Engineers are coming up with all the options to generate power from solar energy for a long time. This is another example. Check out the super portable cell phone charger from Green-House Japan named GH-SC350. The charger will be able to recharge your cellphone in just 30-40 minutes (max.).

The only catch…the device will currently work with Japanese cellphones, although there are plans to expand the market.
