I was reading Superfreakonomics when ...

The authors claim that the shoe bomber failed to ignite his shoe bomb and kill anybody, yet security measures brought in to prevent future shoe bombings cost airline passengers to lose 1065 years , or the entire lives of 14 people.

How to make use of this time ? Combine distributed crowd-sourced commodity computing (Iexec white-paper)  and the design for body-movement-phone charger, and people standing in the queue can be working out charging their phones, all the while renting out the computation power of the phones to the 'net, so that they get paid and their insurance premium comes down too.
Two birds with one stone. Aw yeah !

The Shib would probably get providers from  Aliexpress ...

There's a fun list of ideas here -

The one that triggers my delight is the one which uses heat from a boiling pan to create electricity to charge your phone. This has been an ongoing thing with me - best improvements seem to come from harnessing li. Very Tao.  Most of human progress involves using processes and tools that require not thinking. And hence these frequently go against the li of nature.
The fabulous Prius uses the moving car's need to lose energy fast to charge the battery . All that energy was going waste all these days. Wham ! impressive mileage and a higher value car with phenomenal gas savings when driving within the city.
Similarly , here's a list of things I 'brainstormed', after watching a bicycle driven washing machine ..

These are ,in order -
a) A hydraulic charger leveraging people's & car's needs to descend from
b) a potential energy battery , and cranks connected to, say, gyms and escalators
c) a small body charger consisting of a wind up spring and a bull worker
d) desert cooler (adiabatic expansion wala)
e) sloping streets friendly to skateboards and scooters
and some old goldies
f) fresnel heater and steamer, fresnel net roofing
g) solar still desalinator pipes

I will go in more detail in these soon.

The Singularity will take us to Mars and beyond. It will create nano-machines that will crawl our bloodstream and handle Defense & Repairs.  It will create matter compilers , molecular transmuters and 3d printers so that we can feed any old material and create anything from modern day manufactured items to food, to biological tissue and organs . It will be, as Gibson says, the end of economics.
Until then, we must work as midwives, easing its entry into the world.

JP thinks that the world population is around 7 billion , and it would peak at around 9 billion and then fall rapidly. Until then, there is going to be a tremendous demand on ,of course, food & water, shelter & sanitation, transportation, medical &  health services, and then on learning, training & education.
Existing systems, businesses and institutions will have to learn to handle scale growth in their users.

According to YNHarari we have the means to create enough food and water for all the world to eat. All scarcity today is due to existing political structures & incumbents which do not permit upgrading of facilities for fear of loss of power.

There are open source village construction kits which can be leveraged to setup communities in wastelands ( not cleared forests please).

There is enough free and high quality video and text content on the internet for volunteers to bring people to the fold of beyond-high-school mathematics.

Still, ideology and irrationality are the largest drivers of human awareness. McLuhan famously said "I'll see it when I believe it", and so while the Singularity, and Plenty are knocking furiously on our doors, the masses can only see the world from the scarcity of previous failed movements like communism and casteism. More rational models ,like we can do more with less thanks to brains and science,  have not yet spread enough , however the mind of man can quickly assimilate any idea that is in his favor.
