The new air conditioner consumes 40 percent less electricity than typical models and also makes drinkable water as a byproduct.
Hydrogen is a clean fuel source, and using sunlight and water is the cleanest way to produce it. Now, engineers from Columbia University have developed a “solar fuels rig” that floats on the ocean, captures energy through a solar cell and uses it to harvest hydrogen from the water beneath it.
It was back in June that we first heard about Workhorse’s SureFly, an octocopter designed to carry two people. Well, if everything works out, it will be making its first manned flight on Jan. 8th in Las Vegas, ahead of the CES trade show.
The new cooling system, which uses no electricity, could make future air conditioning and refrigeration cheaper by sending heat up into space.
Carbon dioxide–splitting techniques could store excess electricity from renewable sources
Nanotube weave can light up an LED when pulled
It seems like there’s a new graphene breakthrough coming out of the James Tour lab at Rice University almost every month. Now, researchers have managed to make graphene out of wood, by blasting a piece of pine with a laser beam.
Eco Marine Power is preparing to put its rigid solar energy sails through their paces next year. The EnergySail from EMP can harness the power of the wind and sun at the same time, for high-efficiency transport on the high seas.
Drones could fight deforestation by planting 1 billion trees a year.
E-bikes offer a way for commuters to arrive at work sweat-free, but some boosted two-wheelers are starting to offer ranges that rival bikes of the fossil fuel-powered variety. One such example is the Grunner, which boasts 2.2 kW of power and 180 km (112 mi) of range.
