This solar powered electric scooter is a cooler sibling of the Motocompo moped

Posted on by

We’ve seen Motocompo knock-offs, personal electric commuters and cargo bikes that would put a four-wheeler to shame. This one by San Francisco-based company Otherlab is radically different though. Dubbed Lightfoot, the electric cargo scooter has built-in solar panels to employ limitless solar power to charge the in-built battery.

The electric scooter’s 120W solar panels sandwich the considerably large 45.2 L storage compartment which is big enough to store essentials like a backpack, grocery bags, books, or any other essentials. One of these panels is hinged to allow access to the inside compartment. This space is also used to conceal the UL-certified 1.1 kWh battery and the 600W on-board charger.

Designer: Otherlab

The padded seat on the bike is comfortable enough for a single rider, however, if a pillion needs to take the ride home that option is also open as the bike has footplates too. Lightfoot is powered by a couple of 750W brushless DC motors that generate 90Nm peak torque and hurl it to a top speed of 20 miles per hour. Whether it can scoot around medium-grade hilly terrain is still not clear, but based on specifications alone it should be able to do that. The motors are plugged into the 1.1kWh battery capable of having a 37-mile range on a single charge.

The solar panels charge up in broad sunlight to add around 3 miles with an hour of charge, and 18 miles on a full sunny day.  People who are heavy users will mostly rely on the wall plug charging option and the solar charge will be a bonus. The bike will be a good option for users who will use it for short trips to the supermarket or local metro station.

Otherlab has kept in mind the maintenance and repairability of the scooter at any service center or local garage since it comes with off-the-shelf components making up the functional parts of the ride. Another set of deal-making features are the one-year complete bike guarantee and two-year mechanical guarantee. To top it off you’ll also get the “ironclad buy-back guarantee” as the company is promising a buy-back option if the user is not satisfied with LIghtfoot. Interestingly the goofy little scooter will be available to buy in the US from January for a price of $4,995. We can expect it to make an appearance at CES 2025 in Las Vegas.

Chinese researchers test smallest solar-powered drone that can fly as long as it gets sunlight

Posted on by

A major problem with tiny flying drones, referred to as micro aerial vehicles (MAVs), is that they cannot fly for a very long duration. Especially the MAVs weighing under 10 grams, as such micro vehicles can only stay airborne for about 10 minutes. Using sunlight as a constant power source could provide a solution to keep such bird-sized drones afloat and flying longer.

However, it’s not as simple as sticking a solar panel on the wings. Traditional propulsion systems used in micro aerial vehicles aren’t very efficient at making appropriate use of generated solar power. Moreover, these tiny drones can’t carry much payload, making them inconsistent and unworthy in support operations, search, and rescue.

Designer: Beihang University

The CoulombFly, a small, ultra-efficient drone powered by static electricity was introduced as a solution to the abovementioned problem by scientists at Beihang University in Beijing, China. The super-small drone uses a special propulsion system that can lift to a decent height while using very little power for the same. The vehicle itself weighs just 4.21 grams – which is extremely lightweight – has a wingspan of 20 cm, and can carry a payload of roughly 1.59 g.

According to the researchers, CoulombFly is about ten times smaller and weighs 1/600th the weight of the previous, smallest and lightest solar-powered aerial vehicle out there. Dubbed then as the smallest and lightest solar-powered aerial vehicle, it is small enough to sit on the palm and is engineered to fly indefinitely while the sun shines on its wings. Mingjing Qi professor at Beihang and the lead of the project says he doesn’t want to settle for this size of the drone. “My ultimate goal is to make a super tiny flying vehicle, about the size and weight of a mosquito, with a wingspan under 1 centimeter,” Qi notes.

Unlike the previous tiny aerial vehicles that rely on electromagnetic motors and generate power using electromagnets; CoulombFly uses an electrostatic field to produce motion. With a mass of 1.52 g, electrostatic motor can generate lift-to-power efficiency that’s twice or even thrice that of traditional MAV motors. The electrostatic motor of the tiny drone comprises two rings: the inner ring is a spinning motor with 64 carbon fiber slats covered with aluminum foil, while the outer ring has eight alternating pairs of negative and positive carbon fiber electrode plates also bonded with foil. When the CoulombFly is exposed to sunlight, the outer ring with its 16 plates generates electric fields. Since each electrode plate is embedded in aluminum brushes, these brush against the rotor slats on the inner ring spinning the propeller and lifting the drone up until the sun is shining on it.

