CREATE TABLE table_4264 ("Material" CLOB, "Type" CLOB, "Geometry" CLOB, "Output voltage" CLOB, "Output power" CLOB, "Synthesis" CLOB, "Researched at" CLOB)

How many materials are there for output power of ~0.1 pw per cycle (calculated)?
SELECT COUNT("Material") FROM table_4264 WHERE "Output power" = '~0.1 pW per cycle (calculated)'
SELECT COUNT("Material") FROM "table_4264" WHERE "Output power" = '~0.1 pW per cycle (calculated)'
