En fr\u00e5ga som man s\u00e5klart m\u00e5ste st\u00e4lla till en AI motor.

Svaret:

Att k\u00f6ra en vanlig bil en kilometer kr\u00e4ver enormt mycket mer energi \u00e4n vad m\u00e4nniskokroppen producerar. R\u00e4knat p\u00e5 den energi som frig\u00f6rs om vi skulle samla upp och f\u00f6rbr\u00e4nna v\u00e4tet och metanet i dina pruttar, skulle det teoretiskt kr\u00e4vas cirka 6 000 till 10 000 fisar<\/strong> f\u00f6r att k\u00f6ra en kilometer.<\/p>\n\n\n\n

H\u00e4r \u00e4r en uppdelning av matematiken bakom den siffran:<\/p>\n\n\n\n

Energi\u00e5tg\u00e5ng:<\/strong> En vanlig bensinbil drar i genomsnitt 0,07 till 0,1 liter br\u00e4nsle per kilometer. Detta motsvarar ungef\u00e4r 0,6 till 0,9 kWh energi. <\/p>\n\n\n\n

Energi i en fis:<\/strong> En genomsnittlig fis inneh\u00e5ller ungef\u00e4r 100 ml gas (fr\u00e4mst kv\u00e4ve och koldioxid). Den lilla andelen br\u00e4nnbara gaser, som v\u00e4te och metan, ger tillsammans bara cirka 150 Joule (0,00004 kWh) energi om vi eldar upp den.<\/p>\n\n\n\n

Att samla in tillr\u00e4ckligt mycket gas fr\u00e5n magen f\u00f6r att matcha energin i bara en liter bensin skulle allts\u00e5 ta tusentals pruttar, vilket dessutom skulle kr\u00e4va en perfekt uppf\u00e5ngnings- och reningsprocess. <\/p>\n\n\n\n

Ja d\u00e5 vet vi det.<\/p>\n","protected":false},"excerpt":{"rendered":"
