Pedal with the energy of the sun on Kvaern’s solar-powered ebike

KVAERN E-BIKE / KVÆRN E-BIKE

Electric bikes have revolutionized the bicycle industry, bringing one of the oldest modes of transportation into the 21st Century. However, like most of the electronic tech we interact with each day, the mere act of recharging a bike isn’t exactly a convenient chore. But thanks to a new solar-powered ebike from the Copenhagen-based startup Kvaern, requiring a power outlet to recharge your ride may be a thing of the past.

Powered by a stationary battery pack the company refers to as Kvaern+, the device amasses power by storing the solar energy it generates throughout the day. Whenever the bike needs a bit of a jolt, the power packs allow the accumulated solar energy to transfer to the bike, allowing riders to go roughly 31 miles on a single charge. No plug-ins or wires necessary — Kvaern’s ebike is fully off-grid. The company’s founder, Jonas Gissel, even points to Tesla’s Powerwall as a source of inspiration.

“No doubt, Tesla has been a great inspiration for Kvaern, and like pretty much the rest of the world, we are very impressed with what they have managed to do to the car industry,” Gissel said. “With the electric bike, we’re facing a revolution in the bike industry as we know it. Whether fully electric or hybrid, this is the future.”

Similar to how Tesla charging stations have begun popping up across the country, Gissel intends to pursue public installations of Kvaern’s system down the line. For now, the company’s focused on perfecting its personal power packs before scaling the tech. The idea is to deliver “smart, affordable, and cool everyday-products that run on green energy.”

In addition to the bike’s 31-mile range, it’s also capable of accelerating from zero to roughly 15 mph in just four and a half seconds and sports a 250-watt motor. It’s unclear if the 15 mph is the bike’s top speed but if it is, it’s worth pointing out that it would be roughly 10 or so mph slower than most pedal-assisted ebikes on the market.

Kvaern’s bike isn’t yet available but the brand is currently taking pre-orders through its website or Facebook page.

Solar Orbiter to perform its riskiest flyby before heading to the sun

The European Space Agency's Solar Orbiter is on a mission to study the sun, but to get there it has to perform a series of flybys of other planets including Earth. This week, the Orbiter will perform its riskiest flyby, dipping through the smattering of space debris that surrounds Earth before whipping away toward the sun.

Solar Orbiter will reach its closest point to Earth on Saturday, November 27 at 6:30 a.m. ET (3:30 a.m. PT), when it will be within 286 miles of the planet's surface over North Africa and the Canary Islands. That's only a little above the orbit of the International Space Station, demonstrating just how close the spacecraft will come to us, and it will have to pass through two rings of space debris in both geostationary orbit and low-Earth orbit.

Sun throws a Halloween tantrum, with a solar flare impacting Earth this weekend
An X1.0 class solar flare flashes in center of the Sun on Oct. 28, 2021. This image was captured by NASA's Solar Dynamics Observatory and shows a blend of light from the 171 and 304 angstrom wavelengths.

The sun has been unusually active this week, culminating in a large solar flare which it threw off at 600 miles per second in the direction of Earth on Thursday, October 28. The flare is an X1-class flare, with X-class being the most intense form of flares. The burst of radiation is heading toward us and will strike the Earth this weekend, but don't worry -- it won't harm you on the ground, though it could cause issues for satellite communications.

GoSun’s new portable power stations use the sun’s ray to charge devices
gosun new portable power stations gets you through outages power550 hero

GoSun's diverse lineup of solar-friendly products is expanding this week with two new portable power stations. The GoSun Power 550 and Power 1,100 are high-capacity batteries designed to help keep your appliances running when off the grid, whether that's due to an outage or being on a camping trip. Much like its other eco-friendly devices, these portable power stations can be charged using solar panels.

These portable power stations have plenty of power output options, including a 600-watt AC, a 1,000W AC, USB-A with QuickCharge 3.0, two 5V 2.4A USB-A plugs, a 60W USB-C plug, and a 12.3V DC. For charging, they use a 12-24V adapter, 18-24V input for solar, or 12V if you're charging it from the car.  Both AC outlets are pure sine wave, meaning your electronics get a more consistent feed of power. That's good news for your phones and laptops. It also has a Maximum Power Point Controller (MPPT) built-in, which helps to optimize the gain from solar panels. Other batteries lose a lot of efficiency on this front.
