A two step approach for making super capacitors from waste wood
Although the specific capacitance was not highly competitive, the total capacitance (4.7 F for 1 cm 2 of one electrode) was much higher than that of common pellet electrodes (about 0.5 F). Finally, technical-economic assessment confirmed the potential for energy saving from an industrial perspective, and a cost breakdown of 4.6 $/kg was …

Can we build capacitors on a PCB board?
The discrete capacitors paralleled with your PCB capacitor can act as one nearly perfect lumped capacitor, giving your fast logic or power design the warm fuzzies. You won''t use a PCB capacitor if you need exact or big values, but you can use it to create a really good power distribution system on your complete design.

8.2: Capacitance and Capacitors
Capacitors are available in a wide range of capacitance values, from just a few picofarads to well in excess of a farad, a range of over 10(^{12}). Unlike resistors, whose physical size relates to their power rating and not their resistance value, the physical size of a capacitor is related to both its capacitance and its voltage rating (a consequence of Equation ref{8.4}.
