Re: Coronavirus pandemic

I am astonished how cavalier many people are about this virus. Even with a mask and gloves, the risk is non zero. Groceries, gasoline pumps, door handles, mail, passing cars, and on an on. No place is immune. Numbers are starting to take off now. Much faster than in March. Death rates will also clim...

Re: HEAS 2020 the 31st year ????

Richard, I have to be honest but the odds of me attending is probably only 10%. I have totally enjoyed attending most of the last 20 years. This year however is somewhat problematic with the COVID bug. At time of writing, only 10% or less of the population has been infected. It has been 6 months so ...

Re: Fusor V construction - the process long running

Short, straight line vacuum lines are notorious for carrying HV plasma to critical components. Early on, two of my thermocouple gauge tubes were fried due to HV making it to them. Everything was well grounded but it still took them out. Now I have a series of bends and some distance between the cham...

Re: Space X conversation Xfer

I am with you Richard. No touch screens for me. Sometimes if my hands are too wet or dry, they don't even work on my phone screen. Sometimes you miss by a mm and get the wrong action. With all of the vibration on takeoff, try to hit the correct moving abort dot on the screen. Even without the radiat...

Re: Coronavirus pandemic

It is not a mathematic calculation as much as it is a PR campaign to energize the youth of the world. NASA had become stale and had lost funding. Bring in the "awe" factor and you have a thirsty young world out there looking just for this. Look at the energy around these launches. It was like us old...

Re: Coronavirus pandemic

The way history has been being dismantled, there may not even be a mention of us or we will be labeled some derogatory generation. I say this not to start an argument about social changes seem to be going in the wrong direction. What amounts to book burning and rewriting history seems to be what man...

Re: Farnsworth Questions

I understand all of what you present Richard. The relative fast increases in cross section really start to level out above 110 kev. From this alone, there is no reason to go higher. There is however, another factor that needs to be considered. That is the area under the curve. It is not just a 1:1 f...

Re: Farnsworth Questions

Nickolas, For some reason this thread fell under my radar. As it turns out, the design I thought was Einzel lens were not. They were to confine or recycle in electrons. I also looked more closely at the drawings that were posted here in one of the threads and that indeed is what was trying to be don...

Re: Coronavirus pandemic

Even we technical people cannot are on facts. How can we expect the general public? If we believe that there is global warming and man is responsible, are we willing to go back to a carbon footprint of the early part of the 20th century? That is when the industrial revolution CO2 producing candle wa...

Re: Coronavirus pandemic

The point about "alternative" energy technologies is that they are a little like the current state of nuclear fusion. You put a bunch of energy in and you may or may not get that much more out. We spend too much time debating if it is a net winner or loser. The difference is not a factor of 10 or 10...
