Electric plane designer Joe Doucet

<p>Air travel accounts for about 2.5 percent of global carbon dioxide emissions according to the latest UN figures.  While it’s a smaller share than emissions from passenger cars or power plants -   at least one study shows  plane emissions are growing fast. By 2050, it could go up to 25 percent. Whoever comes up with an electric powered plane would help significantly reduce those growing carbon emissions.  We’re joined by designer Joe Doucet who’s been working on that very idea.</p>
