That is an incredibly bizarre point of view lol.

I could waste a lot of time, but I will just zoom right to the end - one day humans will be completely divorced from nature, and we will be sustained just by technology.

You really think things like Amazon deliveries (powered by amazing logistics not possible without computerization) did not have a profound impact on society?

That's probably because as soon as it becomes practical its suddenly no longer AI. Look at the very wide and successful implementation of things like voice recognition, photo and video manipulation filters, machine translation and more.

When image generation ends up in Adobe it will be immediately forgotten as an AI landmark and just be used by professionals to improve their productivity.

So the average American install is 20-25 panels, and the average cost for a new 300w panel is say $200, which means the main hardware cost is around $4000-5000. Add another $1000 for an inverter.

Yet we keep hearing a typical install is $50,000 and the pay-off period 20-30 years because of that.

It sounds to me like the main issue is labour costs, which is why I think self-install or low-skill install should become a thing.

You can already buy plug and play kits, and you can now get adhesive mounting kits which means there is no risk of leaks and no roof penetration.

It seems no matter how cheap the panels become, the cost of install which seems to be nearly 10x more than the hardware, is going to hold solar back.

If the cost of labour can be reduced by a lot in USA solar would immediately become a lot more viable and attractive.

Recharging times compared to petrol cars have been one of the biggest objections to EVs, but advances in car fast chargers have made this less and less of an issue.

Nio has just announced a 500 kW ultra-fast charger called Power Charger 3.0 on Nio day. It has a maximum charging current of 660A and can charge EVs based on 800V architecture from 10% to 80% in 12 minutes.

These advances, which should become ubiquitous amongst EVs over the next few years, will mean we need fewer superchargers for long-distance travel, and that EVs will become even more practical for those without chargers at their homes.

Because the system is poorly optimised for this. Imagine a system using adhesives saving $30,000. That sounds like a lot of motivation.

> For years, Fraunhofer CSE has been working with the U.S. Department of Energy, through its SunShot initiative, and other stakeholders on approaches to lowering the cost of installing solar PV, including a “Plug and Play PV” approach designed to reduce the installed cost of solar to $1.50 per kilowatt by 2020, about half of today’s average price. To meet this objective, Fraunhofer CSE and its partners have worked to develop an adhesive-based mounting system that eliminates the need for drilling holes through the roof structure and for electrical grounding, which can save installers several hours of work per site.
