To be clear, I know what it is. In fact, I'm probably one of the few in the site who could guesstimate how much energy it is without looking it up (covalent reactions, per mole are equally energetic to within a fairly narrow margin; thats why, hydrocarbons are more less equally energetic)

But it's meaningless, unless you're a demolitions engineer. What's the volume of a ton of TNT? I guess - within a factor of two - about the same as a ton of water? So a cubic meter? Who knows?

If it's near IR, bright and erratic, enough will get through and it will mess up with the auto gain.

Start up idea:

Ordinary glass (as in spectacles) frames that have a near IR LED on the bridge and on the side. PWM to be efficient, bright, but erratic clock of around 10Hz.

"230 tons of TNT"

I hate units of TNT. Ill do psi. Love the foot. The calorie is metric! But what on planet earth is "ton of TNT"?

The energy that was dissipated (using 0.5 mv^2) was 1TJ, or the 280 000 kWh.

The HP28s is amazing. The manual even has a program to convert an algebraic expression to rpn.

In high school it was mind blowing.

But I didn't do anything serious with programming. Normal languages seemed annoying, usr/rpl useless limited as it was to a 4 bit calculator.

Maybe if someone had told me usr/rpl is just lisp. But, it's for the best. I loath computer screens today.

The avro was an excellent plane for the time. It would have been a good plane for the Cold War. It was a plane well suited for Canada's threat environment. The missiles that replaced it sucked.

However, the Avro wasn't anything any of the other great powers couldn't do back then or today and it was ruining Canada financially.

The only question I have about the Avro is: "Could foreign sales have rescued the plans and Ottawa's budget?"

I think not. In an era of hyper-protectionism where the Brits built an air cooled nuclear reactor [1] rather than buy Canadian heavy water, it's inconceivable that Canada would have found buyers.

[1] resulting in the largest nuclear disaster until Chernobyl. Keep in mind, at the time, English Canada largely thought of itself as British and even decades later fumed at the new flag lacking the Union Jack. And yet the Brit's didn't but their heavy water.

Folks in the South don't consciously realize it, but they're setting the AC low to keep it running for its dehumidification.

These are the same folks who sweaters is its 80F outside. They can handle heat.

If ACs had the ability to run as dehumidifiers in convinced the temp would rise
