Zero Electricity Air Cooler

Over 70% of Bangladesh’s population live in corrugated tin huts across the countryside. During the long summer months, temperatures reach up to 45° Celsius, making these huts unbearable to live in.
To address the issue, Grey Dhaka teamed up with volunteers from Grameen Intel Social Business Ltd to create the Eco-Cooler – a zero electricity air cooler, which uses re-purposed plastic bottles cut in half and put into a grid, in accordance to available window sizes.
Based on wind direction and airflow pressure, the Eco-Cooler has succeeded in decreasing the temperature in tin huts by up to 5° Celsius. After initial tests, blueprints of the Eco-Cooler were put up online for everyone to download for free.

Smart Technology is a Solution Looking for a Problem

Technologies like driverless cars and smart heating systems could end up making cities dysfunctional according to Maarten Hajer, chief curator of the International Architecture Biennale Rotterdam 2016. Speaking at an opening event for the biennale, Hajer called for architects and designers to stop treating the advent of smart technologies as inevitable, and to question whether they will solve any problems at all.
“People with lots of media force pretend to know exactly what the future will look like, as if there is no choice,” he said. “I’m of course thinking about self-driving vehicles inevitably coming our way.” Discussions about the future of cities are at risk of being “mesmerised” by technology, he added. “We think about big data coming towards us, 3D printing demoting us, or the implication of robots in the sphere of health, as if they are inevitabilities. My call is for us to think about what we want from those technological advances.”
“I have nothing against good technology, it’s wonderful, but you always want social problems to be the priority. If it doesn’t help us get CO2 down, if it doesn’t help us make cities more socially inclusive, if it doesn’t help us make meaningful work, I’m not interested in smart technology. Sometimes I think: “if smart technology is the solution, then what was the problem again?”

Roads and Electricity? No, Thanks

To hear Ati Quigua tell it, New York City is a place where people who don’t know each other live stacked inside big buildings, gorging on the “foods of violence,” and where no one can any longer feel the Earth’s beating heart.
Quigua, an indigenous leader whose village in Colombia sits on an isolated mountain range rising 18,700 feet (5,700 meters) before plunging into the sea, is just one of over 1,000 delegates in town for the 15th Session of the United Nations Permanent Forum on Indigenous Issues that ends Friday.
“On top of the temples of the goddess and Mother Earth, they are building castles, they are building cities and building churches, but our mother has the capacity to regenerate,” Quigua said. “We are fighting not to have roads or electricity — this vision of self-destruction that’s called development is what we’re trying to avoid.”

Electrically Powered Bicycle Trailer & Hand Cart (DIY)

The German-made Carla Cargo is a three-wheeled cycle trailer with an electric assist motor. It can be pulled by any type of bicycle (including a cargo cycle or an electric bike), and it allows you to carry heavy (up to 150 kg) and bulky cargo (a loading platform of 60 x 160 cm). Uncoupled from the bicycle, the Carla Cargo works as a hand cart for large or heavy loads. The vehicle weighs 40 kg including the battery, and has a range of 40 to 60 km.
The electric motor is built into the front wheel and can produce 250 watts as a trailer (up to 23 km/h), and 500 watts as a handtruck (up to 6 km/h). The lithium-ion battery has a capacity of 11 or 15 Ah. The vehicle has two disk brakes and a parking brake, which are controlled via the handle or the bicycle handlebar.
The Carlo Cargo sells for about 4,000 euro. The construction manual is freely accessible online, but only in German for now. The trailer/handcart is present at the International Cargo Bike Festival, April 16-17, in Nijmegem, the Netherlands.
