> Hello everyone,
>
>
> Would anyone know more about exactly what type of rocks these area?
>
> *''Ms Twine said the rocks only work in the solar-powered Eco Stove, which
> comes with an internal air supply system that helps heat up the rocks.*
>
> *The stove is also fitted with an on-off switch that enables the rocks to
> burn when turned on, and cool and return to their natural state when turned
> off. The stove comes with a radio, phone charger and has two lights.*
>
> *Unlike charcoal which burns down to ash, these rocks can be used multiple
> times without losing their power or texture.*
>
> *Domestic stoves retail at Ush200,000 ($53) together with the rocks while
> a "bag" of the rocks alone sells for Ush35,000 ($9) for domestic use and
> can last up to six months.*
>
> *Ms Twine says since the stove does not emit smoke, those using it are
> protected from indoor pollution.*
>
> *"They [rocks] do not produce smoke, burn for a long time and you do not
> need charcoal anymore," she adds*
