Learn all about renewable energy transportation at The Mt. Washington Auto Road, this month.

It will be celebrating the 40th year of the ALT Energy Summit, on July 25.

The event is free to the public.

The ALT Energy Summit is one of the largest gatherings of renewable energy transportation in New England.

It features major manufacturers of electric vehicle, industry suppliers and individual “makers” and inventors.

The Auto Road itself continues as a proving ground and playground for new and evolving technologies.

The list of builders, manufacturers and organizations attending this year’s event may be the most impressive to date with vehicles such as the first bacon-fueled bio-diesel motorcycle.

The Hormel “Driven By Bacon” motorcycle, built to tour the U.S., and promote the launch of its new “Black Line” bacon in the Driven by Bacon U.S. tour, is sure to attract a crowd. The bacon bio-diesel bike is reportedly nearly carbon-neutral, meaning it contributes almost zero emissions to the environment.

Entropy Racing, a veteran of the Mt Washington Climb to the Clouds race with Tim O’Neill at the wheel, will return for a fascinating account of their experience at Pikes Peak – including their crash and loss of one of three cars in practice.

Entropy builds and races the revolutionary Electric Vehicle Sports Racer, which has set new standards for affordable, safe and environmentally friendly racing.

To help celebrate the event’s history, Entropy will allow people to drive a fully race-prepped electric race car to the summit of Mount Washington or around the grounds at the base of the Auto Road.

To drive to the summit there will be a fee and speed will be limited to comply with Auto Road regulations.

Jeff Disinger will also be present with the bike that set the land speed record, Electrafunk Racing’s Electracutioner.

Visitors can watch the parade of vehicles in the Auto Road’s main field, follow them to the summit as they make their bid to get there first, or stroll the field and chat with owners and builders once they return.

Presentations at 1 p.m. and 2:30 p.m. are free and open to all.

“We’re delighted to celebrate 40 years of innovation and experimentation in renewable transportation”, said Howie Wemyss, general manager of the Mt Washington Auto Road. “The event started in the years of the energy crisis of the mid ’70s, and what was then considered “alternative” and slightly off-beat, is now mainstream, as can be seen by the plug-in electric, hybrid, and biodiesel vehicles that come to our event every year. The Mt. Washington Auto Road has seen the evolution of transportation play out on its eight-mile path to the summit. Today, that evolution leads to a future that is 100 percent renewable.”

Saturday’s schedule begins at 8 a.m. with breakfast at the Great Glen base lodge leading up to the regatta parade preparation, exhibitor and participant setup at 9 a.m.

At 10 a.m., the pedal-powered vehicles will begin the parade to the summit followed all other vehicles by 11 a.m. By 1 p.m., all participants will return back down to the base area from the summit attempt for exhibition, demonstrations and reports from their summit trip.

At 1 p.m. Saturday  the “Three Amigos of Electric Motorcycles,” Terry Hershner, Ben Rich and Stéphane Melançon, world record holders and legends in the electric motorcycle community, will give a talk on their tech innovations, work with streamlining, charging and legendary feats of endurance and distance.

Also, Troy Rank, Guinness World Record holding e-bike distance rider will be showing off his latest creation, the Maxwell Motorbikes EV0, and will talk about his world record-setting exploits.

Saturday afternoon at 2:30 p.m., EVSR’s Charlie Greenhaus and the Entropy Racing team return to the scene of their first world-class hillclimb victory to talk about their recent conquest of Pikes Peak. It includes crashes, hail, sleet and cheers as they placed third and fourth in their class.

Presenting sponsor, NH Electric Co-op, represented by Gary LeMay, will be on hand to answer New Hampshire renewable and sustainable energy questions and show off their plug-in electric Line Truck.
