World's First Solar-Powered Smartwatch Harvests Both Natural and Artificial Light

A big problem with smartwatches is that, compared to traditional watches, the internal battery can easily run out of juice.
But a San Francisco-based startup has taken a major step in solving this problem by creating the LunaR, which claims to be the world's first solar-powered smartwatch.
<p style="">
"We love watches, we LOVE technology AND we hated the fact that we're always stressed out about recharging our devices," the company touts on their <a href="https://www.kickstarter.com/projects/lunarsmartwatch/lunar-the-worlds-first-solar-powered-smartwatch/description" target="_blank">Kickstarter</a> crowdfunding page. "We felt those elements hadn't been tackled and we wanted to expressed a harmonious connection between the beauty and simplicity of an elegant timepiece with the 'smarts' of a smartwatch."
</p><p style="">
Casio and Citizen already make solar-powered wristwatches, but the LunaR appears to be the first smartwatch that can run off of the sun's rays.
</p><p>
A transparent solar panel made by France-based Sunpartner covers the watch face. Inside the watch is a 110-mAh lithium-polymer battery that can supposedly run with as little as one hour of artificial or natural light.
</p><p style="">
"With a full charge, the battery will last up to at least 3 months, depending on the amount of notifications you're receiving. If you're able to collect passive sun while outside each day for like 1 hour (with a exposure greater than 10K LUX), then you (almost) never have to charge your watch again," the company said.
</p><p>
The watch works with a companion smartphone app to offer features such as sleep and activity tracking, integration with social media and messaging apps, and can auto-update the time wherever you are using the phone's GPS. Notifications are displayed on the embedded LED or through vibration technology. It's also waterproof up to 164 feet and comes with a traditional USB charger for backup.
</p><p style="">
LunaR's successful crowdfunding campaign has already racked up more than 500 backers to date. Models start at an early-bird price of $138 <a href="https://www.kickstarter.com/projects/lunarsmartwatch/lunar-the-worlds-first-solar-powered-smartwatch/description" target="_blank">on the site</a>.

Bringing your own reusable grocery bags when you go shopping is one of the easiest ways to cut down on your plastic consumption — according to the UN Environment Program, up to 5 trillion single-use plastic bags are used globally each year.
The most sustainable option is to use a bag you already have, whether it's an old tote or a laundry basket (thank TikTok for that idea). You can also make your own reusable grocery bags out of T-shirts. But if you'd rather purchase designated reusable grocery bags, here are our recommendations.

<h2>Why switch to reusable bags?</h2><p>The <a href="https://www.unep.org/interactive/beat-plastic-pollution/" rel="noopener noreferrer" target="_blank">UN says</a> people produce 300 million tons of plastic waste each year, and about 60% of the plastic produced since the early 1950s has ended up in a landfill or the natural environment.</p><p>Plastic grocery bags are made from low-density polyethylene (LDPE). Technically, this type of <a href="https://www.ecowatch.com/plastic-recycling-myth-2647706452.html" target="_self">plastic can be recycled</a>. However, in practice, plastic bags easily clog recycling machinery, so <a href="https://millerrecycling.com/ldpe-out-of-landfills" rel="noopener noreferrer" target="_blank">most municipal recycling centers</a> do not accept this type of material. </p><p>A <a href="https://www.epa.gov/sites/production/files/2018-07/documents/smm_2015_tables_and_figures_07252018_fnl_508_0.pdf" rel="noopener noreferrer" target="_blank">study by the EPA</a> showed that only about 6% of the LDPE generated in 2015 was recycled. Other types of plastic, by comparison, were recycled at 18% and 10% rates.</p><div class="redactor-editor" dir="ltr" placeholder="Start writing..." spellcheck="false"></div><p>Although some grocery stores offer plastic bag recycling, the easiest way to get around this is to refuse plastic bags in the first place. Many cities have instituted <a href="https://www.ecowatch.com/new-york-plastic-bag-ban-begins-2645319695.html" target="_self">plastic bag bans</a>, but more often than not, it's up to individuals to choose to make the switch to reusable grocery bags in their day-to-day lives.</p><p><em><em><a href="https://www.ecowatch.com/about-ecowatch-2641507575.html?rebelltitem=47#rebelltitem47" target="_self">Melissa Smith</a> is an avid writer, scuba diver, backpacker, and all-around outdoor enthusiast.
