This group made capacitors out of some chemicals, a DVD-Rom, and DVD-Rom burner. But not just any capacitor...
The centimeter-scale devices would have capacitances in the range of 400 to 1,000 millifarads
Just an FYI: microelectronics typically use capacitors measured in micro
farads. I do realize that supercapacitors have been a thing for several years now, but its still absurd in my mind to see the units go up to full-farads. I'd love to see the full specs of this capacitor. More impressively, the group claims that this style of manufacturing ought to scale down to what semiconductor labs can output. If a normal laser created using a $50 DVD Burner can create ~1farad devices, imagine the possibilities if this process were done at the ~14nm level that modern CPU chips are made.
Needless to say, if their manufacturing process were just optimized slightly, they could be making extremely impressive supercapacitors. Supercapacitors are already receiving a lot of attention in the electronics industry, and a major advancement like this makes things interesting.
I'd expect the typical problems of supercapacitors to remain in effect. In particular, they are high-power low-energy storage devices. Supercapacitors typically can't store hours-and-hours of electricity... but are instead much better suited for either absorbing or unleashing power all at once. IMO, supercapacitor-equipped Solar Panels will smooth out the power-output so that when clouds block out the sun for minutes, the power-output would be more consistent and cleaner.
Or super-capacitor laced batteries can more consistently hold the voltage / current flowing into the battery. A dirty electrical signal can reduce the lifespan of a Lithium Ion battery, and super-capacitors can do a lot to make the voltage more consistent.
The reverse is also useful. Capacitors can trickle charge in slowly, and when a switch is pushed... they can easily unleash all the energy at once. A lot of pulse lasers use capacitors for this purpose.
