hemp batteries better than lithium and graphene

The comparison has only been proven on a very small scale. (You weren’t expecting a Silicon Valley conglomerate to do something genuinely groundbreaking were you? They mainly just commercialise stuff that’s been invented or at least funded by the state.) But the results are extremely promising.
The experiment was conducted by Robert Murray Smith – who has built up quite a following on his YouTube channel – of FWG Ltd in Kent. He observed a Volts by Amps curve of both the hemp and lithium batteries and found that the power underneath the hemp cell was a value of 31 while that of the lithium cell had a value of just 4. Although he does not claim to have proven anything, he said that the results of his experiment showed that the performance of the hemp cell is “significantly better” than the lithium cell.
It comes as no real surprise, which is presumably why he conducted the experiment. In 2014, scientists in the US found that waste fibres – ‘shiv’ – from hemp crops can be transformed into “ultrafast” supercapacitors that are “better than graphene”. Graphene is a synthetic carbon material lighter than foil yet bulletproof, but it is prohibitively expensive to make. The hemp version isn’t just better, it costs one-thousandth of the price.

The scientists “cooked” leftover bast fibre – the inner bark of the plant that usually ends up in landfill – into carbon nanosheets in a process called hydrothermal synthesis. “People ask me: why hemp? I say, why not?” said Dr David Mitlin of Clarkson University, New York, in an interview with the BBC. “We’re making graphene-like materials for a thousandth of the price – and we’re doing it with waste.”
Dr Mitlin’s team recycled the fibres into supercapacitors, energy storage devices which are transforming the way electronics are powered. While conventional batteries store large reservoirs of energy and drip-feed it slowly, supercapacitors can rapidly discharge their entire load.
This makes them ideal in machines that require sharp bursts of power. In electric cars, for example, supercapacitors are used for regenerative braking. Releasing this torrent requires electrodes with high surface area, one of graphene’s many phenomenal properties.
Mitlin says that “you can do really interesting things with bio-waste”. With banana peels, for example, “you can turn them into a dense block of carbon – we call it pseudo-graphite – and that’s great for sodium-ion batteries. But if you look at hemp fibre its structure is the opposite – it makes sheets with high surface area – and that’s very conducive to supercapacitors.”

I was thinking about that after seeing that car that didn't stay put on the boat ramp. I would like to check it out just to see what the noise level is because there is no disputing radial engines are noisy and turboprops are not efficient on short hops.At the moment I simply don't see them having the weight capacity to carry a full load of people and enough battery to both cross the straight and provide the required fuel safety margin.

LOS ANGELES - Tesla CEO Elon Musk made his first courtroom appearance Tuesday as a defendant in the defamation case stemming from a 2018 tweet in which he called a man "pedo guy."

The target of Musk's insult was Vernon Unsworth, a British diver who took part in the 2018 rescue operation that freed 12 boys on a soccer team and their coach after they became trapped inside a cave in Thailand.

Musk and Unsworth had clashed at the height of that mission. Afterward, the Tesla executive lobbed the insult at the diver on Twitter.


Lawyers for Unsworth argued that the remark was widely interpreted as Musk suggesting the diver was a pedophile. Musk has denied that assertion, saying the phrase is a common expression in South Africa, where he was born. Musk's lawyers unsuccessfully sought to have the case thrown out before trial.

The proceedings began with jury selection on Tuesday. Several potential jurors were dismissed, with many disclosing professional connections to Musk and his various companies, including SpaceX, The Boring Company, and Neuralink. The Guardian reported that one person was sent home after saying he had a coming job interview with SpaceX and that a woman was sent away when she said she held "strong opinions about billionaires."

After opening statements, Musk took the witness stand and offered some insight into what led to his 2018 feud with Unsworth.

The Tesla CEO told the court he was incensed by an interview Unsworth gave to CNN after the rescue, in which a minisub Musk sent to the divers went unused. Unsworth called Musk's attempts to get involved in the mission a "PR stunt" while the rescuers were busy developing a plan to remove the boys and their coach from the Tham Luong cave in northern Thailand.

Unsworth told CNN that Musk "can stick his submarine where it hurts." In court, Musk said Unsworth's remarks hurt him.

"So I insulted him back," Musk testified, adding: "I didn't literally mean he was a pedophile."

Lawyers challenged Musk on that assertion, pointing to a follow-up tweet in which Musk said, "Bet ya a signed dollar it's true," in reference to his original tweet. The tweets were deleted hours after he posted them in 2018.

Elon Musk tells jury he's worth US$20B, but is short on cash

Dana Hull, Edvard Pettersson and Tom Metcalf, Bloomberg News




Elon Musk says he doesn’t have a lot of cash.

Musk’s wealth came up in the second day of his testimony before a federal jury in Los Angeles where the Tesla Inc. and SpaceX chief executive is on trial over a tweet in which he referred to a British cave expert as a “pedo guy.”

After an unsuccessful objection from his lawyer, Musk told the jury he has Tesla stock, and SpaceX stock, with debt against those holdings, and his net worth is about US$20 billion. But contrary to public opinion, he said, he didn’t have much cash. Musk finished testifying after a total of about six hours on the stand over two days.

Caver Vernon Unsworth sued Musk over the “pedo guy” tweet, which the CEO called “a flippant, off-the-cuff insult.” Musk said he was responding to Unsworth’s criticism of Musk’s effort to help rescue members of a Thai soccer team from a flooded cave in 2018. Musk and engineers at his companies prepared a mini submarine to help with the rescue efforts. The 12 kids, aged 11 to 16, and their coach were ultimately saved without the sub.

Usnworth, who knew the caves well, ridiculed the high-profile effort from Musk. He told CNN that Musk could “stick his submarine where it hurts” and called the idea a PR stunt with no chance of working.


That angered Musk, who said a team of engineers worked very hard to build the sub to save the boys. He said Unsworth’s comments denigrated the efforts of his team.

Thai rescue officials were “very happy” with his team’s effort and the government thanked him for it, Musk said, contradicting Unsworth’s comments in the CNN interview.

Musk also explained to the jury his penchant to tweet. (He retweeted a Tesla post during a break in his testimony.)

His "assets" are shares in companies that have never turned a profit and stay in business mostly on government grants and tax incentives. How many people know that you can sell a tax loss for cash?

LOL where do you come up with this nonsense?

Musk is the 41st wealthiest man on Earth.

Came to Canada as an immigrant at 17

I can see why the white nattys would hate him

Oil industry schills believe that it will all go away if they had mouth people like Musk. It's sort of pathetic, really.

Was probably cheaper than a new battery.

The car storage becomes part of the grid. They act to expand and extend storage capacity.
