Yoma is a genus of nymphalid butterflies.
Species
In alphabetical order:[1]
- Yoma algina (Boisduval, 1832)[2] (New Guinea and surrounding islands)
- Yoma sabina (Cramer, [1780])[3] – Australian lurcher (widespread from Southeast Asia to Australia)
gollark: Which is as far as I know more an issue of low voltages than DC itself, but DC means you can't change the voltage very easily.
gollark: There is the problem that low-voltage DC loses power more quickly over longer distances.
gollark: Yes, you're right, let's just replace our lightbulbs with idealized magic visible light emitters.
gollark: If they didn't need that (I think the only practical way to achieve this would just be to stick one larger and more efficient converter somewhere) the bulbs would be individually cheaper and probably more efficient too, as well as safer.
gollark: You know something mildly interesting and relevant? LEDs run off lowish-voltage DC. The mains, as connected to most conventional lightbulb fittings (designed for incandescent/flourescent) provides high-voltage AC. This means that every LED lightbulb needs inefficient and probably somewhat expensive power supply circuitry.
