The Cube – New Breakthrough Set to Alter the Energy Landscape Forever

The Cube – New Breakthrough Set to Alter the Energy Landscape Forever

Redox Power Systems has signed a partnership deal with researchers at the University of Maryland in order to develop and bring to commercial market a new distributed electricity generation technology that could change the relationship that many consumers have with the energy market and national grid.

Based on the research of Eric Wachsman, the director of the University of Maryland’s Energy Research Centre, by 2014 Redox will introduce a new fuel cell that is one-tenth the size, and one-tenth the cost of all other fuel cells available on the market.

The new solid oxide fuel cell will provide safe, efficient, reliable power, to households or businesses, both local, and remote, all at prices that are competitive with current energy prices.

Warren Citrin, the CEO and director of Redox, told Forbes that “every business or home should be able to safely generate its own energy. We currently rely upon a vulnerable electrical grid. The best way to decrease that vulnerability is through distributed energy, that is, by making your own energy on-site. We are building systems to do that, with an emphasis on efficiency and affordability. These should be common appliances.”

Redox’s Power SERG 2-80 (a.k.a. The Cube) can be connected to a natural gas supply, whereupon it converts the methane into usable electricity via an electrochemical reaction. It is little larger than a dishwasher, and with no engine and virtually no moving parts, can silently create a constant supply of energy.

Redox boasts that The Cube allows you to “generate your own electricity with a system nearly impervious to hurricanes, thunderstorms, cyber-attacks, derechos, and similar dangers, while simultaneously helping the environment.”

The system is very efficient, operating at 80% efficiency when used to create electricity and heat, and produces virtually no polluting substances, and far less CO2 than other energy sources.

The first models will have a capacity of 25kW, enough to power a moderate grocery store, or a small shopping plaza; but with time Redox will release a 5kW model to power homes, and an 80kW model for larger installations.

Solid oxide fuel cells have always suffered two major problems that have prevented their success in the open market. They operate at high temperatures of around 950 degrees Celsius, and they have cost a lot to manufacture.


Wachsman worked with scores of graduate and undergraduate students over a period of 25 years, speeding millions of dollars of research funding at state of the art laboratories to develop fuel cells that operate at far lower temperatures, generate far more power, and all at just a fraction of the cost.

He explained that they “have achieved major advances in both the composition of fuel cell materials and the micro and nanostructure of those materials. Putting these things together has resulted in a cell that has an extremely high power density, on the order of two watts per square centimetre.”

    That sound really cool but it seems to be marketed as a backup system. So you are protected against the electrical grid but what about if your gas supply is disrupt ? Also to be really attractive, I want to see lower electricity cost then current energy sources.
  • Thomas santilli on August 15 2013 said:
    This is really impressive and a nice advance for home power generation.

    -Marc Sowven, I imagine it will eventually be marketed for remote area electricity generation once more models are in production, one advantage if your gas supply has been disrupted is that you can probably hook up your own gas cylinders, which if you have several should last until the power grids back on
  • marc sowven on August 16 2013 said:
    Thomas, if I have to store gas tanks why not simply buy a standard fuel based generator ? Fuel is much easier to store and has higher energy density. The kilowatt cost has to be really advantageous to attract the market. I sincerely hope it does due to the low pollution of the device.
  • Jorge Bustamante on August 16 2013 said:
    Liquid fuels tend to degrade over time, while compressed gaseous fuels stay good longer.

    Fuel cells are more efficient than generators. If the SOFC is designed properly it can supply electricity and hot water. A nice "bad weather" backup solution for a remote location that may rely primarily on both active and passive solar solutions for heat and power.

    Almost any kind of fuel is more practical than hydrogen for fuel cells in terms of available infrastructure.

    I really don't see any difference between this and the residential systems that have for sale in Japan for the last ten or more years. Nice to see we finally catching up.
  • Nima Sarabi on August 17 2013 said:
    Nice toy, showing that they can make fuel cells work, so thanks but no thanks, make it work on hydrogen instead if you want people to buy and use it. We won't compromise on anything less since the carbon tax fraud.
  • Fiona hayes on September 16 2013 said:
    How much does it cost for 1 that will run a normal sized house,? Can I get 1 shipped to Australia and how much gas consumption does it use, what is the average gas consumption per day..? And where can I buy a energy cube from

    Thanks fiona
  • Paul on September 20 2013 said:
    Sounds great, now show me the numbers.... IE Price of the unit, all these clowns do the same thing... "We have this really awesome really cheap way to fix this issue" Then it's 95,000 to buy one and God only knows how long they will last before they fail.
  • Bill Althoff on February 10 2014 said:
    How much natural gas will it use to create say--25kw... if you get off the grid, are you actually selling energy back to your provider? So the initial cost of the cube plus the cost of the natural gas needs to evaluated against being on the grid and purchase an environmentally friendly back up source. Just curious if there is any data on natural gas usage...
  • Al Thomson on February 28 2014 said:
    If I had one of these running my "Electric" car I could also use it to power my home as needed. Nothing in my home runs without electricity: well, septic, heat/cooling, refrigeration, etc.

    No moving parts = reliable, efficient, minimum preventive maintenance.

    Total cost of wiring, propane take (option), etc. appears doable for my situation

    Cube technology was around 5 years ago. The first to offer residential units will corner the market.They are in use at Google,Microsoft and other silicon valley companies from another manufacturer.
  • michael seegert on February 05 2015 said:
    so my question is, if a facility ( lets say a wastewater treatment plant for example ) that captures its own methane and burns it for power generation, would this be a low emmisions/cost effective switch from generators. They produce their own natural gas along with many others in industry such as landfills etc... and could excess energy created this be fed back into a grid tied system like wind turbines currently utilize?
  • Dave on December 08 2015 said:
    So i had this awesome idea today about a cube that stores energy. My idea actually seems to be a tad bit different but same concept and does not rely on the grid or gas. I googled energy cube and seems that this has been researched and developed pretty far already. Congrats to the inventors and i hope to have one for a very affordable price someday. Eventually, we will be energy dependent all over the globe.
