Powered by the Sun: Solar-Powered Roads

solar_roadsCurrently, there are nearly 30,000 square kilometers (18,000 square miles) of roads in the United States. And by some estimates, there are also as many as 2 billion parking spaces. That works out to some 50,000 square kilometers (31,000 square miles) of usable surface that is just soaking up sun all day long. So why not put it to use generating solar power? That’s the question a entrepreneurial couple named Scott and Julie Brusaw asked themselves, and then proceeded to launch a solar startup named Solar Roadways to see it through.

Their concept for a solar road surface has the potential to produce more renewable energy than the entire country uses. In fact, they’ve actually already developed a working prototype that’s been installed in a parking lot, and they’re now crowdsourcing funds in order to tweak the design and move towards production. Once completed, they hope to re-pave the country with custom, glass-covered solar panels that are strong enough to drive on while generating enough power to perform a range of functions.

solar_roads1These include providing lighting through a series of LEDs that make road lines and signs that help reduce nighttime accidents. Embedded heating elements also melt ice and snow and are ideal for winter conditions. The surface could also be used to charge electric vehicles as oppose to fossil fuels, and future technology could even allow for charging whilst driving via mutual induction panels. Amazingly, the team also found that car headlights can produce energy in the panels, so cars driving around at night would be producing some electricity.

Since 2006, Solar Roadways has designed and developed hexagonal glass solar panels studded with LED lights that could be installed on a variety of surfaces such as roads, pavements and playgrounds. These panels would more than pay for themselves and would benefit both businesses and homeowners as the energy generated from driveways and parking lots could be used to power buildings, and any excess can be sold back to the grid.

solar_roads3A glass surface may sound fragile, but the prototypes have been extensively tested and were found to be able to easily withstand cars, fully loaded trucks, and even 250,000-pound oil drilling equipment. The textured surface means it isn’t slippery, and since it can self-power small heaters inside to melt ice in winter, it’s supposedly safer than an ordinary road. As Scott Brusaw put it:

You first mention glass, people think of your kitchen window. But think of bulletproof glass or bomb resistant glass. You can make it any way you want. Basically bulletproof glass is several sheets of tempered glass laminated together. That’s what we have, only our glass is a half inch thick, and tempered, and laminated.

Recycled materials can also be used to produce the panels; the prototypes were constructed using 10% recycled glass. All of the panels will be wired up, so faults can be easily detected and repaired. They team have also designed a place to stash power cables, called “Cable Corridors”, which would allow easy access by utility workers. Furthermore, they also believe that these corridors could be used to house fiber optic cables for high-speed internet.

solar_roads2Obviously, this project isn’t going to be cheap, but Solar Roadways has already surpassed their goal of raising $1 million on their indiegogo page (they have managed to raise a total of $1,265,994 as of this articles publication). With this money, they will now be able to hire engineers, make final modifications, and move from prototype to production. They hope to begin installing projects at the end of the year, but a significantly larger amount of money would be required if they were to try to cover all the roads in the US!

However, given the increasing demand for solar technology and the numerous ways it can help to reduce our impact on the environment, it would not be surprising to see companies similar to Solar Roadways emerge in the next few years. It would also not be surprising to see a great deal of towns, municipalities and entire countries to start investing in the technology in the near future to meet their existing and projected power needs. After all, what is better than cheap, abundant, and renewable energy that pretty much provides itself?

The Future is Here: Smarty Rings

smarty-ringsOkay, its not exactly here yet, but the implications of this idea could be a game changer. It’s known as the Smarty Ring, a crowdfunded idea being advertised on Indiegogo by a group of inventors in Chennai, India. And at its core is a waterproof, stainless steel band that will feature an LED screen and connect to your phone via Bluetooth 4.0 wireless technology.

For some time now, the Chennai-based group has been the source of some controversy, due mainly to the fact that they have no working prototypes of the ring, but also because they have not identified themselves beyond giving their location. They also freely admit that the photos of the Smarty Ring on Indiegogo and on their website are photoshopped.

smarty-rings1Surprisingly, this has not prevented them from being able to mount their campaign to raise money for its development. While the crowdfunding site Kickstarter has rules requiring creators to be clear about the state of a project’s development and show a prototype “demonstrating the product’s current functionality,” Indiegogo has no such rules.

However, this has not stopped their campaign – which officially closed at 11:00 am ET on Dec.11th, 2013 – from raising a total of $299,349 from their original goal of $40,000. Numerous blueprints of what the watch would look like, including detailed images of its electronics, are also available on their campaign page. What’s more, the group is still taking advanced orders and offering discount pricing to anyone who orders one before Dec.30th.

smarty-rings3Also, the group has become much less clandestine since the campaign closed. In response to questions, group spokesperson Karthik said the project was founded by Chennai-based mechatronics engineer Ashok Kumar, and that their team of inventors includes electronic and computer engineers with experience in robotics and nanotechnology.

Ultimately, the goal of the project was to create a high-tech gadget that would also double as “high-end fashion jewelry,” according to an email to CBC News from the team’s marketing director, Karthik, who did not give his last name. The group also claims on their website that the average smartphone user checks their phone every six minutes, and promises to make that unnecessary, saving time and the battery life of the smartphone.

smarty-rings4According to the The Smarty Ring’s site, the features are to include:

  • A clock with stop watch, timer and alarm
  • Notifications of calls, text and email messages, and social networking updates from services such as Facebook, Twitter, and Skype
  • Phone controls that let users accept or reject incoming calls, make outgoing calls to preset numbers, and control music or the phone’s camera
  • A phone tracking feature that beeps when your phone gets more than nine meters away from you
  • The ring charges wirelessly and its creators guarantee 24 hours of battery life

The Smarty Ring team says the retail price for the device will be $275, but backers and people who preorder before Dec.30th will be able to get one at the reduced price of $175. They estimate that delivery will begin sometime in April of 2014. They are also offering cheaper versions that include only the tracking feature or the clock and tracking features.

smarty-rings5Needless to say, if this is a scam, it is clearly a well-thought out and elaborate one. Not only is the idea of a smart ring that can connect wirelessly to other devices and do the job of a smartphone entirely within the bounds of current and developing technology, its a very cool idea. But if it is in fact real, its realization could mean a new wave of innovation and design for the smart devices market.

Currently, designers and developers are working towards the creation of smartwatches, smartphones, tablets and phablets that are not only smaller and much thinner, but also flexible and transparent. An even smaller device, such as a ring or bracelet, that can do the same job but be far more ergonomic, may be just what the market ordered!

And in the meantime, be sure to enjoy this promotional video from the Smarty Ring website. And be sure to check out their website and determine for yourself if they are liars, inventors, or just plain dreamers:
