It's not the closed cycle that annoys me (although I think we gain a lot in yield by increasing the pressure, which imposes a closed cycle). What annoys me is that it is not really an external combustion.

Regarding the documentation: on the BNF website, there are some books that evoke the subject. In operation.

Valve lapping is not complicated, I did it when I reassembled the first Honda CG125 4T motorcycle (bought in spare part at a friend whose delivery man had sunk the connecting rod).

With a hand tool (a kind of stick with 2 suction cups, one at each end) and some dough to prowl ... A little attention and elbow grease and it's done.

I know that lapping a valve is not complicated, but:

1 - valve = linkage = camshaft = spring = trimmings: a lot of element for a valve function.

2 - we do not know when to open it: with a valve not mechanically linked to the system, it is easy to test.

It is a detail in the construction of the whole ...

On Gallica (BNF), you can download a very interesting book from RANKINE (but 800 pages).
Each of the engines are well detailed.

yep!
on the other hand a certain flexibility of the valve allows him to flatten himself on the seat. I saw that on the intake valves of a Ford Escort ...
as there is no explosion, we can have very flexible valves, see use engine valves 2T?

Well, I flew over the posts about it, and I came to the conclusion that you're all next to the plate. To know to sell to EDF ...
For storage? Yes, but a UPS and batteries are not that expensive, and if it's a diesel engine powered by HVB recycled, we put 2, 4 or more truck or car alternators, and we recharge the batteries with . We build a control system with automatic start at half load or in anticipation of high consumption and voila.
To make money? We are not on the right site so ... I'm wrong ??

If not, did you see that ??
http://www.dudus-company.com/SOLAIRE/autonomie.htm
go lower in the page, and see the group with flywheel. We must even be able to launch the steering wheel with something other than the engine.

Obviously, it's easier for me since I have the possibility to recover 48V inverters (to use according to the expense) will remain to buy the batteries, unless I can have that are changed for preventive reasons.

I forgot: Why not build a cogeneration group and resell to neighbors, they will be more inclined to withstand engine noise if you sell them KW to 2 cents, right?

Come on, let's stop being personal.
If I could get along better with my neighbor, we would not have each, two meters from the common fence, a cherry tree, a peach tree, an apple tree, an apricot tree, a plum tree, and so on. trees just in joint ownership and everyone would have fruit and more space ... Ditto for high speed internet access, the meter (and the subscription) of water, electricity, etc ...

It is not false!

Olivier, you're right, but look, we live in a profit society.
Individualism is one of the fruits of profit.
"I have this, and you have nothing, too bad for you!"
"Yes, but I have this, and you do not have it"

So, either we exchange it if necessary, that's a civilized behavior.
Or, we praise, that's a profit behavior.

In your opinion, which society do you live in?

And then my vision is simplistic, the truth is more complicated, how to explain that we currently find nothing reasonably priced to achieve energy autonomy.
Especially that there is not a single solution, but a multitude of solutions, more or less good, but solutions anyway.

Without laughing, when we have something that costs cheap, see nothing at all, we are more inclined to lend and exchange.
Mouarf, to help each other, simply.

My opinion is that the people who lead us have everything perfectly well put together, everything is calculated and counted.

Not only is it forbidden (at least in France ...) but then if you manage to sell at 0,02 € / kWh is that you have discovered the water engine or a process with free energy .... with a small engine and fuel (even cheap and if it is free, HVP style of frying, it must be treated what has a cost too) you do not arrive at such a low price.

Otherwise that's why all the inventors of so-called free energy machine who ask for money are all crooks ... because it would be enough that they resell their electricity to finance their development ...

Just a word about the break-in valve, for internal combustion engines, making a break-in valve to recover a seal is not necessarily the right solution. Lapping is a cold breech, as soon as its temperature rises the materials work, and your job is not always rewarded.

For the idea of ​​the lapping valve to the drill the rotary movement, does not correspond to the normal displacement of the valves the reciprocating movement is strongly recommended.
