There are those who say that we have waited too long and that if we went to zero GHG emissions immediately, the CO2 and GHGs already in the atmosphere will cause the temperature to rise above the 1.5 degrees C, to more than 2 degrees. So yes, we need millions of machines or hundreds of

This gives some important differences about well to wheel comparisons of BEVs and ICEVs. BEVs are much more efficient. Document (.PDF) is 2.4 MB. https://www.transportenvironment.org/publications/batteries-vs-oil-comparison-raw-material-needs
A few big corporations are monopolizing the energy sector, and causing the US to lag behind when it comes to clean renewables, and maximizing profits at the expense of the consumer. https://www.renewableenergyworld.com/blog/new-report-sheds-light-on-americas-monopolized-energy-sector-and-how-we-can-fix-it/

These are scans of the specifications for most of the Motorola HEP line of replacement transistors. Germanium and Silicon. Pages 10, 11, 12.
From FB group Building Transistor Radios, 2018-09-02 I already see one mistake. On p.27, Audio Mixer. The R6 is only 1k. The voltage divider R5 and R6 will give a voltage less than 0.6 at Q1’s base, which means Q1 will not be forward biased enough and the circuit won’t work or else sound distorted.

Ever since I’ve been experimenting with Joule Thiefs I’ve done so with the intention of using the circuit for boosting a low voltage source to power a higher voltage circuit. So I think this Analog Devices ADP5090 is very useful for doing just that: powering circuits up to 200 mW from very low voltage power

I tried posting this on Facebutt, but it thinks this single image .GIF is a movie! So I’m putting it where all can get it.
