Power Through A Hurricane

When living in an area that is prone to natural disasters, it’s helpful to keep something on hand for backup power. While a large number of people chose to use generators, they are often unreliable (or poorly maintained), noisy, produce dangerous carbon monoxide, or run on a fuel supply that might not be available indefinitely. For truly reliable backup power, [Jay] has turned to a battery bank to ride through multi-day power outages.

While the setup doesn’t run his whole house, it isn’t intended to. One of the most critical things to power is the refrigerator, so this build focuses on keeping all of his food properly stored through the power outage. During the days following Hurricane Irma, the system could run the refrigerator for 10-11 hours, and the thermal insulation could keep everything cold or frozen overnight. Rather than using solar panels to charge the batteries, the system instead gets energy from the massive battery of his electric vehicle. [Jay] was out of power for 64 hours, and this system worked for him (and at a better cost) than a generator would have.

With the impact of major storms on many areas this year, we’ve been seeing a lot of interesting ways that people deal with living in areas impacted by these disasters. Besides riding through power outages, we’ve also seen the AARL step in to help, and also taken a look at how robust building codes in these areas help mitigate property damage in the first place.

 

Parts Bin Emergency Lights Deal With Tornado’s Aftermath

Sometimes having a deep inventory of parts in your shop is a pain – the clutter, the dust, the things you can’t rationally justify keeping but still can’t bear to part with. But sometimes the parts bin delivers and lets you cobble together some emergency lighting when a tornado knocks out your power.

It has been hard to avoid discussions of the weird weather in the US this winter. The eastern half of the country has had record warm temperatures, the west has been lashed by storms, and now December tornadoes have ripped through Texas and other parts of the south, with terrible loss of life and wide-ranging property damage. [TheTimmy] was close enough to one massive EF4 tornado to lose power on Saturday night, and after the charm of a candlelight Christmas evening wore off, he headed to the shop. He had a bunch of sealed lead acid batteries from old UPSs and a tangle of 12V LED modules, and with the help of some elastic bands and jumper clips he wired up a bunch of lights for around the house. Safer than candles by a long shot, and more omnidirectional than flashlights to boot.

The power came back before the batteries ran out of juice, so we don’t get to see any hacks for recharging batteries in a grid-down scenario. Still, it’s good to see how a deep parts bin and good mindset can make a positive impact on an uncomfortable situation. We’ve seen similar hacks before, like this hacked cordless tool battery pack or powering a TV with 18650 batteries. Be sure to share your story of epic power-outage hacks in the comments below.
