Floons
Buoyant, luminous, parasitic lighting | |
In this modern world we’re continually bathed in a sea of
electromagnetic energy. Radio frequency fields can be
harvested for (small amounts of) power, effectively for
free.
A lovely array of helium-filled balloons bobbles across your
ceiling, lighting your room. They comprise an LED light
source, a helium-filled envelope with a conductive printed
parasitic coil, and a tiny remote control receiver.
No battery required, no wires, no worries.

Hydrogen would be cheaper [+] but slightly more dangerous [++] |

Nice, different levels of buoyancy could map the spectrum in a volume. Biodegradable life span needed though. |

Helium, being so small, is difficult to contain, and leaks out
of any small balloon I'm familiar with within days. |
