Sustainable Air Transportation

Wright Electric was founded by Jeffrey Mark Engler to solve the problem carbon emissions by airplanes.  Flying is an essential part of modern transportation, but it can triple a persons carbon footprint.  Wright Electric is working on developing an electric airplane that will have much lower carbon emissions than current passenger jets.  The Wright 1 airplane that is in development will be able to carry 186 passengers, and it will use batteries to power electric motors for propulsion.  Lower carbon emissions will be achieved by using electric power and a more aerodynamic design that reduces drag and makes the airplane more efficient.  Battery powered airplanes are becoming more realistic as a result of research by government agencies such as NASA and the Air Force Research Laboratory that are making batteries more efficient and lighter.  An electric airplane has some additional benefits.  Electric motors are much quieter than traditional jet engines, and the decreased use of fuel will make electric airplanes cheaper to fly.  Wright electric is also designing their airplane so that batteries can be quickly swapped at an airport to allow for a faster turnaround time.

Wright Electric has partnered with experienced airlines such as EasyJet, Jetex, and VivaAerobus to get commercial, operational, and maintenance insight during the design process.  The Wright 1 will not have a very large range at first with 500km or 311mi flights from London to Paris, but it will be able to get up a 1,280km or 800mi range.  The Wright 1 will also have slower cruising speeds than similarly sized passenger jets, but Wright Electric expects this to be fine for the short flights that they will be starting with.  Wright Electric is planning to perform ground tests of its motors in 2021 and flight tests in 2023.  They are hoping to have the airplane on the market by 2030.

Allbirds: Eco-Friendly, Minimalist Shoes

As Americans, most of us can say we own one, if not multiple pairs of shoes. For Tim Brown, founder of Allbirds shoe company and former professional soccer player, an over-abundance of shoes prompted his desire for a change in the shoe industry. As Brown progressed in his soccer career, he realized that the numerous shoes he received from his sponsor were “completely unnecessary.” Due to Brown’s experience with an over-abundance of shoes as a soccer player, he let this drive his vision for the Allbirds shoe company. Brown envisioned a shoe that would innovate in reverse. Instead of choosing to add to already technical and detailed shoe designs, he chose to “strip back the shoe and create something simple and natural.” The foundation for Brown’s Allbirds company was one that innovated in reverse. Not only did Brown aim to create a minimalist shoe, but he furthered his efforts by committing to sustainability. Brown continued this vision of minimalism as he chose to use renewable, sustainable resources to build his shoes. For example, Brown and Zwillinger (engineer and renewables expert), crafted a shoe which incorporates eucalyptus fibers containing cooling properties. This creates a running shoe which naturally cools your sweaty feet. Below is a picture of these shoes made from eucalyptus trees.

EVERY part of these shoes are comprised from renewable resources. The laces are crafted from consumer plastics, the insole of the shoe is made from castor bean oil which emits less carbon than petroleum based foam, the mid-sole is made of sugarcane from Brazil, and the upper is made from the eucalyptus tree fiber.

 

The royal crown of Allbirds consists of their use of marino wool shoe material. In continuing with their mantra of sustainability, Allbirds uses marino sheep wool as the majority of their shoe material. In New Zealand, where the company is based and Brown’s home, sheep outnumber humans 6:1. Using sheep wool reduces the use of energy by 60% compared to that of most shoes on the market.

One of the entrepreneurial traits that Brown exudes is passion. It was quite evident through my research of this company that Brown has a profound passion for protecting our earth yet providing style in a simple way. I love how he thought creatively about the simplifying of shoes rather than trying to add to an already very complex shoe industry. By stripping down the shoe to its basic function and fashion, Brown was able to create a product which people thoroughly enjoy due to its performance and contribution to our plant.

“Mother Nature is our muse. Building on her handiwork, we’re finding new uses for materials that exist right in front of us. Like wool from merino sheep, who have the best hair in nature.” – Tim Brown

14 Year Old Finds A New Way To Transport Energy, Wireless?

Vikram Pandian, a fourth grader from Allen Town PA, has created a new way of transporting energy from point “a” to point “b”. Today researchers are learning to use energy from the radio frequency waves all around us that are in the form of cell, Wi-Fi, TV, and radio signals. But to know how effective that kind of system might be, scientists need to know where RF energy is available. Vikram built a Arduino-powered device that measures the ambient RF energy and he also generated a app that creates a heat map. This invention is something that could be used in the future to power cars, homes, mobile devices, computers wierlessly. This could be a global grid that the world runs off of.
