Altaeros Energies razvija lebde?e vjetroagregate za velike nadmorske visine E-mail

Kako bi iskoristili jake vjetrove koji pušu visoko iznad razine tla, Altaeros Energies je razvio lebde?i vjetroagregat koji izgledao kao kombinacija tradicionalnog vjetroagregata i cepelina. Nakon ve?eg broja uspješnih testova Altaeros je prili?no siguran da bi se njihov koncept mogao koristiti kao opcija za proizvodnju obnovljive energije na udaljenim i odvojenim selima i vojnim bazama.

Dizajn samog Altaerosovog vjetroagregata je jednostavan. Ljuska koja se napuni helijem se diže sa tla na visoku nadmorsku visinu gdje je vjetar puno ja?i nego u blizini zemlje. Lebde?i vjetroagregat se zadržava na mjestu putem vrlo jakih povodaca koji ujedno služe i za isporuku elektri?ne energije na zemlju. Vjetar je na takvim visokim razinama iznad tla i do pet puta ja?i, ali je i puno stalniji.

Tvrtku Altaeros Energies su osnovali stru?njaci sa MIT-a i Harvarda, te su prošle godine testirali prototip veli?ine 10 metara na visinu od preko 100 metara. Taj prototip se automatski dizao na zadanu visinu, proizvodio elektri?nu energiju, te se vra?ao nazad na zemlju. Prototip je na višoj visini proizvodio duplo više energije nego što bi se proizvelo na uobi?ajenoj visini vjetroagregata.

Naravno postoje i druge prednosti ovakvih vjetroagregata, a to je da proizvode vrlo malu koli?inu buke i da je održavanje minimalno, te se može obavljati na razini tla spuštanjem vjetroagregata. Dodatno, ljuska napunjena helijem se nalazi oko lopatica tako da se njihova vrtnja ne može primijetiti, a na što se neki ljudi ?esto žale kod modernih vjetroagregata.

TESTIMONY....THIS SPECIAL PRAYER FIXED ALL MY MARRIAGE AND FINANCIAL PROBLEMS IN ONE DAY CALL +27656842680

I am "Abdu Rhahuman" from UAE, Last year before I met this powerful spiritual healer " SHEIK UMARU", I was unhappy because my wife left me, i tried everything from Healers but nothing seemed to work for me. I wasted a lot of money, Likely I came across two testimonies on google by an old man whose daughter had been saved from drugs and Alcohol abuse, And a divorced lady had reunited with her Ex Husband after 3 years, I made a call to "SHEIK UMARU" and i asked him to help me bring back my wife. He accurately read my future and told me all my problems and why my wife left me before I spoke a word to him. He used a mirror to show faces of people who were trying to pull me down and destroy my marriage. He performed a one day special prayer to clean me from bad luck & also gave me a powerful love spell. Within 3 days of prayers, My Wife confessed everything & asked for forgiveness. My kids are healed and recently got senior job promotion. Are you feeling totally helpless, Heart broken and financially miserable? Is the situation getting worse? Don't lose hope, I have referred many people to "SHEIK UMARU" and He has delivered results for them within a few days....He can help you too!!!! Contact Him on Call/Whatsapp +27656842680
