor weather which has caused the top layer to detach and break off.

The pilot path was only opened last month, and is around 70m long with a planned 30m extension by 2016. It will be extensively tested over the next three years, precisely to see if problems like these materialise, according to NOS.

The damaged area, around one metre of path, has been turned off, but the rest of the path remains open.

Called SolaRoad, the path comprises modules measuring 2.5 metres by 3.5 metres.

Those in one direction of travel have solar panels beneath a 1 centimetre thick layer of tempered glass, said to be able to withstand the weight of a lorry.

The modules in the other direction don’t have the solar panels, and are being used to test a variety of surfaces.

SolaRoad has been developed by TNO, the Province of North Holland, Ooms Civiel and Imtech Traffic&Infra.

The provincial government met half of the €3 million cost of the project, which in its current form can supply enough electricity to meet the requirements of three homes.

Eventually, SolaRoad could power street lighting and traffic systems, electric bikes and, and once deployed on roads used by motor traffic, electric cars.

Current testing is aimed at addressing issues such as its performance in a live situation, the amount of energy it produces, and how cyclists experience riding on the surface.

Prior to its deployment, it was tested in a laboratory to ensure it meets relevant safety requirements for road surfaces.

Wouldn't this path need to be jet washed regularly or do they simply expect low efficiency? I'd be more interested to know what cost they thought this could be mass-produced for, prototype costs are not the cost that matters.

The individual slab size looks a bit big,

Most if not all cycle paths in the Netherlands are cleaned frequently by little street cleaning vehicles; much like the ones on UK roads.

"Part" of a path designed to be an experimental pilot project has broken, proving that there is a longevity issue with that part of the technology.

There's no point doing a pilot where nothing breaks, all you learn is that you've overspecified everything  1

Aye gazza, it's much better in the UK eh?

To you I guess sarcasm is just a 7 letter word beginning with S.

My earlier comment may have been a bit subtle for some

Just want to get this right, the pilot path is around 70m long and the damaged area, around one metre of path. Humm, so around 1.4% of an experiment path has failed and this is some sort of a disaster?

If they knew it would work perfectly from the start, they wouldn't be bothering with an experiment... must be a really slow news day.

Who said it's a disaster? The article clearly says "It will be extensively tested over the next three years, precisely to see if problems like these materialise, according to NOS"

Bloody dutch can't even get infra right. Paint doesn't break
