IGDC up 400% now LETH on the move caubzjpnywnacxvwf

Wall Street Financial Times Newsletter Specializing in Undervalued Small Cap Stocks for Immediate Breakout We have the #1 track record for our picks in 2004: GETC at .12 Currently .50 High .68 UP 467% TLPE at 1.12 Currently 3.35 High 4.40 UP 293% SWYC at .18 Currently .71 High .81 UP 350% DNYY at .47 Currently 1.42 High 1.85 UP 294% Immediate Investor Recommendation Our Hottest Sales and Earnings Play Projected to Triple in 7 Days: Life Energy and Technology Holdings, Inc. (OTCBB: LETH) Price--- 1.35 Sales Orders Received '03--- over $150 Million +300% growth vs. '02 Est. Sales Growth '04--- +165% Results from latest 10-Q: Total Assets--- 36.8 million vs. 16.8 million Cash--- 23.4 million vs. deficit Shareholders Equity--- 12.0 million vs. 2.2 million Shares Outstanding--- 29 mill Est. Shares in Float--- 7 mill Proj. Value Per Share--- 3.25 -- 3.50 Rating--- Urgent Buy LETH is thriving as an emerging world leader in the conversion of waste materials into electrical energy by utilizing their Biosphere Process System, making them the hottest undervalued stock at this price level where shares are ready to explode on huge investor attention. Sales have rocketed beyond all estimates for LETH with no signs of slowing. The numbers continue to stack-up as sales orders for the Biosphere exceed $150 Million over the past year while the stock price doesn't yet reflect the appearance of these impressive figures on an upcoming balance sheet. We are not the first to uncover this phenomenon as the stock is under accumulation, but we are acting aggressively on this recently filed data. The unique proprietary technology of the Biosphere fills an urgent worldwide need for cost-effective renewable energy sources and a corresponding universal need to solve critical problems in the disposal of waste. The Biosphere System provides the highest level of innovative technology while securing worldwide acceptance for a revolutionary product designed to significantly impact the global waste problem while simultaneously generating electricity. The Biosphere System enables LETH to draw revenue from the disposal of various types of waste at 5 to 7 tons per hour including such materials as: Municipal Solid Waste, refinery wastes, agricultural surpluses or effluents, medical waste, industrial waste, shale oil, sour natural gas, and the huge market of used tires are all converted in the Biosphere Process. LETH also profits from the sale of electricity created from the waste conversion on a continuous basis by generating 5 to 10 mega-watts per hour of electricity which is then sold to replenish the local or national grid. LETH is an alliance partner with Tetra Tech, Inc. (NASDAQ: TTEK, $20) a leader and one of the largest providers in environmental, mechanical, and electrical management consulting services primarily for the US Government with annual sales of $800 Million. Tetra Tech will coordinate permitting, installation and continuous worldwide monitoring of the Biosphere Process System for LETH. Tetra Tech is now in the process of obtaining Department of Environmental Quality permitting for the Biosphere Process in the state of Louisiana. This is a monumental event for LETH which opens the floodgates for major project revenues in Louisiana while having a parallel effect on LETH stock in the form of a huge near-term announcement. LETH has begun to catch the profit-making attention of investors by embracing a major foothold on the global waste problem while a major push for generating electricity from alternative sources continues to be the hot topic due to shortages and massive power failures. LETH contains all the ingredients for major profits as global demand to solve two crisis areas, waste and electrical energy, reaches unprecedented levels. We view this perfectly timed convergence of events as the catalyst for additional contracts that will perpetuate the shattering of the Company's own sales records. We are seeing substantial gains for early investors in a ground floor opportunity that carries our highest rating for short-term trading profits.
