В Казахстане школьник (9 класс) создал солнечный коллектор. Экспериментальная установка размером 0,33 м² продемонстрировала способность нагревать воду до 30°C и накопить 2 142 000 Дж энергии за день. По словам изобретателя, солнечный коллектор также можно использовать для обогрева сельскохозяйственных и жилых помещений, а также обеспечения горячей водой.

К новости хочется поставить тэг #хорошая_новость и вспомнить, с чего начиналась советская инженерная школа, на достижениях которой десятилетиями вытягиваем нашу промышленность.

Книга "Буду электротехником" издана в 1964 году издательством "Детская литература". "Электроника шаг за шагом" - 2020 год, а "Кружок конструирования" 1989.

Telegram | DID YOU KNOW?

For tech stocks, “the main thing is yields,” Essaye said. On February 27th, Durov posted that Channels were becoming a source of unverified information and that the company lacks the ability to check on their veracity. He urged users to be mistrustful of the things shared on Channels, and initially threatened to block the feature in the countries involved for the length of the war, saying that he didn’t want Telegram to be used to aggravate conflict or incite ethnic hatred. He did, however, walk back this plan when it became clear that they had also become a vital communications tool for Ukrainian officials and citizens to help coordinate their resistance and evacuations. If you initiate a Secret Chat, however, then these communications are end-to-end encrypted and are tied to the device you are using. That means it’s less convenient to access them across multiple platforms, but you are at far less risk of snooping. Back in the day, Secret Chats received some praise from the EFF, but the fact that its standard system isn’t as secure earned it some criticism. If you’re looking for something that is considered more reliable by privacy advocates, then Signal is the EFF’s preferred platform, although that too is not without some caveats. It is unclear who runs the account, although Russia's official Ministry of Foreign Affairs Twitter account promoted the Telegram channel on Saturday and claimed it was operated by "a group of experts & journalists." At the start of 2018, the company attempted to launch an Initial Coin Offering (ICO) which would enable it to enable payments (and earn the cash that comes from doing so). The initial signals were promising, especially given Telegram’s user base is already fairly crypto-savvy. It raised an initial tranche of cash – worth more than a billion dollars – to help develop the coin before opening sales to the public. Unfortunately, third-party sales of coins bought in those initial fundraising rounds raised the ire of the SEC, which brought the hammer down on the whole operation. In 2020, officials ordered Telegram to pay a fine of $18.5 million and hand back much of the cash that it had raised.
