Solar lamps to change oil lamps
Oil lamps are still widely used in spite of the fact that they are toxic and not environmentally safe. My idea is to use solar lamps instead of oil lamps. Solar lamps work 6 hours and above; they are available for all people who don't have reliable source of electricity. Solar lamps have changeable solar batteries which are environment-friendly as they are recyclable. Lamps have brightness regulator, they are water- and heat-resistant and can even be used below -4 °F and above 131°F.
