Blogger Ron Brinkmann doesn’t want to buy an overpriced laptop stand or build his own DIY laptop stand. Instead, he takes the cheap and easy route and uses a $6 hot water bottle as a water-cooled laptop stand. Brinkmann says:
Yup, buy a hot water bottle, fill it up with tap-water (room-temperature is fine) and insert strategically between laptop and lap. It’s comfy, acts as a nice heat-sink, and as a bonus it probably blocks a fair bit of the dangerous ‘electronic rays’ that are shooting out of the bottom of the computer straight at your important bits.
Brinkmann claims the water bottle works great on the table as well—just lean your laptop on the water bottle and the rubber surface grips the table and keeps your propped up laptop in place. Nothing beats this cheap and simple, and the cooling effect of the water bottle means no more burning laps.
