DEVap – 90% More Efficient Air Conditioner

DEVap cooling system

The National Renewable Energy Lab has Done It!  As Lloyd and other sensible people keep pointing out, if our buildings and cities were better designed, we would need a lot less air conditioning, and in many cases none at all. That should be goal #1. But because it’s doubtful that’s ubiquitous A/C is going away any time soon, it can’t hurt to make the technology more efficient (keeping buildings cool is using about 5% of the energy used in the US). That’s exactly what the engineers and scientists at the National Renewable Energy Laboratory (NREL) have done.

Scientists Find Way To Obtain Drinking Water From Air Humidity

Scientists Find Way To Obtain Drinking Water From Air Humidity

Drinking water from air humidity 

Not a plant to be seen, the desert ground is too dry. But the air contains water, and research scientists have found a way of obtaining drinking water from air humidity. The system is based completely on renewable energy and is therefore autonomous.

Plant Factories – The Future of Food

Plant Factories - The Future of Food

 Lettuces are grown in a sterile environment at Ozu Corporation’s plant factory in Japan – without being exposed to the air outside

 They look more like the brightly lit shelves of a chemists shop than the rows of a vegetable garden.  But according to their creators, these perfect looking vegetables could be the future of food.

Windbelt: Small-Scale Wind Power To Help Power Third World

 Working in Haiti, Shawn Frayne, a 28-year-old inventor based in Mountain View, Calif., saw the need for small-scale wind power to juice LED lamps and radios in the homes of the poor. Conventional wind turbines don’t scale down well-there’s too much friction in the gearbox and other components. “With rotary power, there’s nothing out there that generates under 50 watts,” Frayne says. So he took a new tack, studying the way vibrations caused by the wind led to the collapse in 1940 of Washington’s Tacoma Narrows Bridge (aka Galloping Gertie).

Vertical Coastal Farms Could Use Seawater To Grow Crops In The Future

Vertical Coastal Farms Could Use Seawater To Grow Crops In The Future

 Vertical farms of the future

Thought up by Italian architecture firm Studiomobile, vertical seawater farms sticking up out of the water could covert the salt-laden liquid into freshwater for crops. It’s all about producing humidity. A series of vents would gather humidity from the seawater to cool the greenhouses and, as it collects, irrigate the crops inside.  (Pics)

Robotic Weather Planes Could Improve Weather Forecasts

Robotic Weather Planes Could Improve Weather Forecasts 

 Small, unmanned aerial vehicles, such as this 18-kilogram Boeing ScanEagle, could provide more precise data about weather systems.

Weather forecasters may not have the best reputation for accuracy, but with today’s computational modeling, it’s possible to make pretty reliable weather predictions up to 48 hours in advance. Researchers at MIT, however, believe that autonomous aircraft running smart storm-chasing algorithms could get that figure up to four days. Better weather forecasting could help farmers and transportation authorities with planning and even save lives by providing earlier warnings about storms and severe weather, says Jonathan How, principal investigator at MIT’s Department of Aeronautics and Astronautics.