Solar-Powered Fridge Doesn’t Require Electricity And Can Run For 40 Hours Without Power

Posted on by

In the privileged corners of the world, it’s easy to take for granted the amenities that define modern life—consistent electricity, reliable refrigeration, and an abundance of technological conveniences. However, a significant portion of the global population struggles to access what many consider basic necessities. This disparity underscores a broader issue: our comforts, powered by unsustainable practices, contribute to long-term environmental degradation. EasyFreeze finds a good balance between the two, embracing more sustainable alternatives, which is not just a nod to the past but a necessary step toward a viable future.

Designer: Amped Innovation

Imagine living in Lagos, Nigeria, where daily power outages can last for hours. In such conditions, a conventional refrigerator is nearly useless, and consequently, very few people own one. However, Amped Innovation, a forward-thinking startup, has developed a game-changing solution: the EasyFreeze, a solar-powered fridge designed to operate efficiently even with an unreliable grid or completely off-grid. This innovation is particularly transformative for regions rich in solar energy but poor in infrastructure.

The EasyFreeze is a meticulously designed fridge and freezer capable of refrigeration in under 20 minutes (reaching 8ºC) and freezing in less than an hour (0ºC). Unlike typical cold storage solutions, it maintains its temperature for up to 40 hours during power outages or on cloudy days, ensuring reliability in even the most challenging conditions.

A significant innovation within EasyFreeze is its use of an “ice battery” instead of traditional lithium-ion batteries. Lithium-ion batteries, while common, are expensive, prone to overheating, have a shorter lifespan, and pose safety risks. The ice battery system in EasyFreeze utilizes ice pouches embedded within the refrigerator walls to absorb and release heat. These pouches are cooled by solar panels during the day or by grid power when available, enabling the fridge to remain cold for extended periods without active power. This system not only enhances safety and durability but also significantly reduces costs.

Amped Innovation is rolling out the EasyFreeze across more than a dozen countries in sub-Saharan Africa and Asia, focusing on communities that are hardest to reach. Small businesses, such as corner stores, benefit immensely from the ability to sell cold beverages and ice, while medical clinics and hospitals can safely store medicines and vaccines at precise temperatures. The fridge’s design prioritizes off-grid efficiency, with proprietary circuits, software, and mechanical designs to deliver city-like performance in rural settings.

One of the distinguishing features of the EasyFreeze is its durability. Unlike many other solar refrigerators that fail within a year of use, the EasyFreeze is built to last. The equipment is assembled locally to avoid steep import fees and reduce costs, ensuring affordability without compromising on quality. This holistic approach to product design and distribution makes EasyFreeze not only efficient but also economically viable.

The EasyFreeze uses R-600a refrigerant, which has zero ozone depletion potential (ODP) and a very low global warming potential (GWP). It is at least 38% more energy-efficient than other market options, thanks to its powerful 225W compressor and thick, 75mm closed-cell polyurethane insulation. These features ensure the fastest cool-down times and the longest autonomy—maintaining efficient cold storage for up to 18 times longer than other freezers during power outages.

While the EasyFreeze is not inexpensive, retailers charge around $900, it remains within reach of middle-class families in countries like Nigeria. This price point reflects a commitment to quality and long-term affordability, prioritizing the total cost of ownership over the initial purchase price. Amped Innovation’s focus on high-quality materials and efficient design means EasyFreeze offers unmatched value, making it accessible to a broader audience.

The EasyFreeze’s utility extends beyond developing regions. Following the wildfires in Maui in 2023, the fridge garnered interest from residents in Hawaii. With electricity costs in Hawaii being exceptionally high, EasyFreeze offers a payback period of just two years, making it an economically attractive solution for both disaster resilience and everyday use.

As we acknowledge the privileges that many of us enjoy, it is crucial to recognize the pressing need for sustainable innovations that can bridge the gap for those less fortunate. The EasyFreeze exemplifies how thoughtful, eco-friendly design can transform lives, providing reliable refrigeration in areas with unreliable power. Amped Innovation’s focus on efficiency, durability, and affordability positions EasyFreeze to become a conventional choice for refrigeration in parts of Africa and Asia that receive ample sunlight. This remarkable appliance not only meets the immediate needs of its users but also paves the way for a more sustainable future.

