Many hybrid cars feature regenerative braking - they harness the energy generated when they brake, and store it in the battery for later use. This helps maximize the amount of time that the car can run on one charge. One can't help but wonder, then, how much energy could be harvested from heavy-duty construction, mining and agricultural machines, as they go about their business. A group of researchers from Finland's Aalto University decided to find out, and reportedly ended up cutting those machines' fuel consumption by 50 percent.
The Aalto team added electric power transmission systems (including motors) to a variety of existing internal-combustion non-road mobile machines, effectively turning them into hybrids. Unlike cars, these machines don't spend much time in stop-and-go traffic, so braking was not their primary energy-generation source. Instead, the majority of the energy came from work-related activities such as deceleration, and the lowering of loads.
The researchers are still in the process of determining which other actions provide the most energy.
By running partially on battery power derived from energy that they themselves generated, the test rigs use a claimed 50 percent less fuel. Such hybrid technology could also lead to lower emissions, better control, and more flexibility in the machines' design. Additionally, unused stored energy could be released into the grid.
Virtually ALL of his equipment was diesel-electric hybrid.
He pioneered the use of rubber tires in heavy equipment and used rack&pinion,leverage and other techniques instead of hydraulics. Everything was designed to function with a minimum amount of parts support from the factory- instead of the greedy opposite. He gave 90% of his income to worldwide Christian work- building trade schools and hospitals as well as churches. He called it \"Christianity with its sleeves rolled up\". He never finished 6th grade in school yet constantly confounded the engineers that said his design proposals were impossible and would never work. He designed and perfected the first mobile offshore drilling platform. He himself said that he was only... \"A mechanic that God had Blessed\".
I only said all that to say this to these researchers and anyone else who\'s interested- Much has been already done yet forgotten that we should be reconsidering. Mr.Letourneau said that every generation of inventors and innovators stands on the shoulders of those who have gone before them. If we look to the ancients such as Archimedes and more recently,Newton and others, perhaps we should be looking a little more closely at some of the forgotten men of more recent times.
R.G.Letourneau\'s autobiography is called, \"Mover of Men and Mountains\". He is one of my heroes and has a lot more practical advice and ideas to share than just about anybody I know of throughout the modern industrial era.
I would love to collaborate with their team on a project if interested- combine their tech and ours to see what the results of run time would be...
From Wiki \"...In 1958,... LeTourneau re-entered the earthmoving equipment manufacturing business, offering..... a range of high capacity earthmoving, transportation, and material handling machines based on the revolutionary electric wheel drive system he had developed.\"
