Here's more absurdities from Piper debunked:
Q: Was there any special way by which heating was achieved in Krema II to maintain minimum necessary temperatures for gas-phase HCN?
A: Yes. In both Kremas II and III, heating was achieved by placing bins inside the chambers full of hot coke.
Q: Was the gas exposure time for Kremas II and III the same twenty minutes as per Krema I?
A: Yes. But for these Kremas the gas was removed via mechanical ventilation and was therefore much quicker.
Q: Was there any means of detoxifying the HCN gas before it was vented to the atmosphere?
A: No. It was vented directly to the atmosphere.
There is no evidence for these 'bins'. AND how would these 'bins', allegedly full of smoldering coke, look to those who were allegedly told they were going to receive 'showers'. I guess the evil Germans assumed that the alleged gassees wouldn't figure out that water from showers wasn't compatible with burning coke.
Again, we have HCN allegedly vented rapidly such that the camp staff would be killed. Perhaps only Jews were vulnerable to HCN.
On the 'mechanical ventilation' lie I refer to Germar Rudolf:http://vho.org/GB/Books/trr/5.html#22.214.171.124.4
126.96.36.199.4. Ventilation Installations
Fact: All rooms in crematoria II and III were equipped with efficient ventilation installations.
Incorrect conclusion: Morgues 1 of crematoria II and III were converted into homicidal 'gas chambers' equipped with installations for the intended purpose of evacuating poison gases.
Correct conclusion: It is in fact inconceivable that a large morgue without windows and with only one door filled with innumerable bodies of the victims of epidemic disease would not be equipped with a ventilation installation. The efficiency of the ventilation, however, proves that these installations were designed for typical morgues. The efficiency of the blowers may be seen from the invoices sent to the Zentralbauleitung by the Topf corporation after installation of the systems. According to the invoices, both morgues #1, i.e., the alleged 'gas chambers' (in the invoice designated as the "B-room"), were each equipped with a 4,800 m3/h intake and outlet blower, while for the "L-room" (the so-called "undressing room") only one outlet blower was installed, with a capacity of 10,000 m3/h.
When considering the volume of the two morgues (morgue 1÷504 m3; morgue 2÷900 m3), the results for the alleged, planned 'gas chambers' (4,800/504 =) are approximately 9.5 air exchanges per hour and for the undressing room (10,000/900 =) approximately 11 air exchanges per hour. Does anybody seriously believe that, at the end of May 1943, i.e., two months after the beginning of the alleged mass murders, it was assumed that the 'gas chambers' would need less ventilation than the undressing rooms, or even less than the dissecting rooms, laying out rooms and wash rooms, the ventilation efficiency of which were even greater-approximately 131/3 air exchanges per hour?
Wilhem Heepke's classic work on the construction of crematoria states that a morgue requires a minimum of 5 air exchanges per hour and 10 during intensive use. Thus it is clear that the ventilation installations provided for the morgues were designed, in terms of orders of magnitude, for morgues in intensive use or for morgues containing the bodies of epidemic disease victims. For comparison: Zyklon B disinfestation chambers with circulating air systems were equipped with 72 air exchanges per hour. Furthermore, it should be mentioned that the original plans for a new crematorium in the main camp from 1941-a time when even Pressac admits that the SS had no criminal intentions-provided for 17(!) air exchanges per hour for the dissecting room(!) and the morgues. This exchange rate is considerably higher than what was later realized for all rooms of crematoria II and III, including the alleged 'gas chambers'. Thus, on the way from beneficial planning to (allegedly sinister) construction, the air exchange rates had been drastically reduced (probably in order to reduce costs). Does anybody seriously believe, the SS would have lowered the ventilation capacity when changing the designation of a morgue from a beneficial use to a homicidal 'gas chamber', instead of increasing it? This is thus the final refutation of any argument on the alleged criminal characteristics of the ventilation installations in these crematoria.
