A major goal in renewable energy research is to harvest the energy of the sun to convert water into hydrogen gas, a storable fuel. Now, with a nanoparticle-based system, researchers have set a record for one of the half-reactions in this process, reporting 100% efficiency for the reduction of water to hydrogen (Nano Lett. 2016, DOI: 10.1021/acs.nanolett.5b04813).

To make such water-splitting systems, researchers must find the right materials to absorb light and catalyze the splitting of water into hydrogen and oxygen. The two half-reactions in this process—the reduction of water to hydrogen gas, and the oxidation of water to oxygen gas—must be isolated from each other so their products don’t react and explode. “Completing the cycle in an efficient, stable, safe fashion with earth-abundant elements is an ongoing challenge,” says chemist Nathan S. Lewis of Caltech, who was not involved in this study.

Until recently, the efficiency of the reduction step had maxed out at 60%. One challenge is that electrons and positive charges formed in the light absorption process can rapidly recombine, preventing the electrons from reducing water molecules to form hydrogen. To overcome this problem, several years ago, Lilac Amirav of Technion–Israel Institute of Technology and her colleagues designed a nanoparticle-based system (J. Phys. Chem. Lett. 2010, DOI: 10.1021/jz100075c) that would physically separate the charges formed during photocatalysis.

These underground farms could feed 9 billion people, using 1/3 the space of Hawaii.

A new fully-automated farm in Japan can be used to grow vegetables anywhere on Earth with little human input, but it may not yet be a solution to solve hunger, the company’s CEO told Sputnik Japan.

No source of energy is perfect and one of the traditional drawbacks of solar energy has been that it’s tough to generate new power when it’s dark outside. However, SolarCity announced this week that it’s taken a big step toward fixing this problem by agreeing to use Tesla’s 52 MWh Powerpack lithium-ion battery storage system for its massive solar power project that it’s building in Hawaii for the Kaua’i Island Utility Cooperative (KIUC). SolarCity, of course, is chaired by Tesla CEO Elon Musk so the decision to go with the Powerpack is pretty convenient for both companies.

SolarCity says it believes that its collaboration with Tesla will produce “the first utility-scale system in the U.S. to provide dispatchable solar energy, meaning that the utility can count on electricity being available when it’s needed, even hours after the sun goes down.” To be clear, using the Powerpack won’t completely eliminate the need for non-solar resources at night since it’s projected to feed up to 13 megawatts of electricity onto the grid, which will only reduce the amount of power used by non-renewable sources.

Radio Flyer has partnered with Tesla Motors to release a miniature Model S electric car for children. The vehicle has a top speed of six miles per hour, advanced battery technology, working headlights, a sound system, and other Model S inspired design elements.

The tiny cars will begin shipping in May 2016, and customers can preorder and build their little Model S now. The preorder process involves picking the color as well as optional spare batteries, a cover, and customizable license plate and parking sign.

Cyber Carjacking the new way to steal someone’s auto.

Cyber security was one of the topics on the agenda at the recent CyberTech conference held in Tel Aviv.

Last year, hackers in the US managed to remotely access a Jeep Cherokee SUV through its on-board computer, taking control of its steering, transmission and brakes.

However, one also must look at the past for insights and guidance on things that were done wrong to ensure bad history is not repeated.

Therefore, let me share with you a part of history that we need to be aware of and protect our future from ever repeating again.

Many folks have never heard of Poor Farms in the South and Poor Houses in some parts of the Midwest. Before soc. Security and Welfare we had poor farms/ houses. They date from the late 1800s until 1930s.

Poor farms/ houses were often filled with the elderly and others that had no money or anyone to take care them. People often worked the land for 16+ hours days, dressed in rags, and had very little to eat. Once you were there you could not leave ever until you died.
