I'm busy trying to figure out what this is useful for.

From what he's saying, they generated 21k excess Joules over the course of a week.  That's the equivalent of .035 watts.  To give you an idea of what this equates to, 1 kilowatt hour = 3,600,000 joules.  Most American homes use in excess of 1,000 of these per month.  So basically if I built 28,500 of these, I could generate 1 kilowatt (720 kWh/month).  Only another 50% more (or 45,000 total!!) before I can power a home at the low end of power utilization in the US.

It would only take me 170 days to generate a kilowatt hour with their system.  This goes to the core of "How useful is overunity?" or, more appropriately, "When does overunity become useful?".

If I had a choice between the Orbo system generating ten times the excess energy that they are and a PV system ($8/watt), the PV system wins, hands down.  Let me state this a little more clearly.  If the entire orbo system costs $10, their current design would be the equivalent of a $285/watt system.  Making it generate ten times more excess energy would make it the equivalent of a $28.50/watt system.  Wind power systems are closer to $1.50/watt.  To make it competitive with those, it would have to generate 100 times the current excess energy.  Now, it's important to remember, that this is based upon the entire system costing $10, which I'm sure it costs a lot more.  Make it cost $100 and now you have to have it generate 1000 times as much excess energy to be considered 'worth it'.

I do want to qualify that I think that overunity is a worthwhile pursuit.  I do wonder when it becomes a system worth actually implementing.  Orbo is maybe a 'first step', if they're actually generating 21k joules worth of usable EM energy (their video seemed to confuse the subject by talking about thermal energy, kinetic energy and joules, etc...), not to mention that they were sitting in an almost perfect situation (magnetic bearings to reduce resistance to a minimum and the like).  When we have to convert it to a less perfect situation, this turns into a neat little (albeit expensive) toy.

So when do you consider an overunity system to be worthwhile?  $2/watt generated?  $10/watt generated?  $100/watt generated?  As a consideration, at $.10 per kilowatt hour, a ten year payback schedule is $8.76/watt.

sounds like 'overunity' could become useful when humanity quits wasting so many kilowatt hours... and starts to understand the difference between needs and wants.

Even your most efficient homes are using hundreds of watts.  Just heating a small home will use hundreds of watts.  A human generates more wattage in heat (125 watts) than 3000 orbos would generate (105 watts).

It's easy to make statements like "Until you can power your home with an Orbo, you're using too much energy", but when I can easily generate 1000 times as much energy as an Orbo would with a 10' square PV system (on a cloudy day), why would I buy an Orbo?  If the Orbo takes up .3 cubic feet in space, I'd need a 10x10x10 room just to host 100 watts worth of energy generation... Why buy them when I can generate that same 100 watts on the cloudy day with PV on my roof (taking up none of my living space)?

Until they can make this generate a LOT more energy, it's looking about as useful as a sixth finger.

Nice catch! Now we know how many watts it produces. Once the science & engineering community proves it, then the rest will be history. It probably won't be long after until it's powering homes.

yes, our most efficient homes are still inefficient... no argument there. and no, you don't need the thermostat set at 75 to survive now do you? it's about your 'standard' of luxury and convenience.

it's easy making statements like "until it can power your home, the orbo is useless" too. i never said wind power, pv, hydro, etc. wasn't better, easier, cheaper, etc... did i? NO. what i said was "sounds like 'overunity' could become useful when humanity quits wasting so many kilowatt hours... and starts to understand the difference between needs and wants." humans don't need kilowatts to survive, we managed just fine for millennia without electricity...

To you, maybe. To a scientist, it will be PRICELESS! One of the greatest discoveries of all time. The first gasoline motor barely ran by itself. The first LED could hardly be seen.

indeed. and only output a fraction of the 'horse power' that it was to eventually replace...

And look how many feet the Wright brothers flew the first time. He he, and now we fly to the Moon, Mars, and space probes at the ends of the Solar system.  :)   And we haven't seen nothing yet!

Maybe... If Steorn doesn't get squashed by the Pythonesque foot of the oil baron first !

If this wasn't a modified electric motor, which we understand pretty well, I would say that we could plan on dramatic increases in efficiency, but this is basically a highly tuned electric motor that barely slides past unity.  To make this usable, they would likely have to be able to scale the effect beyond the very small magnets they are using (if they are producing .035 watts and at 103% efficiency, they are consuming a single watt) and increase the efficiency well above 103%.

As for whether .035 watts is useful... you could capture the wind from breathing and it would probably be more than .035 watts.  I can't express strongly enough how little power this is.  We're not talking "you can't keep your house at 75 degrees", we're talking "If it's 35 degrees outside, this won't bring it up to 35.1 degrees in your house."  We're not talking "You won't be able to run 5 75 watt light bulbs off this", we're talking "You can't run a single candlelight LED off it".

There are any number of systems that would generate more power for the same density.  Photovoltaics is the most obvious, but replacing your floor with power generating pads that produce power when you walk across the room would generate 1-2 watts while you're walking across the room.  Placing similar units on your furniture could generate significantly more power every time you sit down (around 100 joules every time you sit down).  If you sit down 210 times in a week, you'd be doing just as good as the highly tuned Orbo.

This isn't something completely new, it's a pulse motor.  They're not going to take this design and turn it into a 300% efficiency motor (input 10 watts, get 30 watts out).  The fact that they're keeping it at 1 watt in/1.035 watts out tells me that, after 3-4 years of development, they still haven't been able to scale it up from the very small scale they started with.

If usable amounts of energy are going to come from a modification to an electric motor, it's going to be a dramatic change from the standard motor, not just a highly tuned pulse motor that barely gets above unity.

Nah, Big Oil will just allow a few people to put them out of business by allowing everyone on Earth to be energy self reliant. Haven't you been to Texas? They allow people to walk all over them.  ;)   Hey, just kidding. Indeed they're not going to sit back and allow it, but obviously they have to do that behind the scenes, unnoticed. They pay megabucks to look good and friendly.  Although, how would they stop Steorn? If they blow up the building, then it will look obvious, and draw world attention. If everyone at Steorn suddenly dies, then again it's obvious. Maybe Big Oil can stop a garage inventor, but not a company.

By the way, just for electrical energy (not heating or electric
auto) the average US home would be satisfied with a 1.5KW continuous
electrical generator firing into a 26KW (very similar capacity to the
electric automobile battery) battery backing store. The average home
probably has a very low continuous base load, the permanent continuous
use of electrical energy. This is important because, a larger base load
would need to be met by additions to the generator capacity.

While 1.5KW continuous is a lot from a D cell point of view it is not all
that much machine wise. Remember these numbers, 1.5KW and 26KW
as you will be tested on them. :)
