CGA to VGA Converters

Use a CGA to VGA Converter to view an old PC on a more modern display:

Intel CPUs - Core i3, i5, i7 or i9?

For a NAS server, a Core i3 is probably more than adequate.  At the other end of the scale, Core i9 has more capability than needed (or used) for a home desktop PC.

Which Intel Core CPU is the best? How do I decide between a Core i3, i5, i7 or i9?


ThermoBlock™ insulated concrete forms (ICF)

ThermoBlock™ insulated concrete forms (ICF) utilize post and beam type construction (rebar in concrete):

Check local building codes.  Cost could be 10% more than conventional construction, but the improved insulation is worth it.

A Shockingly Quick, Wind Tunnel-Tested RV

The C2 Corvette Designer Created A Shockingly Quick, Wind Tunnel-Tested RV That Used Its Exhaust System To Incinerate Your Poop:

"Depending on who you ask, just 3,300 Rectrans Discoverer 25s were ever put on the road before the company fizzled out around 1974."


The 1970s RV Technology That Cooked Your Poop As You Drove:

"The adjacent bathroom is equipped with a Thermasan waste destruction system that was designed to dispose of liquid and organic waste materials through the exhaust system."

"In this system, wastes would go straight from a toilet and into a grinding machine or macerating machine. Once the waste is ground into small particles, they would go into a holding tank. The waste would then flow into a heating chamber, where the waste would be disinfected through a heating process. Once the waste particles are heated to 170 degrees and once the vehicle reaches a determined speed, a valve opens, disposing the apparently disinfected waste onto the ground."

'Thermasan will only destroy wastes when the engine is hot enough and when the vehicle is traveling at a high enough speed. When the engine is hot enough and when you're going at least 30 mph, the system can activate. "
"... the waste is injected into the exhaust flow at its hottest point, which Thetford says in the brochure should burn the waste up so well that there are no visible discharges from the exhaust or a smell."  (Even more efficient with catalytic converters?)

Now, mostly replaces by Macerator Pumps and dump tanks:  https://rvlifestyle.com/rv-macerator-pump/
