1. Half of the energy supplied to a typical data center is wasted on cooling electronics, and
2. With 5G there will be an explosion of computing devices at the network edge

Solution: Distributed Computing Networks with LCS Smart Water Heaters

Data processing is undergoing a seismic shift. Ten years ago most companies owned and managed in-house data centers. Today even Fortune 100 firms have moved to the Cloud. With the introduction of 5G, where low latency is key, the model is now shifting to a Cloud/Edge strategy where much of the computing will occur at the edge of the network. In addition, concerns relating to climate change are triggering governmental regulations that favor reductions in fossil fuels, and this has become a key consideration for many end users.

LiquidCool Solutions is a technology development firm centered on cooling off-the-shelf electronics of any shape or size. LCS-cooled IT hardware covers the entire spectrum of computing applications, scalable from the Far Edge to Hyperscale Data Centers, and now has 41 granted and 22 pending patents.

LCS offers a cost-effective ultra-green technology:
 No air conditioning is required
 No water is consumed
 Maintenance is quick and neat
 Dielectric heat transfer fluid has a Global Warming Potential of zero
 Carbon footprint and E-waste are slashed

LCS technology has been extensively tested in the field and lab. Lawrence Berkeley National Laboratory found LCS cooling efficiency to be 30 times better than air cooling in tropical climates, and the US National Renewable Energy Laboratory refers to LCS as the Gold Standard for cooling data centers in connected buildings.

LCS-cooled IT hardware does not need a data center or use water. Computer racks can be installed anywhere there is power and fiber. Furthermore, more than 90% of rack input energy can be recaptured in the form of a 140F liquid to heat water. According to NREL, widespread adoption of LCS technology for cooling data centers in 2016 would have saved 26 terawatt-hours of electric energy, equivalent to 13 million tons of CO2.

LCS has developed a distributed edge computing model based on the Smart Water Heater, a plumber-ready appliance that combines a 50-kilowatt computing rack and 120-gallon hot water storage tank. Instead of installing the rack in a data center, it would occupy 30 square feet in the mechanical room at a hospital, university dormitory, hotel or apartment building, replacing a backup water heater. From a Network Operating Center, virtual machine software would be used to direct computing loads where needed to maintain storage tank temperatures.

A Distributed Edge strategy using LCS Smart Water Heaters could reduce the carbon footprint of a computing rack by 90%, and everyone wins:

Data Center Owner
 Reduce Data Center capital costs and space requirements
 Expand Edge Computing network
 Capital costs are incurred as the community grows

Host Building Owner
 Leverage existing infrastructure
 Reduce water heating energy cost
 Get a free 5G hot spot

    Energy conservation and climate change. My mission is to apply the laws of elementary physics to cool electronics. This is not being done now. Data Centers currently consume 2% of total electric generation, and the need for power is growing rapidly. More than half of that energy is wasted. The technology that LCS developed has the potential to eliminate that waste.

    This might have an enormous impact on climate change. The NREL study stated that widespread adoption of our technology in 2016 to cool US Data Centers could have saved 26 terawatt-hours of electrical energy, which is equivalent to 13 million tons of CO2.
