Benjamin Franklin used a kite to prove that lightning is electricity; The German engineer Stephan Wrage is using a kite to move really big ships. Inspired by two of his hobbies-kite-flying and sailing-Wrage realized that large kites could be used to pull freighters, thereby dramatically reducing fuel costs and producing fewer emissions. His SkySails kits reach more than 3,000 square feet and cost between $600,000 and $4 million, but can quickly pay for themselves-the largest can trim fuel costs by an average of 35 percent. One freighter, the MS Beluga SkySails, recently completed a 14,000-mile transatlantic voyage with a prototype computer-controlled kite, demonstrating potential savings of $2,000 a day in reduced fuel costs. The company looks to equip 35 more ships with kites in the coming year.LEARN MORE skysails.comPHOTO SkySails GmbH & Co. KG

Why mass shootings spawn conspiracy theories
Mass shootings and conspiracy theories have a long history.
While conspiracy theories are not limited to any topic, there is one type of event that seems particularly likely to spark them: mass shootings, typically defined as attacks in which a shooter kills at least four other people.
When one person kills many others in a single incident, particularly when it seems random, people naturally seek out answers for why the tragedy happened. After all, if a mass shooting is random, anyone can be a target.
Pointing to some nefarious plan by a powerful group – such as the government – can be more comforting than the idea that the attack was the result of a disturbed or mentally ill individual who obtained a firearm legally.
