The legendary hacker George Hotz, known by his nom de guerre “geohot,” who first came to public attention by hacking Apple’s (AAPL) first iPhone, spoke this morning at the South by Southwest conference about taking on Tesla’s (TSLA) self-driving car initiatives with his own garage efforts, a talk titled “I built a better self-driving car than Tesla.”

By the end of the talk, it was clear he had numerous targets, including Alphabet’s (GOOGL) self-driving car efforts, despite mighty respect for the search giant.

Hotz’s achievement, rigging up home made parts to an Acura ILX to make it self-driving, first came to prominence with an article in mid-December by Bloomberg’s Ashlee Vance.

The U.S. solar market is expected to grow 120% this year with 16GW of new solar power, more than double the record-breaking 7.3GW installed in 2015.

Imagine a world with little or no concrete. Would that even be possible? After all, concrete is everywhere—on our roads, our driveways, in our homes, bridges and buildings. For the past 200 years, it’s been the very foundation of much of our planet.

But the production of cement, which when mixed with water forms the binding agent in concrete, is also one of the biggest contributors to greenhouse gas emissions. In fact, about 5 percent of the planet’s greenhouse gas emissions comes from concrete.

The three solar micro-grids, with combined capacity of 35 kilowatts, were installed in the communities of Harkapur in Okhaldhunga district, and Kaduwa and Chyasmitar in Khotang District, as per a statement issued today. They will provide a 24-hour reliable electricity supply to around 540 people in 83 households and 25 local businesses.

“Nearly a quarter of Nepal’s population has no access to electricity and rely heavily instead on kerosene in particular. Since most of them live in remote areas, there is little possibility of connecting to the national power grid in the near future,” said Jiwan Acharya, senior energy specialist at the Asian Development Bank (ADB). “The solar micro-grids that we are piloting here provide a clean, cost-effective, local solution involving private sector that will change the lives of these communities and serve as a model for other far-flung villages.”

Electricity costs for households are forecast at $4 to $6 per month. Currently households relying on kerosene for lighting alone, can pay up to $10 a month. And by using solar power rather than fossil fuels, the project will avoid 41 tonnes of carbon dioxide emissions every year.

Researchers in the US have proposed a new form of wind power: small, artificial, mechanical trees capable of producing energy from their vibrations. Working with the natural breeze, or small movements caused by other factors, the scientists hope that new forms of renewable energy can be developed in the future.

The idea is to create a device that can convert random forces – whether that’s from the footfall of pedestrians on a bridge, or a passing gust of wind – into electricity that can be used to power devices. And the researchers have found that tree-like structures made from electromechanical materials are perfect for the task.

“Buildings sway ever so slightly in the wind, bridges oscillate when we drive on them and car suspensions absorb bumps in the road,” said project leader Ryan Harne from Ohio State University. “In fact, there’s a massive amount of kinetic energy associated with those motions that is otherwise lost. We want to recover and recycle some of that energy.”

The Roll-Array is easily towable by a standard 4×4 vehicle such as a Land Rover. When connected to the back of the car, the flexible solar panels are pulled out of a spool and create ground cover in a matter of minutes. On their website, Renovagen claims the panels will be able generate up to 100kWp – 10 times more power than other transportable solar panels on the market today.

Government’s other big NextGen Program “Advanced Research Projects Agency-EnergyAdvanced Research Projects Agency-Energy” (ARPA) is funding a personal climate change solution with robots, foot coolers, etc. There is one fact; US Government does love their acronyms.

Why heat or cool a whole building when you could heat or cool individual people instead?

Two big problems have been vexing environmental scientists for decades: How to store solar energy for later use, and what to do with CO₂ that’s been captured and sequestered from coal plants? Scientists from General Electric (GE) could solve both those problems at once by using CO₂ as a giant “battery” to hold excess energy. The idea is to use solar power from mirrors to heat salt with a concentrated mirror array like the one at the Ivanpah solar plant in California. Meanwhile, CO₂ stored underground from, say, a coal plant is cooled to a solid dry ice state using excess grid power.

When extra electricity is needed at peak times, especially after the sun goes down, the heated salt can be tapped to warm up the solid CO₂ to a “supercritical” state between a gas and solid. It’s then funneled into purpose built turbines (from GE, naturally) which can rapidly generate power. The final “sunrotor” design (a prototype is shown below) would be able to generate enough energy to power 100,000 homes, according to GE.
