it's weird, but legal for some reason. Giving back energy to the grid can cost money. Shy of just stacking a bunch of batteries, what could I do with the spare summer sunlight?

An Indian entrepreneur is using sugar, cellulose, and corn fibers to make a plastic-like carrier bag for small Indian businesses.

His company Bio Reform has already replaced 6 million plastic bags in the checkout counters of stores all over India.

Based in Hyderabad, Mohammed Azhar Mohiuddin first got the idea during the general mayhem that arose during the pandemic. Mohiuddin was looking at global environmental issues with the hope of finding one his entrepreneurial spirit had the capacity to tackle.

Hi. Hopefully someone can help me out. I have installed Combustible as an Android Lemmy client but when I try to connect to https://slrpnk.net I get an error: "unable to connect to specified Lemmy instance!" I'm willing to try a different app but would prefer FOSS.

Herbicides have a long history of negative consequences. Glyphosate and paraquat, among other pollutants, are extremely harmful to human health and the environment. These pollutants impair soil quality and destroy beneficial organisms such as pollinators. Furthermore, the widespread use of herbicides has resulted in weed resistance, making chemical management less effective.

Kenny Lee, co-founder and CEO of Aigen Robotics, is personally committed to reducing pesticide use. Lee, a glyphosate-related non-Hodgkin lymphoma survivor, has collected $19 million for his startup to produce solar-powered weeding robots. “We’re on a personal mission,” Lee says, emphasizing their dedication to sustainable agriculture.

"To help feed the country’s population, an inventor, Toufic Hamdan, created a commercial bakery to bake bread in solar ovens. The startup “Partners With Sun” has installed a solar convection oven on the bakery’s roof. The Solar Oven uses large silver mirrors to capture and magnify the sun’s rays to build heat. The heat is transported by a transfer fluid which is then used to help operate a convection oven, allowing it to reach a baking temperature of between 300 and 400 Celsius. The heat is used directly in food and beverage production. " Baking Bread in a Solar Oven | Happy Eco News

According to the company website, “The Solar Oven cuts up to 80% of the bakery’s fuel bill.”

Derek Sherrell shows a low cost, open source house that he built in 90 days. He is giving away the plans for free for anyone who wants to build their own.

Open source is a wonderful concept that should be applied to everything, not just software.
