Blockchain or DLT-based Voting Considered by US Senate as an Alternative to Traditional Methods During COVID-19 Crisis

The Coronavirus (COVID-19) outbreak has made it quite difficult for the United States Congress to conduct meetings and deliberate. Lawmakers have offered suggestions regarding how to keep things going during the ongoing crisis. As mentioned in a Senate memo posted on April 30, 2020, blockchain-based voting might be part of the solution…

With its encrypted distributed ledger, blockchain can both transmit a vote securely and also verify the correct vote. Some have argued that these attributes make blockchain useful for electronic voting broadly. Blockchain can provide a secure and transparent environment for transactions and a tamper-free electronic record of all the votes.

Elon Musk Eyes UK Electricity Market As Tesla Posts 32% Q1 Revenue Uptick

Electric vehicle manufacturer Tesla’s (NASDAQ:TSLA) TSLA financials are often accompanied by colorful events, be it controversial Twitter quips by its founder Elon Musk or bold corporate announcements of some descriptions. As it turns out, the run-up to the publication of the company’s latest financials did not disappoint and to a certain extent neither…


Greener future: These 10 ambitious tech startups are working toward a sustainable world

As the challenge of global warming is posing a serious threat to the environment, many tech entrepreneurs are coming up with concepts focused on sustainability. Aspirational and young entrepreneurs are highly inclined towards minimalism, zero waste, and other initiatives that will bring about sustainability in the tech ecosystem…


U.S. Considered Blockchain When Sending Relief Money

Members of Congress are urging Treasury Secretary Steven Mnuchin to use the blockchain to send out Americans’ stimulus payments. The request is coming a little late considering about 80 million people have already gotten their stimulus money by direct deposit. In addition, several other checks are already in the mail and making their way…

Utilize private sector innovations such as blockchain and DLT [distributed ledger technology] to support the necessary functions of government to distribute and track relief programs and direct that all guidance support the use of technology to facilitate delivery of CARES Act benefits.


Swiss environmentalists demand ‘green recovery’ after coronavirus

BERN (Reuters) – Environmental activists delivered a petition to a special session of the Swiss parliament on Monday demanding that a government aid package should promote a “green recovery” from the coronavirus crisis. With some lawmakers wearing protective face masks, parliament convened at an exhibition centre rather than…

We are here because we want to make it a green recovery. We need to foster measures that help us to quit fossil fuels now in the wake of corona.

DLT Is The Foundational Technology Of The Second Digital Era, Says Don Tapscott

Don Tapscott, co-founder of the Blockchain Research Institute (BRI) believes Distributed Ledger Technology is the second digital era’s underlying technology. Tapscott during his Virtual Blockchain Week presentation talked regarding the shift to the internet of value from the internet of information. He is also a prominent author in technical…


Can Lessons From The Commercial Space Program Fast-Track Fusion As A Clean Energy Solution?

Fusion—the energy source of the stars—would be clean, green, safe and abundant. But there’s one problem. It’s really hard to do. The U.S. Department of Energy (DOE) is currently exploring “Public-Private Partnership” programs for fusion energy, learning from the success of these programs in stimulating the private space industry. Could this provide…


EU solar generation jumps 28% year-on-year in month of lockdown

Dynamics set in motion by the COVID-19 crisis and weather patterns have mixed to push EU solar generation to new heights, amid talk by analysts that the jump evidences the need for flexibility. Over the past few weeks, analysts had documented various solar generation milestones across individual European countries, with Germany, Spain and…

Electricity systems must become much more flexible to absorb higher levels of wind and solar in the future, including through ‘responsive demand’ that can shift to when power is cheap.


Peer-to-Peer Electric Car Charging Is Wild—and Possibly Revolutionary

Could the Napster of electric cars eliminate the need for charging stations altogether? A wild new concept uses the strengths of autonomous electric car designs to pair them for sharing a charge on the go. In IEEE Spectrum, senior editor Philip Ross writes that the idea is like an existing refueling model…

Jet fighters can’t carry a huge tank of fuel because it would slow them down. Instead they have recourse to air-to-air refueling, using massive tanker planes as their gas stations.

Tesla researchers publish work on hybrid battery enabling all-electric car range extender

Tesla, through its research arm in Canada, has published the results of research on Hybrid Lithium-Ion/Lithium Metal Cells, which can be used to create what can be best described as all-electric cars with a range extender. Typically, when we talk about electric vehicles with a range extender, we are talking about a battery-powered electric…

Increasing the energy density of batteries will decrease the cost of electric vehicles and enable longer driving ranges. Replacing the graphite anode in conventional lithium-ion cells with lithium metal significantly increases energy density. However, lithium metal anodes are plagued with rapid capacity loss and short cell lifetime. To develop a high energy density cell with longer lifetime, we propose a hybrid lithium-ion/lithium metal cell that is achieved by purposefully plating lithium metal on graphite.

Diamond nanothreads could beat batteries for energy storage, theoretical study suggests

Computational and theoretical studies of diamond-like carbon nanothreads suggest that they could provide an alternative to batteries by storing energy in a strained mechanical system. The team behind the research says that nanothread devices could power electronics and help with the shift towards renewable sources of energy…

We expected a good mechanical energy storage capability [for carbon nanothreads]. But surprisingly we found its energy density can be up to three times the lithium-ion battery in theory.
