Why TwoPointEnergy Technology?

1. The Problem of Waste Heat
 
A US Department of Energy study reports that “Roughly a third of the energy consumed by the US manufacturing industry is discharged as thermal losses to the atmosphere or to cooling systems.”[1] These losses are estimated to be more than 10 quadrillion BTUs – equivalent to the energy of nearly one-fourth of all the oil consumed in the US in 2017 (1.72 billion bbl) or 2.93 trillion kWh (75% of total annual US electric power consumption in 2015).[1-3] Generating this wasted energy has a massive impact on the environment. The US currently produces 63% of its electricity by burning fossil fuels [4], and this combustion results in the emission of approximately 3.84 trillion pounds of greenhouse gases into the atmosphere annually.[5] Converting waste heat to electricity using economical and resilient thermoelectric devices – which have no moving parts and produce no emissions – can help to reduce energy waste, and the production of destructive greenhouse gases.

2. Solar and Geothermal Power-Generation Opportunities


Sunlight concentrated using mirrors and lenses can be harnessed to produce temperatures of 1,000°C/1832°F and beyond [6]. Additionally, geothermal heat sources now being tapped produce temperatures as high as 300°C [7]. TwoPointEnergy's devices are being designed to provide simple, solid-state thermoelectric power-generation solutions that can generate electricity reliably, durably, and efficiently in these elevated temperature applications.
