Zenergy Power Plc (LON:ZEN) could be onto something big in the energy sector, says Tom Bulford. The small cap firm produces High Temperature Semiconductors (HTS) that are more energy efficient than copper. As it moves closer to cracking large markets in the US, Tom says the stock has serious long-term potential.

The second had been made by depositing layers of substances that I had never heard of – such as Lanthanum Zirconate and Yttrium – onto a base of textured nickel tape.

Part of Ameriwest’s tertiary recovery program, the South Glenrock plot, contains just under 5 million barrels of recoverable crude, and the potential for about 2.5 million
