Funny enough, it was someone's side project at Google.
So was Maps, originally. This is why there's so many fans of the 20% project concept.
GMail however is a 20% project. :)

Also, don't discount the rising level of violent conflicts that will ensue for shrinking resources.
Conflicts don't cause extinction. The winner survives.
As an analogy, think about what happens if a deadly infectious bacteria or virus "wins" by infecting every human on earth. If there is no cure and no human has an adaptation or mutation to stop it, by winning it has sowed the seeds of its own destruction because there are no more hosts to infect.
It is easy to imagine several scenarios where an all out war for dwindling resources can lead to extinction.
I have always been a huge fan of a quick transition to sustainable energy sources. There is just one little thing I don't understand. Why they expect people to make electricity at their homes? You can buy a little piece of land in a dessert, put solar panels there and distribute the electricity to other places. And you don't have to climb on any roof during the installation or the maintenance. It is not profitable to…
A local power company in my town does this (New Zealand) You buy a 'solar panel' and they add it to their solar farm while giving you the equivalent discount. The best thing is that if you move house the discount follows you.

A distributed file sharing system (later known as the Internet) was Tim Behrners Lee's side project at CERN for a while too :) He was only allowed to take his 20% project to 100% after his manager wrote up a justification XD
> later known as the Internet My turn to be pedantic, I guess, but 80 and 443 are only two of many available ports. The internet is much bigger than just the web, even if lots of people never bother to look beyond their browser.

roofs != houses
Houses need roofs that last. Why put a new roof on every 15-20 years if you can put one on that lasts the lifetime of the house?
Please don't seriously suggest Tesla's solar roof will last the lifetime of a house to people.
The real warranty is 30 years for power and weatherization.
Its misleading marketing speak (at best).

> Weatherization means that there will be no water leaks or other weather intrusions during the 30 year warranty period that result from our installation.
It will almost certainly require replacing and/or serious repair long before the "lifetime of the house" is up.

> Tesla's calculator estimates $40,500 for a roof that generates half our power needs, and should provide $20,400 worth of energy over 30-years. This depends quite strongly on where you are. Your numbers are very close to the ones I get if I use my correct address, which is in the Puget Sound area of Washington State. If I keep everything the same except the address, changing that to one in Merced, California, then i…
Seems off. Seattle gets 1/3rd the sunlight of California.

$35k for a car is absolutely mainstream - in fact that's just about the average price for one... [1] https://www.usatoday.com/story/money/cars/2015/05/04/new-car...
That's the average for a new car. Most people don't buy new cars.
Does anyone understand how the warranty works? From their solar panel page[0], it says that there is a 30 year warranty for Power and Weatherization and a lifetime warranty. So, what does the lifetime cover? The only thing that can go wrong is that either the power module fails or the tile is damaged due to weather, which is both covered by the 30 year warranty. Nevertheless, a 30 year warranty is still pretty impres…
> Nevertheless, a 30 year warranty is still pretty impressive and even more so if it covers normal wear and tear from weather. If Tesla is around in 30 years. Remember that Tesla was going to go bankrupt 9 years ago before government bailout. And warranties can become worthless when companies go bankrupt.

It's the right question to ask. Home electricity costs around $0.15/kWh, while power plants sell electricity to the grid for around $0.03/kWh. The difference pays for installing and maintaining the grid and local distribution wires to your home. Depending where you are (I live in a forest, where a tree falls on the power lines a few times a year and they have to send out guys in a bucket truck to fix it) it's expensi…
Wth is wrong with the USA? It seems like you're getting screwed over everything. 10x electricity, 100x healthcare and education - is US market really just a bunch of colluding monopolies?
