Engineers are building solar balloons that float above the clouds for constant sun

Solar farms have been making headlines lately, and solar power options are gaining in popularity as their efficiency levels improve. But a new photovoltaic solution is going to bring solar farms directly to the skies in order to supercharge that efficiency. Since cloud coverage creates uncertainty around the effectiveness of solar farms, why not bring the solar cells themselves above the clouds? Using stratospheric balloons, it may be possible to source solar power...
