"Spell-Check" wouldn't have caught this
DAVID - paragraph #3 -
"Flow-to-Wire recovers energy by mimicking the pressure reduction valves (PRVs) that are used to relief excess pressure in water supply systems. Excess energy is recovered rather than being dissipated as heat."
should be "relieve" .
Unfortunately, I agree with Hates Idiots - I don't believe the cost of the infrastructure will be recoverable by the electricity produced.
