The Soccket soccer ball by Uncharted Play turns the kinetic energy created in a casual soccer game into electric light. Inside, there's a pendulum-like technology that converts the ball's movement into stored electricity for an on-board LED light. Young people in the developing world where electricity availability may be spotty can play in the day and read at night. The Soccket sounds like brilliant responsible design to us. Made in America, the Soccket is launching production via Kickstarter now.
At this point, there really shouldn't be much of negative stigma about pre-fabricated construction. The days of poorly built and aesthetically dull box homes are long gone, and new companies like Spain's Infiniski (an offshoot of the firm james&mau) offer modern, green, modular buildings at prices much lower than traditional construction. The strength of Infiniski's prefab lines is that they're almost infinitely customizable. They've used the same basic forms to build a one bedroom surf house on a beach, a multi-story condo building in Chile, dozens of rural homes, and even commercial buildings like a deli and retail shop. The environmental advantage of Infiniski is twofold: a percentage of the building materials is sourced from recycled suppliers, and each home can be customized with ventilation systems that minimize energy use.
