Three small systems showing probable room-temperature superconductivity
  I shall discuss three small systems in which I think room-temperature superconductivity has been observed. These are: 1. Narrow channels through films of oxidised atactic polypropylene (OAPP) and other polymers. 2. Some multiwalled carbon nanotubes or mats of nanotubes. 3. Sandwich structures based on CdF_2. The main emphasis will be on polymer films.
