Diminea\u0163a, dup\u0103 ce am dat afar\u0103 din cas\u0103 c\u00e2inii \u015fi pisicile \u015fi am f\u0103cut foc la cazanul din baie, \u00eemi plasez cea\u015fca de cafea pe cartotec\u0103 \u015fi pornesc calculatorul. \u00cendat\u0103 ce am consultat prognoza vremii pe siteul wetter.com, o iau la r\u00e2nd cu \u015ftirile zilei: ard.de, tvr.ro, revista22.ro, agerpres.ro \u015famd.
\nLa televizor urm\u0103resc cel mult programele de \u015ftiri din Germania, care te pun la curent cu ultimele evenimente de pe tot mapamondul (inclusiv cele sportive) \u00een cel mult 20 de minute. La programele rom\u00e2ne\u015fti nu m\u0103 mai uit (a\u015fa cum am mai spus deja<\/a>, de vreo trei ani, de c\u00e2nd o cioc\u0103nitoare ne-a stricat antena de televiziune \u201cnormal\u0103\u201d), pentru c\u0103 m-am s\u0103turat de ele. Pe l\u00e2ng\u0103 faptul c\u0103 sunt extrem de diluate, m\u0103 sc\u00e2rbesc dic\u0163iunea de mahala \u015fi limba de lemn a f\u00e2\u0163elor care prezint\u0103 emisiunile, oportunismul neru\u015finat al redactorilor, b\u00e2lb\u00e2iala agramat\u0103 a politicienilor, subiectele t\u00e2mpe ale a\u015fa ziselor \u015ftiri, care oscileaz\u0103 \u00eentre voyerism \u015fi rom\u00e2nism dulceag, lipsa de profesionalitate… \u015fi multe altele.
\nCititul nu m\u0103 scute\u015fte, bine\u00een\u0163eles, de t\u00e2mpenii. Dar pot s\u0103 diger aceste informa\u0163ii, adesea stupide, \u00eens\u0103 totu\u015fi necesare pentru a r\u0103m\u00e2ne c\u00e2t de c\u00e2t la curent cu situa\u0163ia din societatea rom\u00e2neasc\u0103, \u00een mod eficient: pentru o privire de ansamblu, am nevoie doar de vreo cinci minute. Dac\u0103 doresc s\u0103 aprofundez o tem\u0103, citesc articolele \u015fi consult la nevoie referin\u0163ele date. Dar nu sunt silit s\u0103 v\u0103d tot felul de mutre vulgare \u015fi s\u0103 ascult zgomotele nearticulate pe care le scot acestea. Sunt astfel cel pu\u0163in scutit de \u015focul estetic, dac\u0103 nu \u015fi de cel intelectual.<\/p>\n

Cu generozitatea obi\u015fnuit\u0103, TVR \u00eemi confirm\u0103 prejudec\u0103\u0163ile \u015fi ne d\u0103 mai nou o \u015ftire senza\u0163ional\u0103<\/a>, recicl\u00e2nd o informa\u0163ie<\/a> difuzat\u0103 de ProTV acum un an:<\/p>\n

Pilele Karpen, sistemul produc\u0103tor de energie electric\u0103 f\u0103r\u0103 s\u0103 consume ceva \u00een schimb<\/strong><\/p><\/blockquote>\n

Dup\u0103 acest titlu, care desfiin\u0163eaz\u0103 principiul conserv\u0103rii energiei, autorul schi\u0163eaz\u0103, cu debordant entuziasm, poten\u0163ialul uria\u015f al acestei inven\u0163ii:<\/p>\n

Cine nu a visat la o surs\u0103 de energie inepuizabil\u0103 \u015fi care s\u0103 nu polueze? Care companie auto nu ar vrea s\u0103 \u00eenlocuiasc\u0103 vechile motoare cu unul electric, dar f\u0103r\u0103 acumulatori care s\u0103 necesite \u00eenc\u0103rcare?

Acum \u0163ine\u0163i-v\u0103 bine:<\/p>\n

Ei bine, a\u015fa ceva exist\u0103, aici, la noi, \u00een Rom\u00e2nia, la Muzeul Tehnicii din Bucure\u015fti!<\/small><\/p><\/blockquote>\n

Suntem informa\u0163i c\u0103 acest sistem, o inven\u0163ie care – conspira\u0163ie? – \u201ca stat mult timp ascuns\u0103 \u00eentr-un seif\u201d a fost inventat\u0103 \u201cteoretic, \u00een anii \u201820\u201d, dar c\u0103:<\/p>\n

Cercet\u0103torii de ast\u0103zi \u00eenc\u0103 nu \u015ftiu exact principiul lor de func\u0163ionare care contrazice principii fundamentele ale fizicii, \u00eens\u0103 cel mai important este c\u0103 pilele Karpen furnizeaz\u0103 curent electric de zeci de ani, f\u0103r\u0103 oprire.<\/small><\/p><\/blockquote>\n

Mister total. Inven\u0163ie teoretic\u0103, f\u0103r\u0103 cunoa\u015fterea principiului de func\u0163ionare, dar la care se poate constata contrazicerea unor principii fundamentale ale fizicii?<\/p>\n

