Solar Energy Harvesting
« on: May 15, 2017, 11:05:47 AM »
Successfully scaling down a real spacecraft power system to a usable size, especially in an indoor environment is a difficult obstacle to overcome.  Through testing and evaluation of example circuits and various solar cell options, as well as reviewing other users discoveries has left us with a renewed interest in incorporating solar energy harvesting as a viable option for the Cosmoneer.

Back in 2013 when the Cosmoneer idea was beginning to take shape, Solar energy as a power source was the focus for nearly 6 months.  Four years later, we believe we can incorporate ideas presented by others on the internet as a means to successfully power the Cosmoneer (albeit intermittently.)

In this video, Shahriar shares his demonstration of the LTC3105 energy harvesting chip and suggests using two of them in series with a super capacitor in-between.  What he demonstrates is the second circuit harvesting as much usable power as possible from the super capacitor.

As with all things Cosmoneer, the idea is to constrain the Cosmoneer to problems faced by typical spacecraft, only on a smaller scale.
