Which DNA Testing Company Should I Use? The answer, as in many areas of genealogy, is it depends. Because different people test with different companies, many of which maintain their own databases of tested individuals, you will achieve the greatest chance of useful matches by either being tested, or sharing your DNA results, with as many companies as possible.
Cogeneration / Combined heat and Power (CHP) Cogeneration (cogen) through combined heat and power (CHP) is the simultaneous production of electricity with the recovery and utilisation heat.
maximum power point (MPP) In photovoltaic systems, the point at which the most possible current is drawn from a cell, and the voltage subsequently drops off. The MPP changes slightly with temperature and intensity of sunlight. Most photovoltaic (PV) systems have power conditioning electronics, called maximum power point trackers (MPPT), that constantly adjust the voltage in order to maximize power output. Simpler systems operate at a fixed voltage close to the optimal voltage.
