Inventor Turns Cardboard Boxes Into Eco-Friendly Oven

How cool is this?

(CNN) -- When Jon Bohmer sat down with his two little girls for a simple project they could work on together, he didn't realize they'd hit upon a solution to one of the world's biggest problems for just $5: A solar-powered oven.

Inventor Jon Bohmer with the oven he has made out of a cardboard box.






The ingeniously simple design uses two cardboard boxes, one inside the other, and an acrylic cover that lets in the sun's rays and traps them.
Black paint on the inner box, and silver foil on the outer one, help concentrate the heat. The trapped rays make the inside hot enough to cook casseroles, bake bread and boil water.
What the box also does is eliminate the need in developing countries for rural residents to cut down trees for firewood. About 3 billion people around the world do so, adding to deforestation and, in turn, global warming.
By allowing users to boil water, the simple device could also potentially save the millions of children who die from drinking unclean water.
Bohmer's invention on Thursday won the FT Climate Change Challenge, which sought to find and publicize the most innovative and practical solution to climate change.
"A lot of scientists are working on ways to send people to Mars. I was looking for something a little more grassroots, a little simpler," Bohmer said Thursday.
Bohmer, a Norwegian-born entrepreneur based in Kenya, said he also had been looking at solutions "way too complex, for way too long."

"This took me about a weekend, and it worked on the first try," Bohmer said. "It's mind-boggling how simple it is."


The contest was organized by the Forum for the Future -- a sustainable development charity -- and the Financial Times newspaper. Among the judges were British business magnate Richard Branson and environmentalist Rajendra Pachauri. The public also voted on the finalists.
Bohmer's invention beat about 300 other entries, including a machine that turns wood and other organic material into charcoal, wheel covers that make trucks more fuel efficient by reducing drag, and a feed supplement for livestock that reduces the methane they emit by 15 percent.
Bohmer named his invention the Kyoto Box, after the international environmental treaty to reduce global warming.
The box can be produced in existing cardboard factories. It has gone into production in a factory in Nairobi, Kenya, that can churn out about 2.5 million boxes a month.
Bohmer has also designed a more durable version, made from recycled plastic, which can be produced just as cheaply.
He envisions such cardboard ovens being distributed throughout rural Africa.
"In the West, we cook with electricity, so it's easy to ignore this problem," he said. "But half the world's population is still living in a stone age. The only way for them to cook is to make a fire.

"I don't want to see another 80-year-old woman carrying 20 kilos of firewood on her back. Maybe we don't have to."

That's great! So simple, and so revolutionary.
It's like an EZ Bake Oven for grownups! Cool!

I loved my EZ Bake oven.
No MAS.

Cool! I want one. Seems good for camping. And cooking will take less time and energy for rural populations.

I did a similar project in 5th grade. We had to make nachos in a cardboard oven. My cheese didn't melt.

One problem:

I cannot stand when we, Westerners, place the blame of global warming/overpopulation/whatever on developing countries. Riiiight. It's totally their fault. Like we don't greatly contribute to the deforestation of this planet.

Cool!

Phoenix, it's Easy Bake for the Modern Age!

Solar ovens have been around for a while. Some other Peace Corps volunteers had them in Uganda. They hadn't really caught on with Ugandans, but it would be cool if they would. The ones I've used only worked so-so. You could bake muffins or banana bread in them, but it took all day. Maybe they needed more insulation or something.
Yeah, blame was too strong of a word in this case. And little things do add up. I am all for saving the trees. I was just reacting to the tone of the whole "green" movement. Misplaced venting.

When I was in 7th grade, my science class studied solar ovens and we formed groups that designed a similar oven out of plexiglass, foil, and cardboard. They all worked, some faster than others. It's definitely nothing new because this was nearly 20 years ago but good for him for getting some notoriety.
