What ever happened to Harry from Ryger? I have a personal interest and trying to find out what happened with him or where he is operating from.Originally Posted by Frits Overmars

for all interested: the webinar is about to start (8min).
Edit: turns out the webinar can also be watched afterwards and downloaded as well

Petrol by converting CO2 taken from the atmosphere.
I do not think that BMW this year invested $12,7 million in Prometheus just for fun.

Im hanging my hat on this.
Problem though is the amount of energy required to process, you dont get something for nothing. But then capturing suns energy then storing in a battery is is hardly very efficent either.

Yes..I read in Motortrend that it is about ~60% electrochemical efficiency (maybe can be optimized as everything else) you need 61 KWh electrical energy to get 36,6 kWh fuel. And of course, using renewable energy sources is in the concept as well as it is for electrical cars.
If this works, without to much drawbacks, Greta will like it. And she will perhaps let us continue using our ICE:s. BTW, she appeared in a BMW "ad" a couple of days ago saying BMW is the most environmental friendly car company..
Cheap electrical power is necessary but should be possible under contract at, what, 0,02-0,04 EUR/kWh? Perfect to use surplus electrical power also.
still basking in the glory..
well, got to see this and it enlightened me on the free piston opposed set up....always wondered how a free piston could move something... didn't know that its first combustion stroke is initiated by elastictrickery and it produces no torque and is basically an electrical generator.....but then i don't get out much these days

Just found this video, while looking for something else.
Lots of thoughts for adjustable two stoke exhaust resonant tuning, using temperature management and/or mechanical or electrical controlled diaphragms.

Just read that the engine from the webinar above won 2.6m GBP in funding to go into the next stage (performance validation prototype). It will be combined with passive pre-chamber ignition (like current F1 engines) which should improve efficiency even more.
In times where you can read news about automotive OEMs announcing end dates for combustion engines weekly, that's really good news for petrolheads. And it's a two-stroke! Who would have imagined that

The fact that it is a "real world" test by a major transport company is promising.Just read that the engine from the webinar above won 2.6m GBP in funding to go into the next stage (performance validation prototype).

New innovations only tend to survive when they are considered an improvement by Users who's own money and business success is on the line.

Time to have another hack at the HCCI engine.
No electronics or sparkplug.
No reed or rotary valve
No transfers as we know them, apart from a boost port.
Carburetor throttling/fueling. ceci might appreciate this��
Cast iron bore, because its cost effective.

Went for a ride today with a mate with MC21. Maybe not that clean, but increasingly cool. Smells good.
Need to finish my 500.

It's a 2 stroke....

Hi Flettner.
If you are asking me.
I honestly cannot guess why it is profitable.
If I am wrong and it is not me who is asking, excuse me

Ceci, the plan is to run the A ports direct from atmosphere, no fuel.
B ports have a carburetor (x2) attached, drawing direct from atmosphere. A ports never communicate with the crankcase, B ports, with the carburetors, do communicate with the crankcase when the piston is up (piston port ), as well as direct to the cylinder when the piston is down.
Crankcase feeds the boost ports (x2) so as to get some actual pumping.
In the head will be my short stroke piston running at x2 engine speed, so as to get compression ignition at the right time.
The idea behind this is to hopefully get some TPI like cylinder fill and be able to throttle the HCCI process all with no electronics. For a start anyway, I will soon add some electronic complication Im sure.
Ceci, the lack of electronics I thought you might appreciate.
