Hail, Hydra…Light? You too might be singing this portable lighting product’s praises if you find yourself off the grid without a battery to your name. Designed with campers, boaters, and outdoor revelers in mind, Hydra-Light’s range of flashlights, lanterns, and energy cells harness salt and water as its power source. Several models even come with a USB port, so you can juice up your cellphone or smart device at the same time. Each Hydra-Light features an energy cell that comprises a carbon-based membrane and a replaceable metal-alloy cylinder known as a PowerRod. When an electrolyte like saltwater—or just regular table salt and water—is added to the mix, the two elements react to generate a current. Related: Light-powered device can purify air and generate clean energy This reaction continues until the PowerRod is exhausted to a sliver, leaving only “harmless mineral sediment” behind, per the Australia-based manufacturer. “When the rod has become very thin, it is removed and a new one is inserted—which takes just seconds—making the cell like new and ready to continue generating power,” Hydra-Light said. “All that’s needed during the lifetime of each PowerRod is a periodic rinsing out of the mineral sediment and refilling with fresh saltwater. Unlike conventional batteries, the power output remains constant and does not decline over the lifetime of the rods.” Hydra-Light claims that a single PowerRod provides more than 250 hours of continuous power, which is equal to the output of about 85 standard AA batteries but at a “fraction of the cost.” (Each Hydra-Light product includes a preinstalled PowerRod.) It’s still salad days for the company yet, but the technology is nothing if not promising. For the 1.3 billion people around the world who live without electricity, Hydra-Light could prove life-changing. For the rest of us, it’s several more sets of single-use batteries we don’t have to toss out. Americans purchase—and presumably dispose of—more than 3 billion dry cell batteries every year to power our various gadgets and gizmos, according to the U.S. Environmental Protection Agency . Hail, Hydra-Light indeed. + Hydra-Light [Via Digital Trends ]

Tom Raffield’s Beautiful Flux Pendant Lights are Made From Sustainably Sourced Oak

Comments Off on Tom Raffield’s Beautiful Flux Pendant Lights are Made From Sustainably Sourced Oak

Award-winning lighting designer Tom Raffield ‘s new Flux Light was inspired by the flow of the tides and the form of the waves. A central cylinder at the top of the light conceals the bulb, whilst fourteen strips of wood flow out and down to form a shape that is symmetrical, yet embraces the soft wave of contours flowing around the bottom edge of the shade. Hand-crafted in Tom’s woodland workshop, each individual wooden strip is made up of three laminated lengths of wood and held in place at the top by flush-cut oak pegs that form a design feature in themselves. The interior is lined with two strips of ash that turns a beautiful golden color when the light is on, reflecting the light out. The outside is made of classic, sustainably sourced oak, giving a gentle tone whilst allowing glimpses of the lighter wood lining the inside. + Tom Raffield The article above was submitted to us by an Inhabitat reader.
