Lightfoot: A Solar-Powered Scooter

Today Otherlab, a sort of incubator/skunkworks, unveiled this aluminum-framed Lightfoot scooter.

It's got a 48-volt, 1.1kWh battery that provides up to 37 miles (60 km) of range, and which can be charged at a standard wall socket. But as you've undoubtedly noticed, the scooter has rather a lot of solar panels. Otherlab says you can use the sun to get up to 18 miles (28 km) of additional range. "Each hour of sunbathing recharges Lightfoot with 3 miles of solar-powered freedom," the firm writes.

I can't imagine why they've not photographed this, but the Lightfoot reportedly sports a lockable storage compartment that can hold "more than 1.5 cubic feet (45.2 liters)–comparable in size to a carry-on suitcase," Otherlab writes. "This compartment can comfortably fit up to 33 lbs. (15kg) of cargo, enough space for three large grocery bags, a work bag, a helmet or anything else you need to stash on your travels. Its weatherproof design and sturdy lock protect your stuff from prying eyes and the elements, ensuring your belongings arrive as safely as you do."

The Lightfoot is retailing for $4,995, and is expected to ship in January.

OSCE Project Co-ordinator lights up central Tashkent with 20 solar-powered street lamps

TASHKENT, 29 July 2016 - A central area of Tashkent is to be lit by 20 autonomous street light systems fully powered by solar energy as part of a pilot project officially launched today by the OSCE Project Co-ordinator in Uzbekistan.

The Co-ordinator is supporting the host country in the area of green economy policies, including the analysis of costs and benefits in using environmentally-friendly and sustainable systems in street lighting and urban planning.

Senior Project Officer at the OSCE Project Co-ordinator Hans-Ullrich Ihm said that urban street lighting powered by solar energy is one of many possibilities that contribute to preserving our environment by reducing the consumption of fossil fuel and emissions. He added that the Project Co-ordinator strives to support the government in implementing policies advocating for such technologies.

The ‘Lightfoot’ Electric Scooter Lets You Literally Ride a Solar Panel Around Town

I’m kinda in awe of this goofy solar scooter

This is Lightfoot, a solar scooter conceived by San Francisco-based R&D outfit Otherlab that, it claims, will be available to buy in the US from January. The most eye-catching feature are the two side panels covered in solar cells that will hopefully keep you from needing a charger. In the gap between the two, however, is a fairly capacious cargo compartment with almost 1.6 cubic feet of space. That should be more than enough to haul your gear to and from work, or to pick up some groceries when you’re out and about. The padded seat and footplates, too, are designed to carry the rider and an additional passenger when required, too. 

Specs-wise, there’s a pair of 750W brushless DC motors with a top speed of 20 miles per hour, generating 90Nm of peak torque, which should hopefully be enough to scale the hills around SF (and wherever you are). They’re wired up to a 1.1kWh battery that the company promises will deliver a range of 37 miles on a single charge. The two 120W panels on either side will trickle charge the battery when on the road or parked up outdoors. Otherlab claims this idle solar charging will add three miles of charge per hour, or 18 miles if you leave it for a whole day.

Lightfoot / Otherlab

Aside from the solar hardware, Otherlab claims that you — or a qualified technician — will be able to keep this running without any outside assistance. It said most of the components are off-the-shelf motorcycle parts and that they can be repaired or replaced just as easily. There’s also a one-year whole-bike and two-year mechanical guarantee, as well as a no-question buy back policy. We’ll reserve judgment on every facet of this until we’re able to test it for ourselves, but we’re looking forward to doing so just to see what this thing feels like to ride.

Pre-orders for the Lightfoot are opening today for $4,995, with Otherlab pledging to make the first deliveries in January 2025.
