> Nobody thought cars would be bad for the environment when they were inventing them

You’re telling me nobody coughed like mad drone inhaling the exhaust fumes (or died) early in car development?

Nobody dumped their used engine oil on the ground to kill plants and bugs on purpose?

Of course they knew.

Why do you assume that? Just because we’re doing it on a colossal scale doesn’t mean it has to be that way.

And, traditionally, in California, the location in TFA, has this solar thing worked, or not worked?

In virtually all regions.

I’m in Canada in a tight valley with tons of snow. The 7.2kw on my roof will profit me $25k-$30k over their life.

It works very well, even here

Solar plus battery and some wind now beats everything else by such a wide margin it boggles my mind we’re even still talking about, or contemplating anything else.

By the time you finish reading this, solar panels got cheaper

If gas prices in the US were like the rest of the world, only rich people could afford to drive a car with a 400 cubic inch engine.

I put 7.2kw on my roof in Canada. Tight valley, tons of snow.

You know what I learned about all the projections and estimates?

It’s a complete waste of time . Panels are so cheap now just slap up as many as will physically fit and get on with it. Everything else is a waste of time.

Over their 25+ year lifespan I’ll profit $25k-$30k.

It’s the no brainer of all time.

As soon as my garage build is done I’ll cover that roof in another 8kw of panels too.

> they're not chatting with their secret BFF

If a person told their real BFF they were planning a shooting and went through with it, couldn’t the BFF be charged with accessory?

400 cubic inches for 401 horsepower each. Pushrods, two valves a cylinder.

This is nothing to celebrate.

I had no idea there were PUA companies. Huh.

I was into the PUA thing, and I disagree the comment above is that.

The PUA scene was about gamifying or exploiting dating - hacking how you go about it for your own gains (getting laid)

Approaching women in public with good intentions and to feel more comfortable talking to women is not PUA. It’s one of the suggested things to do, but I think intentions matter a lot.

I was flabbergasted scrolling Tinder on a female friend’s phone.

90% of the guys had a photo of them with their pickup truck, a pic of them drinking heavily, and a pic of them giving the middle finger.

Not in a particularly redneck or rural area either. Lowest effort possible.

Are you suggesting we should stop using water to grow food for humans?

For fun, Gemini says between 1.1 and 3.8 billion, and 3-5 years.

That number will decrease every month too.

Place your bets now.

Time until first power generated, and actual final total cost.

I’ll go 15 years and $10 Billion.

Immensely. Especially early in my career I felt very different to the comp sci grads around me. I was trained to think at a systems level, about consequences, about people and processes. In the first few months it was obvious to everyone I was a leader and quickly had a team.

Somehow I felt like I was thinking about the big Picture and the ramifications for the future, those around me were just looking at a tiny problem.

It also helped immensely for talking with the Engineers at various companies.

My education was like an electrical engineer is to an electrician.

My degree is Software Engineering, and is fully accredited by the Australian Institute of Engineers.

It was two years longer than computer science, and all of those extra courses were with the “mainstream” Engineers.
