But I don't know for certain. Second, what's a stabilizer? It seems to me that plastic and metal don't mix, but I don't have more then a rudimentary understanding of polymers. I'd think that if they worked well together then we'd have aluminum/plastic pipe; a stronger pipe then plastic, but with the flexibility of plastic.

These involve transportation: both the vehicles themselves, as well as the powertrain. I am presently working hard to do the CAD Model on a variable compression ratio multifuel SIMPLE and libre engine with extremely high efficiency, as well as kickstart an ebike conversion project that will dovetail into a "mobile battery and distributed internet franchise". The multifuel engine is intended for a TRIBRID drivetrain, involving electrolysis during braking instead of damaging batteries (yes, regen damages batteries) then injecting the mixed hydrogen and oxygen into the engine. The processor and EOMA68 have been part of a long term strategy that is just about to take off. However obviously I cannot do everything so have had to stop technical work on the processor whilst getting the engine etc up and running. The purpose of going to TEC University is to see if they are willing to handle some of the projects.

Or definitely boil it. Hmm... boiling doesn't help get rid of lead does it? And people buying bottled water is far from proof of anything (all too often it's the result of heavy advertising from the vendors of bottled water, spreading fear about tap water and avoiding real comparisons of water quality, where bottled water doesn't always shine).

Correct! Bill Ross is the inventor of exactly that. He uses Potassium Hydroxide as a catalyst, and nickel plates with 0.004 in clearance, 2.5v @ 50 A and you get enough hydrogen to add to a family sized car. > You may want to check out using supercapacitors instead, as a temporary > energy storage mechanism, No, because the voltage varies with current, naking it extremely difficult, electronically, to deliver the power back. What the supercapacitors *are* good for is fronting on the batteey packs, directly at the controller. The decreased resistance results in power being first delivered *from the capacitor* which protects the battery from high load. > since they have a very high power rating (in the > range of 1000x batteries) due to not being based on a chemical reaction. > additionally, supercapacitors don't need additional plumbing and don't need > water refills. they also can skip the big energy loss of > internal-combustion engines which are usually less than 50% efficient. Funny you should mention that. Google 6 stroke engine wikipedia https://www.youtube.com/watch?v=IovhYvKpFRQ Patents from 1880 and 1921 show that water flashing to steam when injected at TDC will not only cool the cylinder but will actually do "work". As efficiency is a direct product of temperature differentials, the 2 extra strokes can result in a whopping FORTY PERCENT efficiency improvement.

Funnily enough, the Intel building in Costa Rica happens to be empty at the moment... :) L. -- --- crowd-funded eco-conscious hardware: https://www.crowdsupply.com/eoma68 From lkcl at lkcl.net Wed Oct 30 19:17:04 2019 From: lkcl at lkcl.net (Luke Kenneth Casson Leighton) Date: Wed, 30 Oct 2019 19:17:04 +0000 Subject: [Arm-netbook] travelling In-Reply-To: References: Message-ID: On Wednesday, October 30, 2019, Jacob Lifshay wrote: > > Correct!
