Naval Postgraduate School Crushes 3D Printed CubeSat for DARPA

CubeSat is a standardized (pdf) set of dimensions for small (10 cm) satellites that are particularly popular with colleges because students can actually test their satellites in space. Normally, CubeSats are made out of aluminum. DARPA wanted to know whether or not a 3D printed CubeSat is a plausible idea. They used their Digital Manufacturing Analysis, Correlation and Estimation (DMACE) competition as a chance to test the idea.

HOpS: the Heliostat Optical Simulation Tool from Google

Google does some off-the-wall stuff, amiright?

One of the many weird-but-useful-in-a-really-specific-way things Google has done is develop software to simulate heliostat arrays around CSP’s…oh it’s also open source.

“The solar power tower is an exciting technology that works by using a field of mirrors, called heliostats, to concentrate the sun’s rays onto a solar receiver on top of a tower. This generates electricity from the sun’s concentrated heat. It’s been successfully demonstrated in the US and abroad at a small scale.” This project is part of Google’s Renewable Energy Cheaper than Coal (RE<C) initiative.

The project overview is here. It looks like these were the people involved in it: Tim Allen, Alec Brooks, Jean-Luc Brouillet, Kevin Chen, Max Davis, Mikhail Dikovsky, John Fitch, David Fork, Zvi Gershony, Dan Larner, Ross Koningstein, Ken Krieger, Ken Leung, Alec Proudfoot, Jon Switkes, Jim Schmalzried, Tamsyn Waterhouse, Bill Weihl, Will Whitted, and Pete Young.

The open source code is here.
