wow you getting desperate arnt you....yes 2020 they came to us 2019

The complete duration of the thesis work was carried out at the Computer AidedEngineering department at Volvo Penta, Gothenburg between the period of January2019 to August 2019
note how im providing links to back up anything and your provide nothing but hot air
Oldblue: which engine improved by 20% ???
ild hazard a guess it was done by the......Computer AidedEngineering department at Volvo Penta
and that was 3rd nov 2020 now im going to leave it at that.....unlike STRONG SELL phimx im not telling anyone to buy or sell just posting info it anyones choice when they hit that buy/sell button it completly upto them....i have my shares and am waiting to see who bought the 500k worth on a 2 million mcap company at 30% less the share price with warrants
im off to the pub have a good one all and DYOR check everything out and reasearch everything before hitting that button!!
GLA!!
Oldblue: once again you don't answer. John Gunn's mates bought the shares, they'll make their money for sure because they ain't buying as an investment. All the mug punters will buy them and the initial recipients make their cut. See UKOG for a good dilution story.
Oldblue. Here is my answer to my question,since you are unable to answer.
************
“During the demonstration, the novel three stage heat recycling process increased engine efficiency by approximately 20%, driven by waste heat from e.g. a Volvo Penta D13 series engine. In addition to the efficiency improvement and heat reduction, the WHR system is also expected to have the additional significant benefit of reducing noise”
Which engine? The Volvo D13 or Inspirit’s Stirling ?
Wiki: The D13 has an output of between 375 – 500 HP. Increasing the D13 efficiency by 20% would require additional output of 75 HP for the 375 HP variant. From my school physics book that’s an extra 55.93 kW ( 1HP = 745.7 W)
The Stirling has a puny 6.4 kW output. There is no known 56 kW Stirling, so it can’t be that !
The alternative is the Stirling engine output increased by 20%, so - 7.76 kW.
Thus the D13 efficiency increases by 7.76 kW/279.64 kW = 2.77% - by adding the Stirling.
I doubt Volvo would really give a xxxx that the Inspirit’s Stirling efficiency increased by 20 % when driven by the huge amount of heat from a D13. So the only thing of interest to them is the 2.77% increased efficiency of the D13.
But, the cost ?
The Charger weighs 350 kg, the D13 1182 kg. Thus the Volvo system weight increases by 29.6% for an increase in efficiency of 2.77% and an obvious significant increase in the integrated system financial cost
Volvo don’t seem to get much out of this proposal !!!
That’s not to mention reliability, how long the Stirling engine would last with a large increase in operating temperature to produce the 7.76 kW ??
For the 500 HP the extra D13 efficiency would be 2.1%
nice buy camoflaged as a sell? just under mid price

To me means this will implode , lol out of the blue another fund raise with no product
ok dug up this seems they have been playing with this for a while this is them trying a rankine cycle jan 2019-aug 2019
they came to us nov 2019 just after as it looks they could only get max 6.7% out table 4.10

Thanks oldblue1973 this is a paper based theory and not based on application of any product
Oldblue: Here we go again.....yawn. you wrote

If you care to read my fag packet calculations below, you will see that In-spirit claimed their Stirling produced an additional 20% when powered from a D13. Therefore the D13 output could be increased by 7.76 kW or in percentage terms 2.7%. JUST FOR YOU 2.7 IS LESS THAN 6.7.Now, if you were to argue it was the D13 output that was increased by 20% then it's output needs to increase by 55.93 kW for the 375 HP model. This leads to the conclusion that an In-spirit Stirling rated at 55.93 kW would have to be driven by the D13. Now since the only Stirling In-spirit have is a tiny 6.4 kW device - supposedly, then a totally new totally larger Stirling would need to be designed, built and tested. Since they have failed to achieve that task with the 6.4 kW device they were handed on a plate 10 long years ago, then you can guess my conclusion ..........NO ******* CHANCE.
right STRONG SELL phinx your using rubbish and doubt again now the 6.7% is for the rankine and the 20% is apparently for the stirling and if you cant figure that out all your clacs are rubbish and gibberish as usual ....look good but garbage....end off story...have a nice weekend
i do remeber you trying to tell us that the volvo penta unit would weight circa 3 tons i can find the post if you want (its there look)
please please please dont ever try to design anything....it will fall down or blow up...
and if your as good a pshchiatrist as you are at engineering you have probably killed most off your patients....
Oldblue: Rankine, Stirling totally irrelevant. You were implying because only 6.7% was achievable they came to In-spirit. But, the current WHR system i.e. the Stirling will only give them 7.76 kW a pathetic 2.7% improvement. Let's consider weight and i'll be generous, for 7.76 kW the Charger weighs 350 kg but you don't need the burner. So a wild guess, 250 kg. Now just assuming weight scales with output, then to increase the D13 output by 20% would require a new In-spirit model weighing roughly 2000 kg. That is more than the D13 itself. And no, I'm not suggesting this massive
big thing is who bought the 500k worth find out next week could be good could be bad....next week GLA!!
Stirling goes in the exhaust. Correct my thinking if it's wrong instead throwing insults

well that kinda proved my point below really.....please dont ever....ever...ever...ever try to design something....
Oldblue: and what exactly is wrong with my thoughts ?
Oldblu :You WILL be confused by the message being split accidentally. My last 2 sentence were meant to be.
"And no, I'm not suggesting this massive Stirling goes in the exhaust. Correct my thinking if it's wrong instead throwing insults"
As usual I'll get no sensible reply from you.
1.A 20% increase in output from In-spirit's Stirling, to 7.68 kW, can only improve the 375 HP D13 by 2.7% . The paper you cite, a theoretical WHR proposition, improves efficiency by 6.7%
2. To increase the D13 by 20% requires a Stirling with an output of 55.93 kW, approximately a 9 fold output of the existing in-spirit Stirling. Totally impossible !
It is that simple. Show me I'm wrong !!!!!!!!!!!!
Oldblue: I say you can not show that's incorrect. Put up or shut up !
Dispute the simple calculations, you keep saying it's rubbish well show everyone it's rubbish. Come on son do your worst.
Inspirit were quick to claim the mCHP was successfully trialled by the Carbon Trust. But In the report was not a single mention of the mCHP performance or what their device achieved.
Come on son, you are full of it, spit it out.
Oldblue: where did you get the information that Volvo first approached In-spirit. ?????
Give us the reference.
Come on Oldblue stop sulking, tell the board why my posts are rubbish. Explain why my figures are rubbish. The board is waiting with bated breath.
Come on son give it all you've got !
ok STRONG SELL phimx you first with calcs how can i say your figures are wrong when you dont provide any?

so how did you get the 7.76kw? detalied calcs pls
how did you figure out the burner for the charger is 100kg? detailed calcs pls
and how did you come by the 2000kg unit pls some detailed calcs on that pls
because as i see you havnt given any calcs so how can i explain where you figures are wrong? you have just stated random numbers without anything to back it up so some nice calcs from you pls!!!
