All the world scientists are in a search for the technology that provides a cleaner, more reliable, and more affordable alternative to both today’s electric grid as well as traditional renewable energy sources. They want the technology to provide distributed power generation, allowing customers to efficiently create their own electricity onsite.
It must be built using abundant and affordable materials. The technology must be fundamentally different from the legacy traditional technologies and most people must become familiar with it.
Technology must be distinct ways like:
1. Low cost materials –Must use a low cost metal instead of precious metals.
2. High electrical efficiency – Must convert fuel into electricity at nearly twice the rate of some legacy technologies.
3. Fuel flexibility –Systems must be capable of using either renewable or fossil fuels
4. Reversible –Technology must be capable of both energy generation and storage

Distributed generation (DG) refers to power generation at the point of consumption. Generating power on-site, rather than centrally, eliminates the cost, complexity, interdependencies, and inefficiencies associated with transmission and distribution. Distributed generation shifts control to the consumer. The World Needs Distributed Generation that is Clean and Continuous. Historically, distributed generation meant combustion generators (e.g. diesel generators). They must be affordable, and in some cases reliable and clean. While many people will tolerate dirty generation thousands of miles away from them, they think twice when it is outside their bedroom window or office door.
Recently, solar has become a popular distributed generation option. Although the output is clean it is also intermittent, making it an incomplete strategy for businesses that need power around the clock, including when the sun is not shining.

Bloom Box was developed by California based company named Bloom Energy started by Indian K R Sridhar. He completed his degree in Mechanical Engineering from NIT Trichy and moved to US in 1980s. He completed his master’s degree in Nuclear Engineering and PhD in Mechanical Engineering from the University of Illinois, Urbana-Champaign. He started Bloom Energy in 2002. Prior to founding Bloom Energy, Dr. KR Sridhar was Director of the Space Technologies Laboratory (STL) NASA and at the University of Arizona where he was also a professor of Aerospace and Mechanical Engineering.

In October 2001, K.R Sridhar C.E.O of BLOOM ENERGY had a meeting with John Doerr from the large venture capital firm. Sridhar was asking for more than $100 million to start the company BLOOM ENERGY. But BLOOM ENERGY has received $400 million of start-up funding
from venture capitalists.



INTRODUCTION Technology to generate electricity closer to wher e it is consumed  Must save money ,increase dependability & pr otect the environment  It must meet ener gy demands mor e dependably,affordably & sustainably, 24/7  ©Lova Raj

AN IDEA K.R.Sridhar fr om INDIA ,Pr ofessor & A dvisor to NA SA Developed the IDEA for Bloom Ener gy Reverse Engineer ed a device,that creates OX YGEN to astr onauts Instead giving OX YGEN, device uses OX YGEN to pr oduce ELECTRICA L ©Lova Raj

K.R.Sridhar Professor & Advisor to NASA ©Lova Raj


SAND  The first main component used in Bloom Energy is SA ND  From the sand FUEL CELLS are prepar ed ©Lova Raj

FUEL CELL Bloom's fuel cells – flat, solid ceramic squares  Made fr om a common sand-like "powder."  25w of energy  ©Lova Raj

STACK A ll these fuel cells are tightly packed to make a STA CK  Material used ar e less expensive than metals currently used  1kw of ener gy  ©Lova Raj

METALIC BASE  Fuel cells are coated with META LIC-BA SE  ©Lova Raj A llow ELECTRICITY to pass thr ough system

MODULE A ll the stacks are combined to MODULE 25kw of energy  ©Lova Raj

SYSTEM  A ll these modules ar e again combined to form SYSTEM  100kw of ener gy ©Lova Raj

SOLUTION   A nd the system lastly combined to form a SOLUTION 100kw-1mw of energy ©Lova Raj
