WorldWater & Solar Technologies Changes Name to Entech Solar

FORT WORTH, Texas--(Business Wire)--
WorldWater & Solar Technologies Corp., (OTC BB: WWAT.OB), a leader in
concentrating solar energy systems, announced today that it has changed its
corporate name to Entech Solar, Inc. (the "Company"), effective January 12,
2009. The Company`s ticker will remain "WWAT.OB" temporarily until the Company
is reassigned a new one. ENTECH, Inc. will continue as a subsidiary of Entech
Solar, Inc.

"Entech Solar is a name that more accurately reflects the transformation of our
business since our acquisition of ENTECH in January 2008," said Frank Smith,
Entech Solar`s CEO. "Today, we are a concentrating solar technology company
focused on providing our advanced, cost-competitive modules to commercial and
industrial customers. Entech`s core strategy will be on manufacturing and
selling the company`s breakthrough ThermaVolt product, a combined photovoltaic
and thermal concentrating solar system."

WorldWater & Solar Technologies acquired ENTECH, Inc. in January 2008. ENTECH
has been researching and developing concentrating solar systems for 25 years,
making it one of the most experienced concentrating solar companies in the
industry. Since the acquisition, the Company has dedicated its resources to
commercializing its ThermaVolt system, which produces both electricity and
thermal energy, making it one of the most efficient solar systems today.

"We have seen a lot of solar technologies, but haven`t found anything as
exciting as the ThermaVolt system, which is a true game changer for the
industry. We believe it will be the leader in the combined heat and power
market," said David Anthony, Director of Entech Solar and Managing Director of
21 Ventures.

In conjunction with the name change, Entech Solar has also relocated its
headquarters from Ewing, NJ, to Fort Worth, TX, where its state-of-the-art,
70,000 square foot, 200MW capacity manufacturing facility is located.
