Jonny Lee Tempest is an inventor, investor, retired Cirque Du Soleil Audio Engineer, certified Entertainment Electrician (ETCP-CEE) and member of MENSA.
He has owned 6 Tesla cars, has an unquenchable and insatiable thirst for doing things in new ways, and is passionate about figuring out how the future can be free of fossil fuel emissions.
Most to the point for the Electric Boat Association, he designed and built the world’s fastest pure solar electric boat. It goes 54 miles an hour and pulls a waterskier instantaneously with unmatched torque and silence.
Jonny Lee is also the founder of Net Positive, or N+, which has built a simple piece of hardware coupled with learning piece of software that helps people worry less about their energy usage, while makring their energy usage mre efficient.
You can find out more about Net Positive and how its solutions can be applied to your need on their »» website.
But before you go, check out these videos. The first shows Jonny’s electric boat rocketing along the water (almost silently) at 56 miles per hours, 48 kilometres per hour: 90 KNOTS!.
The second shows how he went about building/adapting boat motor technology to achieve this amazing accomplishment.
Germany-based torqeedo definitely makes the most stylish electric boat motors available and is a leader in performance durability as well.
Now they have increased the power on their top-end Deep Blue line of inboard and outboard motors with the introduction of 100kW motors. The 100kW motors are comparable to a 150HP fossil fuel motor.
The motors come in two versions: a low-rpm version for displacement boats and a high-rpm version for planing boats.
More powerful batteries developed with BMW
In addition, the company has launched an upgraded, higher capacity 40 kWh battery that features 30% more capacity in the same footprint and an energy density of 144 Wh per kg.
The battery has been developed in the course of adapting BMW’s i3 electric car batteries for the marine market. Among other things, the companies are partners in the ‘Malizia’, a 60’ racing yacht being optimized for the world’s toughest solo sporting competition, the Vendee Globe in 2020.
The 30% increase in energy and energy density will also extend to torqeedo’s 24V batteries, used for their line of outboard ‘Cruise’ motors. Based on the new capacity, the 24V battery gets a new name: Power 24-3500, featuring an impressive energy density of 138 Wh per kg.
A new eco dive resort in Raja Ampat has become the first to launch e-boats, an important step in the race to protect the world’s most biodiverse coral reefs.
Competition is healthy among the eco resorts of Indonesia’s most famous dive destination, Raja Ampat. And MahaRaja Eco Dive Lodge, which only opened 8 months ago, has just scored an important claim to fame.
The small luxury resort is the first in Raja Ampat—and possibly the first in Indonesia—to electrify its dive boats.
“We are the first [resort] to launch e-boats, and we sincerely hope the others will follow,” MahaRaja’s founder Mahasti Motazedi, a French former aeronautics engineer and Microsoft sales executive, tells Eco-Business.
With tourism growing rapidly Raja Ampat—although remote and expensive, visitor numbers have grown by 1,300 per cent in under a decade—the region’s reefs, the world’s most biodiverse, will hope she’s right.
Volvo Penta, the industrial and marine engine division of Volvo, has issued a clear statement of intent with the news that by 2021 it will provide electrified power solutions for both its land and sea-based business segments.
The announcement follows in the lead of the automobile division which will be ending its internal-combustion-engine only models and offer only electric and hybrid engines beginning in 2019.
Underpinned by the success of hybrid and all-electric technology introduced by the Volvo Group, Volvo Penta’s electrified solutions will demonstrate the company’s long-term commitment to offering customers the latest and most appropriate power source for their user applications.
“Volvo Penta is embracing the electric transformation and will be at the forefront in delivering compelling business cases to customers using this new technology,” said Björn Ingemanson, president of Volvo Penta.
“We are already several years into its electrification journey,” added Johan Inden, chief technology officer. “We have spent this time building competencies, experience and establishing the technologies required to deliver a sustainable power solutions road map.
Volvo Penta has restructured its organization to accelerate the switch towards electrified power and has committed to an ambitious ramping up of its electrification investment program. An electromobility development-and-test laboratory has also been established at its Swedish headquarters.
Volvo Penta is a Tier 1 partner to many leading equipment manufacturers in the marine and industrial segments, so it is in a unique position to further develop the proven electric platforms from the Volvo Group.
While the power outputs and applications of the initial electric systems are being kept confidential for the time being, the company has announced that both hybrid and all-electric solutions will be offered at the outset. Volvo Penta is already field testing early prototypes and system validation is under way.

It’s a delightful, whimsical video that ends with the successful completion of a very cool electric boat.
Back in 2008 an upstart company called Tesla was just introducing an electric car it called The Roadster.
Electric cars were a novelty at the time, and electric powered boats even more so. But out on the water that year, a maritime speed record of 76.8 MPH (122 kmh) was being set. And it wasn’t until last week, a full decade later, that the record was broken when Jaguar took some of the learning from their Formula E car racing experiences and teamed up with boat manufacturer Vector to create a boat that hit 88.6 MPH (142 kmh) over a 1 mile stretch on the tranquil waters of England’s Coniston Water lake.
Vector has been involved in powerboat racing since 2012, and is the most watched powerboat racing team in the world, with 600K social media followers.
Jaguar, of course, is Jaguar, and only got back into auto racing in 2016 when it became the first premium manufacturer to join the Formula E series. Its Panasonic Jaguar team with drivers Nelson Piquet Jr. and Mitch Evans sits in 5th place coming in to the last race of the season in New York on July 14 and 15.
The Jaguar V20E boat that set the record was piloted by Jaguar/Vector co-founder Peter Dredge and everyone is pretty tight lipped about the specifics of the motor, battery and controller, which was developed in concert with Williams Advanced Engineering. Check out the video below for as many details as can be gleaned.
In a press release last October the team made it clear that they would be pushing the boundaries of marine speed records, so we probably have not seen the last of this.
As for electric boats in general, there has not been a lot of companies jumping into the water, but the German company Torqueedo has a range of e-motors and announced they have teamed up with BMW on an entry in sailing’s Vendée Globe solo, around-the-world race in 2020. The SeaBubble battery powered hydroplane (photo above) was launched on the Seine river in Paris in early June.
