An EV Conversion Engineered As A Drop-in Replacement

Posted by in categories: engineering, sustainability, transportation

With electric vehicles such as the Tesla or the Leaf being all the rage and joined by fresh competitors seemingly every week, it seems the world is going crazy for the electric motor over their internal combustion engines. There’s another sector to electric traction that rarely hits the headlines though, that of converting existing IC cars to EVs by retrofitting a motor. The engineering involved can be considerable and differs for every car, so we’re interested to see an offering for the classic Mini from the British company Swindon Powertrain that may be the first of many affordable pre-engineered conversion kits for popular models.

The kit takes their HPD crate EV motor that we covered earlier in the year, and mates it with a Mini front subframe. Brackets and CV joints engineered for the kit to drop straight into the Mini. The differential appears to be offset to the right rather than the central position of the original so we’re curious about the claim of using the Mini’s own driveshafts, but that’s hardly an issue that should tax anyone prepared to take on such a task. They can also supply all the rest of the parts for a turnkey conversion, making for what will probably be one of the most fun-to-drive EVs possible.

The classic Mini is now a sought-after machine long past its days of being dirt-cheap old-wreck motoring for the masses, so the price of the kit should be viewed in the light of a good example now costing more than some new cars. We expect this kit to have most appeal in the professional and semi-professional market rather than the budget end of home conversions, but it’s still noteworthy because it is a likely sign of what is to come. We look forward to pre-engineered subframes becoming a staple of EV conversions at all levels. The same has happened with other popular engine upgrades, and no doubt some conversions featuring them will make their way to the pages of Hackaday.

The World Needs Nuclear Power, And We Shouldn’t Be Afraid Of It

Posted by in categories: information science, nuclear energy, sustainability

Although many different approaches have been proposed to address this problem, it’s clear that any sustainable, long-term solution will include one important component: a transition to energy sources that don’t result in additional carbon dioxide emissions. While most of the ideas put forth — such as the hypothetical Green New Deal — focus on renewable energy sources like solar and wind power, there’s another option that we should seriously reconsider: nuclear fission power.


As we embrace green solutions, nuclear should absolutely be part of the equation.

A Norwegian Startup Is Turning Dry Deserts Into Fertile Cropland

Posted by in categories: climatology, sustainability

The UN population forecast predicts that by 2050 there will be almost 10 billion people on the planet. They’ll live mostly in cities and have an older median age than the current global population. One looming questions is, what will they eat?

The Green Revolution of the 1960s used selective breeding to double crop yields of rice and wheat in some areas of the world, rescuing millions of people from food shortages and even famine. Now, the fast-growing global population combined with the impact of climate change on our ability to produce food—increased droughts and extreme weather events many crops can’t withstand—points to the need for another green revolution.

Luckily there’s already one underway. It’s more decentralized than the last, which makes sense given there are different challenges surfacing in different parts of the world. A Norwegian startup called Desert Control has a running start on solving a problem that’s only likely to get worse with time.

Las Vegas City Planning Commission approves The Boring Company’s downtown tunnel expansion plans

Posted by in categories: Elon Musk, robotics/AI, sustainability, transportation

Elon Musk founded The Company “to solve the problem of soul-destroying traffic.” He envisions a network of tunnels where Autonomous Electric Vehicles (AEV) can transport passengers at high speeds through an underground transportation system called “Loop”. The Company’s AEVs are made up of modified Tesla Model 3 and Model X. These zero-emission vehicles will shuttle passengers through the tunnels at approximately 150-miles per hour. The first set of underground roads are under construction at Las Vegas Convention Center (LVCC). The tunneling project is almost finished. According to city officials it will be operational by January 2021. The Company plans to expand the LVCC Loop transportation system to other parts in Las Vegas. The Company submitted a proposal this year to the Las Vegas City Planning Commission to expand the tunnel to the downtown area.

On Tuesday, the Las Vegas City Planning Commission held a meeting in which the company received approval to connect the LVCC center set of tunnels to a future tunneling system that will lead downtown. The Commission gave the green light during a meeting, video below. The city council plans to review the proposal to cast a final vote in December. The downtown tunnel will begin at the LVCC, run through Las Vegas Boulevard, connect to Ogden, and lead back into Main Street. The City of Las Vegas shared via Twitter the map of where the tunnel will be built, pictured below.

Space solar power station a step closer thanks to government project

Posted by in categories: government, solar power, space, sustainability

Solar power stations in space that beam ‘emission-free electricity’ down to Earth could soon be a reality thanks to a UK government funded project.

Above the Earth there are no clouds and no day or night that could obstruct the sun’s ray – making a space solar station a constant zero carbon power source.

Tesla loves Veterans: Here’s how the company has honored military heroes

Posted by in categories: military, sustainability

On this Veteran’s Day 2020, Teslarati thanks all of the heroes who have sacrificed their freedoms to protect ours. In the theme of the day, we decided to take a look back at how Tesla has honored the heroes who have served in the military over the years. From camo-inspired EVs to Veteran’s hiring programs, the electric automaker has portrayed an appreciation for those who fought to keep us free.

2014: The Camo Model S and a heartfelt “Thank You”

In 2014, Tesla tweeted several photographs of a military-inspired Model S, dawning images of American flags and spelling the words “U.S.A. Veteran,” “Made in the USA,” and “#TeslaVets.” The camo Model S hasn’t made an appearance since then. However, the message is still present on Tesla’s official Twitter page, reminding everyone that the company is overwhelmingly supportive of our Veterans.

A new and efficient way to create nanographene for power and display devices

Posted by in categories: chemistry, particle physics, solar power, sustainability

Nanographene is a material that could radically improve solar cells, fuel cells, LEDs and more. Typically, the synthesis of this material has been imprecise and difficult to control. For the first time, researchers have discovered a simple way to gain precise control over the fabrication of nanographene. In doing so, they have shed light on the previously unclear chemical processes involved in nanographene production.

Graphene, one-atom-thick sheets of carbon molecules, could revolutionize future technology. Units of graphene are known as ; these are tailored to specific functions, and as such, their fabrication process is more complicated than that of generic graphene. Nanographene is made by selectively removing from organic molecules of carbon and hydrogen, a process called dehydrogenation.

“Dehydrogenation takes place on a such as that of silver, gold or copper, which acts as a catalyst, a material that enables or speeds up a reaction,” said Assistant Professor Akitoshi Shiotari from the Department of Advanced Materials Science. “However, this surface is large relative to the target organic molecules. This contributes to the difficulty in crafting specific nanographene formations. We needed a better understanding of the catalytic process and a more precise way to control it.”
