💧 تولید برق از بارون؟ بله! تکنولوژی جدید با کارایی ۱۰۰هزار برابر بهتر!

▪️دانشمندای کره‌ای روشی ساختن که با بارش بارون میشه برق تولید کرد؛ اونم خیلی مؤثرتر از روش‌های قبلی. این فناوری با استفاده از لوله‌های باریک و یه پلیمر خاص، حتی با بارون سبک هم جواب میده.

▪️نحوه کارش جالبه: وقتی قطره‌های بارون از داخل این لوله‌ها رد می‌شن، اختلاف بار الکتریکی ایجاد میشه و همین باعث تولید برق میشه. جالبه بدونید این سیستم می‌تونه فقط با قطره‌های کم، تا ۱۲ تا چراغ LED رو روشن کنه!

- هزینه ساخت پایین
- مناسب حتی برای مناطق خشک
- بدون نیاز به توربین، سد یا سوخت فسیلی

+ طبق ادعای تیم تحقیقاتی، این روش تا 100.000 برابر از روش‌های قبلی قوی‌تره. اما هنوز معلوم نیست تو مقیاس بزرگ چقدر عملیاتی باشه.

Telegram Q&A

Q: How does hottg.com work?

Once you've set up a username, you can give people a hottg.com/username link. Opening that link on their phone will automatically fire up their Telegram app and open a chat with you. You can share username links with friends, write them on business cards or put them up on your website.This way people can contact you on Telegram without knowing your phone number.

With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences.

In addition to this, we support end-to-end encrypted voice calls.
