2. O Nowadays almost everybody has a smartphone.
Smartphone is a very multifunctional device, that
helps us to communicate with people, do job and
just entertain ourselves.
O Unfortunately smartphone owners will know that
their ‘’battery life’’ is not so long.
It lasts 1 day or maximum for a 3-6 days.
3. O It is a big problem for example, when you
are on a trip and your battery is ‘’dying’’
and you have no opportunity to charge it.
4. Wind battery charger
O I thought about this problem for some
time. Than I understood that some days in
Latvia are very windy.
O I understood that I can make this defect to
an effect.
5. O I thought about invention that will always
help you when your battery is low and it’s
windy. Even 1m/s strong wind could
produce enough energy
6. O It works just like a mini wind generator.
But it makes electric energy only for your
mobile device.
O
Energy
7. O Whenever your smartphone battery is low,
and you are outside, you connect wind
battery charger with your smartphone and
it will charge.
10. Observation:
O Wind battery charger has more
advantages than disadvantages
O It needs only wind to work
O It helps to save a lot of electrical energy,
so it also helps to save your money
11. Conclusion:
I think in future people could use my idea
because it’s very convenient and it will help
many people. It will not cause pollution and
it will not be very expensive.
