Nebel making DC Transformer which can enable a worldwide electrical grid and eliminate energy storage for solar and wind power

Rick Nebel used to run the IEC fusion project at EMC2. EMC2 fusion is a promising approach to commercial nuclear fusion. Richard Nebel was interviewed in May, 2009 by Nextbigfuture on EMC2 fusion. Rick left the EMC2 Fusion project a few years ago.

He left for a multi-billion opportunity for a DC Transformer.
∙ Dynamo Drive can be Used to Make DC-DC Transformers.
∙ A Proof of Principle Experiment is Presently Being Built.
∙ With HVDC (High Voltage Direct Current) One Could Make a World-Wide Electrical Grid.
∙ Eliminates the Need For Energy Storage in PV and Wind Systems
∙ There would be less transmission losses than AC
∙ They estimate that this is potentially a $10,000,000,000/year business.
∙ Nebel filed a provisional patent last November.
∙ He is presently building/operating a proof-of-principle experiment
∙ They have signed a deal with the utility Exelon ($20 billion in revenue, $55 billion in assets, $29 billion market capitalization)

In January, Rick Nebel provided a presentation on his development of a DC transformer.

In the War of Currents era in the late 1880s, George Westinghouse and Thomas Edison became adversaries due to Edison's promotion of direct current (DC) for electric power distribution over alternating current (AC) advocated by several European companies and Westinghouse Electric.

AC won solely on the basis that it is easy to move the voltages and currents up and down with AC power using transformers.

This made long distance transmission possible. Although it is now possible to do this with DC power, it is neither cheap nor simple.

Nebel has invented is an inexpensive and simple way to transform (efficiently change the voltage up or down while maintaining the power available) DC voltages and currents.

Instead of using wires and iron cores like AC transformers do, his DC transformer uses a plasma, helical electrodes and an axial magnetic field.

The transformation of the DC voltages and currents relies on newly discovered physics that is based on MHD dynamo behavior.

Tibbar Technologies, Nebel's company, has signed an agreement with Exelon Corporation, a very large east coast power company, to pursue this technology.

They estimate that this is potentially a $10,000,000,000/year business. Nebel filed a provisional patent last November. He is presently building/operating a proof-of-principle experiment (in the back of Village Arts on DP Road) to test this concept.

A 2012 paper describes the basis of Rick Nebel's DC Transformer

Dynamo Current Drive

∙ Velocity BCs (boundary conditions) Show the Same Principle of the Magnetic Field Trying to Align with the Electrodes.
∙ States Are Single Helicity With Significant Radial Magnetic Field?
∙ All Other Modes Are Stabilized By the Flow.
∙ The Stronger the Driving E Field, the Smaller the Radial magnetic Field.



DC – DC Transformers
∙ Dynamo Current Drive is Effectively a DC – DC Transformer.
∙ High Voltage/Low Current Perpendicular to the B Field Yields Low Voltage/High Current Along the B Field.
∙ A Linear Version of This Device May be Usable as a Transformer.
∙ This is the Key Enabling Technology for High Voltage DC Transmission.
∙ If Inexpensive DC-DC Existed in the Early 1900s We Would Have a DC Grid Rather Than an AC Grid.
∙ DC – DC Transformers Are Possible, but They are So Expensive That it Cannot Be Done Economically for Less Than 20 MW.

High Voltage DC

∙ AC Power Can Only be Shipped Economically for ~ 400 Miles.
∙ AC Couples to the Environment Which Causes Losses.
∙ HVDC Doesn’t Do This and Can Even be Transmitted Underground or Underwater with Low Losses.
∙ With HVDC One Could Make a World-Wide Electrical Grid.
∙ Eliminates the Need For Energy Storage in PV and Wind Systems
