The periodic table limits battery breakthroughs, with only 118 elements, most unsuitable: - 39 are radioactive - 23 are too scarce or costly (e.g., rare earths, platinum group metals) - 6 are inert noble gases - 4+ are toxic (e.g., cadmium, cobalt, mercury, arsenic) - Some are too heavy, scarce, valuable (e.g., gold, platinum), hard to recycle, or have low reduction/oxidation potential Energy density has peaked by using lighter elements—from lead to zinc to nickel to lithium. Be skeptical of battery improvement claims. A 100% renewable grid needs at least six weeks of energy storage. Storing one day of U.S. electricity with Li-ion batteries would cost $11.9 trillion, cover 345 square miles, and weigh 74 million tons, excluding grid upgrade costs. The mining required is immense and must be repeated every 15 years. Other battery types exist, but commercial focus remains on lithium. A 100% renewable grid with battery backup is a pipe dream.
Not ECDSA. Not Schnorr. Meet DahLIAS 🌺
A full aggregate signature scheme, that actually works on Bitcoin’s curve!

We have just released vminer: a virtual machine introspection tool. Unlike icebox our previous project, it is not tied to any specific hypervisor, and can also run on memory images! Built with ♥️and 🦀 https://t.co/8Z2d65x1WI
