Energy-efficient vertical farm to fight food poverty

David Szondy for New Atlas:  Vertical farming has been suggested as a way to bring fresher food to urban dwellers while reducing the carbon footprint needed to grow and transport them, but a group of Carnegie Mellon University (CMU) students sees it as a way to improve basic nutrition in impoverished areas. Using simple equipment and LED lights, the students are developing an inexpensive way to allow almost anyone to grow fresh, nourishing food for their families and community.

There are many kinds of poverty, but one of the most intractable is food poverty. This is because the concept is one of access as much as affordability. In other words, some people may suffer from food poverty because they don't have enough money to buy enough nutritious food, but others, even in very wealthy countries, may live in areas known as nutritional islands. That is, areas where anything beyond poor quality, prepackaged foods is rare and expensive, which results in malnutrition and generally poor health.

To address this, a group of students from the CMU chapter of Engineers Without Borders (EWB), led by Engineering and Public Policy (EPP)/Chemical Engineering (ChemE) undergraduate student Jack Ronayne, has turned to vertical farming as a way for people to grow food in their own homes.

"Something we identified was this idea of nutritional islands in urban communities: places with limited access to fresh food either by distance, freshness, or cost," says Kelvin Gregory, a professor in civil and environmental engineering and faculty advisor for EWB."We asked ourselves: could you simply grow fresh fruits and vegetables in your house? Obviously the footprint needs to be small, so you have to go vertical. And you'll need to use artificial lighting. These are the problems we decided to solve for."  Full Article:

XLamp® XP-L Photo Red S Line LEDs Set a New Standard in Horticulture Lighting

Designed to deliver exceptional efficiency, unmatched durability and seamless system upgrades, XLamp XP-L Photo Red S Line LEDs are optimized for high-performance applications in greenhouses, vertical farms and other large-scale growing operations. These LEDs achieve an impressive typical Wall-Plug Efficiency (WPE) of 83.5% at 700 mA and 25°C. This efficiency allows horticulture luminaires to deliver the same output with less power consumption, translating into lower operating costs and optimized designs that use up to 35% fewer Photo Red LEDs. Cree LED's XP-L Photo Red LEDs, built with advanced S Line technology, set a new standard in sulfur and corrosion resistance, offering an extended lifespan and reliable performance. These features significantly reduce maintenance costs while providing consistent, high-quality lighting throughout critical growth cycles. Additionally, a consistent platform offers easy integration with a drop-in replacement for existing XP-based luminaires eliminating the need for reengineering due to footprint changes. With the same 3.45 x 3.45 mm XP footprint as the XP-G3 Photo Red S Line LEDs, the XP-L Photo Red ensures a hassle-free upgrade for existing designs.
