Generator

Although many multitools pack a ton of features, some of those features often take the form of tiny, near-useless tools. The VAK6 keeps things simple with a knife, flashlight and pulse ignitor, along with an optional cranked generator for recharging.

In the 1980s, Honda turned heads with the iconic Motocompo – a fold-out scooter designed to fit snugly in the trunk of the City car. Four decades later, it could make a comeback as an EV range extender you can ride.

The "apocalypse-ready" Cybertruck Sting isn't the prettiest truck, but it promises serious off-grid capability. Along with various grades of armor, the Sting boasts Starlink internet and a jet-fuel generator to fully recharge the drive battery.

With a slogan like “The Future is Ecclectic,” we’d expect some interesting things from INNengine, a startup based in Spain. The company is showcasing a “one-stroke” engine that works as an opposed piston with a wavy twist.

Although many groups are developing power-generating "smart fabrics," the technology is often too complex to be scaled up to commercial use. Now, however, scientists have devised a method of embroidering electrical generators onto regular fabric.

Scientists working on cheap and easy-to-make electrical generators have landed upon a design that makes use of store-bought double-sided tape, and which they say can perform on par with more complex systems when it comes to producing electricity.

The new BluOasis BluMobile trailer puts deployable solar power, lithium battery storage and water-making capabilities atop a military-grade off-road trailer, giving RVers, overlanders and remote workers more off-grid autonomy. It even sleeps four.

Fusionflight has announced an 8-kW microturbine generator that weighs less than one-tenth of what an equivalent petrol generator would, and it's the size of a toolbox instead of needing its own wheels – if you can handle the epic noise levels.

Sesame Solar announced this week what it calls the world's first 100-percent renewable mobile nanogrid. Powered by a wing-like solar panel spread and green hydrogen, the modular nanogrid brings weeks of autonomous electricity where it's most needed.

While we've been hearing a lot about wearable piezoelectric devices that produce electricity from people's movements, such gadgets don't work well under certain conditions. A new bioelectric wearable, however, could excel where they falter.

The idea of using human movement to generate electricity is something we've seen applied to many areas, and scientists have now developed a highly efficient form of wooden flooring that leverages this technology to power a lamp with footsteps.

Thermoelectric generators produce an electric current through a temperature gradient. Now, engineers have created a new device that absorbs heat from the Sun on one surface and emits it from another, allowing it to generate electricity day and night.
