Of course the other clues to half the wits that are buying in today. Are:
1. There was no mention in the very recent half year of any progress on the Volvo project. In fact no real progress of anything. 2. Inspirit previously said they would be testing their proposal over the next 12 months which MAY lead to an actual test using a Volvo engine. The time-line is way way to advanced to be associated with this Volvo engine. 3. If Volvo has has released information why hasn't Inspirit ?
So you are all buying on some very poor assumptions and thus the price will fall just as quick as it rose. Who will be caught out ?
The share price increase is presumably based upon the news of this Volvo waste heat recovery engine and everyone thinks it's related to Inspirit. But note that this is a mechanical recovery system probably based around a turbine type system. If you think Volvo has slapped an Inspirit 350 kg Stirling under the bonnet you are very very mistaken. Time will tell
Far from trivial, I think if you look through my old posts you'll find I mentioned that Volvo were researching their own waste heat recovery systems. I think I also said they had more money and more IQ to achieve their aims. If you think Inspirit have a hand in this Volvo engine you are mistaken.
Oldblue: if I recall correctly you claimed the weight of the Stirling was due to the weight of water and you delighted in explaining the difference between dry and wet weights. I pointed out there is very little water in a Stirling engine as is there for a combi boiler. Water flows through both devices and isn't stored hence the weights aren't much changed between dry and wet.
Now, from your typically incoherent replies, you appear to be saying the Stirling attached to a D13 is operating on flue gases. That would be the hot end sorted ! But can you explain how the cold end of the Stirling is kept from heating up to the temperature of the hot end thus resulting in 0% efficiency of the Stirling, rendering the device useless ?
“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%
and CH or chris hemminyway still hasnt sold his shares yet not one......remeber him hes still there....and theres a group camped on board bashing it.....it may get over the line it may not....its AIM theres risk...dyor and GLA
Old blue: You fail to mention I said I was a psychiatrist, I think I failed to get my little joke across or being less harsh on myself, once again you failed to understand!
I shall continue to write negatives for this company since it continues to fool investors. It does not issue share price changing information that could change the price for the worse but continually pumps the price on the plus side while never achieving anything stated in RNS. This is indisputable FACT that any one can read from the RNS statements going back YEARS. You support JG and NJ in this endeavour, giving you the benefit of the doubt, I'll say because you have too much invested and can't bear the thought of being duped and losing your money.
The company have stated they will not produce the Charger, this was obvious to me and others many moons ago. What do you think they are going to make a fortune with now ?
The company has no technical capabilities or ambition to achieve such in a very competative changing world.
The recent total lack of updates on the many projects that are supposedly in progress justifies and validates ( thanks to In-Spirit) my negative comments.
What of the 300 kW project that was being worked on one year ago ? What of the Solar, marine and auto division projects that schematics had been produced. I guess all that had been produced was some rough sketches to prevent the statements being lies.
Marcal: Before you test something you have to design and then build a prototype. In-spirit went to Volvo with a proposal, nothing more. Since they were unable to produce a commercial product from an existing prototype in 10 years then it is extremely unlikely John Gunn can produce any device of use to Volvo. He bought the Stirling engine from the failed Disenco thinking it was a breeze to raise some money and produce a novel best selling piece of engineering. He penny pinched and had no vision or experience. Producing world class technology is not easy, especially Stirling heat engines. Ask yourself, after 200 years why can't I buy a Stirling mCHP for my home? My advice, you need to read more and think more.
