目前中国已是全球最大的氢气消费国，年用量约3600万吨，主要集中于化工与冶金领域，大量氢气来自煤炭裂解产生的灰氢，虽然成本较低，但伴随高碳排放与污染。而绿氢通过电解水制取，全程零碳排，是真正清洁的氢能。
While a Pico board doesn’t have the same architecture that allows FM transmission on regular Pi boards, it has a unique feature: PIO. This allows running programs based on a minimal instruction set independent of the CPU at the system clock rate. A simple program (“turn the pin ON, turn the pin OFF”) can then produce a square wave at half the system clock rate. Pico boards could be overclocked at ~200 MHz, allowing a similar carrier frequency, but the exact frequency cannot be controlled by software in any practical way. This rules out clean FM.
