Yep, after decades of false starts, it is now possible – for the few, the young and the obsessive – to make  a living playing video games. Sprung from LAN party tournaments played for beer money stakes, eSports has today evolved into full-blown sporting franchise, complete with teams, groupies, college athletic programs, dedicated media, arena-filling crowds and tournament prize pools ballooning into the tens of millions of dollars.

For many, this development raises a number of questions. Are these really athletes? (Hint: the U.S. government thinks so.) Why was Amazon willing to pay almost a billion dollars for Twitch.tv? And, well, just how does professional gaming work?

Time-Warp: The Unfolding Story of 4-D Printing

It’s probably something like this.

4-D printing remains in its early stages, It’s certainly too early to tell if  it’s anything more than a buzzword, let alone if its promise will translate into practicality. But the sorts of people who bet on these kinds of things are betting on it.

And why not? Suppose a structure could unfold itself, like origami. Imagine if walls could flex or stiffen in response to shifting loads, or if a buried pipe could change shape to accommodate varying water flows — or to pump water via peristalsis, like your digestive system. Through 4-D printing, nothing is set in stone unless you want it to be.

Eureka! I Have Lost It!

Left to our own devices and allowed to live without constant fear of death by hunger or violence, we devise some pretty startling stuff.

Sure, some of our better efforts don’t outlast our calamities, or go obsolete before their time or simply never get their chance to shine because no one yet recognizes the need for them. But you can’t keep a good idea down forever, as I explore in this list of …

The latest NASA space probes to make the news have zoomed to the farthest reaches of the solar system, and their names – Pluto’s New Horizons, comet 67P/Churyumov-Gerasimenko’s Rosetta and Philae – reflect the ambition and spirit of discovery behind them.

But who gets to pick those evocative names, and is there any pattern that ties them together? Read on …

Tesla’s Powerwall: Reading the Meter

April 2015 saw Tesla Motors’ entry into the home and industrial battery market. Thousands of pre-orders – and more than a little hype – attended the announcement, and it’s easy to see why: The promise of a cost-effective home battery, one that could make self-storage an equal or better option for solar customers than the prevailing sell-and-buyback model, could revolutionize the solar industry.

Yet some experts argue that the battery is not all it’s cracked up to be, while harsher critics accuse Tesla of using the storage cells as big green stalking horses, part of a plan to bilk taxpayers into subsidizing the company’s massive battery factory and R&D facility in Nevada. Read on as I make the connections in …
