Dooyrt Wendell: "Ta vondeish ec y chorys ain er coryssyn lossreeyn as algaghyn. T'eh orroo ram bree y cheau er obbraghyn elley, dys tannaghtyn bio as geddyn sliught. Fodmayd jannoo shugyr ass ooilley bree ny greiney ta goit ain. Chammah's shen, cha nel feme ain er thalloo mie da'n chesh, myr shen, cha bee eh brishey stiagh er troarey."

Ta vondeish elley bentyn rish co-ghlooghey daa-ocseed charboan. Dooyrt Wendell: "Ayns coryssyn lossreeyn dooghyssagh, ta rouyr daa-ocseed charboan dooney co-haaghey sollys, agh ta'n corys ain er bun bacteyragh. Myr shen, foddee eh goll er ayns çhymbyllaghtyn as ram daa-ocseed charboan ayndaue, myr sampleyr, smoghan stashoon lectraghys geayil."

Ta ymmodee vondeishyn da croo kesh gollrish lus.

"Foddee oo jannoo ram stoo ass ny shugyryn, myr sampleyr, ethanol as bea-chonney elley," as Wendell. "As t'eh goaill daa-ocseed charboan ass yn aer, gyn anveaghey thalloo banejagh."

Dooyrt Dean Montemagno: "ta'n çhaghnoaylleeaght shoh taishbyney saase spaarailagh dy yannoo ymmyd jeh fyshoaylleeaght vioagyn, liorish croo sheeloghe noa dy stooghyn obbragh ta covestey obbraghyn bea 'syn troggal oc.
