I have an air source heat pump for my house and a heat pump water heater. Even in the dead of winter at 0F it kept my house just as warm as always and my water was hot. Heat pumps are not "shitty alternatives" any longer. Maybe in Alaska they would struggle but anywhere else and they work just fine.
If we want to honestly improve the climate then it is REQUIRED that we become carbon negative, not just net zero. And every little bit of emission that is prevented is a lot of power that isn't needed later on to suck that carbon back out of the air.
You can complain that big companies aren't doing enough to cut emissions and I agree, but that doesn't mean we should wait till they clean up their act to start working on ours.
Yep, the standards for energy efficiency in homes is just barely above being non-existent. We spent decades with cheap energy so no one cared if every house leaked like a sieve. Now that's coming back to bite us.
I have a cyber truck and it's amazing the disconnect between online and real life. This thread is evidence that online everyone hates it and thinks it's the worst thing ever. In person I can't go anywhere without someone wanting to ask me about it and gushing about how cool it is. Seriously, I constantly get thumbs up and smiles and "woah that's so cool who made it?" The sentry mode has seen many children pose in front of it while their parents take a picture.
The attention aside it is genuinely a good truck. 6ft bed, 120v and 240v outlets in the bed for power anywhere, 11000lbs towing capacity, 6000lbs bed capacity, 300 mile range, the battery storage to power my house for a month if I don't use A/C, a week with A/C, super fun and smooth driving, tight turn radius from the rear wheel steering, room for 5. If it looked like a normal truck but everything else was the same noone would care one way or the other.
My girlfriend follows the Facebook group for our local area and has shown me many posts from people seeing one and posting about how cool it is. And I've gotten only one negative reaction from someone giving me a thumbs down as they drove the other way. Haters have had plenty of opportunity to give me the bird or thumbs down but it just doesn't happen.
I got my cybertruck because I wanted to do truck things on electric power. The attention never factored into the buying decision and once deliveries started rolling out I was nervous about the attention it was drawing for other people. Luckily all that attention has been positive for me.
The idea of the Dyson sphere, or actually Dyson swarm as it was originally proposed, assumes that there is no weird new physics that makes energy for free. If you have truly free energy then all bets are off for what you can do with it. If there are no new thermodynamics breaking discoveries then even with cheap fusion reactors making a Dyson swarm is the best long term way to get huge amounts of energy. With decent automation only a little better than we have now and a few centuries of time you could disassemble Mercury into space habitats with room for easily quadrillions of people. So without magic free energy why not do that?
Climate goals could make gas heating obsolete. So why do gas companies keep adding customers? Building more gas infrastructure is like investing in video rental stores 15 years ago, says expert ( www.cbc.ca )
