  1. From the album "Plan-B" (Bi-Energy IH compatible) Prototyping Platform

    In pulse mode "Micro-Bursting" the heat pulse is already buit-up before it modes into a bowl to be flooded by it only while it passes through, little energy at all transfers to this bowl otherwise, which differs significantly from other more popular scenarios...
  2. Salutations, At some point during the spring of 2012 i acquired my very 1st VG pipe, out of curiosity, only to give it away within the week as i recall: i just didn't have the required operator skills! Meanwhile, after only 6 months or so, using an HerbalAire v2.1 table vaporizer (ballons, custom whip) some nuisible side-effects gradually appeared. Eventually i later concluded there was a lack of proper "conditioning", though i remember instead i've actually selected this particular ready-made commercially-available product simply to help promote future easy/convenient replication, e.g. solely based on my preferences for its SiC Core, exactly. Honestly, the Self-Moisturization/Auto-Conditioning aspects only arrived some while after my "Prototyping Platform" experiments started, the year after. Then a succession of trial & error "iterations" took place until i managed to approximately identify a suitable "Sweet-Spot" for my target "Range of Applications" - though i must highlight that doing so equally affected that pipe's fundamentals significantly enough to have a change of its corresponding ritual as well... One old problem i faced was VG's preference for yellow flames: real progress didn't happen as long as i was stuck with this limitation, i needed a radical solution which was to cut into wood and metal in order to shorten the Inlet/Flame-Catcher/Monobloc path ending with my Hybrid Core "Front Puck (removed): The Flame-Catcher (not shown) fits on top, separated by a tiny space inside a wood Sphere. The genuine large VG cavity seemed to result in excess exhaust accumulation threatening to extinguish my blue flame... This is my "4-20" Hybrid-Core configuration: Take note that switching to a blue flame also caused a paradoxical need to move the core structure closer to my cannabic bowl: longer delays promoted worse errors... So that how the new custom-made 17-Holes Metal Disc ends up at the top of the Screw-Base Cavity located right next to the main Core Cavity in the Monobloc, euh... Which means only the larger 3.33 mm thick SiC Front Puck is installed in place of the previous 7.5 mm thick SiC Puck, with its complement parts displaced into that auxiliary cavity. So, the Metal Disc and Top-of-Bowl SiC Puck are slightly smaller in diameter, especially the later as it is wrapped by a screen of brass with a double function: a) shield action by redistributing heat; b) mechanical resilient support. This is the whole finished set (at right) beside an obsolete smoker artifact many decades older (at left): The flexible PVC Extension Tubing provides a "socially-acceptable" feature by promoting "Harm-Reduction" aspects as self-awareness (via direct visual feedback on accumulating condensed water), "Micro-Bursting"/"Micro-Dosage"/"Packetization" of the "Heat Charge", nearly separated "Pre-Heating" and "Vaporization" phases (with adapted inhalation force depending on the presence or absence of potential butane-related by-products), gentle filtration meant to preserve aroma/taste, etc., etc. Here's my "Lava" concept in schematic form, maybe the changes will be grasped more spontaneously: It's a thermal bottle, essentially. In "iddle" state no airflow occurs so the 2 sides made of SiC appear like thermal insulators, while the screen side that was relatively cold turns hot once the aerial stream inside is set in motion. In other words the structure behaves in contrasting ways depending on airflow, which is a transitional event no longer than a few seconds compared to the minutes of other vaporizers. The trick is to use brief/dense heat pulses to pre-heat the core, then the flame is removed, then inhalation can gain in force to begin having real fun... Also note that this configuration should prove readily compatible with Induction Heat combined to Curie-effect alloys for increased precision: temperature and mass of the "susceptor" would then define the amount of replicable "Heat Charge" that can be temporarily stored, etc. Lots of day-dreaming in perspective! The final goal i guess is to vaporize only the surface and not the underlying vegetal substrate under, or avoid "baking", over-heating, whatever, etc., etc. In pure "Plan-A" (Induction Heat) mode there would be no butane to supply super-heated gases (H2O and CO2) but i figure that can be dealth otherwise, since 1 coil can energize more than 1 "susceptor" simultaneously. For example, it would be no trouble having an auxiliary boiler/evaporator besides the main Hybrid Core: Instead of trichomes this one would pre-heat distilled water to feed a moisturizing adjustment valve, etc... M'well, that's it. I've shown what it has become and even what could be awaiting next - too bad the manufacturer doesn't want to be bothered with it! Yet the gain from a moddified version vastly overrides a lack of warranty IMO... Good day, have fun!!
