In the midst of the global pandemic, a group of anarchists from Portland has MacGyvered a DIY heater that costs $7 to make.
Last winter, Seattle saw 221 unhoused people die from hypothermia. This year, concerns have increased with the arrival of Omicron. To help homeless communities stay warm during the cold winter, anonymous members of Heater Bloc designed the Copper Coil Alcohol Heater. The design uses affordable and easily accessible materials. Instead of propane, it uses isopropyl alcohol as fuel, which is cheaper, reduces the risk of carbon monoxide poisoning, and can be safely used in tents.
