Solar-powered streetlights spin and move to chase the sun

We see plenty of solar-powered products today, ranging from simple lamps to complicated electronics. But despite the sustainability benefits these offer, there’s no escaping the fact that they do need to soak up the rays to actually work. That’s not much of a problem if the devices have large batteries that can be used when the sun is out, but not so much for smaller objects that have to be smarter in how they get some sunlight. The sun, unfortunately, never stays still, and other atmospheric conditions could make an area less exposed from time to time. To help alleviate that problem, this design concept for solar-powered street lamps takes inspiration from Mother Nature in order to seek out the sun where it shines the brightest.

Designer: VANTOT

When people talk about street lights, most will probably imagine lamps on top of posts. These lighting fixtures are designed to be stationary in order to be reliable landmarks as well as to make them more convenient to reach and maintain. That restriction, however, might pose a problem for solar-powered street lamps because they will always be at the mercy of the sun’s location. When clouds cast shadows or buildings rise to block the sun, these lamps might lose their one and only source of power.

The Sunseeker is an experimental solution to that problem that uproots street lights and sets them on a chain rather than on a post. This frees the hanging lights from staying in one spot and lets them move freely along the chain. It might be a strange capability, but it makes sense when you consider that the light sensors on each lamp actually detect where sunlight shines strongest and then move or turn the lamp’s solar panel to face that direction.

It’s definitely an odd feature, but one that can actually be seen in nature. The sunflower, for example, is famous for how it always faces the sun, a trait that is even more important for solar-powered devices. In this manner, the Sunseeker lights can move where the sun is, ensuring that it will always be at peak performance when the day star finally sets.

In addition to implementing a critical function, this sun-seeking behavior puts a playful spin on the lamps, pun intended. Crowds can be amazed and entertained as the circular panels slowly move and spin to match the direction of the sun. But even when they’re staying still, the lamps exude a character that is almost otherworldly, especially with how they look like a fleet of tiny UFOs lining up in the night sky.

Tvilight Street Lamps Only Light up If Someone’s Around

The streets are often empty in the dead of night, but they’re all still well-lit anyway. That makes sense, because I’d want it to be well-lit in case I find myself walking home in the wee hours of the morning. It’s definitely a huge waste of energy though, because no one’s around to actually make use of that light.

A neat concept that aims to solve this problem is Tvilight. Basically, these streetlamps will only light up when someone is around. If its wireless sensors can’t detect any people or vehicles nearby, then the lamps will switch to its dim light mode. The sensors are able to detect how fast a person or object is approaching, so it can flick the lights on quickly as needed.

The Tvilight is expected to cut typical carbon dioxide emissions by 80% and reduce maintenance costs by half. It’s definitely got huge potential for use in streets all over the world. What do you think?

ARM forms UK group to foster an Internet of Things, put 50 billion devices online by 2020

ARM forms UK group to foster an Internet of Things, put 50 billion devices online by 2020

ARM isn't content with dominating the mobile space. It's been by the far the most vocal about an Internet of Things where everything is connected -- and to make that happen, it just established an industry forum in the UK that it hopes will establish common ground for all those internet-linked light bulbs, refrigerators and thermostats. Home energy firm Alertme, cloud-aware sensing outfit AquaMW, lighting maker EnLight and white space wireless guru Neul will start meeting with ARM from August 24th onwards to hash out our automated, eco-friendly future. There's a certain urgency in this for the chip designer: it expects 50 billion devices on the grid by 2020. With IDC estimating a billion new connected devices just in 2011, the clock on that connected device transition is ticking very loudly.