  3. Ian Sample - https://www.theguardian.com/society/2017/mar/01/major-effort-needed-to-make-cannabis-use-less-harmful-say-scientists Scientists are calling for a major effort to make cannabis use less harmful as a rising number of countries look to replace long-standing and outright bans on the drug with more relaxed legislation. A number of countries and US states have softened laws around cannabis use against a backdrop of rising drug potency and an apparent increase in the number of people in treatment for cannabis-related problems. Researchers at King’s College London and UCL said it was now crucial for health officials to consider measures to reduce the harm from cannabis use. Many of the health risks that users face could be reduced by discouraging people from smoking it with tobacco, and using vapourisers instead. In regions that have legalised cannabis, health interventions could target the drug through caps that enforce a limit on the strength of cannabis, and higher taxation on the most potent varieties. Tinkering with the chemical composition of cannabis could also make the drug safer without altering the pleasurable effects users want, they add. Writing in the journal Lancet Psychiatry, Amir Englund and other researchers say that with laws around cannabis rapidly changing, the need to protect users from the most harmful effects has never been greater, while more research is urgently needed to inform fresh drug policies. It is hard to be sure what varieties of cannabis people use and in what amounts because the data tends to be based only on drugs that are seized by the police. But the best estimates suggest that on the global market, cannabis use has on average doubled in the past four decades. In many countries, including the UK, high potency cannabis now dominates sales on the black market. In the past eight years, the number of Europeans entering specialist treatment for cannabis-related problems has increased by more than 50%. It is unclear how many people refer themselves for treatment and how many are sent to clinics by the legal system, but the scientists believe the evidence that cannabis can cause harm to some users is strong enough to justify efforts to make it safer. Several European countries have relaxed their laws around cannabis use, including the Netherlands, Spain and Portugal, and in the US eight states have formally legalised recreational use of the drug. Canada is due to follow suit this year. Many other regions now allow the drug to be used for medicinal reasons. While legalising the drug is expected to cut the costs of cannabis-related crime, it is unlikely to reduce the number of users, the researchers write. “A lot of countries are deciding to change their cannabis policies to more permissive ones and we don’t know whether that will lead to significantly more use and problems, but we do know there are vulnerable groups out there,” said Englund. The main compounds found in cannabis are THC (delta-9-tetrahydrocannabinol) and cannabidiol (CBD). The THC produces the “high” from cannabis, but greater levels of the chemical are also linked to a higher risk of psychosis. There is some evidence that CBD can combat the negative effects of THC, such as poor memory and paranoia, but in high strength cannabis levels of CBD are often minimal. One option the scientists propose is to boost levels of CBD in high potency cannabis, so that users can get their hit without being at such risk of mental harm. “We don’t always have the luxury of waiting for a lot of research and we can sometimes use the scant evidence we have to try and make some kind of best case judgment,” said Englund. “We are fairly confident that higher THC levels in cannabis are not a good thing, and it does seem that higher CBD levels in cannabis are protective, at least to some extent.” Later this year, Englund will launch a study funded by the Medical Research Council to test whether different levels of CBD can reduce the harmful effects of THC. Ian Hamilton, a lecturer in mental health at York University, said the European habit of smoking cannabis with tobacco was the greatest health risk users faced, but this had largely been ignored by public health. He said there was “a real opportunity to minimise such harms by adapting the strategies that have proved to be effective in reducing smoking incidence and prevalence in the general population.”
