In an attempt to provide affordable hearing to the more than 200 million hearing disabled people in the world, Godisa has developed three hearing aids which use small batteries that can be recharged with a solar powered device.

"Recently Solar Aid changed its name to Godisa in line with the broadening of its product base. Godisa means to do something that is helping others to grow. Its objective is to develop practical technologies for developing countries and to create employment and training opportunities for hearing disabled people." - Godisa.org
