3 Solar Ovens That Give You the Power to Cook With the Sun
With barbecue season around the corner, what could be more planet-friendly than cooking with the sun? Instead of gas/electricity/charcoal/wood, a solar cooker harnesses heat from the sun to cook food.
From baking cookies to frying eggs, these pollution-free devices work wherever there is sunshine, regardless of how cold it is outside. With ample sunlight, most get into temperatures between 250-350 degrees Fahrenheit, with some top end varieties going nearly 600 degrees.
Solar cookers come in all shapes, sizes and price ranges and you can even DIY. Here are instructions for solar box cookers, parabolic cookers and panel cookers. And here's a kid-friendly version from NASA that basically requires a cardboard box, plastic wrap, aluminum foil and regular office supplies.

Solar cookers are ideal for people who enjoy camping outdoors or live off-grid, but for people in energy-impoverished nations, they can be a lifesaver when fuel is limited or if water needs purification. Developed for use in refugee camps in 1995, the $39.00 CooKit panel cooker is made of cardboard and aluminum foil and is the most widely-used solar cooker in the world. The CooKit is incredibly portable as it folds flat into a 13-by-13 inch square that's 2 inches thick. Cooking temperature range is 180-240 degrees Fahrenheit.
As Insights writer Eric Hoffner pointed out, "lack of access to such clean cooking options is a huge issue globally: 3 billion people cook their daily meals over smoky biomass fires every day causing more than 4 million annual mortalities, mostly women and children, from smoke inhalation related diseases. Not only is it a human health issue, but forests and the climate suffer: most households that rely on smoky stoves burn 2 tons of biomass per year, about 730 million tons globally, which releases about a billion tons of carbon dioxide. The resulting particulate matter also traps heat in the atmosphere."
Food gets “steam-fried” inside this unique, tubed-shaped solar cooker making it ideal for vegetables and meats and even baking bread. A GoSun was one of the solar-powered stoves featured on a December episode of Bravo’s hit reality cooking competition Top Chef. Host Padma Lakshmi gave the contestants 30 minutes to create a dish with “the cleanest energy there is—the sun.”
GoSun social designer Matt Gillespie told EcoWatch last year that the GoSun Grill can roast a meal for eight as fast as a grill. And since it has a thermal battery, users can cook whenever they want to, even if it’s cloudy. The company sells different iterations of stoves online, such as the 7 lbs. GoSun Sport and the industrial sized GoSun Station. The products can reach temperatures of 550 degrees Fahrenheit and can cook a meal in 20 minutes, depending on what’s being cooked and the amount of sunlight.
In the video below, a YouTuber shows how she cooked a batch of moist brownies with the oven.
Think of the Solavore Sport as a crockpot within an oven. Here's how it works: Sunlight enters through the transparent cover and hits internal cooking pots that transform light into heat. Heat builds inside the longer it sits while the exterior of the box remains cool to the touch.
TreeHugger's Derek Markham recently reviewed the unit and said that the 9-pound cooker is "light and portable, and a convenient addition to home cooking."
The Sport can roast, bake, steam using only solar energy. "Using the natural moisture in meats, fish, and vegetables, the Sport cooks without additional water so all the natural vitamins and minerals are retained, giving food a wonderful rich flavor," the company says.
"Using something as simple and elegant as a black box with a lens on top, putting your pots inside and knowing that all day the sun's going to be making that dinner," Solavore CEO Anne Patterson says in the video. "There's something just beautiful about that simplicity."
The company is even paying it forward with each purchase. Every solar oven that's purchased helps fund a Solavore Sport somewhere in the world where an open fire is still the main kitchen appliance.

One million species are at risk of extinction from human activity, warns a recent study by scientists with the United Nations. We need to cut greenhouse gas pollution across all sectors to avoid catastrophic climate change — and we need to do it fast, said the Intergovernmental Panel on Climate Change.
This research should serve as a rallying cry for polluting industries to make major changes now. Yet the agriculture industry continues to lag behind.
"The Ministry of Environment, Natural Resources Conservation and Tourism wishes to inform the public that following extensive consultations with all stakeholders, the Government of Botswana has taken a decision to lift the hunting suspension," the government announced in a press release shared on social media.
Company Safety Data Sheets on New Chemicals Frequently Lack the Worker Protections EPA Claims They Include
By Richard Denison
Readers of this blog know how concerned EDF is over the Trump EPA's approval of many dozens of new chemicals based on its mere "expectation" that workers across supply chains will always employ personal protective equipment (PPE) just because it is recommended in the manufacturer's non-binding safety data sheet (SDS).

From 2009 to 2012, Gregory Jaczko was chairman of the Nuclear Regulatory Commission, which approves nuclear power plant designs and sets safety standards for plants. But he now says that nuclear power is too dangerous and expensive — and not part of the answer to the climate crisis.

When Greg Wetherbee sat in front of the microscope recently, he was looking for fragments of metals or coal, particles that might indicate the source of airborne nitrogen pollution in Rocky Mountain National Park. What caught his eye, though, were the plastics.
In a big victory for animals, Prada has announced that it's ending its use of fur! It joins Coach, Jean Paul Gaultier, Giorgio Armani, Versace, Ralph Lauren, Vivienne Westwood, Michael Kors, Donna Karan and many others PETA has pushed toward a ban.
This is a victory more than a decade in the making. PETA and our international affiliates have crashed Prada's catwalks with anti-fur signs, held eye-catching demonstrations all around the world, and sent the company loads of information about the fur industry. In 2018, actor and animal rights advocate Pamela Anderson sent a letter on PETA's behalf urging Miuccia Prada to commit to leaving fur out of all future collections, and the iconic designer has finally listened.
If people in three European countries want to fight the climate crisis, they need to chill out more.
"The rapid pace of labour-saving technology brings into focus the possibility of a shorter working week for all, if deployed properly," Autonomy Director Will Stronge said, The Guardian reported. "However, while automation shows that less work is technically possible, the urgent pressures on the environment and on our available carbon budget show that reducing the working week is in fact necessary."
The report found that if the economies of Germany, Sweden and the UK maintain their current levels of carbon intensity and productivity, they would need to switch to a six, 12 and nine hour work week respectively if they wanted keep the rise in global temperatures to the below two degrees Celsius promised by the Paris agreement, The Independent reported.
The study based its conclusions on data from the UN and the OECD (Organisation for Economic Co-operation and Development) on greenhouse gas emissions per industry in all three countries.
The report comes as the group Momentum called on the UK's Labour Party to endorse a four-day work week.
"We welcome this attempt by Autonomy to grapple with the very real changes society will need to make in order to live within the limits of the planet," Emma Williams of the Four Day Week campaign said in a statement reported by The Independent. "In addition to improved well-being, enhanced gender equality and increased productivity, addressing climate change is another compelling reason we should all be working less."
Supporters of the idea linked it to calls in the U.S. and Europe for a Green New Deal that would decarbonize the economy while promoting equality and well-being.
"This new paper from Autonomy is a thought experiment that should give policymakers, activists and campaigners more ballast to make the case that a Green New Deal is absolutely necessary," Common Wealth think tank Director Mat Lawrence told The Independent. "The link between working time and GHG (greenhouse gas) emissions has been proved by a number of studies. Using OECD data and relating it to our carbon budget, Autonomy have taken the step to show what that link means in terms of our working weeks."
Stronge also linked his report to calls for a Green New Deal.
"Becoming a green, sustainable society will require a number of strategies – a shorter working week being just one of them," he said, according to The Guardian. "This paper and the other nascent research in the field should give us plenty of food for thought when we consider how urgent a Green New Deal is and what it should look like."
