Tom’s Demon Challenges the Second Law of Thermodynamics

Authors: Radhakrishnamurty Padyala
Comments: 3 Pages.

This article describes a new demon of the second law of thermodynamics. We name it Tom’s Demon. It acts on lines similar to those on which the famous Maxwell’s demon acts. Tom’s Demon sorts out salt and sugar particles from a mixture of the two without spending any energy. It reduces the entropy of an isolated system thereby reducing the entropy of the universe. and poses a challenge to the second law of thermodynamics just as Maxwell’s demon does.

Farming Liquid Air as Major Energy Commodity

Waste is Simply a Valuable Resource in the Wrong Place. Burning biomass in steam engine for <10% power is just little bit better than wildfire, so here biomass = waste.But burning biomass in my heat engine with Liquid Air/Nitrogen(LA/LN) as heat sink, its efficiency >80%, so here biomass is precious as gasoline, rendering 1kg biomass = 0.5kg gasoline by heat value equality, as per good biomass heat of combustion = 20MJ/kg, gasoline = 40MJ/kg.My inventions could enable the farmed LN as cheap as $0.05/L by proprietary cleantech of fire-for-chill and chill-for-power. Production line:grow energy grass -> burn it in my proprietary heat engine, which consumes LN as heat sink -> shaft liquefaction machine -> produce LA/LN -> feedback 70% LN production to the LN consuming heat engine for rolling-up production -> remaining LN for sale.Burning 1kg biomass in farmland, can produce at least 2kg marketable LN after deduction of LN consumption in situ, as heat sink of heat engine, which is powering liquefaction machine.With 80~90% veneer efficiency, future vehicle drivers need buy both fuel from gas station & LN from nearby farmers or any possible LN retailers for their fuel+LN hybrid vehicles.Even reluctant to give up gas, its demand can be 70% off; e.g. future hybrid vehicle = 15L gas tank + 150L LN dewar, 100MPG, its range = 60L tank gas vehicle.Omnipresent farms = dense ready LN refill & biomass reload infrastructure anywhere, include the remotest rural, better than EV in this point.LN is also excellent energy storage with 10MJ/kg, good for Distributed Energy Resource DER.Where there's energy, where there's vigor; after farmers joins this circular energy economy, there'll be no more hillbilly elegy. The epoch of Farming Liquid Air LA = LN + Liquid Oxygen LO as major energy commodity, and the Cryogenic Heat Sink Revolution CHSR are coming! Are you ready to accept the challenge?
