Solar Powered Coffee Roaster

The Hartkops brothers, David and Michael, have built a solar powered coffee roaster that handles 3 pounds of beans at a time. That’s pretty small. But its also pretty cool. And they’re working on one that will roast 30 pounds at a time.

The small roaster is big enough to supply their cafe and internet orders for their all organic and fair trade bean roasting business called, appropriately enough, Solar Roast Coffee. According to an article in Sustainable Industries magazine, they don’t plan to sell the soon-to-be patented machine to other microroasters in the US. Instead, they apparently are intending to sell it to coffee farmers.

    If you feel nervous, get the “jitters” and or can’t sleep when needed
    then coffee may not be for you. While recent studies
    add to the list of benefits associated to a reasonable coffee consumption, many health professionals keep drawing attention on the
    risks linked to an excessive number of coffee
    cups per day. The plant originated in Africa but is now
    grown in over 70 countries.