Hai s\u0103 \u00eentreb\u0103m un specialist. Cine ar putea fi mai potrivit pentru TVR dec\u00e2t nepotul inventatorului, care ne livreaz\u0103 o explica\u0163ie pe c\u00e2t de inexact\u0103, pe at\u00e2t de agramat\u0103?<\/p>\n

\u201ePilele K sunt un perpetuum mobile de spe\u0163\u0103 a doua. Dup\u0103 p\u0103rerea cercet\u0103torilor de atunci \u015fi chiar de acum, este irealizabil\u0103 dar ea func\u0163ioneaz\u0103 de peste 60 de ani\u201d, a explicat Lasc\u0103r Veniamin, nepotul lui Nicolae Vasilescu-Karpen.<\/small><\/p><\/blockquote>\n

Publicul larg are dreptul s\u0103 fie informat,<\/p>\n

Evident, toat\u0103 lumea se \u00eentreab\u0103 cum func\u0163ioneaz\u0103.<\/small><\/p><\/blockquote>\n

a\u015fa c\u0103 haide\u0163i s\u0103 mai \u00eentreb\u0103m pe cineva:<\/p>\n

O explica\u0163ie c\u00e2t mai aproape de \u00een\u0163elesul comun ar fi g\u0103sit-o dr.ing. Mihai B\u0103dic de la Institutul de Cercet\u0103ri pentru Inginerie Electric\u0103:
\n„Principiul de func\u0163ionare nu se cunoa\u015fte”<\/small><\/p><\/blockquote>\n

Acest lucru odat\u0103 l\u0103murit, ni se dau \u015fi am\u0103nunte, unde inexactit\u0103\u0163ile sunt formulate ceva mai circumspect:<\/p>\n

Se b\u0103nuie c\u0103 ar fi bazat pe extragerea c\u0103ldurii din mediul \u00eenconjur\u0103tor, o combina\u0163ie de electrochimie cu termodinamic\u0103. Din cauz\u0103 c\u0103 func\u0163ionarea acestor pile \u00een mod aproape sigur conduce la ideea \u00eenc\u0103lc\u0103rii principiului al doilea al termodinamicii, au o importan\u0163\u0103 teoretic\u0103 uria\u015f\u0103\u201d.<\/small><\/p><\/blockquote>\n

C\u0103tre sf\u00e2r\u015fitul articolului, se exploateaz\u0103 pu\u0163in \u015fi factorul optimism<\/p>\n

Este foarte u\u015for de imaginat care ar putea fi aplica\u0163iile pilelor Karpen. Laptopuri, tablele(!) sau Telefone(!) mobile care nu mai necesit\u0103 \u00eenc\u0103rcare, sau automobile electrice.<\/small><\/p><\/blockquote>\n

precum \u015fi constatarea trist\u0103 c\u0103 noi, rom\u00e2nii, suntem, o dat\u0103 \u00een plus, nedrept\u0103\u0163i\u0163i<\/p>\n

Ironia sor\u0163ii face ca la un nivel mai jos al Muzeului Tehnic s\u0103 fie expuse numeroase inven\u0163ii ale altor savan\u0163i rom\u00e2ni: primul automobil aerodinamic, construit de Aurel Per\u015fu \u00een anii 20, sau primul aparat de zbor individual, cel realizat \u00een 1956 de Justin Capra. Acestea se adaug\u0103 altor mari realiz\u0103ri rom\u00e2ne\u015fti precum motorul cu reac\u0163ie sau insulina, brevetate de al\u0163ii.
\n<\/small><\/p><\/blockquote>\n

iar totul se \u00eencheie apoi printr-un superb joc de cuvinte, care aminte\u015fte de nivelul intelectual al tabloidelor:<\/p>\n

\u201eRom\u00e2nii au inventat expresia „am nevoie de o pil\u0103” , ba chiar au tr\u0103it \u00eentr-un sistem bazat pe pile, cuno\u015ftin\u0163e \u015fi rela\u0163ii: PCR. Ei bine, acum chiar avem o pil\u0103, \u015fi \u00eenc\u0103 una extraordinar\u0103, cea a lui Karpen. Mai r\u0103m\u00e2ne s\u0103 \u015fi \u015ftim cum s\u0103 o folosim\u201d, spune Cristian R\u0103u\u0163u, realizatorul reportajului.<\/small><\/p><\/blockquote>\n

PS
\nPila Karpen este, a\u015fa cum a afirmat \u015fi inventatorul ei, o pil\u0103 de concentra\u0163ie, care se regenereaz\u0103 \u00een mod continuu prin convec\u0163ie \u015fi absorb\u0163ie de c\u0103ldur\u0103 din mediul \u00eenconjur\u0103tor. Contrazice la fel de pu\u0163in vreunul dintre principiile termodinamicii ca \u015fi un alt perpetuum mobile aparent, orologiul Atmos<\/a>.
\nPuterea ei specific\u0103 este deosebit de redus\u0103, astfel \u00eenc\u00e2t folosirea ei \u00een dispozitive mobile, a\u015fa cum se sugereaz\u0103 \u00een acest articol, este extrem de improbabil\u0103. Instala\u0163ii sta\u0163ionare, care nu necesit\u0103 aproape nici un fel de \u00eentre\u0163inere, pot fi \u00eens\u0103 de viitor.
