That’s right. The next time you go to the bar and order a tall, cold Sierra Nevada (sponsor us!), drink it knowing that it’ll not only get you drunk but also that your efforts are not in vain. The California-based brewing company unveiled an initiative to convert beer waste into ethanol that can be used to power certain vehicles. Yeast, sugar and water are used in conjunction with an EFuel 100 Microfueler. This ensures that nothing is wasted. Get it? Wasted? Just drink the damn beer and be happy.
