In other tech news, the world's first 3D-printed laptop topped its crowdfunding campaign goal, raising more than $120,000. The design is completely open-source, and it's community-supported. Soda and water are polar opposites -- one is the foundation of life as we know it; the other is responsible for widespread obesity and diabetes.

Do you ever find yourself chanting, "There's no place like home," when you're looking for a cab late at night? A new device lets you make like Dorothy and hail a ride home with a click of your heels.
Flying cars have long been a staple of science fiction movies and books, but are they finally getting closer to becoming a reality?

Meanwhile, the Netherlands is boosting its cycling infrastructure with the world's first solar bike path. The 70-meter-long road is clad with photovoltaic panels that will produce enough energy for three households.
In other renewable energy news, France just broke ground on the largest solar power plant in Europe, and Scotland generated 126 percent of its household energy needs with wind power last month. French-Dutch company Cloud Collective has installed an urban algae farm on an overpass in Geneva. The algae feeds on exhaust from cars on the highway below, transforming the CO2 into energy. As the world becomes more mobile, portable energy solutions are sure to be the next frontier in renewable energy production. The company Lightning Packs LLC has created an electricity-generating backpack that produces energy via kinetic movement. The energy-generating backpack is intended for soldiers and disaster-relief workers operating in remote regions. And communities around the world are kicking fossil fuels to the curb -- the birthplace of fracking just banned fracking; a Wisconsin coal plant is being transformed into a green arts college; and the Danish government has announced plans to wean itself off of coal within 10 years.
