How to economise your car – Doug Heffron's super-efficient 1989 Geo Metro
Anyone fretting about the pumps drying up again, should the Shell tanker drivers strike once more, might want to think about Doug Heffron’s alternative coping method rather than panic buying.
Back in 1993 when fuel prices sky-rocketed in the US, Doug home converted his Geo Metro Xfi, which already did a very reasonable 56 miles per gallon, into a rather unsightly but undeniably stripped-down and highly economical 75mpg mutant machine…

The Squirt 2 – a 100% safe 1370HP jet-powered boat
We must try very hard not to refer to the Squirt 2 jet-powered boat as a “death trap.” Every time we call an odd and dangerous-looking invention a death trap, the inventor pops up and gets quite angry about it being labelled as a death trap.
As of yet, no one has died during the testing and creation of the Squirt 2 Turbine Jet-Boat so, for all intents and purposes, it is entirely safe. You may well emerge totally alive and unscathed from a trip on the aluminium-hulled jet-propelled speedboat that generates 1370 horsepower. Here it is showing off by firing up its engine…

Top eight planet-saving gadgets for Earth Day – don't be mean, be green
If you are as yet to navigate to the Google homepage today, you may be unaware that it’s Earth Day today. Happy Earth Day everyone!
Earth Day is a day as old as the hills – even older. It’s as old as the mud the hills are made from. Earth Day started back in ancient Egypt when the villages on the banks of the Nile would celebrate the annual floods which brought silt deposits to fertilize their land.
In celebration, the villagers would throw the mud at one another in joy and to this day people still mark the event with the giving and receiving of pieces of earth.
Actually, that’s a complete lie but it was a nice story, wasn’t it? No, Earth Day is about awareness of the environment as started in 1970 by a gentleman named Gaylord Nelson and to do our part at Tech Digest we’re going to look at the best Earth-saving gadgets that money can buy…
Power dressing: Nanowire clothing to make electric energy from our movement
The 80s are back or at least that’s what I thought when I heard that the future was all about power dressing.
Un/fortunately, Professor Zhong Lin Wang of Georgia Tech is not talking about shoulder pads and trouser suits but instead has harnessed the power of nanowires to come up with materials that can convert kinetic energy into electrical current…
"Energy Saving Day was worth the effort" says the man who came up with the idea of Energy Saving Day
Matt Prescott, who’s Energy Saving Day actually saw a rise in energy consumption at the end of it, said it was still worth his effort as it helped raise awareness of the causes and led to energy companies simplifying their home insulation schemes. Awesome.
Even though E-Day clearly raised zero awareness with consumers, as everyone happily boiled more water than strictly necessary and left the oven on to keep the kitchen warm…
