Lifetime Energy

They are developing a battery that uses radioactivity to provide years of automatic recharging. Carbon-14 contained in irradiated graphite is press into diamonds, then surrounded by another layer of non-radioactive diamond. The beta decay generates a charge that is captured by the surrounding solid-state structure and passed on to an external circuit. Essentially it's a self-charging battery with a power density higher than today's lithium ion batteries. You could have an i-Phone that could fully recharge itself from zero to full charge 5 times an hour. The battery is practically indestructible and could be scaled up for automobiles.

Dark Clouds

Free speech dies in China. With this step, free speech in Hong Kong becomes extinct. The free world now faces a truly monolithic adversary where the last bastion of human rights has now been razed. What will be our response? Our global economy has become dependent on the products from China. The very size of her population and technological prowess casts a shadow over Asia. It's probably past time to think about ways the free world can protect the Chinese from their own government as well as our own economic future going forward. Especially when the U.S. government is so stunningly incompetent under the current administration.
