RANOTOR is founded by the former project leader of SAAB steam engine project during the 70’s. The last years RANOTOR has carried out project together with automotive industry for WHR (Waste Heat Recovery) and Royal Technology University of Stockholm

There are several reasons why it should be well founded to claim that modern steam engine has a huge potential to offer attractive drivetrains for future vehicles.

  • Superior primary energy source flexibility (solar, electricity , biofuel )
  • Can form hybrids with ICE, Electric propulsion and fuel cells
  • Low tail pipe emissions when burning a fuel.
  • Possibility to harness intermittent renewable with a thermal battery
  • Regenerative engine braking
  • High part load efficiency (high average energy efficiency)
  • Low cost (no exotic expensive material and low mass of material normalized to power)
  • Attractive torque characteristic ( high low end torque, elastic torque = increased torque when lowering shaft speed)

    We need industrial consumes to make the installation worth. The Client can install separately the modules in his factory.

    So is it possible to order an E-cat SK unit having a maximum capacity of 20kW thermal for installing in a non-domestic operation.

    Thank you for your insight,

    @Tom Monroe,

    The reason is that there’s a Ballerina inside that makes the difference. And only a little bit of electrical energy is needed to trigger her.

    P.S. Here is a link to the first version of Van Morrisons’ song ‘Ballerina'(On Astral Weeks, 1968):

    Thanks for the demo. As a relative layman (I’m just an IT guy with an electronics technician background), I’m wondering if my untrained observations are a way to help illustrate what was shown in the demo: Most people will understand the amount of heat that comes off of a 1500 watt hairdryer (enough to go from a headfull of wet hair to dry in maybe 5 minutes). What the demo shows is the consumption of about 1/3 the power of a hairdryer, but more than 10 times as much heat. Looking at the critical comments, some of them (specifically those of the flavor of “it’s a heater, meh”) didn’t understand that one type of energy = another type of energy, and it’s impossible to make a more efficient electrical heater because by the first law of thermodynamics, it’s impossible to create (or destroy) energy (IE when you trade electrical energy for heat energy that whatever amount of power you consume, that’s exactly how much you get back).

    Dear Dr. Rossi,
    Dear Andrea,

    May the force be with you.
    May the Mary be Merry.
    Wish you the best of luck.

    Lovingly,

  • Hallo There “jag bara undrar” . My father (Ove Platell) was the Project leader for Saabs steam Engine project but when the catalytic converter emerged and emissions could be improved of the internal combustion Engine it was hard to finance further work on alternative Engines. But my father started RANOTOR Company and now the interest for modern steam Engine has increased again.
    Best regards

    Unfortunately not. But I can say so much that where you have enough heat, it is difficult to get a more economical solution than a steam engine. Why start with the difficult solutions?

  • Andrea Rossi

    “Jag bara undrar?”:
    Can you tell more about it?
    Warm Regards,
    A.R.

    I still remember SAAB’s steam engine experiments in the 1970s. SAAB was / is located in the south-western parts of Sweden in Trollhättan