Solar-powered sundial wall clock concept offers a unique way to tell the time

Posted on by

Today’s clocks and watches seem to be split between mechanical analog and electronic digital designs, but there are more than two ways to tell the time. Of course, some of these methods are regarded to be inaccurate, error-prone, and at the mercy of the elements, but there’s a certain charm and magical feeling to the way our ancient ancestors tried to discern the time of day. The sundial is one of the oldest time-keeping tools, one that works on the presumption that the sun travels the same path every day of the year, which isn’t exactly the case. Still, it’s not an entirely incorrect method and it can easily be fixed with modern technology, like this sustainable wall clock concept that is powered by the sun in more ways than one.

Designer: Begüm Kılınç

A sundial works by simply observing the shadow that a stick or a tall thin object casts on a flat surface, a shadow that moves around and grows or shrinks as the sun makes its way through the sky. The sun doesn’t travel the exact same path all year round, however, and this method definitely doesn’t work at night. Modern technology, however, has a way to shine a light 24/7, and this wall clock uses that to recreate the almost mystical appearance of a sundial while utilizing energy from the very sun that inspired it.

Name after the Egyptian god of the sun, the Ra wall clock utilizes an LED ring light to simulate the sun. But rather than shining from all directions, the light is focused on a single point to recreate the effect of a short stick casting a very long shadow. As time moves, so does the light move around the periphery of the circle, thus mimicking a sundial but with more consistency and accuracy. Plus, it works at night as it does during the day.

While this would have been enough to create a modern sundial clock, the concept takes the association even further by also following how the sundial of old needed only the sun to function. Rather than relying on batteries, Ra uses solar power to make sure the clock is running 24/7 without the need to charge it or change batteries. The transparent solar panel that makes up the wall clock’s front cover actually harnesses any light around it, so the clock doesn’t need to actually be exposed to the sun and can be used indoors or under low-light environments.

This design helps give the sundial wall clock a sustainable potential, even if it does minimally use some electronics as well as LED lighting. Unlike analog clocks, there are now complex mechanisms that are difficult to repair, and unlike digital clocks, there are no screens or displays to show the time. It uses a very simple method that traces its roots back to ancient times, but one that still has benefits to the people of today.

Solar-powered streetlights spin and move to chase the sun

Posted on by

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.

Solar-powered coffee truck concept runs on green fuel to bring black fuel anywhere

Posted on by

They say money makes the world go round, but coffee is probably just as critical for some people. Connoisseurs will undoubtedly tell anyone willing to listen to brew their own cup, but not everyone has the luxury of doing that daily. If you don’t know of a local shop you can call your home away from home, you’d probably be at the mercy of the big, expensive chains that put more sugar than you’re going to be comfortable with. Establishing a fixed store in a nook or building isn’t going to be cheap for some businesses, and it also means not being able to reach customers where they are. Coffee trucks can solve the problem of portability, but this concept design takes that idea even further by having the whole operation run on solar power, potentially bringing that coffee experience anywhere, even away from the grid.

Designer: Kyrolos Maged

Although you can see them almost everywhere, big chain stores like Starbucks won’t always please everyone. Some simply don’t like their selection or the way they do business. Others simply prefer to patronize smaller businesses to help them grow and thrive. Either way, the majority of these stores force you to go to their location, which is not a problem unless there isn’t one nearby. It would definitely be great if the coffee could come to where the people are rather than the other way around, which is what coffee trucks are trying to do.

Although they are a viable business model, such mobile coffee dispensing stores have a few logistic issues to iron out, specifically one of power. Sure, you can run the machines on the same battery that drives the truck, but it also risks you running out of fuel when you need it the most. And with some vehicles turning to electric power, such a power source might no longer be feasible. This unnamed concept thus turns toward an ever-present source, at least during the time when people are most likely to chug their black or brown fuel.

The solar-powered coffee truck is exactly as it sounds, an operation that runs on solar energy rather than fuel or car batteries. There’s a single large solar panel on top of the truck, but it’s easy enough to extend the design to have multiple panels on the “wings” that fold out from the sides of the truck. This way, the energy needs of the coffee machines and the truck itself are kept separate and you don’t have to worry about one eating into the reserves of the other.

The design of the truck itself is pretty standard, with sliding tables to let customers put down their cups for a while or enjoy some sandwiches that the mobile cafe might offer. What’s interesting, however, is the idea that the coffee truck would offer all sorts of coffee, including those from capsule machines. It’s a good way to diversify and hit many types of customers while also ensuring the speed of service, though pure-blood coffee lovers might turn their noses up at such a thought.

