…Redwood believes that by 2030, end-of-life batteries could supply more than 50 percent of the entire energy storage market. Instead of grinding up used batteries to reclaim the critical materials inside, put them to work storing electricity. There have been many experiments done that re-purpose used EV batteries which no longer can supply enough power to meet the need for rapid acceleration in an EV but still have up to 80 percent of their original energy storage capacity available…

…Traditional energy storage systems are high density and require heavy-duty cooling. To avoid this, Redwood’s team opted for an open-air, low-density system mounted on above-ground cable trays.

Spreading packs out in the open air helps avoid the need for active refrigeration, and stripping away moving parts like fans and filters minimizes potential reliability failures. Keeping the wiring above ground and limiting the size of each modular component minimizes the need for large equipment. As Sun explained, the result is a storage system that is faster to build, easier to inspect after storms, and cheaper to keep running over time…

…because VPNs obscure a user’s true location, and because intelligence agencies presume that communications of unknown origin are foreign, Americans may be inadvertently waiving the privacy protections they’re entitled to under the law…

…VPNs might protect you against garden-variety criminals, but the intentional commingling of origin/destination points by VPNs could turn purely domestic communications into “foreign” communications the NSA can legally intercept (and the FBI, somewhat less-legally can dip into at will)…

Certainly the NSA isn’t concerned about “incidental collection.” It’s never been too concerned about its consistent “incidental” collection of US persons’ communications and data in the past and this isn’t going to budge the needle, especially since it means the NSA would have to do more work to filter out domestic communications and the FBI would be less than thrilled with any efforts made to deny it access to communications it doesn’t have the legal right to obtain on its own.

Since the government won’t do this, it’s up to the general public, starting with everyone sharing the contents of this letter with others. VPNs can still offer considerable security benefits. But everyone needs to know that domestic surveillance is one of the possible side effects of utilizing this tech.
