Given what happened before you really can't fault him.

How much would he have gotten in royalties anyway? I don't think there are any billionaires who got there just through patent royalties, right?

The inventor of the B&D Workmate has earned a 3% royalty on 55 million sales. That's almost certainly over $100m. It's very rare to make a lot of money on a patent, but for something popular let alone ubiquitous it's entirely possible.

Kind of off-topic, and I'm sure I'm not the only one thinking this, but is it common to have clarity of mind at age 92? Is it mostly genetic or is it more like "keep challenging your mind and get enough sleep"? Anyone have good links? At 29, I'm (probably prematurely) worried about cognitive decline. I only started challenging really myself last year.

CPU speeds stopped increasing because the market stopped focusing on CPU speed (coincidentally to this discussion, the change was largely to reduce power demands). Transistor count has kept plugging right along; http://i.imgur.com/FvVrnn4.png

I think it's the other way? That is, market stopped focusing on CPU speed because they hit the wall and clock speed could no longer be used as a differentiating factor.

Yes, market would be more than happy to have 100GHz CPUs by now, it would make scaling everything much easier.

> But Goodenough is equally dismissive of such tinkering and its measly 7% or 8% a year in added efficiency. 7% extra efficiency per year means electric cars will have twice the capacity in 10 years...and then double up again in 10 more years...and so on. That's a far greater rate of improvement than for gasoline-powered cars, even if we're impatient and we want our $10,000 500 mile on a charge EVs now . > But the pa…

Having done a little science myself, usually there both are small incremental improvements with small but predictable gains and large leaps with big potential gains but very unpredictable outcomes. The former are optimizations around a current local optimum, and the latter try to escape it towards a better local optimum. For that reason the incremental gains tend to saturate over time, and I suspect that is what Goodenough is dismissing.

What I'm worried about is the waste of lithium and other battery/accumulator metals. In theory, people should turn electronic devices and batteries to recycling facilities, but a large part of the population ignores the rules and throws their gadgets into the trash when broken... I wonder if someday we will find a way to "separate" trash on atomar level (i.e. put arbitrary stuff in on one side, get raw atoms on the o…

It is a big issue, but these facilities are becoming more common. One trick that works for me: put used batteries inside an empty bottle when the bottle is full take that to the facility.

> Without it, we would not have smartphones, tablets or laptops, including the device you are reading at this very moment. Yes we would. All these things existed without Li-ion. The power/space budget would be more constrained but it was perfectly achievable. What wouldn't work is senselessly burning cycles running managed code in a VM with heaps of battery sucking DRAM. People today have no concept of how much compu…

If it was possible to use a lot less power by programming that way without any other tradeoffs there would probably be a market for a device with a much longer battery life.

I think one thing you can do is try to avoid a typical fallacy. My brother gave me a great example:

- When people get older (say around 30-40), they realize that they can no longer memorize stuff quite as good as in their twenties

- They start to write notes a lot more in order to make sure they don't forget stuff

- Now they get even worse at memorizing stuff, because they challenge their memory a lot less

Where I live, at least, I'd have to make a special trip between 9-5 on a weekday to a battery recycling facility. And when I'm free on a weekday I'm not spending that time schlepping batteries across town. If they included batteries in curbside recycling pickup, you'd get the same high rates you do with paper, plastic, glass, and metal.
