DIY Powerwall Builders Are Using Recycled Laptop Batteries to Power Their Homes
One of the really disappointing things about Tesla is how incredibly proprietary all of their products are. For a company that has such lofty goals as &quot;saving the world&quot;, it feels wrong to me for them to then sell DRM cars and unrepairable black boxes. Maybe I&#x27;m just too idealistic, but surely if we have an opportunity to create a new market for solar devices why would we decide to recreate the proprietary world of the 1980s? Creating your own powerwall from recycled batteries is a pretty neat hack, and I&#x27;d hope that people are publishing free (as in freedom) hardware designs for said battery banks.
