Quirky Inventions from the Geneva Gadget Fair

A hands-free umbrella, parachutes for aeroplanes and other quirky inventions went on display this week at the opening of the world’s biggest fair for new gadgets.

Even the ribbon-cutting was done by a humanoid robot.

A thousand inventions all had their debut in Geneva, Switzerland, including a robotic claw hand, a high-tech screen to play simulated golf and a ball designed to protect its user from electromagnetic waves generated by wi-fi and other household devices.

Television, radio and microwaves all use electromagnetic waves that vary according to wavelength, energy and frequency.

Sound Advice for the DIY Renovation Novice

Broken pipes, sagging ceilings and bruised egos are some of the lesser casualties of projects gone wrong, and if you believe the stats, around half of all DIY projects end in disaster.

Paying to fix a botched job – and dealing with smug tradies – will quickly wipe out any potential savings and brownie points.

So question whether you really have the time, tools and ability to pull off a major DIY project or renovation before you reach for the sledgehammer. And heed the following advice from those who have survived it.

1. Planning and managing

It’s a fact: your planning and project management skills will make or break a renovation – as well as a marriage. So quit now if you don’t think you’re up to it. Research should be exhaustive and your plan as detailed as possible. Divide your wish list into three categories: essential, optional and desirable. Then get out the red pen.

Work out a time line and budget, allowing for a 20 per cent contingency. Make sure you get any required planning approvals and owner-builder certificates.

You’ll have a better shot at domestic harmony if you divvy up the major tasks: one manages the budget, the other oversees the tradies and timeline. And both share the drudgery of chores and daily clean up.

America’s Oldest Net-Zero Home

 
Turning a century-old Victorian house into a net-zero home might sound like an ambitious goal for a young couple in their first home, but Kelly and Matt Grocoff, a self-described “average couple” from Ann Arbor, Michigan, did just that, and now own the oldest home in America to achieve net-zero energy. In 2006, when Matt and Kelly bought their 1901 home in a walkable, historic neighborhood, they knew they wanted to go net-zero someday, but they didn’t imagine they would be producing more energy than they use in five short years.

“It was just a fantasy at the time we started looking for a house,” says Matt, a longtime green-building enthusiast and net-zero energy consultant who founded and hosts GreenovationTV. “We wanted to find an old house with good bones and restore it, then work toward net-zero. I thought net-zero would be 10 years away, but before we knew it, all the stars aligned with incentives and everything else, and we were able to get our solar panels up in 2010,” he says.
Energy Basics
Matt and Kelly were motivated to take on their efficiency overhaul because they wanted to help reduce our nation’s overall carbon footprint. “There are 130 million homes in the U.S. right now, and they account for almost a quarter of our greenhouse gas emissions,” Matt says. “We realized that even if every single new home from here on out were built to net-zero energy, it would do nothing to reduce our current carbon emissions.” Read more: http://www.naturalhomeandgarden.com/green-homes/solar-homes/net-zero-home-zmfz12mjzmel.aspx#ixzz1rw1Ee4Lm
