    Can glucose combine with sodium bicarbonate?

    I fell upon an article outlining the general health benefits of a balanced pH, and specific anti cancer benefits. ... both concepts are well supported in published studies. The article then went on to describe a protocol, whereby sodium bicarbonate is dissolved in liquefied honey. The principal...

    What's the purpose of this dual coil?

    What's the purpose of this dual coil? It has a blue and red cable. It stood alone, mounted (isolated) on the chassis of a PC PSU. It's in good condition, so I'm keeping it, but what can be achieved with it?

    DC12V 12A car window motor - what spec for a 220V PSU?

    I have a combined motor and screw drive (to 90 deg). It's original purpose was to convert car windows to electric drive... my guess is that it is at least 25 years old, and made in Japan. For scale... the width of the motor casing is 50mm (as you look at it) I'm making a motorised turntable...

    Is heating oil filtered to produce higher grades?

    Fuel for a paraffin/kerosene inverter heater is sold typically in 20L containers (in Europe). They all claim to be highly filtered to remove odour, and burn cleaner. Customers are also given the opportunity to pay more for different brands, but they all seem to meet the same standards. The...

    When does a 'stated science' stop being a science?

    I recently decided to examine climate science... it wasn't my field, and I had sort of accepted the statements of general scientific consensus of man-made global warming. It really didn't take long at all to become stunned by the intense and immense efforts focussed on data acquisition, only to...

    Rising voltage leak to 100v AC - 220v 50Hz 35uF 1.5KW motors

    I noticed that I could get a minor belt off my 3 x 1.5KW compressor. I attached my meter to a mains supply 'socket earth', and to 'the chassis'. I watched the AC voltage gradually rise... perhaps increasing in speed slightly as the potential difference increased between the chassis and earth...

    Calc L/min air compression to different pressures & temps in my compressor

    I have acquired a new compressor rated at 540 L/min @ 7 bar 150L tank I decided to test this at 23 degC, timing compression at 2 bar intervals (0-2, 2-4 etc.) I was surprised to find that it maintained 34 seconds at each interval up to 8 bar (but this could be poor experimental...

    What breaks down burnt carbon deposits?

    I have an aerosol based 'oven, and chimney cleaning' product. Here are the contents: Aqua Propylene Glycol Butane Ethanolamine Cocamide DEA Propane Sodium Hydroxide Sodium Laureth Sulfate Xanthan Gum Parfum From the list, it appears that the only active ingredient is Sodium Hydroxide...

    What lives in washing machines and eats aluminium alloy?

    The washing machine stopped spinning, so I dismantled it. Here's what I found: I'm thinking it might have become a big battery, as the steel drive shaft was embedded in the alloy drive bracket, which in turn had 6 studs bolting it to the stainless steel drum. It was all enclosed in the sealed...

    I Down convertor 2 photon entanglement - explanation?

    Just watched many times (specifically @ 20:13 - 25:04) Ron Garret's 'Google Tech Talk' All was going well - the 2 photon experiment & concept visualised - only that the finality of comprehension wasn't delivered...... perhaps because Ron was merely using this for his own purpose. This seems...

    Create a dust attracting piece of paper

    I'm looking at equipment that scans an image through a feeder....... evidently dust build up could be a problem. Thinking of a piece of paper, that might attract dust, that could be run through it (I saw a vid of a piece of cleaning paper run through a system - I'm presuming it is 'dust...

    Liquid Na2O3Si: what causes solidification at temperature?

    I have a refractory adhesive based upon liquid Na2O3Si and other unknown constituents. It remains a liquid until a specific temperature..... when it boils, or gasses. At this point, if the temperature is removed (or increased), the liquid becomes a solid. It would appear (perhaps incorrectly)...

    Miscible - acetone in petrol/oil & water?

    This refers to the addition of acetone in petrol and diesel, and the potential action on any water within the fuel. For interest: https://www.physicsforums.com/threads/adding-acetone-to-the-gasoline.366946/ The above provides an interesting live understanding of the benefits to be gained...

    Behaviour of light thru a glass rod 'end to end'

    Pre-amble A glass rod with polished faces. Light goes in one end, and exits by the other end. We hear of light bouncing down fibre optics. What then happens with a glass tube, that has a rough ground inner and outer surface? Or worse..... when a part of the inner diameter is 'hot melt...

    HT 'low current' resistance fundamentals in Tungsten Welder - event horizon

    Does anybody understand the fundamentals of what is happening in this circuit? Tungsten welding info is all about high current..... but this is a low current scenario. AC input, CDI Coil generated 20Kv (estimated) suffers voltage drop over 100mm of tungsten rod. The larger the diameter...

    How to heat the end of copper pipe

    I like the new software....... the email feed was a good idea, and it coincided with an interesting problem I've come up with, that I thought I'd share: A copper pipe: 14mm OD, 12mm ID, 45mm in length, with a 2mm thick x 18mm OD shoulder. The type that comes with a nut, for connecting to the...

    Gravity is std. therefore can we rate a 'mass at height' by watts?

    For example.... wind turbines are primarily listed by their wattage (1.5MW etc.) Presumably their output is varied according to rotational speed, so I'm guessing that the rating is simply a guide. However, for a given mass, at a given height; due to standard gravity, can we state that this...
