Mr.K.R.Sridhar, an Indian born Ph.D.
used to work for NASA to develop
technologies to sustain life on Mars. His
company, Bloom has been working for a
decade to produce the Bloom Boxwhich was officially launched on 24 FEB
2010.
WHO INTRODUCED THIS INNOVATIVE
IDEA ?
STRUGGLE FOR GREEN

About Bloom Energy:- (power plant in a box)
Bloom Energy is a provider of breakthrough solid oxide fuel
cell technology that generates clean, highly-efficient power
onsite from virtually any fuel source(from natural gas to a
wide range of biogases). Bloom Energys mission is to make
clean, reliable energy affordable for everyone in the world.
The Bloom Energy Server is currently producing power for
several Fortune 500 companies.
The company says that its first 100 kW Bloom Energy Servers were shipped
to Google in July 2008

What is an Energy Server?Built with our patented solid oxide fuel cell technology, Bloom's Energy
Server is a new class of distributed power generator, producing clean,
reliable, affordable electricity at the customer site.
Each Bloom Energy Server provides 100kW of power.

There are similarities and differences between PEM and SOFC
technology
Proton Exchange Membrane (PEM)
Polymer electrolyte
Proton-conducting electrolyte
Low temperature (~100C)
Requires H2 fuel
CO is a poison Needs good reforming/separation
Precious-metal catalysts
Low thermal inertia
Fairly mature
SolidOxide Fuel Cell (SOFC)
Ceramic electrolyte
Oxygen-ion conductor
High temperature (~700C)
Can use hydrocarbon fuel
CO2 is not a poison May use reforming or CPOX
Inexpensive catalysts
Large thermal inertia
In development

Bloom allows you to save money first. The efficiency built into Bloom's fuel
cell systems allows a typical customer to achieve a 3-5 year financial
payback making it an easy and economically sound choice. But the
economics aren't the only story. Customers can also cut their
CO2 emissions by 40%-100% compared to the U.S. grid (depending on their
fuel choice) and virtually eliminate all SOx, NOx, and other harmful smog
forming particulate emissions.

More Benefits & Applications
Power for every individual house with less cost. Unlike Fuel cells they can withstand high temperature
Hydrogen Production and Non-polluting way of generation.
To save money, the Bloom Energy Server uses inexpensive
metal alloy plates for electric conductivity, where as in fuel cell
platinum is used for electric conductivity.

Closing thoughts:-
Let us hope this technology will be availableto ordinary customers with more efficiency
And reduced costs.
And also with the implementation ofBloom energy
we can make sure that our Environment will suffer less.Twenty percent of the Bloom Energy Server cost savings
depend upon avoiding transfer losses that result from
energy grid use.
