In only less than a month of its launch, Microsoft announced
that more than 75 million devices worldwide are now running
Windows 10, the latest Microsoft operating system (OS).
Windows 10 launched in 190 countries on July 29 2015, as
a free upgrade to Windows 7 & 8. Microsoft said that there
were 14 million installs within just 24 hours of its release.
Microsoft said its goal was to have Windows 10 on 1
billion devices by 2018. Windows today is used by
more than 1.5 billion users worldwide, mostly on
PCs.
Windows 10 aims to fix the errors made by
Microsoft in its previous version Windows 8,
which was not popular enough either for
individual or business users.

«Yolk Solar Paper»
a solar charger
Korean designer SungWon Chang developed
Yolk Solar Paper, which she called the world’s
thinnest and lightest solar charger. The project
was launched on Kickstarter.
Solar Paper measures just 9 x 19 cm, and is
only 1.5 mm thick, almost as thin as a paper.
It panel weighs only 50 gm. It can easily be
tucked away inside a notebook or clip it to a
backpack.
Solar Paper offers several solar panels, each
panel with 2.5 watt. Panels can be connected
together through their magnetic edges to in-
crease wattage.
In bright sunlight, the two panels can fully
charge an iPhone 6 in about 2.5 hours, and
5 hours on a cloudy day. iPads need four so-
lar panels, i.e. a 10 watt charger to be fully
charged in about 4.5 hours.
