In this video, Donely describes that his first idea was to make a small wind turbine, a product that could power things like cellphones, and that he imagined would ultimately help the economies of third world countries. Then, he decided to better that idea by making an actual inexpensive 3D printer for third-world countries, which could use online designs and readily-available products, like plastic bottles, to mold other elements necessary to make their own products, including things like small wind turbines. There is more about Donely here:

Donely Gunn is headed to Harvey Mudd College in Claremont, California, to study engineering. He is the winner of a Gates Millennium Scholarship.

Next is the other student who went to ISEF, Austin Li, a senior from Greenville, Mississippi. He will attend UC Berkeley to study chemical engineering. For his ISEF project, emails Mr. Bratton, “Austin was investigating how new processes affected various properties of cast iron.” His project there was titled: “Novel Process for Observing Phase Transformations in and Strengthening Cast Iron via Controlled Cooling."

The project Austin demonstrates here here is his Arduino LED Cube, which he built from available online supplies and designs and then programmed to appear to shoot fireworks.

Coby Anderson is the one junior in this group, from Hernando, Mississippi. He will return to MSMS for his senior year next fall. Coby said that he likes building new things, which he usually does every few months. He engineered and built a mechanically-powered grandfather clock out of small plastic pieces. On the hour, a golf ball is released at the top of the clock; it slides down a track, tripping levers that strike chimes. This is his own design and assembly, not based on a kit.

Michael Murphy, a senior from Caledonia, Mississippi, is headed to Mississippi State in the fall to major in mechanical engineering. Michael's project was building a generator to power a bike's headlight. This is obviously a well-known device; what he was doing for the school project was building it himself.

Rhiannon Hancock is a senior from Scott, Mississippi, in the Delta. She will go to the University of Mississippi in the fall to study biology. Rhiannon made a surprise rumbling box. She’ll present the box as a gift; the recipient will take the box and be surprised when it starts to vibrate. She said the lucky recipient will probably be her physics teacher.

Vikram Sachdeva is from Flowood, Mississippi. He is going to the University of Michigan to study electrical engineering. Vikram is making (from online designs and materials) an Ollie, an autonomous robotic blimp (a helium balloon) with little flappable wings attached to it. A microphone picks up a clapping sound, which will signal a mini micro controller to make the wings flap.
