Sustainable Weather Balloon Wins Student a $10,000 Scholarship

Every single working day countless numbers of climate balloons are introduced all above the environment, employing radiosondes to measure pressure, relative humidity, and temperature. The balloons aren’t environmentally pleasant, though, in portion simply because they’re produced out of nonrecyclable resources these as latex. Also, there’s a whole lot of waste.

Right after a several hrs in the air, a weather conditions balloon bursts and its radiosonde falls to the ground by way of a parachute. Out of the 75,000 radiosondes released each and every year in the United States, only 20 percent are discovered and returned, according to the Nationwide Climate Support. The expense of changing them adds up.


Amon Schumann, a senior at the Robert-Havemann-Gymnasium faculty, in Berlin, has invented eco-welcoming, price tag-powerful methods.

Schumann built a coin-size, photo voltaic-driven radiosonde that weighs 4.8 grams—far much more compact than existing products, which weigh about 96 g. The climate balloon he intended can keep in the air extended than common designs as properly.

His Tiny Radiosondes on a Great Mission challenge was showcased in Might at the Regeneron Intercontinental Science and Engineering Good held in Atlanta.

At a distinctive awards ceremony, Schumann was caught by surprise when it was announced that his undertaking received the IEEE Presidents’ Scholarship. The award was established by the IEEE Basis to accept a deserving pupil for a task that demonstrates an comprehension of electrical or electronics engineering, laptop or computer science, or other IEEE industry of fascination. The scholarship is administered on behalf of IEEE Instructional Functions and is payable over four years of undergraduate university study. Schumann also acquired a complimentary IEEE scholar membership. Susan K. “Kathy” Land, the 2021 IEEE president, presented Schumann with this year’s scholarship.

“In comparison to launching 2,000 to 5,000 balloons that remain up for just two to a few several hours, my balloon can keep up in the air for 52 days.”

Schumann was inspired to make improvements to radiosondes and climate balloons throughout a stop by to a area meteorology museum. There he acquired that radiosondes have not noticeably transformed in the previous 100 yrs.

Environmentally Helpful

Simply because of the boost in air strain at large altitudes, weather balloons burst at around 35 kilometers. To deal with the difficulty, Schumann utilized levels of foil welded jointly, plus a heated Teflon wheel, to make a balloon that is ready to withstand increased altitudes.

“In comparison to launching 2,000 to 5,000 balloons that keep up for just two to 3 hours, my balloon can continue to be up in the air for 52 times, so less balloons have to be introduced,” he states.

His radiosonde offers numerous periods more measurement info for each working day in contrast with classic ones launched each individual two weeks. The radiosondes are outfitted with a solar-powered battery, which is about 20 grams lighter than a lithium battery.

Schumann also created an extension module with a camera to history additional info these as cloud development.

“The digital camera can get aerial photographs of the clouds,” he says, “which allows for a more precise view of their development and connections in comparison to a standard radar method.”

He additional GPS to monitor his radiosonde in actual time. The radiosonde’s place is uploaded to his balloon flight tracker, which he hopes will be of use to those needing temperature data.

The software package he created makes it possible for for the radio weather conditions information packets to be transmitted in genuine time from his radiosonde to an analysis device in his dwelling. The data is then despatched to the Citizen Weather Observer Application, a volunteer-centered community. From there it is forwarded to the Nationwide Oceanic and Atmospheric Administration for possible use in general climate forecasting.

Schumann claims he plans to analyze electrical engineering at a technical university in Berlin.

Brain-Pc Interface

This year’s 2nd-location recipient was Navya Ramakrishnan, a senior at Plano Senior Large College, in Texas. Her interface makes use of mind indicators to comprehensive home tasks such as turning on a tv.

Ramakrishnan’s brain-pc interface was designed for individuals with paralysis and neuromuscular ailments which include amyotrophic lateral sclerosis. She claims her inspiration arrived from the equipment Steven Hawking designed that employed his eye actions to connect.

“That was undoubtedly the starting off position, when I imagined about a way to have a universal interaction-help device for ALS sufferers,” Ramakrishnan says. Instead of utilizing eye movements, she utilized brain waves measured by an EEG headset to gauge action.

She discovered that a spike in the EEG knowledge, a P300 signal, occurs in response to an celebration. Applying a laptop keep an eye on, she designed a visible display of frequently employed home-automation command phrases. The BCI system is linked with the home’s circuit, which controls lights, appliances, and a lot more. The command is carried out by means of wi-fi transmission to the part of the circuit in management of that job.

When buyers see their wished-for command flash on the watch, they depend in their head right up until it stops—which triggers a response and results in a P300 signal. The BCI technique pinpoints which command lit up at the time the signal happened.

“Let’s say the consumer wants to flip on a light-weight. Each time that ‘Light on’ command flashes on the display I talk to them to depend in their head,” she points out. “The counting will deliver that ‘Oh, there’s the mild on command,’ reaction, and it will deliver that spike in the EEG facts.

“Essentially what my procedure does,” she suggests, “is request, ‘Where did these P300 signals happen?’ For the reason that wherever they come about indicates the consumer just reacted to the command that flashed on the monitor.”

Ramakrishnan said she will be attending Harvard this calendar year to pursue a diploma in personal computer science with a concentration in thoughts, brain, and habits.

Detecting Leukemia

Adelle Jia Xin Yong, a junior at Westlake Significant College in Austin, Texas, was awarded 3rd location for her Intelligent Leukemia Labs project. Her moveable microscope and diagnostic instrument properly and speedily detects acute lymphoblastic leukemia.

The creation is compatible with smartphones. An attachment magnifies a drop of blood on a .5-millimeter glass slide up to 1,000 times. An app that uses object detection, impression recognition, and semantic segmentation identifies abnormal blood cells to diagnose leukemia.

Yong says her creation combines her passion for assisting the neighborhood and strengthening accessibility to overall health care.

“In seventh quality I had a good friend who sad to say had leukemia,” she claims. “As I noticed her go by the treatment plans, I questioned how persons who did not have entry to the technologies she had were being ready to get treatments or even a diagnosis.”

Yong’s diagnostic device is focused at all those residing in underserved locations. It fees about US $28 to make and takes advantage of lower-cost resources, most of which can be observed about the residence, these as a metallic pin and a little plastic tube.

When Yong read her name named at the truthful, she was shocked, she states.

“ISEF is a genuinely major issue,” she claims. “I was joyful with my invention, but I did not know I would win anything. I am just unquestionably thrilled.”

Yong’s father introduced her to engineering. In 2020 she taught herself how to code by viewing YouTube video clips.

She started GStar, a club at her higher college that is targeted on empowering ladies in science, technological innovation, engineering, and math fields.

She says she hopes to attend professional medical faculty and develop into a medical doctor. Her goal is to flip her patented prototype into a viable products with the assist of suppliers and labs.
