Can a crystal types radio be made to work in infrared? With an antenna of lead sulfide or lead selenide perhaps?
Can Infrared Crystal Radios Self-Power Like Solar Cells?
Click For Summary
Discussion Overview
The discussion revolves around the feasibility of creating a crystal radio that operates using infrared radiation, specifically exploring the potential use of materials like lead sulfide or lead selenide as antennas. Participants also consider the concept of self-powering devices akin to solar cells.
Discussion Character
- Exploratory
- Debate/contested
- Technical explanation
Main Points Raised
- Some participants propose that a crystal radio could potentially work in infrared using specific materials as antennas.
- Others argue that infrared frequencies are too high for traditional antennas, suggesting that antennas are designed for lower frequencies.
- A participant suggests using a photoresistor-type infrared detector as an alternative to antennas for capturing infrared signals.
- There is a repeated inquiry about the purpose behind wanting to capture infrared, indicating a need for clarification on the intended application.
- Some participants mention the existence of infrared/visible sensitive solar cells, questioning the necessity of capturing infrared specifically.
Areas of Agreement / Disagreement
Participants express differing views on the feasibility of using antennas for infrared and the overall concept of self-powering devices. The discussion remains unresolved, with multiple competing perspectives on the topic.
Contextual Notes
There are limitations in the discussion regarding the assumptions about infrared transmission and the definitions of antennas and their operational frequencies. The scope of the proposed ideas is not fully explored, particularly regarding the practical applications of infrared technology.
