EVIE Keeps Evolving

Hunt Institute Evie

The EVIE project is entering its third phase in the Global Development Lab at the Hunt Institute for Engineering and Humanity. Three years after its first public unveiling at Earth Day Texas in 2017, work on the mobile greenhouse has continued to push the boundaries of innovating a solution to Dallas’ fresh produce problem. The purpose of EVIE is to serve Dallas community members as a sustainable opportunity for fresh produce by encouraging their participation in the harvesting, maintaining, and general operations of a greenhouse.

EVIE’s name was derived from Eve, which is commonly associated with life and beginnings, appropriately matching the Institute’s goals for the project. In 2018, the Department of Agriculture identified 88 separate food deserts in Dallas County. Over half of the food deserts were in three southern portions of Dallas, encompassing close to 400,000 residents. EVIE is designed to be movable through areas lacking fresh produce and easily replicable to increase the availability of fresh produce across the food deserts. The first phase of EVIE focused on designing an easily replicable greenhouse model that could function in recycled environments, including an old, rickety Shasta trailer. In Phase II of the project, researchers from the Hunt Institute examined techniques that could facilitate irrigation, solar access, and temperature controls needed to maintain the greenhouse in any environment.

Before Phase III could begin, the SMU Engineers Without Boards Plant Lab team gave EVIE a much-needed makeover. The roof had a leak. The makeover was completed right before spring break when the COVID-19 Global Pandemic hit the Unites States. Students are working remotely but unable to physically work on EVIE or in Labs as of June 2020. When they are able to return and resume work, Phase III of EVIE plans to make EVIE nearly autonomous to limit work and outside effort required to maintain the greenhouse. To achieve sustainability, EVIE will run off a solar panel to supply power for any water pumping or climate control measures. In addition, a rain collection system will provide irrigation to the individual planters. Through both of these additions to the current mobile greenhouse, EVIE will be able to provide fresh, healthy produce without requiring significant labor or effort on the part of community members.

The findings from this project hope to contribute to the agriculture value-chain development in rural and urban areas by promoting community involvement and educating local schools, food banks, and churches on environmentally sustainable, hydroponic, aeroponic, and vertical greenhouse growing methods.

Applications of Blockchain for Social & Environmental Impact

The Hunt Institute will transform into a conversational hub for computer science, blockchain and social impact during the Hunt Institute Seminar Series on Thursday, February 22 nd.

Xiaochen Zhang, president and founder of FinTech4Good, will discuss the social impact of blockchain. Anna Carroll, a graduate student in the Darwin Deason Institute for Cyber Security in SMU’s Lyle School of Engineering, will join Zhang to discuss the implications of this technology. Chris Kelley, a Senior Fellow in the Hunt Institute, will moderate the discussion.

Before the seminar, Carroll visited the Hunt Institute to explain the use and development of blockchain. She said that blockchain is a system that can be applied to any transaction that should be tracked.

Simply put, blockchain is a system of accountability. If you had to pay a coworker one dollar, it would be smart to pay them in front of an authority figure, for example your boss. That way, the coworker could not later claim that the exchange never occurred. Now, imagine paying that coworker in the middle of a company meeting. Every other employee would be a witness to that transaction. It would be virtually impossible for the coworker to claim that he or she never got that dollar.

Blockchain works in a similar way. By including more people as witnesses to the transaction, blockchain eliminates the risk of a single point of failure.

Blockchain increases in efficacy as the number of users increases. It is better to have 1,000 people using a blockchain than to have ten people using a blockchain. In this system, there is security in numbers. If there are more people invested in the blockchain, there are more people acting as watchdogs for the security of the blockchain. If there was a need for a secure, public transfer, blockchain could be effective.

With both its virtues and challenges, blockchain is an exciting addition to the digital world. Zhang and Carroll will discuss blockchain and its implications at the Seminar Series tomorrow during the 2018 Spring Seminar. Please click here for more information about this event.
