Yes, there are very many solar cell phone that are readily available.
They are readily available, but still too expensive for most people to afford.
There are many kinds of energy sources that are available in the Philippines. One of these resources is solar and it is readily available.
I have seen cell phone batteries with solar cells in them, but not in a while. So solar powered phones exist. There is also a pocket-sized product called Solio which opens up into a fan of solar panels and contains a backup battery and power charging cords for cellphones. You just have to remember to leave it in the sun while talking on the phone, since there probably isn't much sunlight in your pocket. (It also comes with a plug-in charging cord, but if you're on the grid, what's the point?)
There are cell phone chargers that are available that run on solar and wind power, which generates electricity.
Lunar mining will need energy. Fossil fuels (coal, oil and natural gas) may not be available on the moon, and, in any case, they will not burn without oxygen. Solar energy is readily available and usable on the moon, as it is on earth.
yes
The energy issues we are facing in the world that would make a solar cooker a viable option for many people include the lack of renewable resources that are available. Wind power and wave power are not as readily available as solar power.

There are several options, due to an increase in technology nowadays. There is the standard micro usb port which is being spread throughout many phone companies, in fact most phones now have this same charging port. There is also the pad where you can just rest your phone on top of it and it charges. Furthermore there is the environmental option which is a solar charger.
A solar cell phone charger is a electrical device, that uses a solar panel to charge a phone battery.
With the appropriate charging unit, any recharegeable battereis can be charged by solar energy.
We can develop technology to use energy sources that are readily available, such as solar energy, wind energy, tidal energy, etc.; and perhaps, eventually, nuclear fusion.
