| Headlines like this show the branding power the big schools have.
| If it's one of the big ones the headline is "<School name>

| "Scientists do X", never "Boise Community College students do X".

| You're comparing a research university with a teaching
| college. In respect of a research announcement. Like, yeah
| the College of Western Idaho also doesn't get much PR for
| its football team.

| Neat application though. Obviously, don't expect to buy one next

| electrochemical cells, which are going to scale by volume (cube

| micro-scale applications as the energy harvesting/wireless energy
| schemes people seem to like work on, which mostly scale by
| aperture/area (square law). They treat that in passing,
| basically, the problem with solar is sometime's it's dark, but
| it's not very edifying.
