Using the free energy supplied by the sun to cook our food is a great way to get started with renewable energies and sustainable and appropriate technology, but because most of the solar ovens on the market are large and unwieldy, and not very efficient, solar cooking hasn’t been very widely adopted, except in places with no other alternative.
But a new portable high-efficiency solar stove that can heat up quickly and efficiently, as well as hold the heat in during cloudy intervals, promises to bring solar cooking into the 21st century.
The GoSunStove, weighing in at just 3.5 pounds, has adjustable parabolic reflectors to focus the sun’s rays on the cooking tube, which is an evacuated tube (similar to a Thermos) capable of generating and holding temperatures of up to 550°F. The device, which is 24 inches long and can be set up in seconds, and is said to be able to cook simple meals or heat water in as little as ten minutes, with a capacity of three pounds of food or 50 oz in liquids.
“Designed for simplicity, durability, and mobility. GoSun offers a convenient, user friendly package for our fast paced lives. The GoSun is as simple in principal as it is powerful, effectively retaining 90% of all sunlight that enters its reflectors. The technology relies on the principles of parabolic reflection, evacuation (for it insulating value) and the Greenhouse effect, to make the most advanced solar cooking device to date.” – GoSunStove
And this solar stove isn’t just for campers or urbanites going green, but is also an integral part of the company’s empowerment program, which aims to put one out of every six GoSunStoves sold into the hands of a family in need, in order to help break the cycle of poverty.
“Today nearly 3 Billion people cooked with dirty fuel sources, such as wood, dung or charcoal. As a result, the second leading cause of death on Earth is smoke inhalation related illness. The simple act of cooking food is a complicated matter for nearly half of the world population. Three billion people on our planet rely on wood for cooking fuel, which results in harmful consequences to women, children and the environment.”
The GoSunStove is in a crowdfunding phase right now, with a campaign on Kickstarter to get the funding to begin a production run (instead of being built in small quantities, as they are now). If you pitch in to this campaign at the $79 level, you can get a Mini GoSunStove as a reward, and at the $219 level, you can be one of the first to get your very own full-size GoSunStove.
