Episode notes
ENIAC's Hot Tubes Challenge
- The ENIAC computer's vacuum tubes ran extremely hot, requiring air conditioning and powerful blowers for cooling.
- Its tubes often burned out due to tight packaging and poor air circulation, illustrating early cooling challenges.
Transistor Heat Reality Check
- The transistor was initially believed to emit no heat, promising heat-free computers.
- This hope was naive as dense transistor packing created significant heat needing new cooling solutions.
Liquid Cooling Advantages
- Liquids absorb and transfer heat far better than air, making them ideal for cooling electronics.
- Water is best for heat transfer but corrosive, leading to research into alternative cooling liquids.
