Hydra-Light is a groundbreaking technology that uses water to create electricity

coffee brew pipe outdoor retailer awardsFor this summer’s Outdoor Retailer show in Salt Lake City, Digital Trends teamed up with The Manual to crown the greatest outdoor gear as our Best Of Show winners, along with two brand new awards going to the most innovative products. Head on over to The Manual to see the complete Outdoor Retailer Awards.

As a host of established and startup companies took to the Outdoor Retailer showroom floor this summer intent on debuting the the latest products, perhaps no brand unveiled anything quite as innovative as the Hydra-Light. Using an imaginative new energy cell technology called Hydra Cell, Hydra-Light flashlights actually rely upon water — yes, water — to produce light. An innovation in every sense of the word, the groundbreaking Hydra-Light tech was impossible to ignore as a Digital Trends Innovation Award winner.

Debuted by the similarly named Australian company, Hydra Light, this inventive new approach to flashlight technology should prove an absolute game changer. Simply dunking a HydraCell in water for roughly 10 to 15 seconds produces more than 100 hours of power for a lantern or flashlight, and provides incredibly easy access to electricity. Though a single exposure to water won’t power the cell to its capacity, it can subsequently be dunked to replenish the electrical current.

By developing a cell that utilizes water as a hydration system, the team at Hydra Light found a way to produce steady electrical currents by way of liquid. To top it off, Hydra Light offers a range of lanterns, flashlights, and power packs compatible with a variety of Hyrda Cell sizes and variations, with each toting the same water-activated tech but different applications.

It’s easy to chalk up something this unique as a gimmick. But Hydra Light didn’t take to the Outdoor Retailer show to simply talk about its invention — it gave showgoers a firsthand look at the tech in action. Across the Media Preview event and on the main showroom floor, Hydra Light treated passersby to what seemed like a magic trick. A booth outfitted with buckets of water, several large HydraCells, and samples of the company’s Mini-Light, Hydra Light dunked cell after cell in water, which accomplished the dual feat of powering the flashlight and dropping jaws to the floor.

What helps make the tech even more fascinating rests not just with its ability to serve as a versatile camp light, but also with its inherently positive benefit on the environment and the impact it could have on developing countries. Hydra Light reports that, according to the EPA, more than 3 billion batteries are thrown out annually in the United States. (It’s easy to recycle batteries, actually.) And since the only requirement for a Hydra-Light flashlight is water — no matter how clean or dirty it is — developing countries should have consistent access to a convenient form of electricity.

There’s no denying the advantages inherent in Hydra Light’s Hydra Cell technology, making it the perfect recipient of a Digital Trends’ Outdoor Retailer Innovation Award.

This trail-tested, road ready Aventon e-bike is $200 off — We gave it 4.5 stars
Aventon Ramblas eMTB e-bike for trail and off-road rides

At the risk of repeating myself, we are rather fond of Aventon e-bikes here at Digital Trends. They tend to review favorably because of how much value they offer. Take the Ramblas eMTB e-bike, for instance. We gave it four and a half stars in our review back in August. Resident reviewer and e-bike expert, Bruce Brown, praised it for its "strong hardtail" frame, excellent mid-drive torque, strong stopping power, smooth ride experience, and competitive pricing. The latter is a real highlight, but get this, it's also on sale right now for $200 off. So, that competitive pricing is even more enticing. Normally $2,899, it's down to $2,699 thanks to a big sale, saving you $200. Check out that sale for yourself, otherwise let's discuss why this is such a great e-bike, especially if you like trail riding.

Mod Bikes has introduced the Mod Easy Sidecar Sahara, a limited-edition sidecar-style cargo e-bike modeled on the 1940s BMW R75 Sahara motorcycle. On November 9, 2024, Mod will exhibit the Sidecar Sahara at the Electrify Expo at the Circuit of the Americas racetrack in Austin, Texas.
Mod does sidecars

The BMW R 75 Sahara, which inspired the limited-edition e-bike, is a highly collectible motorcycle. Mod Bikes is one of the few e-bike manufacturers that sells e-bikes with sidecars in the U.S., along with other styles. The versatile Easy Sidecar models transform in just a few minutes from a sidecar e-bike to a standard, two-wheel e-bike. However, the sidecar configuration is fun for carrying pets, children, small adults, and groceries or other cargo.
