Thomas Edison in 1910. But let’s not get ahead of ourselves on this net zero business, lads
Someday some fellow will invent a way of concentrating and storing sunshine to use instead of this old, absurd Prometheus scheme of fire.
I'll do the trick myself if someone doesn't get at it....
This scheme of combustion in order to get power makes me sick to think of—it is so wasteful.... We should utilize natural forces and thus get all of our power. Sunshine is a form of energy, and the winds and the tides are manifestations of energy. Do we use them? Oh no; we burn up wood and coal, as renters burn up the front fence for fuel.
We live like squatters, not as if we owned the property. There must surely come a time when heat and power will be stored in unlimited quantities in every community, all gathered by natural forces. Electricity ought to be as cheap as oxygen, for it cannot be destroyed.
Now, I am not sure but that my new storage battery is the thing. 167

The upshot is that the party that most hates the first past the post electoral system is using it most effectively. The LDs have experience in 2019 of racking up votes with a divisive message and getting very few seats. Some LDs think the Greens and Reform are making the same mistake.

They disinvented the VCR. You might think that the reason we don't have VCRs anymore is because VCRs were supplanted by DVDs, PVRs and streaming, but that's not the case. They had it in for the VCR from the very start, and they never stopped trying to kill it. Eventually, they succeeded. 1/
A 1960s family living room in which a mom, dad and two kids are mesmerized by a cabinet-style TV. The image has been altered. The TV has an early 1990s VCR atop it. The TV screen is displaying a cross-sectioned human head with brains and spine on display. A huge fist has materialized in the room, with bloody spiked knuckle-dusters, smashing into the VCR. The oil painting over the sofa has been replaced with a pulp image of a male head, its cranium removed and replaced by a dome. Inside the dome is a red eight-segment VCR clock, displaying 12:00. The background in the painting is a tangle of cassette tape. The whole image's colors have been boosted, giving it an overexposed look.
