with shouting neighbors on one side and cof-
fee supporters on the other side, and us in the
middle trying to convince everyone that our
machine wasn’t a ‘death ray.’ In the end, we
have made peace with our neighbors.”
When that obstacle was overcome, the
Hartkops opened a retail coffee shop inside a
historic redbrick building in the financial dis-
trict. Inviting and cozy, the bustling café fea-
tures comfortable chairs, a large, pleasant
patio and a steady stream of customers in and
out of the shop.
The company uses a mix of organic, fair
trade and Rainforest Alliance coffee beans.

“Our roasters retain more of the steam and
smoke produced in the roasting process
because of the way the internal airflow
works,” David explains. “I designed them
that way originally to prevent roaster fires
[a problem with most commercial drum
roasters], but it had the added benefit that it
‘aroma roasts’ the coffee for the full duration of the roast cycle.”
The next Helios incarnation allowed the
brothers to roast up to 30 pounds at a time,
and to expand into a wholesale coffee business that sells to groceries, coffee shops and
restaurants, and even internationally. This
year they launched the Helios 5, moving the
system indoors and incorporating the solar
aspects into a commercial building. When
not roasting coffee, the Helios 5 focuses its
light onto a secondary receiver to generate
electricity and hot water for use in the coffee
As the only direct-use solar-thermal coffee company in the world, Solar Roast Coffee
has been profiled in Popular Science, Food
Network Magazine and other publications.
The brothers plan to use the Helios 5 as a
teaching tool to demonstrate a new way to
power small industry.
“We’re in the process of modifying the
Helios 2 design to be shipped to a Haitian coffee farm as a kit,” says David. “It will let a coffee farm sell roasted coffee for roughly three
times the price of the green coffee they normally produce.
“This system only uses about 35 percent
of the energy of conventional roasting techniques. This is the way of the future!”
