New spongelike material converts solar energy into steam

solar sponge

The DLS that consists of a carbon foam supporting an exfoliated graphite layer.

MIT has developed a new material structure that generates steam by soaking up the sun. The structure — a layer of graphite flakes and an underlying carbon foam — is a porous, insulating material structure that floats on water. When sunlight hits the structure’s surface, it creates a hotspot in the graphite, drawing water up through the material’s pores, where it evaporates as steam. The brighter the light, the more steam is generated.

Generating electricity from jumping water droplets

water droplets

This process can generate small amounts of electricity.

Last year, MIT researchers discovered that when water droplets spontaneously jump away from superhydrophobic (water-repelling) surfaces during condensation, the droplets can gain electric charge in the process.

A ‘bioconcrete’ house that turns rain into drinking water

Rain House

This concrete house turns into an oversized water filter every time it rains. Rainwater runs from the roof through a custom-designed system and ends up in a cistern, clean enough to drink. A demonstration building was on display during Milan Design Week last month, complete with a fake cloud overhead to show it in action. (Photos)

Discovery of water-containing gem points to vast oceans beneath the Earth

Diamond sample containing the hydrous ringwoodite.

The Earth’s transition zone is the part of the Earth that exists between the upper and lower mantle. Scientists often theorize what lies in the transition zone. Many believe that the transition zone contains a lot of water, but there was no proof to support that idea. A group of geologists from the University of Alberta uncovered a water-containing gem that finally confirms this theory: there is water, possibly massive oceans of it, deep beneath the Earth’s surface.

Graphene oxide could offer a solution to unlocking our most abundant water source

Dr Rahul Nair demonstrates a graphene-based membrane device.

Many of us struggle to satisfy our thirst even though we live on a water world.  That is because the Earth’s oceans are salty. Just 2.5% of the Earth’s water is freshwater, and of that, 60% is trapped in glaciers, 30% in groundwater (not all of which is accessible), and just 10% is on the surface in lakes and rivers.

NASA plans to make water and oxygen on the surface of the Moon and Mars by 2020

apollo-17-jack-schmitt

NASA is taking steps that could lead to colonization of other planets.

NASA is working on plans to make water, oxygen, and hydrogen on the surface of the Moon and Mars. It is vital that we find a way of extracting these vital gases and liquids from moons and planets if we ever want to colonize other planets, rather than transporting them from Earth (which is prohibitively expensive, due to Earth’s gravity). The current plan is to land a rover on the Moon in 2018 that will try to extract hydrogen, water, and oxygen — and then hopefully, Curiosity’s successor will try to convert the carbon dioxide in the atmosphere into oxygen in 2020 when it lands on Mars.

Top 13 ‘Futurist Speaker’ Columns in 2013

Futurist Thomas Frey: 2013 has been a year of considerable change for both me and the rest of our team at the DaVinci Institute. While most of what you see here on Futurist Speaker is about my research, thinking, and philosophy on the future, I thought this might be a good time to step back and fill you in on the people behind everything you’re reading.