Solar lights can be your aesthetic illumination under the night sky

Posted on by

When you spend a lot of time in your backyard or outdoors, having lights that contribute to the ambience and illuminate the place is a must. If you’re eco-friendly of course, you would prefer solar lights although not all that are available in the market have that of a good design. Lately we’ve been seeing lights with better aesthetics, have multiple purposes, and use sustainable energy instead of your usual electricity.

Designer: Mpowerd

The Luci Solar Site Lights is one such product that meets all of that criteria. You can use them as “stringless string lights” or you can also stake them on the ground or put them up wherever you would need aesthetic lighting. They are able to illuminate up to 1,000 square feet and can last up to 20 hours on a single charge. The light nodes are IPX4 which means that they can survive splashes of water but cannot be submerged in it.

There are three light modes that you can choose from: low, medium, and high and they have dual-directional on/off swivel. They can light up gardens, picnic areas, and other outdoor settings. You can also use it indoors if you want by putting a glass or transparent cup to diffuse it. Each set comes with 6 hangable and weatherproof lights, 6 ABS stakes with notch, and a rechargeable 2,600 mAh battery with recharge case that has a built-in solar panel but can also be charged through USB-C charging.

These lights are portable enough that you can bring it whenever and wherever you want to have a party under the night sky. You can even put them on your pets or on yourself if you need to walk around with lights instead of carrying a flashlight. And since they are solar powered (but with the option to still charge if you didn’t get enough sunlight), you get to lessen your carbon footprint.

Award-Winning Solar-Powered Aircraft Ushers in a New Era of Zero-Emission Travel

Posted on by

Carbon-neutral flight seems to quite literally be on the horizon with this conceptual falcon-shaped aircraft. The eponymously named Falcon Horizon embraces the boundless potential of solar power with a uniquely designed body that additionally helps with lift and allows the aircraft to navigate the skies. Departing from conventional aircraft design, this concept harnesses the advantages of flying wings, drawing inspiration from the efficiency of birds of prey.

Designer: Laszlo Nemeth

In an era where solar-powered manned flight is not only possible but actively under development, the aviation industry carries a weighty responsibility to chart a sustainable course. Falcon Solar minimizes the need for cumbersome batteries, leveraging solar energy not just for propulsion, but also for shaping the boundary layer around the wing, unlocking heightened efficiency. The solar panels extend from one wing to another, covering a massive area of the airplane, and therefore providing it with the power it needs to complete its journey. The delicate balance between propulsion and boundary layer manipulation yields superior overall performance.

As we witness the dawn of a new age in aviation, Falcon Solar stands as a testament to the potential of clean, renewable energy sources to reshape the skies. Although just a concept for now, its innovative format speaks to the collective aspirations of a world seeking greener horizons, while propelling us towards a future where the sky truly knows no limits.

Rotating bench “spins ever so slowly” using solar energy

Posted on by

In one of the fiction books that I read lately, one of the projects that this girl was trying to do was to propose an eco-friendly amusement park with some of the rides using solar energy and most of the materials to be used are from recycled or sustainable materials. It was a pretty good idea although I thought maybe in the real world this was something not that viable. Well we still don’t have one but there is a new art installation that might fit in with that fictional amusement park.

Designer: ENESS

This permanent outdoor installation is called A Solar-Powered Bench That Spins Ever So Slowly and the name is also the actual description of this idea. It is a circular bench shaped like a flower if viewed from above and depending on how strong the sun is, it will spin around either ever so slowly or a bit faster if the sun is out in full force. It is a clever idea for something that is functional, decorative, and of course, sustainable.

The bench is actually made from custom solar panels and rotomolded with low-density polyethelene (LDPE) and recycled plastic. It stores sunlight into the panels and when it is sunny, it will spin faster (although not fast enough to make anyone dizzy) and on cloudy days, then it will live up to its name as it spins ever so slowly. The design itself follows mid-century modern furniture and if you view it from above, it looks like you have a garden of flowers in pastel colors spinning in the midst of an actual garden.

The concept is meant for people to interact with the benches and to have a different perspective of public space. People are meant to relax while it spins or have conversations with other people sitting on the bench or the one across. It would be nice if it could be replicated in other places where solar power is a viable energy source and places where there are a lot of relaxing, public spaces.
