Modern twist to ancient technology

In an industry as mature as freight delivery, disruptive innovation is a rare thing. Tom Austin-Morgan talked to the scientist looking to an ancient form of technology that could provide a greener ...


Built for battle - Robot Wars' revamped House Robots

The return of Robot Wars to our screens this summer had completely re-engineered house robots, which were needed to keep up with the competition. Justin Cunningham finds out how the technology has ...



No shred of compromise

Designing a waste shredding machine is something of a black art. Tim Fryer found out from Untha how clever design can make dramatic improvements in performance.


Car batteries go the extra mile

One of the challenges of electric cars has always been to make the economics stack up. If worn out batteries still had a value that would help and reinforce environmental credentials.


Clean image for dirty diesel

Diesel engines have got a bad press in recent years, but there is a lot of work going on to make sure that strict environmental legislation is being met.


Digging the new breed

When you already have your place in history for a particular design, is it easier to evolve what you have rather than diversify and innovate? Tim Fryer went to visit JCB to see how it is keeping it ...

On track for bumper harvest

A tractor’s life is not an easy one, but having tracks rather than wheels appears to be making life easier. However, designing these tracks is not a straightforward task as one manufacturer found out.


Buffer system design gets software boost

Big mobile machines often need more than just standard braking to stop them. Designing the appropriate buffer solution for such equipment is a skill set in its own right, as Tim Fryer reports.


Blade cuts compressor costs

The hiss of compressed air can be heard in almost every industrial environment, but is this resource so familiar that we have not challenged its efficiency? Tim Fryer looks at a solution that claims ...
