The Bloom Energy Box is a solid oxide fuel cell (SOFC) system that generates electricity on-site with no emissions. It was invented by Indian scientist K.R. Sridhar to produce oxygen on Mars, but was later adapted to provide electricity. The Bloom Box stacks individual SOFCs together to produce enough electricity to power the average home. It draws in oxygen on one side and fuel like natural gas on the other to create a chemical reaction producing electricity with no combustion. Current customers of the Bloom Box include Google, Walmart, FedEx and Staples, providing benefits like lower costs, sustainability and simple installation compared to traditional power generation.

2. Introduction
 Bloom Energy has created an innovative technology
that can change the way the world generates and
consumes electricity
Conventional Power
distribution Bloom Energy Box

3.  Bloom Energy says its
power-plant-in-a-box
produces clean energy
at low cost for
homeowners
eventually to generate
their own electricity.

4. What is the Bloom Box?
 a collection of fuel cells, skinny batteries that use
oxygen and fuel to create electricity with no
emissions
 made of sand that is baked into diskette-sized
ceramic squares and painted with green and black
ink

5.  The fuel cells are stacked into brick-sized towers
sandwiched with metal alloy plates
 The Bloom Box consists of these fuel cell stacks that
are housed in a refrigerator-sized unit
Contd………..

6. How does it work?
 Oxygen is drawn into one side of the unit,
and fuel (fossil-fuel, bio-fuel, or even solar
power can be used) is fed into the other
side
 The two combine within the cell and
produce a chemical reaction that creates
energy with no burning, no combustion,
and no power lines

7. CH4 (fuel )

8. Power Capacity
 Each Bloom Energy fuel
cell is capable of
producing about 25W...
enough to power a light
bulb.
 For more power, the size
of a brick, is enough tthe
cells are sandwiched,
along with metal
interconnect plates into a
fuel cell "stack". A few
stacks, together about o
power an average home.

9. Who invented???
 Bloom Box is the
invention of Indian
scientist Mr. K.R Sridhar
who is working at
NASA for Space
research Operations
 The device was originally
invented to produce
oxygen on Mars but
when NASA scrapped
the Mars mission,
Sridhar reversed his
Mars machine,
pumping oxygen in,
instead of making
oxygen

10. Present Customers
o According to Sridhar that first 100 kW
Bloom Energy box were planted to
Google head office in July 2008.
o Other customers with operating Bloom
Boxes are Wal-Mart (WMT), FedEx
(FDX), and Staples (SPLS).
o These companies quietly purchased
Bloom Boxes and have been using
them to produce part of their
electricity for about 18 months.

11. Advantages
 1. Lower cost energy source
 2. Fuel flexible
 3. Sustainability
 4. Increased reliability & scalability
 5. Simple installation & maintenance

12. Disadvantages
 1.Bloom energy is a SOFC featured with
high operating temperature.
 2. The cost of bloom energy is not economic
yet.
 3. Bloom energy server would need to be
cheaper than the existing renewable energy.

13. Conclusion
 Presently it’s mostly used in
America,in future we would like to see
this bloom box in every Indian home.

14. CONCLUSION…cont
 “we always imagine the world
free from energy related
problems such as pollution,
energy crisis, inefficient use of
limited resources , global
warming etc..so let’s use
available energy efficiently
and smartly so that our next
generations can enjoy the real
beauty of mother earth”
