Due in part to the limited
growing capacity of urban environments, the two budding inventors created the
Tomato Tower, a small, low-cost computing system that anyone
could use in their homes. Their
invention could potentially allow those in cities or food insecure areas to
have access to nutritious, affordable and sustainable food.
Not only that, but growing food in one's own homes and neighborhoods would
decrease the amount of fresh produce that is transported in a manner which is both
unsustainable and that decreases nutritional value of fresh fruits and
vegetables.
“This project assumes agriculture as a process that
has huge barriers to entry and requires different things, such as being in an
urban environment where people don’t have access to land or equipment,” Michael
explains. “Whereas, anyone could have this type of unit in their home, which we
see as very empowering.”
At the heart of the Tomato Tower is a simple cherry
tomato plant, purchased from a garden center. Colin and Michael created an
organic soil mix placed with the plant in the container or “tower.”
The container is lined with reflective tape to keep the light inside, promoting
photosynthesis with the help of LEDs. The unit can be plugged into the wall and
the plant can be cared for autonomously with the help of sensors. These sensors
record moisture levels, engaging the irrigation process and providing the plant
with the needed amount of daily sunlight.
The unit’s power supply was converted from an old desktop computer. Some of the materials like electrical outlets were
even found in the dumpster, or what Colin describes as “cannibalizing different
items.”
“It’s one of our goals to salvage and reuse as much
as we could for this project,” says Colin.
“It’s part of our belief about our inventions.
Ideally, this would be done with all found items,” Michael chimes in.
Data collected by the sensors is automatically
published online, meaning anyone can log into the website to monitor progress
remotely. It may sound fancy, but the single-board microcontroller and mini
computer are both under $30 each, making the Tomato Tower a budget friendly
option for those who lack outdoor space for growing.
“All you really need is access to power and a
couple square feet of space,” says Colin.
Genius, right? I’m sure you’re wondering how they
came up with the idea for this project. Well, Colin is from New Hampshire and
Michael is from Iowa, which is from where their agricultural interest stems.
Coupled with their interest in sustainability and their ingenuity, the Tomato
Tower is surely just the start of their bright future!
In a sign of the times, the Tomato Tower is on Twitter!
